Book Description
Purpose: The purpose of this study was to compare the efficacy of different carbohydrate-protein recovery beverages following heavy endurance exercise. Methods: Twelve well-trained male cyclists completed a glycogen-depleting trial followed by a 4 hour recovery period before completing a simulated 20-km time trial. During the recovery period, subjects consumed one of three isocaloric beverages [high-carbohydrate/low-protein (HCLP); low-carbohydrate/high-protein (LCHP); carbohydrate (CHO)] at 0h and 2h, as well as immediately following the 20-km time trial. Creatine kinase (CK), muscle soreness, isometric peak torque (MVC), and mental/physical fatigue/energy ratings were measured pre- and post trial. Glucose and lactate were measured during the glycogen depleting phase and subsequent exercise. Results: Subsequent exercise performance was not significantly different between treatments (LCHP 50.3±2.7 min; CHO 48.5±1.5 min; HCLP 48.8±2.1 min). No significant treatment*time interactions were observed for isometric peak torque (MVC), muscle soreness, or mental/physical energy/fatigue ratings. Creatine kinase levels pre- (LCHP 153.5±68.1; CHO 132.6±39.9; HCLP 137.0±41.1) and post exercise (LCHP 172.4±53.1; CHO 150.8±47.4; HCLP 146.6±27.4) were not significantly different between treatments. Conclusion: Recovery beverages containing equal caloric content and differing proportions of carbohydrate/protein provided similar effects on muscle recovery and subsequent exercise performance in well-trained cyclists.

Book Description
Recent research suggests that adding protein (PRO) to a carbohydrate (CHO) supplement can have substantial benefits for endurance exercise performance and recovery beyond that of CHO alone. CHO+PRO supplements are often commercially available formulations consisting of carbohydrates (dextrose, maltodextrin) and whey protein. The effects of a supplement containing moderate protein and a low-CHO mixture on endurance performance has not been investigated. Also, the effects of CHO+PRO supplementation in the form of a natural food, flavored milk, on measures of recovery from acute endurance exercise, as well as on chronic aerobic exercise training adaptations, have not been characterized. Therefore, in this series of four studies, the effects of CHO+PRO supplementation on the following areas of endurance exercise performance, recovery, and adaptation are investigated: acute endurance exercise performance, inflammatory and muscle damage markers, muscle glycogen resynthesis, activation of signaling proteins involved in the initiation of protein synthesis and degradation, subsequent endurance exercise performance, and chronic aerobic training adaptations (maximal oxygen consumption, oxidative enzyme activity, body composition, immune cell levels, and inflammatory markers). Study 1 demonstrated that a supplement containing a low-CHO mixture plus moderate protein significantly improved aerobic endurance when cycling at or below the ventilatory threshold, despite containing 50% less CHO and 30% fewer calories relative to a higher CHO beverage. Study 2 demonstrated that CHO+PRO supplementation in the form of chocolate milk (CM) is an effective post-exercise supplement that can improve subsequent performance and provide a greater intracellular signaling stimulus for protein synthesis compared to CHO and placebo. Study 3 found that post-exercise CM supplementation during 4.5 wks of aerobic exercise training improves the magnitude of cardiovascular adaptations more effectively than isocaloric CHO or placebo, while the fourth study demonstrated that post-exercise CM supplementation during 4.5 wks of aerobic training improves body composition more effectively than isocaloric CHO or placebo. The fourth study also demonstrated that 4.5 wks of training does not appear to perturb resting immune cell concentrations or markers of inflammation and muscle damage. Taken together, the results of this research series suggest that CHO+PRO supplementation extends endurance performance, improves recovery, and increases training adaptations more effectively than CHO or placebo.
