implication for players, coaches and sport scientists. The 5-m multiple shuttle repeat sprint test (5-m RST) adopted by Welsh Rugby Union and modified by the Sport Science Institute of South Africa is used to determine player’s match-related fitness (Boddington, Lambert, Gibson, & Noakes, 2001). The test consists of six 30 seconds repeat sprint bouts, interspersed with 35 seconds rest period. The participants performed 6 repeat shuttles of this protocol with a 35-second rest between bouts. The peak distance (greatest distance covered during a 30s shuttle), total distance (the total distance covered during the 6 x 30s shuttles), delta distance (the difference between the longest and shortest shuttle distance and fatigue index are recorded (Boddington et al., 2001). Factors determining success in the 5-m RST are multifaceted, and performance is best predicted by a combination of factors including body mass, strength and aerobic fitness. To cover a total distance in excess of 750m for the 5-m RST requires good basic speed, the ability to run at a pace and accelerate, and excellent aerobic system for a rapid recovery between runs (Hawley & Burke, 1998). Even though deemed important by rugby researchers, there is limited normative data on rugby players. 2.5 CHANGES IN PHYSICAL FITNESS OF OVER A COMPETITION SEASON Professional athletes perform concurrent physical and technical training throughout the season in an attempt to elicit gains in many physical attributes required for optimal performance (Argus, Gill, Keogh, Hopkins & Beaven, 2009).. Physical fitness can provide a coach and the sport scientist with an objective and reproducible means of assessing an athlete/players training status, physical strengths and performance capabilities (O'Gorman, Hunter, McDonnacha, & Kirwan, 2000). Information gathered from these tests can assist the coaching 40

staff with regards to selection and making appropriate adjustments to an individual’s training program. 2.5.1 Body Composition In team sports such as rugby, hockey and soccer, body composition plays is an important role in individual performance because excess body fat may influence speed, power and endurance. A number of investigations suggest that females participating in team sports report desirable changes in body composition (reduction in percentage body fat or skinfold thickness and or increase in lean muscle mass) during rigorous pre-season conditioning (Astorino, Tam, Rietschel, Johnson & Freedman, 2004; Clark, Reed, Crouse & Armstrong, 2003) primarily due to a high training volume (Burke, Gollan, & Read, 1986). During a competition season, players experience a minimal change in body composition (Granados, et al., 2008) as training emphasis is on tactical preparation for the upcoming match and conditioning sessions are predominately of a high intensity but for a short duration (Burke et al., 1986). 2.5.2 Speed A study by Holmyard and Hazeldine (1993) on international rugby players showed that the greatest improvements in sprint performance occurred during the pre-season and the first half of the competition. No additional studies on professional rugby players were found to support the above findings. This is in contrast to a study done on junior and senior rugby league players whereby there was no significant change in 10m and 40m times after a 14 week preseason training program (Gabbett, 2006). The progressive increase in training volume and 41
