Summary

This study will try to answer the following question: Will adding mini-squat exercises at different angles (30°,45°, and 60°) to leg press exercise influence quadriceps and hamstring strength and H:Q angle in football players?

Detailed description

Recent studies have highlighted the importance of exercise selection and angle specificity in resistance training, showing that different knee angles result in varied activation patterns in the quadriceps and hamstrings. However, current literature offers limited insight into the effects of integrating mini squat exercises with leg press training on injury prevention and functional outcomes in athletic populations. In particular, there is a lack of literature on how such a combined leg press and mini squat exercise at different angles influences the H:Q ratio, lower limb neuromuscular control, and performance in young male football players. Therefore, the present study aims to examine whether incorporating mini squats performed at varying knee flexion angles into a leg press training program can improve muscle balance and lower limb strength in football players. The findings may provide valuable guidance for physiotherapists, coaches, and sports scientists in developing evidence-based, angle-specific exercise protocols tailored to the functional demands of athletes.
