Overview of Year<br />
Your first experience of the new season will begin with summer class. The class is<br />
designed to get you familiar with the head coach and your teammates. You will be tested<br />
and introduced to some fundamentals of tactics. Your technical abilities will be assessed<br />
and your overall fitness will be improved. This year the class starts July 9, <strong>2012</strong> and will<br />
role right into your regular fall training and season. You will have an opportunity to get a<br />
physical done on this day or within a few days of it, if you have not already received one.<br />
More in<strong>for</strong>mation will be e-mailed to your prior to this. This year there will be no break<br />
between these class / programs. This is great <strong>for</strong> a continuation of periodization training<br />
program as you will be given cross training opportunities. Leading up to this class<br />
however, you will most likely have some time off. During this time off, it will be your<br />
responsibility to recover if need be, to maintain your fitness and your play, as you will be<br />
severely challenged when you arrive in CAMP on the assigned date. If you did not<br />
attend summer class you will be first introduced to all at the first class meeting in:<br />
FALL SOCCER DOUBLE DAYS CAMP:<br />
This year the class will first meet: WEDNESDAY AUGUST 15, 2011<br />
You should arrive at: 9 AM<br />
Where: <strong>Soccer</strong> Field, Fremont Central Park<br />
More details on your first day in FALL SOCCER DOUBLE DAYS CAMP will<br />
be explained later. There are no try-outs, all interested students and able to demonstrate<br />
exceptional skills will be accepted into the class and camp. However, we will only suit<br />
between 20 and 22 players <strong>for</strong> games. There<strong>for</strong>e, playing in games will be a competitive<br />
selection process. There are no guarantees you will play in a game, but you will be part of
7<br />
the class and expected to participate in all events unless the coaching staff has deemed<br />
you not ready <strong>for</strong> participation, or you have failed to qualify <strong>for</strong> the class <strong>for</strong> other<br />
reasons.<br />
You will be asked to participate in fundraisers during season, including a golf<br />
tournament in September that will benefit the entire athletics program. Each player will<br />
need to contribute to this, either financially or through donations or by finding sponsors.<br />
You will have the chance to buy <strong>Ohlone</strong> gear, please see team web page. These sales will<br />
help support our program. We hope that you will buy at least two items. You will be<br />
asked to find sponsors <strong>for</strong> the program as well. Please see sample letter in this packet.<br />
Additionally, you will be asked to help with concessions sales and in maintaining our<br />
clubhouse. Other activities will be announced during the season. You will be issued<br />
equipment at the end of week one, assuming you have completed the first week of<br />
CAMP. You must keep your gear clean and return it at seasons end. Failure to do this<br />
will result in a hold on your academic records until returned or paid <strong>for</strong> completely. At<br />
this time we ask that you complete and submit to the Head Coach your OHLONE<br />
MEN’S SOCCER PERSONAL INVENTORY <strong>for</strong>m.<br />

ATH or PE classes. Your coaches will keep you advised. Your team will be scheduled<br />
<strong>for</strong> (3) play dates in the spring. Please consider this when looking <strong>for</strong> work in the spring.<br />
You will be signing up <strong>for</strong> summer classes as well. You may be invited to work at our<br />
youth summer soccer camp. The soccer program at <strong>Ohlone</strong> is year around. You may not<br />
participate on other club teams during the fall or winter/spring semesters.<br />
Please see specific in<strong>for</strong>mation <strong>for</strong> your class:<br />
FRESHMEN<br />
You will need to make sure you are signed up <strong>for</strong> all classes pertaining to soccer<br />
during the year. Details of these classes will be made available on our team web page.<br />
You should know that as an athlete at <strong>Ohlone</strong> you are given first opportunity to register<br />
<strong>for</strong> classes. Take advantage of this. You should already be considering your next college

challenge, we ask that you talk to us about your soccer plans at a four year school and<br />
already be preparing <strong>for</strong> that by making contact with those coaches. Keep in mind you<br />
must have completed 24 units to play again as a sophomore next year. Keep track of your<br />
classes. Freshmen will be assessed during the first week of CAMP. It is possible, if we<br />
deem that you to need more development, you many be RED SHIRTED, which<br />
effectively means you will train, but not play in games, this will preserve a year of soccer<br />
<strong>for</strong> your college future. Also, if you get injured it may still be possible to RED SHIRT<br />
you depending upon the circumstances. Please see the athletic counselor with any<br />
questions.<br />
SOPHOMORES<br />
You should already have a plan <strong>for</strong> your four-year school if you plan on going.<br />

have us contact coaches <strong>for</strong> you. Keep in mind that your grades need to be strong to<br />
move on. Also, keep in mind that you must have 24 units under your belt if you intend<br />
to play this year. RED SHIRTING is also a possibility <strong>for</strong> sophomores.<br />
TRANSFER STUDENTS<br />
Transfer students coming from another school must complete the appropriate <strong>for</strong>ms<br />
with the athletic counselor. If you are coming from a school and have not played<br />
previously in college soccer this should be very straight-<strong>for</strong>ward. If you are coming from<br />
another school and have played, you will need to obtain at least 12 units at <strong>Ohlone</strong><br />
<strong>College</strong> and or have successfully achieved at least 24 units since the start of your first<br />

