Abstract:
Hamstring injuries are prevalent among athletes and anyone who engages in prolonged
physical activity. Hamstring Strengthening courses should focus on movements that involve
high hamstring activity to train the hamstring muscle specifically for sprinting. Therefore, the
goals of this study were to evaluate the hamstring muscle activity during sprinting and the
selected workouts, as well as to ex- amine the relationship between sprinting and hamstring
strengthening workouts. Athletes, trainers, and rehabilitation professionals can create
effective training plans by knowing which exercises cause the greatest muscle activity and
force output. This study makes use of a comparative and corre- lational methodology,
collecting electromyography (EMG) data during various hamstring exercises and sprinting,
then analyzing and interpreting the data to assess muscle activity and the association between
exercises and sprint performance. Studies discovered that various hamstring exercises produced varying levels of muscle activation, with the slide leg bridge exercise generating the
highest peak EMG activity. The Nordic exercise at 0 degrees showed a good association
(0.57) with sprint performance, while the lying kick showed a weak correlation (0.19) with
sprint performance. In conclusion, this investigation reveals valuable details regarding the
relationship between several ham- string strengthening workouts and sprint efficiency, as
well as the effectiveness of such exercises in terms of muscle contractions and exertion of
force. The results indicate that while the Nordic exercise at 0 degrees correlates best with
improved sprinting performance, the slide leg bridge exercise seems particularly
advantageous for hamstring activation. These results can help in the creation of focused
training protocols to improve sprint performance, hamstring strength, and avoiding injuries.
