Table 2. Changes in single muscle fiber diameter, cross-sectional area, peak force, specific force, and maximal shortening velocity. Data presented as mean ± SEM. The number of muscle fibers n=20 per group; SHAM, sham operation; DN, denervation; DN-SM, denervation and electrical stimulation; CSA_F, cross-sectional area of single muscle fiber; ^*P<0.05, significantly different from SHAM; ^#P<0.05, significantly different from DN