Quick Facts...<br />
• Athletes achieve peak per<strong>for</strong>mance by training and eating a variety of foods.<br />
• Athletes gain most from the amount of carbohydrates stored in the body.<br />
• Fat also provides body fuel; use of fat as fuel depends on the duration of the<br />
exercise and the condition of the athlete.<br />
• Exercise may increase the athlete's need <strong>for</strong> protein.<br />
• Water is a critical nutrient <strong>for</strong> athletes. Dehydration can cause muscle cramping<br />
and fatigue.<br />

ABSTRACT<br />
Purpose. Muscle post-activation potentiation (PAP) is a mechanism by which power twitch is increased after previous<br />
conditioning contractions. In this study, we determined the time-dependent effect of a loaded drop-jump protocol on<br />
sprint time and countermovement jump height in well-trained athletes. Methods. Ten athletes randomly per<strong>for</strong>med the<br />
control and experimental protocols on two different days. As a pre-test, the athletes per<strong>for</strong>med the vertical jump and 50 m<br />
sprint test <strong>for</strong> preload measurements. Then, the experimental or control protocol was randomly applied, where the control<br />
protocol was composed of the athletes remaining at rest <strong>for</strong> 10 min. In the experimental protocol, the athletes per<strong>for</strong>med<br />
two sets of 5 drop jumps (0.75 m), with a 15 s interval between the jumps and a 3 min rest after each set. Then<br />
the vertical jump and 50 m sprint tests were per<strong>for</strong>med again 5, 10, and 15 min after the protocol. Results. The experimental<br />
condition (drop jump potentiation protocol) increased per<strong>for</strong>mance in the vertical jump by 6% after 15 min<br />
(p < 0,01) and in the sprint by 2,4% and 2,7% after 10 and 15 min, respectively (p < 0,05). Conclusions. These findings<br />
suggest that the drop jump potentiation protocol increases countermovement vertical jump and sprint per<strong>for</strong>mance in<br />
high-per<strong>for</strong>mance athletes at different times, suggesting that PAP induction depends not only on the design of the protocol,<br />
but also on the effect of time and the type of exercise involved.<br />
Key words: muscle post-activation potentiation, sprint, vertical jump, drop jump, per<strong>for</strong>mance<br />
Introduction<br />
Tbe development of muscle power output is a determinant<br />
of sport per<strong>for</strong>mance, especially in track and<br />
field events that are composed of running short distances<br />
or vertical and horizontal jumps [1, 2]. Several<br />
training techniques <strong>for</strong> maximizing muscle power<br />
have been investigated in order to acutely improve<br />
sport per<strong>for</strong>mance, but the results found in literature<br />
are not conclusive [1],<br />
Per<strong>for</strong>mance in sprint running is dependent on the<br />
ability to generate high velocity in a short time interval,<br />
which itself depends on numerous biomechanical,<br />
architectural and biochemical factors [3], Various<br />
training approaches are commonly used to improve<br />
sprint per<strong>for</strong>mance, including sprint drills, overspeed<br />
training, strength training and plyometrics [4, 5], Mero<br />
and Komi [6] suggested that the elastic properties of<br />
the muscles and their energy stores are necessary <strong>for</strong><br />

high per<strong>for</strong>mance in sprint events. This fact supports<br />
the importance of power training to develop sprint potential.<br />
Plyometrics is a training method tbat develops<br />
the ability of muscles to produce <strong>for</strong>ce at high speeds<br />
(power output) in dynamic movements. This training<br />
is composed of muscle stretch followed by an explosive<br />
concentric contraction, known as the stretch-shorten<br />
cycle (SSC) [7]. Kotzamanidis [5] found that 10 weeks of<br />
plyometric training improved jump ability and running<br />
velocity in prepubescent boys. Similarly, Rim mer and<br />
Sleivert [8] reported a significant increase in sprint per<strong>for</strong>mance<br />
following sprint-specific plyometric training<br />
<strong>for</strong> eight weeks in male participants who had no experience<br />
with tbis kind of training.<br />
In regards to acute power enhancement, several<br />
studies suggest that per<strong>for</strong>mance is increased after<br />
different protocols of muscle potentiation [9, 10]. This<br />
increase of acute power output has been related to post-<br />
-activation potentiation (PAP) [11, 12], PAP is a mecbanism<br />
by which muscle contractile ability is increased<br />
by a previous bout of maximal or submaximal contractions<br />
[1, 13]. Tbe precise mechanisms involved in<br />
PAP activation still remain unclear. Some theories<br />

