AB Objectives: The aim of this study was to compare the effects of eight-week hamstringstretching programs, implemented at different times during physical education classes(i.e., warm-up, cool-down, and both periods), on primary schoolchildren’s back-saver sitand-reach scores. Methods: A total of 275 schoolchildren (141 females and 134 males; age8.82 ± 1.63 years) were divided into four groups: the WUG performed stretching duringwarm-up, the CDG during cool-down, and the MXG during both. The NSG followed thestandard classes of physical education without any stretching. During physical education classes WUG, CDG, and MXG performed a 4 min stretching program twice a week.Hamstring extensibility was assessed before and after the program using the back-saversit-and-reach test. Results: The CDG is the one that achieved statistically significant improvements compared with the WUG, MXG, and NSG (p ≤ 0.01; d = 0.50–0.71). Moreover,the CDG statistically increased the percentage of schoolchildren achieving healthy hamstring extensibility from pre-intervention (49%) to post-intervention (66%). Conclusions:This knowledge could guide teachers to design programs that guarantee feasible andeffective development of hamstring extensibility in the physical education setting.
