Recent studies have reported that muscle power can be improved through stretching. However, the mechanisms underlying the power enhancement induced by stretching are not yet well understood. This study aimed to clarify the association of muscle fascicle length and antagonist muscle flexibility on muscle power output and velocity variables.

- - The study aimed to analyze the electromyography (EMG) activity of the biceps femoris (BF) muscle during the Nordic hamstring exercise (NHE) before and after a critical angle known as the break-point angle (BPA), using data collected through a smartphone app.
- - Researchers set out to validate the hypothesis that BF EMG activity would peak at the BPA and then gradually decline, measuring activity through specific knee flexion angles during the exercise.
- - Findings indicated there was no significant difference in EMG activity at BPA compared to peak activity, but BF EMG significantly decreased 20-25° after BPA, emphasizing the need for knee flexion exercises to maintain higher BF EMG at certain angles