HUMAN MOVEMENT<br />
J.C.B. Lima et al.. Muscle post-activation and per<strong>for</strong>mance<br />
bave been suggested, sucb as an increase of phosphórylation<br />
in the light chains of myosin, which elevates<br />
the sensitivity of actin-myosin interaction to release<br />
Ca^"^ from the sarcoplasmatic reticulum [13, 14], the<br />
modification of reflex activity in the spinal cord<br />
(H-reflex) [15], and the recruitment of a high number<br />
of motor units [1]. Previous studies have demonstrated<br />
that the manifestation of PAP depends on muscle<br />
characteristics, such as trairiing status (particularly<br />
strength levels) [16], the distribution of fiber type [17],<br />
tbe contractile conditions (whether shortening or<br />
lengthening) [18], as well as an individual's training<br />
background (greater PAP in power atbletes when compared<br />
to endurance athletes) [19].<br />
Several potentiation protocols have investigated<br />
the effects of maximal and submaximal muscle activity<br />
on subsequent athletic per<strong>for</strong>mance [11, 20]. Traditionally,<br />
PAP has been induced by an application of<br />
a strength training stimuli (preload), such as a heavyload<br />
squaf [11, 21] and maximal voluntary isometric<br />
contraction [19]. Masamoto et al. [22] observed tbat<br />
one repetition maximum (lRM) per<strong>for</strong>mance was increased<br />
(by 3.5%) in trained atbletes wben executed<br />
30 s after one set of two depth jumps. Young et al. [10]<br />
reported that a single set of 5 maximal repetitions of<br />
squats increased counter movement jump height (by<br />
2.8%) when per<strong>for</strong>med 4 min later in athletes experienced<br />
with squat exercise. Kilduff et al. [23] also<br />
found an improvement in countermovement jump<br />
per<strong>for</strong>mance (by 4.9%), determined after 8 min (post<br />
8 min) of squat potentiation^ protocol (tbree sets of<br />
3 repetitions at 87% lRM). Weber et al. [24] found an<br />
enbanced peak beigbt of squat jump (by 4.7%) when<br />
completed 3 min after one set of 5 repetitions of back<br />
squat jumps at 85% of 1 RM m track and field atbletes.<br />
Smith et al. [10] reported an increase in power output<br />
in a 10 s sprint cycle test when per<strong>for</strong>med 5 min after<br />
ten sets of 1 repetition of parallel back squats at 90%<br />
lRM. McBride et al. [21] observed an improvement in<br />
40 m sprint time (by 0.87%) in football players after 4<br />
min of doing one set of 3 repetitions of beavy-loaded<br />
squats at 90% of lRM. Chatzo'poulos et al. [25] showed<br />
that 10 repetitions of heavy resistance stimulus at 90%<br />
of lRM was able to improve running speed in tbe 10<br />
and 30 m dasb in amateur players of team games when<br />
executed 5 min later.<br />
Although several potentiation protocols have demonstrated<br />
an improvement in sport per<strong>for</strong>mance, some<br />
studies did not find any effe¡ct. Scott and Docherty<br />
[20] observed that one set of 5 maximal repetitions of<br />
back squats has no effect on maximal jump height and<br />
distance measured 5 min later in resistance-trained<br />
men. McBride et al. [21] related that one set of 3 repetitions<br />
of loaded-countermovement jumps (CMJ) does<br />
not improve per<strong>for</strong>mance in the 40 m sprint when<br />
per<strong>for</strong>med 4 min later. Hanson et al. [26] demonstrated<br />
that a single squat per<strong>for</strong>med at 80% of lRM does not<br />
improve vertical jumping per<strong>for</strong>mance when measured<br />
immediately after tbe potentiation protocol in resistance-trained<br />
athletes. Parry et al. [13] observed that 5<br />
back squats at 90% of IRM bave no effect on maximal<br />
cycle ergometer per<strong>for</strong>mance wben executed 20 min<br />
later in male rugby players. Moreover, Lloyd and Deutscb<br />
[27] did not observe any effect on sprint per<strong>for</strong>mance<br />
after a 3-repetition maximum squat (post-10 min) and<br />
sbowed an impairment in 5 m split and 20 m sprint<br />
times (post-10 min) by tbe countermovement jump<br />
potentiation protocol.<br />
Tbus, several metbods to induce PAP have been<br />
suggested and studied in order to improve output power<br />
per<strong>for</strong>mance. However, it is difficult to compare tbe<br />
results as there are several factors involved in PAP induction,<br />
such as protocol design, maximal induction<br />
time, sport modality, fiber type distribution, contractile<br />
conditions as well as an individual's training background.<br />
Data available in literature on muscle PAP<br />
protocols and output power per<strong>for</strong>mance are not yet<br />
conclusive. Moreover, PAP induction at different times<br />
by tbe same experimental protocol in two different<br />
bigh power exercises has also not yet been investigated.<br />
Tbere<strong>for</strong>e, in tbis study we propose to evaluate tbe<br />
acute effects of one potentiation protocol (two sets of<br />
5 tepetitions of drop jumps) at different times (at preload<br />
and post 5, 10 and 15 min) on tbe per<strong>for</strong>mance<br />
of two bigb power exercises (tbe sprint time in tbe 50 m<br />
dasb and countermovement jump [CMJ] beigbt) in<br />
track and field atbletes wbo have bad at least 6 years<br />
of training experience in order to avoid any possible<br />
adaptation effects to the training protocol. This study<br />
was conducted as a randomized cross-over trial, where<br />
all participants per<strong>for</strong>med the control and experimental<br />
protocols on two different days.<br />
Material and methods<br />
Ten male athletes were selected among the sprinters<br />
that represented the city of Guarulhos, Brazil in official<br />
track and field competitions. The participants were<br />
high-level professional athletes, regularly involved in<br />
jumping, sprint, stretching and power training activities<br />
and were experienced in botb training and competition<br />
<strong>for</strong> at least six years. Tbe age, body mass, and<br />
beigbt of tbe group was: 20.6 ±2.6 years; 73.7 ± 9.22 kg;<br />
and 176.4 ± 5.81 cm, respectively. Be<strong>for</strong>e involvement<br />
in tbe study, tbe atbletes were in<strong>for</strong>med about the objectives<br />
and metbods of tbe study and signed a voluntary<br />
consent <strong>for</strong>m. Tbe athletes were instructed and<br />
accompanied at all times by a professional pbysical<br />
trainer in order to ensure that all of tbe procedures<br />
and techniques used in this study were per<strong>for</strong>med correctly.<br />
This study was approved by tbe Researcb Etbics<br />
Committee from Cruzeiro do Sul University, Sao Paulo,<br />
Brazil (165/2008).<br />
All of tbe participants randomly per<strong>for</strong>med botb<br />

