The effects of graston technique treatment times on sprint performance in collegiate wrestlers.

摘要

Objective: The aim of this study was to provide insight on how treatment times of 5-minutes and 8-minutes of GTRTM affect a 30-yard sprint performance. Interventions: 15 healthy college-aged male wrestlers received two treatments (5-minute and 8-minute) of Graston TechniqueRTM separated by approximately 48 hours. After a 5-minute bike warm-up, participants received GTRTM treatment on both quadriceps muscles. Participants completed a 10-minute active rest followed by a 30-second standing quadriceps stretch, 30 straight leg raises and quadriceps stretch again. Participants then sprinted 3 30-yard sprint tests. Results: Significance was found between the baseline (4.63 +/- 0.18 seconds) and 5-minute GTRTM treatment (4.53 +/- 0.18 seconds) sprint times; t(14)=3.34, p = 0.005. No significance was found between the baseline and the 8-minute GTRTM treatment (4.57 +/- 0.19 seconds) sprint times; t(14)=1.49, p = 0.159. Conclusions: Shorter GTRTM treatments provide a warm-up for the tissue allowing for better tissue function.
