Brief summary
This study evaluated the effect of protein intake immediately after resistance exercise on lean mass, strength, and functional capacity gains in postmenopausal women. Participants were randomly assigned to protein-carbohydrate group (PC) (n=17), that ingested 30 g of whey protein immediately after exercise and 30 g of maltodextrin in the afternoon; and to carbohydrate-protein group (CP) (n=17), that ingested 30 g of maltodextrin immediately after exercise and 30 g of whey protein in the afternoon. Both groups performed the same resistance training protocol in the morning.
Detailed description
Both groups performed the same training protocol, differing only the time of protein or carbohydrate supplementation. The dietary assessment was made through the 24-hour food recall, being conducted at the beginning, middle and end of the intervention. Resistance exercises for upper and lower limbs will be performed, at 70% of one repetition maximum. One maximum repetition (1-RM), handgrip strength and 1-mile walk were performed.

Participants were randomly assigned to protein-carbohydrate group (PC) (n=17), that ingested 30 g of whey protein immediately after exercise and 30 g of maltodextrin in the afternoon; and to carbohydrate-protein group (CP) (n=17), that ingested 30 g of maltodextrin immediately after exercise and 30 g of whey protein in the afternoon. Both groups performed the same resistance training protocol in the morning, 3 times a week, at 70% of 1-maximum repetition (1-RM) during 8 weeks.
