Impact of Protein Content of Milk on Post-Exercise Appetite and Energy Intake

Summary

This study aims to investigate the acute effects of consuming milk beverages with different protein content on subjective appetite and energy intake in healthy adults following endurance exercise. Participants will complete an endurance exercise protocol and then consume one of three beverages: a high-protein milk, a regular-protein milk, or an isoenergetic and isovolumetric carbohydrate control drink. Subjective appetite ratings will be assessed using visual analogue scales (VAS) at multiple time points after beverage consumption. Appetite-related hormonal responses, including insulin and acylated ghrelin, will be measured via blood samples. Energy intake will be assessed through an ad libitum test meal. This study will help determine whether different types of milk consumed post-exercise influence appetite regulation, hormonal response, and subsequent energy intake.

Conditions

• Appetite
• Energy Intake
• Post-exercise
• Negative Energy Balance

Interventions

BEHAVIORAL

The study will investigate how different amounts of protein (0 g, 15 g, and 30 g) in post-exercise beverages affect appetite and energy intake following endurance exercise.

The study will investigate how different amounts of protein (carbohydrate control drink : 0 g, reguler milk : 15 g, and high-protein milk : 30 g) in post-exercise beverages affect appetite and energy intake following endurance exercise.
