Abstract
The purpose of this study was to determine the effects of a recovery beverage immediately after exercise on rates of muscle glycogen resynthesis in response to road cycling when nutritional supplementation was supplied during exercise and a solid meal was served two hours after exercise. Eight trained male cyclists, (25 +/- 4 years, 69.3 +/- 5.2 kg, VO2 peak=4.5 +/- 0.4 L/min) performed two 62 km outdoor training rides in a double-blind, randomized cross-over experiment. Subjects received a food bar and a commercial sport drink during each ride. A recovery beverage (40 g CHO+20 g PRO) or a placebo (PL) was administered 30 min post-exercise. At 2 h post-exercise, a solid meal was provided for both trials. There was no difference between trials at any time point for glycogen (140 +/- 9, 56 +/- 8, and 70 +/- 8 mmol/kg wet wt.−1/hr for pre, post, and 4 h post, respectively). The addition of a supplemental recovery beverage ingested soon after exercise did not significantly increase the rate of muscle glycogen resynthesis after 4 h of recovery when nutritional supplementation is provided during exercise and a meal is consumed 2 h after exercise.
