Mitochondrial dynamics proteins are increased in muscle after 8-week swimming training. Muscle homogenates were subjected to immunoblotting with MFN2 (b), Opa1 (c), Drp1 (e), Fis1 (f), or actin. Each bar represents the mean ± SE for muscles from eight mice. (n = 8) * p < 0.05 vs. sed+sal, ^# p < 0.05 vs. sed+col, ^δ p < 0.05 vs. exe+sal
