Abstrakt: Background: Because of its satiating effect, it has been widely purported that a high-protein beverage may reduce subsequent appetite and food intake in healthy aged individuals, therefore annihilating any supplemental effect.
Aims: The goal of the study was to examine the impact of a post-exercise protein supplement from dairy products in the hours following resistance exercise on subsequent energy intake, sensation of hunger, appetite and satiety in sarcopenic older men.
Methods: A randomized double-blind crossover study with three experimental conditions was performed. Nine sarcopenic older (64 ± 3 years) men participated in three experimental conditions: post-exercise protein supplementation made from (1) cow's milk (13 g of proteins); (2) rice milk (isocaloric protein-free beverage) and (3) water (control). Subsequent energy intake was measured with a test buffet and a food record over the rest of the day. Assessment of appetite, satiety and hunger were obtained by visual analogue scales at various times before and after the buffet.
Results: Appetite, feeling of hunger and satiety and subsequent energy intake were not significantly different between the three experimental conditions. However, when participants were supplemented with cow's milk, total fat intake during the day of the intervention was significantly lower than with other supplements (p ≤ 0.05).
Conclusion: Post-exercise consumption of protein supplements made from dairy products appear not to compromise daily nutritional behavior and does not confer the anticipated negative impact on nutritional intake in sarcopenic older men.
