1RM, 1 repetition of maximal strength; Reps, number of executed repetitions; HRmax, Maximum heart rate; VO2max, maximum oxygen consumption; IF + EX, intermittent fasting in conjunction with exercise group; EX, exercise group; Δ%, variation between pre and post of each group. Values expressed as mean ± standard deviation. Symbols: Difference within groups (post vs pre), p < 0.05, by ANOVA two-way repeated measures mixed model, post hoc Sidak. #Difference within group, by Wilcoxon test. Effect size: η2 = 0.51 (high for shuttle walking test).
