F-15 Free Communication/Slide - Creatine: May 30, 2008 1:00 PM - 2:45 PM ROOM: 106
PURPOSE: Creatine supplementation has been shown to improve certain short duration, high intensity exercises. No prior study had examined this potential in relation to sports climbers. The purpose of this study was to assess whether Creatine Supplementation would improve the performance of sports climbers.
METHODS: 12 subjects all male non-vegetarian and who had climbed Extreme Grade (E1) within one calendar month of testing. Each group were tested using 2 x 5 ascents of a climbing wall, each 5 ascent period separated by 5 minutes recovery time. Subjects were assigned randomly to either Creatine Supplemented group (Cr) or Placebo (Pl) in a double blind crossover manner. Each subject participated in exactly the same test protocol 7 days later after ingesting Cr or Pl. During testing Oxygen consumption and Hr was monitored continuously, lactate measurements were obtained from arterialised (fingertip) samples. Any significant differences P<0.05 were subject to Paired Sample T-Tests.
RESULTS: Creatine supplemented group significantly heavier (P = 0.016), Placebo group were not significantly heavier (P = 0.141). Individual subjects timings improved in exercise period after recovery.
CONCLUSIONS: This study demonstrated that a creatine supplementation of 20g daily for five days may improve individual sports climbers performance after recovery periods although this benefit must be balanced against weight gain.
