Results of the OIDA measurements for crank angle. Illustration of the results of the optimal interval detection algorithm. Data is shown for the muscle groups: left quadriceps (LQ), right quadriceps (RQ), left hamstrings (LH) and right hamstrings (RH). The shown torque traces represent the average of 3 cycles. Blue traces correspond to passive cycles (without stimulation), red traces to active cycles (with stimulation) and orange traces to the generated net-torque (active minus passive cycles). Start and stop values define the interval in which the measured muscle group should be active (light blue shading). Please note: A crank-angle of 0° corresponds to a vertical downwards facing position of the right crank-arm, with increasing values in clock-wise direction (seen from the right side)
