Notes: Values are reported as mean ± SEM. LPro refers to a measured protein intake of 0.53 ± 0.02 g of protein·kg⁻¹·d⁻¹; MPro refers to 0.76 ± 0.02 g of protein·kg⁻¹·d⁻¹; and HPro refers to 1.06 ± 0.05 g of protein·kg⁻¹·d⁻¹.

^†

Percentage of body fat and fat-free mass were determined by whole body plethysmography.

^‡

Carbohydrate, fat, and protein intakes were different among trials (p < .0001).
