  • Values are mean (SD) and range [min, max]. One individual excluded from PRO due to incomplete food logs. CNTRL, control group; CHO, carbohydrate supplement group; PRO, protein supplement group. Values compared by one‐way ANOVA with Tukey's correction.

  • a Significantly different from CNTRL and CHO, < 0.01.

  • b Significantly different from PRO, = 0.02.
