Normalized cumulative frequency curve of T2 (CFZ) after supination exercise. The filled circles, open circles and closed squares indicate results obtained after pronation exercise of 25%, 15% and 5% MVC, respectively. The bold curves indicate the CFZ of resting muscles, and the mean (Zm) was 0 and the SD was 1.0. The bold vertical lines represent the threshold of the activated muscles (ZT = 2.56)
