Abstract
Abstract Background Hamstring flexibility is an important component of physical fitness in football players because football involves repeated sprinting, acceleration, deceleration, kicking, jumping and rapid changes in direction. Hamstring injuries represent a substantial proportion of injuries sustained by football players, making appropriate flexibility and conditioning strategies clinically relevant. Static and dynamic stretching are commonly incorporated into athletic training, although their comparative effects on hamstring flexibility remain debated. Objective To compare the effects of static and dynamic stretching exercises on hamstring flexibility in male football players over a four-week intervention period. Methods A pretest–posttest experimental comparative study was conducted among 40 male football players aged 18–25 years. Participants were randomly allocated into two groups of 20 participants each. Group A performed static hamstring stretching, while Group B performed dynamic stretching exercises. Both interventions were administered for 10–15 minutes per session, five days per week for four weeks. Hamstring flexibility was assessed before and after intervention using the Sit and Reach Test (SRT) and Active Knee Extension Test (AKET). Within-group changes were analyzed using paired t-tests and between-group post-intervention differences using independent t-tests. Results Both groups demonstrated statistically significant improvements in hamstring flexibility. In Group A, SRT increased from 25.10 ± 3.20 cm to 28.75 ± 3.10 cm, while AKET increased from 145.50 ± 4.40° to 150.40 ± 3.90° (p < 0.001 for both). In Group B, SRT increased from 24.90 ± 3.00 cm to 30.60 ± 2.80 cm and AKET increased from 144.80 ± 4.10° to 152.70 ± 3.70° (p < 0.001 for both). Post-intervention between-group analysis demonstrated statistically significant differences for SRT (p = 0.048) and AKET (p = 0.049), with greater changes observed in the dynamic stretching group. The mean SRT improvement was 3.65 cm in Group A versus 5.70 cm in Group B, while mean AKET improvement was 4.90° versus 7.90°, respectively. Conclusion Both static and dynamic stretching significantly improved hamstring flexibility in male football players following four weeks of intervention. The observed between-group results indicated greater improvement following dynamic stretching. Further adequately powered studies incorporating functional performance and injury-related outcomes are warranted.
