Data are mean ± SD. n, number of animals. Statistical significance (P < 0.05): ^a vs. initial BW; ^b vs. SPl; ^c vs. SCaf; ^d vs. Sedentary for the same column. BW, body weight. SPl, sedentary placebo. SCr, sedentary creatine. SCaf, sedentary caffeine. SCrCaf, sedentary creatine plus caffeine. EPl, exercised placebo. ECr, exercised creatine. ECaf, exercised caffeine. ECrCaf, exercised creatine plus caffeine.
