, isokinetic strength testing with the Biodex system. 17 They measured concentric and eccentric strength with 60°/s. However, this study was excluded because single-leg strength was assessed, but not double-legged 1RM measurements as in the other studies. In this systematic review and meta-analysis, no

research should look at examining whether incorporating other potential risk factors such as eccentric strength and hamstring-to-quadriceps strength ratio could identify those at risk of sustaining a hamstring injury. Conclusions Poor hamstring flexibility, as determined by the AKE during preseason

the change scores from pretest to posttest ranging between 7% and 27%). 8 Eccentric strength training of the hamstring muscles has been investigated in adult male high-level football players. Beneficial effects on isokinetic hamstring strength and sprint performance (flying 30 m time) as well as a

may have been a mechanism for the impaired performance. In contrast to the increase in low force, landing force was decreased on the days after the soccer match. This could reflect decreased eccentric strength. It is noteworthy that peak changes in low force, landing force, and flight height occurred

This inconsistency may be related to sex difference. Male collegiate athletes were found to have significantly greater hip
