Purpose: The purpose of this study was to examine the effects of static stretching and Evjenth-Hamberg stretching on isokinetic muscle strength of knee flexors and extensors.
Methods: The subjects were composed of eighty healthy males without weight-training experience. ROM of knee joint measured active maximal extension and isokinetic Peak Torque measured $60^{\circ}/sec,\;120^{\circ}/sec$ using an the En-Knee. Three tests(Baseline, 4 weeks, 8 weeks, respectively) was operated to examine change of each variable. Data were analyzed with a $2{\times}3$ analysis of variance ($group{\times}test$) for repeated measures on last factor by SPSS package 10.0. The data analysis revealed muscle strength were dependent on stretching method.
Results: The results were as follows. First, Evjenth-Hamberg stretching(E-HS) was more effective than static stretching(SS) on ROM. Second, Peak Torque of knee flexors and extensors was improved in both methods by each time. but E-HS was more improved than SS.
Conclusion: In conclusion, This study indicates that E-HS is more efficient than SS on muscle strength improvement.
