Method: In total, 17 international level judo athletes (11 women and 6 men; age, 20.47 +/- 1.59 years; experience in judo, 11.35 +/- 1.84 years) were recruited for this study. The athletes completed three different SS sessions named low (LV-SS: 3.5 min), moderate (MV-SS: 7 min), and high volumes (HV-SS: 10.5 min), 72 h apart, in a randomized crossover study. Before and after each SS exercise session, hamstring flexibility, RSI and K-leg were evaluated by a sit-and-reach test and a Myotest accelerometric system, respectively. Results: Different volumes of SS exercises improved hamstring flexibility (p < .05); however, no one exercise was superior in improving hamstring flexibility than the other (p > .05). Different volumes of SS exercises neither improved nor reduced RSI and K-leg (p > .05). Conclusion: Judo athletes can use LV-SS, MV-SS, or HV-SS for hamstring flexibility enhancement, and SS exercises can be used as a part of a warm-up session prior to judo training or competition.en10.14198/jhse.2021.164.03info:eu-repo/semantics/openAccessHamstring FlexibilityCombat SportStiffnessStretching ExercisesStretch-Shortening CycleWarm-UpMusculotendinous StiffnessExplosive PerformanceShortening CycleJump PerformanceTimeDurationRangeReliabilityIntensityReview Article164760771N/AWOS:0007027447000032-s2.0-85100195303Q3
