Proteomics-based identification of different training adaptations of aged skeletal muscle following long-term high-intensity interval and moderate-intensity continuous training in aged rats
Figure 1. Effect of MICT and HIIT protocols on physical performance and fiber cross sectional area. Changes in time to exhaustion (min) (A), grip strength (N·g–1) (B), maximum run speed (m·min-1) (C), inclined plane performance (D), relative gastrocnemius weight (E), absolute gastrocnemius weight (F), muscle fiber morphology (G), mean cross-sectional area (H), and frequency distribution of mean gastrocnemius fiber cross sectional area (I). SED, sedentary control; MICT, moderate-intensity continuous training; HIIT, high-intensity interval training; BW, body weight. Data were analyzed by one-way ANOVA followed by Tukey’s post-hoc test and are presented as mean ± SD. * p < 0.05 vs. SED; ** p < 0.01 vs. SED; # p < 0.05 vs. MICT.
