Representative data of torque and electromyography (EMG) signals during explosive muscle strength measurement in young and older male participants and schematic explanation of the onset of torque and EMG activity. a Plantar flexion torque, b EMG activity of the medial gastrocnemius, c EMG activity of the lateral gastrocnemius, d EMG activity of the soleus, e enlarged view of the time-torque curve around the torque onset in the young participants, and f enlarged view of time-EMG activity of the medial gastrocnemius curve around the EMG onset in the young participants. Black arrows represent the onset of EMG activity. Mmax, peak-to-peak amplitude of M-wave