the control and experimental protocols during two<br />
visits with 72 h rest between them in order to eliminate<br />
any possible crossover effects from the previous<br />
test. In addition, 24 h rest was given be<strong>for</strong>e the first<br />
day of testing. Just be<strong>for</strong>e each of the protocols, the<br />
athletes were submitted to a standardized warm-up<br />
(consisting of aerobic and stretching exercises).<br />
Figure 1 illustrates the protocol conditions used in<br />
this study. Each protocol condition was per<strong>for</strong>med on<br />
a different day. The control condition was composed<br />
of a standardized warm up, followed by 5 min rest.<br />
For pre-test measurements, the participants' countermovement<br />
jump (CMJ) and 50 m sprint results were<br />
determined. After the pre-test, the athletes had 5 min<br />
of rest and remained resting <strong>for</strong> an additional 5 min<br />
(as part of the control condition). Then they subsequently<br />
per<strong>for</strong>med the CMJ and the 50 m sprint test<br />
again at intervals of 5 min, 10 min and 15 min after<br />
the control condition (rest).<br />
The experimental condition was composed of<br />
a standardized warm up, followed by 5 min rest and<br />
then the CMJ and 50 m sprint test (<strong>for</strong> pre-test measurements).<br />
After the pre-test and 5 min rest, the athletes<br />
per<strong>for</strong>med a drop jump (DJ) potentiation protocol<br />
composed of two sets of 5 drop jumps at a height<br />
of 0.75 m and were instructed to react as fast as they<br />
could to immediately execute a vertical jump. Two<br />
sets of 5 drop jumps were per<strong>for</strong>med with 15 s rest<br />
between the jumps and 3 min rest between the sets.<br />
Finally, after the drop jump sets, the athletes subsequently<br />
per<strong>for</strong>med the CMJ and 50 m sprint test 5,10,<br />
and 15 min after the DJ potentiation protocol.<br />

Figure 1. Experimental design of the study<br />
The CMJ test was per<strong>for</strong>med with an initial movement<br />
that began with an extended leg position with<br />
the trunk in the upright position and the hands placed<br />
at the hips. The athletes then per<strong>for</strong>med an excentricconcentric<br />
action that finished with a vertical jump.<br />
An electronic contact mat plat<strong>for</strong>m system (Multisprint,<br />
Hidrofit, Brazil) was connected to a computer<br />
that was used to measure the vertical jump height<br />
based on flight-time [28].<br />
The 50 m sprint time was assessed at an outdoor<br />
track, where an infrared timing system (Multisprint,<br />
Hidrofit, Brazil) with 0.001 s accuracy was used. The<br />
sensors were positioned at 0 m and 50 m of the track<br />
to record the beginning and end of the race. The participants<br />
started each sprint from a three-point stand<br />
position and were instructed to accelerate and run as<br />
fast as possible. Wind speed was monitored throughout<br />
the entire experiment using a digital portable anemometer<br />
(AD-250, Instrutherm, Brazil). All the procedures<br />
were per<strong>for</strong>med at the same time of day and the<br />
maximum wind speed limit adopted <strong>for</strong> the experiments<br />
was 2.0 m/s, the same bencbmark adopted by<br />
the IAAF during official outdoor sporting events.<br />
The results were analyzed using statistical software<br />
(GraphPad Prism 5®, San Diego, USA). First, the data<br />
were submitted to the Shapiro-Wilcox normality test<br />
and then analyzed by one-way ANOVA witb repeated<br />
measures followed by Tukey's multiple comparison<br />
post-hoc test. Data were considered significant when<br />
p was < 0.05.<br />
Results<br />
The obtained sprint results <strong>for</strong> botb the experimental<br />
and control conditions are presented in Table 1<br />
(individual values) and Figure 2 (as mean + standard<br />
error of the mean [SEM]). There was a significant difference<br />
in tbe 50 m dash time between the experimental<br />
and control conditions at the post-10 and post-15<br />
min intervals (6.361 ± 0.23 s vs. 6.516 ± 0.24 s and<br />
6.299 ± 0.24 s vs 6.468 ± 0.25 s) of -2.4% and -2.7%<br />
(p < 0.05), respectively. In addition, a significant reduction<br />
in the 50 m sprint time was observed in the experimental<br />
condition at post-10 and post-15 min by -1.4%<br />
and by -2.4% (p < 0.05), respectively, when compared<br />
to the pre-test (6.452 + 0.23 s vs 6.361 ± 0.23 s and<br />
6.452 ± 0.23 s vs 6.299 ± 0.24 s) (p < 0.01). Sprint time<br />
was also decreased in the experimental condition at<br />
post-15 min by -1.8% (p < 0.01) when compared to<br />
the post-5 min interval (6.299 ± 0.08 s vs 6.415 ± 0.07 s).<br />
The results of tbe CMJ height <strong>for</strong> the experimental<br />
and control conditions are presented in Table 2 (individual<br />
values) and Figure 3 (mean + SEM). Similarly to<br />
sprint per<strong>for</strong>mance, the experimental protocol led to<br />
a significant increase in CMJ height at post-15 min by<br />
+5.5% (45.8 ± 0.66 cm vs 43.4 ± 0.86 cm; p < 0.01)<br />
when compared to control condition. In addition, the<br />

