Electromyographic Activity During Nordic Hamstring Exercise in Male Soccer Players

Sponsor: Universidad de Extremadura

Summary

This observational comparative study evaluates the surface electromyographic response of the gluteus maximus and biceps femoris during the Nordic Hamstring Exercise in adult male soccer players with a previous hamstring muscle injury. Participants are classified according to their usual soccer discipline as 11-a-side soccer players or futsal players. All participants complete the same standardized Nordic Hamstring Exercise assessment during a single experimental session. Surface electromyography is recorded from the gluteus maximus and biceps femoris before, during, and immediately after the exercise protocol. The main objective is to compare normalized electromyographic activation between soccer disciplines during the exercise, with particular attention to peak muscle activation across six valid Nordic Hamstring Exercise repetitions. Secondary analyses evaluate the immediate change in normalized muscle activation from pre-exercise to post-exercise.
