Figure 7

Bar graphs showing the values of the coefficients of determination (r²) to determine the match between the shapes of the measured and predicted force-time responses of CFTs, VFTs, and DFTs (top to bottom) for quadriceps (N = 8), dorsiflexor (N = 7), and plantar-flexor (N = 9) muscles. For each pattern and each muscle, averaged r² values and standard error bars for each frequency are plotted. The horizontal dotted line in each plot demarcates r² = 0.80.