Discussion<br />
Muscle PAP is a mechanism by which power twitch<br />
is increased after previous conditioning contractions<br />
[1, 12, 13]. Since there are various factors involved in<br />
PAP induction and since the time of maximal induction<br />
has not yet been investigated, this study evaluated<br />
tbe effects of a DJ potentiation protocol on sprint time<br />
and CMJ beight per<strong>for</strong>mance in well-trained athletes<br />
at different times. It was found that the DJ potentiation<br />
protocol was effective in inducing PAP and improving<br />
per<strong>for</strong>mance in both the 50 m dash and vertical jump.<br />
Sprint time decreased after 10 and 15 min and CMJ<br />
height increased after 15 min in the experimental<br />
condition (DJ potentiation protocol), suggesting that<br />
the time <strong>for</strong> maximal PAP induction is specific <strong>for</strong> different<br />
high power exercises.<br />
As previously mentioned, strength-exercise induced<br />
PAP has been sbown to be effective in considerably<br />
increasing CMJ height. Young et al. [10] observed an<br />
improvement in loaded-CMJ height of 2.8% in athletes<br />
4 min after per<strong>for</strong>ming one set of 5 maximal repetitions<br />
of squats. Our DJ potentiation protocol induced<br />
an increase in CMJ height only at post-15 min. We<br />
believe that the difference is due to the design of the<br />
experiment. In tbe Young et al. [10] study, the athletes<br />
executed two sets of 5 loaded CMJ (as pre-load), followed<br />
by tbe squat exercise potentiation protocol and<br />
finally by one set of 5 loaded-CMJ (post-load). An interval<br />
of 4 min between the sets was imposed and the<br />
results were compared between pre- and post-load.<br />
Thus, PAP induction of this protocol could have resulted<br />
from all of the per<strong>for</strong>med exercise and not only<br />
from the squat exercise protocol. In fact, the total<br />
time between the first pre-load test and post-load test<br />
in the Young et al.'s [10] study was 16 min.<br />
As previously discussed, not only is the time interval<br />
an important factor <strong>for</strong> maximal PAP manifestation,<br />
but also other factors which are involved in tbis<br />
process. These factors include the design of the potentiation<br />
protocol, the type of high power exercise and<br />
tbe experience of the athletes. It is difficult to compare<br />
our study to others as tbese factors vary greatly.<br />
PAP manifestation is observed at different time intervals<br />
after the potentiation protocols' application in<br />
several studies. These post-load time intervals vary<br />
between 0.5 min and 20 min [10, 11, 23]. Thus, all<br />
these factors need to be considered when potentiation<br />
programs are used by athletes that intend to increase<br />
muscle power output.<br />
A limited number of studies have investigated the<br />
effects of PAP manifestation on sprint time and running<br />
speed. When compared to other studies, our DJ potentiation<br />
protocol improved sprint time only at tbe post-<br />
10 min and post-15 min intervals. Some studies have<br />
found no effect of different potentiation protocols on<br />
sprint per<strong>for</strong>mance when the individuals were evaluated<br />
after a short time of the application (few minutes).<br />
Cbatzopoulos et al. [25] found that a back half-squat<br />
potentiation protocol (10 single repetitions at 90% of<br />
lRM) did not increase running speed post-3 min in<br />
a 30 m dash. McBride et al. [21] found that a loaded-<br />
CMJ protocol (one set of 3 repetitions) did not improve<br />
sprint time post-4 min in a 40 m dash. After the PAP<br />
protocols, both potentiation and fatigue could coexist<br />
and the balance between these two factors are determinants<br />
in the final per<strong>for</strong>mance of subsequent high<br />
power exercise [1, 26]. Previous studies have shown<br />
that a period of 4-5 min is required to restore creatine<br />
phosphate and the effectiveness of PAP can be found<br />
up to 20 min [10]. Tbere<strong>for</strong>e, in our study, the effect<br />
of fatigue may have a negative effect on PAP at 5 min<br />
after the DJ potentiation protocol.<br />
However, McBride et al. [21] observed an improvement<br />
in 40 m sprint time (0.87%) in football players<br />
after 4 min of applying one set of 3 repetitions of<br />
heavy-loaded squat at 90% of IRM, but no effect was<br />
found when the athletes were submitted to a loaded-<br />
CMJ protocol (one set of 3 repetitions) in the same<br />
study, demonstrating that the potentiation protocol<br />
design is an important factor <strong>for</strong> PAP manifestation.<br />
In our study, we found a decrease (non-significant) of<br />
0.50% in sprint time by DJ potentiation protocol at<br />
the post-5 min interval when compared to the pre-test.<br />
At post-10 min and post-15 min, the reduction amounted<br />
to 1.4% and 2.4%, respectively. As discussed above<br />
and observed in our study, the post-load time interval<br />
was an important factor <strong>for</strong> PAP induction. Thus, it is<br />
possible that the improvement found by McBride et al.<br />
¡21] would be higher if the time interval was more<br />
prolonged. Moreover, the effect of fatigue can be more<br />
pronounced in our design potentiation protocol than<br />
in the protocol used by McBride et al. [21].<br />
Conclusion<br />
The results obtained in this study suggest that muscle<br />
PAP programs are useful in increasing per<strong>for</strong>mance in<br />
high power exercises. However, several factors are involved<br />
in this process and need to be considered when<br />
these programs are used <strong>for</strong> training track and field<br />
athletes. These factors include the design of the potentiation<br />
protocol, the time required <strong>for</strong> maximal induction,<br />
the type of high power exercise and the experience<br />
of the athletes. The potentiation protocol used in<br />
this study (two sets of 5 DJ) is an acute power training<br />
method that can be used by coacbes and physical<br />
328
:-*v- -rU- I<br />
trainers in order to improve an athlete's speed in short<br />
distances and their per<strong>for</strong>mance in vertical jumps when<br />
competing. This protocol induced an improvement in<br />
50 m sprint time after 10 min and 15 min and in<br />
a countermovement vertical jitmp after 15 min, demonstrating<br />
that the post-load time interval <strong>for</strong> increasing<br />
per<strong>for</strong>mance by DJ potentiation protocol in track and<br />
field experienced athletes varies according to tbe type<br />
of high power exercise involved. Additional studies<br />
are required to evaluate if different DJ potentiation<br />
protocols (e.g, different heights of tbe box <strong>for</strong> tbe DJ<br />
or the number of sets and drop jumps per set) can be<br />
more efficient <strong>for</strong> improving per<strong>for</strong>mance in sprint<br />
and CMJ.<br />
In summary, our results suggest tbat the DJ potentiation<br />
protocol used in this study improves per<strong>for</strong>mance<br />
in sprint time and vertical jump in high per<strong>for</strong>mance<br />
athletes at different times, suggesting that the<br />
peak of PAP induction depertds not only on protocol<br />
design, but also on the post-loaded time and the high<br />
power exercise.<br />

