Impact of protein supplementation on muscle health in older men

Assessing the Impact of a Leucine Enriched Whey Protein vs Isonitrogenous Whey on Muscle Protein Synthetic Responses in the Rested and Acute Post Exercise States in Older Adults

Not applicable Interventional University of Nottingham · NCT06971822

This study is testing whether a special protein supplement can help older men build and maintain muscle better than a regular protein supplement.

What this trial studies

This study investigates the effects of leucine-enriched whey protein compared to isonitrogenous whey protein on muscle protein synthesis in older male adults, particularly focusing on their responses both at rest and after exercise. The research aims to address sarcopenia, a condition characterized by muscle loss and functional decline in the aging population, by evaluating how different protein supplements can enhance muscle health. Participants will receive protein supplementation and their muscle responses will be measured to determine the efficacy of the interventions.

Who should consider this trial

Good fit: Ideal candidates for this study are healthy male volunteers aged over 65 who are not suffering from significant health issues.

Not a fit: Patients with active cardiovascular, respiratory diseases, or metabolic disorders may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to improved nutritional strategies for preventing muscle loss and enhancing physical function in older adults.

How similar studies have performed: Previous studies have shown positive outcomes with protein supplementation in older adults, suggesting that this approach may be effective.
