Abstract
Post-exercise chocolate milk consumption has been shown to improve subsequent endurance exercise performance following a short recovery period with limited food availability, presumably due to added carbohydrate (CHO) and protein (PRO). It is unclear how post-exercise nutrition strategies affect subsequent dietary intake when the duration of recovery is prolonged and diet is not restricted. PURPOSE: To examine the influence of post-exercise supplementation of CHO and PRO on the quantity and timing of macronutrient consumption during a 30-h recovery period. METHODS: Twelve trained, male cyclists (21.7 ± 1.8 y, 63.0 ± 4.1 ml·kg-1·min-1) carried out a glycogen-depleting exercise bout followed by a 2-h supplementation period and 28 h of free-living recovery. During 2-h supplementation, subjects consumed equal volume of reduced-fat chocolate milk (CM; 2.0 g of CHO·kg-1, 0.5 g of PRO·kg-1) or a sports beverage (SB; 0.8 g of CHO·kg-1, 0 g of PRO·kg-1) in a single-blind, randomized design. Following supplementation, individuals’ food log was recorded during the remaining 28-h recovery. Two-way repeated measures ANOVA was performed to examine the effects of treatment and time on the voluntary food intake. If a significant interaction effect was detected, paired t-test was used to compare the treatments at each time point. RESULTS: Total food intake over the 28-h free-living recovery did not differ (CM: 63.6 ± 2.9 kcal·kg-1, 8.0 ± 0.5 g CHO·kg-1, 2.4 ± 0.1 g fat·kg-1, 2.6 ± 0.2 g PRO·kg-1, SB: 68.3 ± 4.3 kcal·kg-1, 8.5 ± 0.5 g CHO·kg-1, 2.5 ± 0.2 g fat·kg-1, 2.9 ± 0.3 g PRO·kg-1). However, a significant interaction effect (treatment × time) revealed that eating patterns were different between the two treatments during the initial 12 h of the free-living recovery period, indicating that the SB group consumed a relatively large portion of food in the early phase of recovery and gradually reduced their intake to the end of the day. By contrast, the modified pattern was not observed during remaining recovery period. CONCLUSIONS: Athletes’ dietary behavior can be altered by ingesting supplements following strenuous exercise for hours but this effect does not last long enough to change the daily food intake as a whole.