ABSTRACT<br />
Aim: The purpose of this study was to compare<br />
static and dynamic warm-up regimes on lower<br />
limb muscle power and thereby the per<strong>for</strong>mance<br />
of the individual. Methodology: Twenty<br />
eight (28) subjects were assigned into groups<br />
consisting of 2 members. From each group, 1<br />
subject per<strong>for</strong>med the static stretching and the<br />
other subject per<strong>for</strong>med dynamic stretching as<br />
warm-up. This was followed by non-counter<br />
movement jumps on a <strong>for</strong>ce plat<strong>for</strong>m and the<br />
vertical jump heights were recorded. Data were<br />
analysed using one-way ANOVA and paired<br />
t-test at 0.05 alpha. Result: The results showed<br />
that dynamic stretching as warm-up causes<br />
significant increase (p=0.01) in the vertical jump<br />
height as compared to static stretching (p=0.03).<br />
Discussion: The increase in vertical jump height<br />
could be related to the increase in <strong>for</strong>ce production<br />
which plays an important role during<br />
the vertical jump test. On the other hand the<br />
decrease in vertical jump height following static<br />
stretching could be attributed to a decrease in<br />
the <strong>for</strong>ce production in the muscles. Conclusion:<br />
Dynamic warm-up increases the vertical lump<br />
height, whereas static stretching decreases the<br />
jump height of the athlete.<br />

