Figure 4From: Lower-extremity joint kinematics and muscle activations during semi-reclined cycling at different workloads in healthy individualsEMG ensemble average (EEA) curves. EEA curves of all participants’ EMG linear envelopes across three workload conditions for (a) RF, (b) BF, (c) TA, and (d) GT muscles. The crank angle represents TDC to its next TDC, which is 0° to 360°.Back to article page
