Correlation analysis. FSR 0–24 h after unaccustomed acute resistance exercise was positively associated with the change in (A) whole body and (B) leg fat- and bone-free (i.e., lean) mass during 12 weeks of multimodal (RET + HIIT) exercise training (Phase 2). Linear regression lines of best fit are shown in black. Dotted lines indicate 95% confidence intervals. UT, untrained; TR, trained; FSR, fractional synthesis rate; RET, resistance exercise training; HIIT, high-intensity interval training.
