APPROACH RUN AND ACCELERATION PATTERNS 14 techniques AUGUST 2011
a pole relative to their top speed. Much of this difference is likely due to pole size more so than to carry efficiency but that was not tested. These willing athletes exhibited a wide range of abilities. All of them did have experience with none being raw beginners (no experience). Those with more experience and with greater performances (higher vaults to their credit) tended to run faster and had a more even acceleration curve. An example is provided in Tables 3 and 4 with their corresponding graphs. Comparing these two athletes, one was a high school intermediate and the other a skilled high school athlete (in fact, one of the top high school athletes attending the clinic). This may suggest that it is a skill to develop an approach that can smoothly and effectively bring an athlete to top speed, or put another way, bring an athlete to useable top speed. Observing all the data, it seems that just running from further back is not likely the key factor in bringing out the athlete’s very best. TO SUM UP THE STUDY OF THIS GROUP: These athletes were running at 90 percent of their top speed less than 60 feet into their trial run whether they carried a pole or did not carry a pole. On average, the remaining 10 percent of their top speed required a distance of between 50 and 60 feet, or roughly half the distance required to accelerate to top speed, again whether carrying a pole or not. The boys tended to need a little more distance to hit top speed when carrying a pole whereas the girls tended to need a little less distance. Carrying a pole while running slowed these runners about five percent. An unmeasured observation was that the faster and more experienced athlete took longer (distance run) to reach top speed and tended to have a more regular acceleration curve than the less-experienced and slower athlete. I think these observations are worthy of consideration for the coaching of all jumping events. Of special coaching note is that if an athlete needs more technical preparation in jumping mechanics, taking more trials from an approach of six to 10 steps (three to five lefts) makes good sense. The athlete will, in all likelihood, be able to take more attempts, concentrate jumping technique, and still function near top speed. The process of achieving top speed in a controlled and “smooth or regular” manner also appears to be a skill and therefore needs to be practiced as well. ADDENDUM The Brower timing system was also used in the Friday night elite men’s and women’s competitions. In congruence with existing research model on runway velocity just prior to the take off, photo gates were set up to time the last five meters prior to the take off. Results of each attempt of these elite athletes was recorded and shown to the audience on the display units provided. My sincere thanks to Mark Brower and the Brower Timing System staff for their support of the Reno Pole Vault Summit and this project. AUGUST 2011 techniques 15
