  1. 1Normalized within each muscle sample to the mean of the oxidative region. 2ANOVA mean using individual muscles as the unit of analysis (P = 0.002 for regional differences and P = 0.036 for protocol differences). *Significantly different from mean of oxidative region by paired t-test, p ≤ 0.05.
