Effects of isocaloric carbohydrate-protein versus protein recovery drink on muscle function following resistance exercise
Intense resistance exercise (RE) can reduce muscle glycogen content and cause muscle damage, affecting muscle functional performance. Post-exercise ingestion of protein (PRO) and/or carbohydrate (CHO) may enhance muscle recovery, but its effects on subsequent performance are debatable. This study ai...

Intense resistance exercise (RE) can reduce muscle glycogen content and cause muscle damage, affecting muscle functional performance.

It was hypothesised that both CHO-PRO and PRO would induce greater recovery of muscle function (MF) compared to control (CON), but there would be no difference in recovery when comparing between CHO-PRO and PRO.
