A: body weights of sedentary compared with trained rats from wk 0 to final body weights at the end of the training protocol (n = 9). Weights were recorded weekly. Data are reported as means ± SE; δsignificant differences between trained and sedentary for each individual week; *main effect for training status. Closed circles, sedentary; open squares, trained. B: lean mass and fat mass (n = 9). Analysis was conducted on the region of interest, which comprised lean mass + fat mass + bone mineral content. Data are reported as means ± SE; *significant differences between trained and sedentary (P < 0.05). Open bars, sedentary group; closed bars, trained group. DXA, dual-energy X-ray absorptiometry.
