Figure 5. Rate of rise in the biceps femoris EMG signal (EMG/M, %.s⁻¹) in time intervals of 0–25, 0–50, 0–75, 0–100 ms, post contraction onset, and maximal rate of rise during the first and second half of the trial.

*denotes a significant difference from the start of the half (p<0.05). † is p<0.05 for difference between halves for the reduction from the start of the half. Data are mean and SD.
