Figure 3.

Mean surface EMG traces for each muscle (columns), angle (rows), and position (bright red for position 1 and dark blue for position 2). Significance between plots with P < 0.05 was calculated based on a two-sided t test of the mean of the central 4 s of each sEMG trace to compare the activity of the contraction. *Significance between angles in position 1. †Significance between angles in position 2. #Significance between position 1 and position 2 for the same angle; n = 17 (male: 9; female: 8). RF, rectus femoris; VL, vastus lateralis; VM, vastus medialis; ST, semitendinosus; BF, biceps femoris.
