چکیده انگلیسی
Objective: Many athletes perform resistance training and consume dietary protein as a strategy to promote anabolic adaptation. Due to its high satiety value, the regular addition of supplemented dietary protein could plausibly displace other key macronutrients such as carbohydrate in an athlete's diet. This effect will be influenced by the form and dose of protein. Therefore, this study assessed the impact of liquid whey protein dose manipulation on subjective sensations of appetite and food intake in a cohort of athletes. Design: Ten male athletes who performed both resistance and aerobic (endurance) training (21.2â±â2.3 years; 181.7â±â5.7âcm and 80.8â±â6.1âkg) were recruited. In four counter-balanced testing sessions they consumed a manipulated whey protein supplement (20, 40, 60 or 80âg protein) 1 hour after a standardised breakfast. Subsequent energy intake was measured 3 hours after the protein supplement using an ad libitum test meal. Subjective appetite sensations were measured periodically during the test day using visual analogue scales. Results: All conditions resulted in a significant decrease in ratings of hunger (50-65%; Pâ<â0.05) at the time of supplement consumption. However, there were no significant differences between the conditions at any time point for subjective appetite sensations or for energy consumed in the ad libitum meal: 4382â±â1004, 4643â±â982, 4514â±â1112, 4177â±â1494âkJ respectively. Conclusion: Increasing whey protein supplement dose above 20âg did not result in a measurable increase in satiety or decrease in food intake. However, the inclusion of additional whey protein supplementation where not otherwise consumed could plausibly reduce dietary intake.
