Data are means ± SE. RG, red gastrocnemius; WG, white gastrocnemius. P values for comparisons reflect the results for the post hoc analysis that has been carried out only when the 1-way ANOVA test results in a P value <0.05. Post hoc test P values:

^*P < 0.05 vs. WG;

^†P < 0.05 vs. basal;

^‡P < 0.10 vs. LBW;

^§P < 0.05 vs. LBW.
