Electromyographic activity of hip extensor muscles during Nordic hamstring and razor curl exercises on leveled and inclined shanks

ConclusionNH40, the BFlh EMG activity equivalent to NH0, might be more effective for preventing recurrence of hamstring injury because the knee flexion angle at peak BFlh EMG activity remains within 30 °, combined with a high BFlh EMG activity.