1. INTRODUCTION<br />
The primary aim of exercise physiologists, personal<br />
trainers, bio-mechanical engineers and sports scientists<br />
is to monitor and increase the per<strong>for</strong>mance levels of the<br />
athletes under their training. When it comes to training<br />
and prescribing exercises, there is always a debate between<br />
the types of stretching that are being used as warm<br />
up be<strong>for</strong>e activity. This could also be used to check the<br />
per<strong>for</strong>mance of the athlete owing to the particular type<br />
of stretching.<br />
Static stretching involves holding the muscle in the<br />
stretched position <strong>for</strong> some time. This type of stretching<br />
has been used as a traditional method of warm up as well<br />
as per<strong>for</strong>mance enhancement <strong>for</strong> quite some time now.<br />
But research per<strong>for</strong>med by Rosenbaum and Hennig<br />
(1995) [1], shows that static stretching decreases peak<br />
<strong>for</strong>ce by 5% and rate of <strong>for</strong>ce production by 8%, there by<br />
actually decreasing muscle strength. Static stretching of<br />
calf, hamstrings and quadriceps reduces the peak vertical<br />
velocity of a vertical jump according to studies done by<br />
Knudson et al., 2000 [2]. Studies done by Kokkonen et<br />
al., 1998 [3], have documented a rather harmful effect of<br />
acute static stretching, that it actually decreases the per<strong>for</strong>mance<br />
of those tasks where success is related to<br />
maximal <strong>for</strong>ce development. Further studies by McNeal<br />
and Sands, 2003 [4], with younger populations have also<br />
illustrated impairment in jumping per<strong>for</strong>mance in teenagers<br />
following static stretching.<br />
Dynamic stretching consists of functional based exercises<br />
which use sport specific movements to prepare the<br />
body <strong>for</strong> movement. It consists of controlled leg and arm<br />
swings that are taken gently to the limits of range of motion.<br />
Studies done by Fredrick G. A., 2000 [5] have<br />
shown the effectiveness of dynamic stretching, as this<br />
increases core temperature, muscle temperature, elongates<br />
the muscles and stimulates the nervous system,<br />
thereby decreasing the chances of injury. Faigenbaum et<br />
al., 2005 [6] studied dynamic warm-up versus static<br />
stretching in different age groups and a variety of athletes.<br />
And found that compared to static stretching, dynamic<br />
warm up increases flexibility and also improved<br />
per<strong>for</strong>mances among children <strong>for</strong> vertical jump. Longjump<br />
per<strong>for</strong>mance also improved in the dynamic warmup.<br />
Studies by Duncan M. J. and Woodfield L. A., 2006<br />
[7] suggest that there may be some advantage to per<strong>for</strong>ming<br />
a low to moderate dynamic warm up protocol<br />
prior to activities that require high power outputs.<br />
The purpose of this study is to find out which type of<br />
stretching exercise used as warm-up affects lower limb<br />
muscle power and there<strong>for</strong>e affects per<strong>for</strong>mance of an<br />
individual.<br />

2. METHODOLOGY<br />
J. Shelton et al. / HEALTH 1 (2009) 117-120<br />
at 0.05 alpha.<br />
2.1. Subjects<br />
Twenty eight moderately trained subjects (16 male and<br />
12 female) ranging in the age group of 20 to 35 years<br />
were taken <strong>for</strong> the study. They were randomly divided<br />
into groups consisting of 2 members. From each group,<br />
one subject per<strong>for</strong>med the static stretching and the other<br />
subject per<strong>for</strong>med the dynamic stretching as part of the<br />
warm up.<br />
2.2. Procedure of Data Collection:<br />
Baseline Measurement<br />
Both the groups per<strong>for</strong>med an initial non-counter<br />
movement jump with both hands on the hips on a <strong>for</strong>ce<br />
plat<strong>for</strong>m and the vertical jump height was recorded.<br />
The subjects in both the groups were made to jog 12<br />
laps (up to 60% VO 2 max) up and down in the corridor<br />
after which the heart rate (Carotid artery) was recorded.<br />
Then they per<strong>for</strong>med the first non-counter movement<br />
jump on the <strong>for</strong>ce plat<strong>for</strong>m and the vertical jump heights<br />
were recorded.<br />
2.3. Stretching Protocol<br />
The static stretching group subjects actively per<strong>for</strong>med<br />
some static calf, hamstrings, quads, gluteal and hip<br />
flexor stretching exercises <strong>for</strong> 2 repetitions 30 seconds<br />
each, <strong>for</strong> both the legs.<br />
While the dynamic stretching group subjects per<strong>for</strong>med<br />
some dynamic stretching exercises like tip-toe<br />
walking, <strong>for</strong>ward and backward leg swings, sagittal<br />
plane leg swings, walking knee pull ups, walking lunges<br />
with hip rotation and walking quads stretches <strong>for</strong> 2x10<br />
repetitions <strong>for</strong> both legs.<br />
2.4. Post Stretch Measurement<br />
Then the second heart rate (Carotid artery) was recorded<br />
<strong>for</strong> both the groups. After which they per<strong>for</strong>med the<br />
second non-counter movement jump on the <strong>for</strong>ce plat<strong>for</strong>m<br />
and the vertical jump heights were recorded. Then<br />
the subjects were asked to remain standing, without doing<br />
any activity <strong>for</strong> 10 minutes. Then they per<strong>for</strong>med the<br />
third and final non-counter movement jump on the <strong>for</strong>ce<br />
plat<strong>for</strong>m and the vertical jump heights were recorded.<br />
Finally the vertical jump heights and heart rate readings<br />
<strong>for</strong> both the static and dynamic groups were recorded.<br />
2.5. Data Analysis<br />
Descriptive statistics of range, mean and standard deviation<br />
were computed on all data. One way ANOVA was<br />
calculated across the recording of both the groups. A<br />
paired t-test was computed to compare the static and<br />
dynamic stretching groups. Level of significance was set<br />
3. RESULTS<br />
The mean and standard deviation of the jump heights of<br />
the subjects in both the static and dynamic stretching<br />
groups are shown in Tables 1 and 2.<br />
The static stretching group showed a decrease of<br />
0.61% in the final jump as compared to the dynamic<br />

