Coingestion of protein and carbohydrate in the early recovery phase, compared with carbohydrate only, improves endurance performance despite similar glycogen degradation and AMPK phosphorylation
Abstract
Endurance athletes competing consecutive days need optimal dietary intake during the recovery period. We report that coingestion of protein and carbohydrate soon after exhaustive exercise, compared with carbohydrate only, resulted in better performance the following day. The better performance after coingestion of protein and carbohydrate was not associated with a higher rate of glycogen synthesis or activation of anabolic signaling compared with carbohydrate only. Importantly, nitrogen balance was positive after coingestion of protein and carbohydrate, which was not the case after intake of carbohydrate only, suggesting that protein synthesis contributes to the better performance the following day.

“Two different isoenergetic options have been shown to effectively promote glycogen resynthesis post-exercise: CHO (1.2 g/kg) and CHO-P (0.8 g/kg CHO + 0.4 g/kg PRO) [9–11].”

In the citing paper
“A negative nitrogen balance with a CHO-only beverage was also a primary finding for both Rustad et al. (2016) and Dahl et al. (2020) when endurance-trained participants consumed energy-matched recovery drinks and performed repeated bouts of high-intensity exercise and time to exhaustion cycling.”

“Dahl et al. (2020) reported endurance athletes (26.7 ± 1.7 years) were able to cycle 8.4 ± 1.8 min longer following a 5-hour recovery period, in favor of CHO-P as compared to an isoenergetic CHO beverage, despite similar glycogen synthesis between groups [11] [19].”

“Three previously published studies that have examined post-exercise isocaloric CHO (1.2 g/kg bm) and CHO-P (0.8 g/kg bm CHO + 0.4 g/kg PRO) drinks and recovery from exhaustive exercise in young endurance-trained males have demonstrated that glycogen resynthesis postexercise is not necessarily the primary determinant of endurance-based performance outcomes [10,11,41].”

“While the importance of immediate post-exercise protein intake remains debated in literature [59–61], this controversy largely arises from differences in study designs and varying recovery conditions [62, 63].”

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
