| Abstract: | The purpose of this study was to examine the effects of different amounts of whey protein in carbohydrate–electrolyte (CE) drinks on post-exercise rehydration. Ten males completed 5 trials in a randomised cross-over design. A 4-h recovery was applied after a 60-min run at 65% VO2peak in each trial. During recovery, the participants ingested a high-carbohydrate CE drink (CE-H), a low-carbohydrate CE drink (CE-L), a high-whey-protein (33?g·L?1) CE drink (CW-H), a medium-whey-protein (22?g·L?1) CE drink (CW-M) or a low-whey-protein (15?g·L?1) CE drink (CW-L) in a volume equivalent to 150% of their body mass (BM) loss. The drinks were provided in six equal boluses and consumed by the participants within 150?min in each trial. After exercise, a BM loss of 2.15%?±?0.05% was achieved. Urine production was less in the CW-M and CW-H trials during recovery, which induced a greater fluid retention in the CW-M (51.0%?±?5.7%) and CW-H (55.4%?±?3.8%) trials than in any other trial (p?p?p?p??1 in the current study. |