as shown in Figures 1 and 2.<br />
4. DISCUSSION<br />
As the result shows dynamic warm up can definitely<br />
increase the vertical jump height and there<strong>for</strong>e significantly<br />
influences fitness per<strong>for</strong>mance, as compared to<br />
the group that did static stretching as warm up. These<br />
findings are similar to the studies done by Duncan and<br />
Woodfield 2006 [7] and Faigenbaum et al., 2005 [6]<br />
which show that dynamic stretching increases flexibility<br />
as well as muscle power.<br />
Among the subjects who did static stretching, from<br />
Figure 3, we can see that there is a decrease in jump<br />
height between the first and second jumps. This shows<br />
that static stretching might actually reduce <strong>for</strong>ce production,<br />
which is similar to the studies done by Rosenbaum<br />
and Hennig, 1995 [1]. The main muscles involved in a<br />
vertical jump are the calf, quadriceps and hamstrings.<br />
These muscles were part of the static stretching protocol<br />
of the warm up. On the other hand, we can see an increase<br />
in the vertical jump height between second and<br />
third jumps, this change could be because of the ten<br />
minutes rest period in between the jumps. And this rest<br />
period would have given time <strong>for</strong> the muscles to recover<br />
after the period of static stretching. This implies that<br />
static stretching actually causes a decrease in the <strong>for</strong>ce<br />
production in these muscles as also shown in the studies<br />
by Kokkonen et al., 1998 [3] and Knudson et al., 2000<br />
[2]. There<strong>for</strong>e the per<strong>for</strong>mance of the activity (vertical<br />
jump height) is also decreased as a result of static<br />
stretching which is also similar to the studies done by<br />
McNeal J. and Sands W., 2003 [4]. The reason <strong>for</strong> this<br />
decrease in per<strong>for</strong>mance could be attributed to an increase<br />
in the musculo-tendinous unit (MTU) compliance,<br />
leading to a decrease in the MTU ability to store elastic<br />
energy in its eccentric phase as reported by Fletcher IM,<br />
Jones B, 2004 [8]. The above evidences suggest that<br />
static stretching prior to activity is not the best solution.<br />
Static stretching does not necessarily lead to a decrease in<br />
injury but may actually decrease the <strong>for</strong>ce production and<br />
thereby decrease the vertical jump height <strong>for</strong> the athlete.<br />
On the other hand we can see from Figure 4, there is<br />
a significant increase in the vertical jump height in the<br />
group that did dynamic stretching as part of the warm up,<br />
which is similar to studies done by Faigenbaum et al,<br />
2005 [6]. Studies by Duncan and Woodfield, 2006 [7]<br />
have suggested that per<strong>for</strong>ming pre-event dynamic warm<br />
up protocols may create an optimal environment <strong>for</strong> ex-<br />

plosive <strong>for</strong>ce production by enhancing neuromuscular<br />
function. This occurrence has been termed the ‘postactivation<br />
potentiation’ (PAP) [9] and is believed to increase<br />
the rate of <strong>for</strong>ce development, thereby increasing<br />
speed and power production. This finding was similar to<br />
the study done by Faigenbaum et al., 2005 [6]. Dynamic<br />
warm up activities used in the study may have influenced<br />
the excitability of fast twitch motor units and<br />
there<strong>for</strong>e readied these units to play a more significant<br />
role during the vertical jump test. However no tests of<br />
neuromuscular activation were per<strong>for</strong>med in this study.<br />
Neuromuscular activation studies can be done in future<br />
to measure the excitability of fast twitch motor units.<br />
The results of the current study suggest that there may be<br />
some advantage to per<strong>for</strong>ming a low to moderate dynamic<br />
warm up protocol prior to activities that require<br />
high power outputs. And the increase in vertical jump<br />
height following dynamic warm up compared to static<br />
warm up is considerable.<br />
Faigenbaum et al. 2005 [6] in his study also says that<br />
the evidence supporting the injury-reducing and per<strong>for</strong>mance-enhancing<br />
potential of static stretching is<br />
presently lacking. So it may be desirable to per<strong>for</strong>m dynamic<br />
stretching during the warm up period and static<br />
stretching during the cool down. The purpose of warm<br />
up exercise is to warm-up the body, but static stretching<br />
seems to cause cool down of the body.<br />
5. CONCLUSIONS<br />
From the above study it can be concluded that the effect<br />
of dynamic stretching as warm up has the following<br />
benefits. Dynamic Stretching increase <strong>for</strong>ce production<br />
prior to activity, which in turn can improve the vertical<br />
jump height of the athlete.<br />
As exercise physiologists and sports scientists our<br />
main objective is to decrease the injury levels and increase<br />
the per<strong>for</strong>mance levels of the athletes. And the<br />
above evidences from related literature suggest that dynamic<br />
stretching is the best type of stretching that can be<br />
per<strong>for</strong>med during warm-up in order to increase the jump<br />
height of the athlete and to increase per<strong>for</strong>mance levels<br />
of the athlete. From the findings of the study in order to<br />
increase the vertical jump height of the athlete we can<br />
recommend a sports per<strong>for</strong>mance program that includes<br />
dynamic activities during warm up and static stretching<br />
as part of the cool down.<br />
