Slow and fast passive stretch of the medial hamstrings. (A) Knee angle (solid line) in slow passive stretch of the medial hamstrings muscle to determine the ROM (dashed line). (B) Muscle activity of the medial hamstrings during slow passive muscle stretch. (C) Knee angle (solid line) in fast passive stretch of the medial hamstrings muscle. The catch (asterisk) appeared before the end ROM (dashed line) was reached. (D) Muscle activity of the medial hamstrings during fast passive muscle stretch. The onset (square) of the EMG burst was determined at 3 SDs beyond the baseline activity. (E) Joint angular acceleration (°/s2) during fast passive muscle stretch. The appearance of the catch (asterisk) was determined at the moment of maximal joint angular deceleration. The time delay between onset of EMG activity (square in D) and the appearance of the catch (asterisk) is shown. Abbreviations: Ext., extension; Fl., flexion.
