Protein Intake and Exercise-induced Muscle Damage
NCT ID: NCT06235476 Phase: NA Status: COMPLETED Enrollment: 199 Completion: 2025-07-31
Conditions
Sarcopenia
Interventions
whey protein supplement, mixed plant-based protein supplement, e-health application, isocaloric carbohydrate control
Summary
The goal of this clinical trial is to test the effect of different protein-enhancement strategies versus carbohydrate control on exercise-induced muscle damage in physically active older adults. The main question it aims to answer is:
What is the effect of three different protein-enhancement strategies (whey protein (WP), mixed plant-based protein (MPP), and use of protein-rich food products (PFP) on exercise-induced muscle damage in older adults compared to isocaloric carbohydrate control?
Participants will:
- Use a protein-enhancement strategy (WP, MPP or PFP) or carbohydrate control for a total of 5 weeks;
- Participate in a single walking bound (30/40/50 km) two weeks after the start of the study;
- Participate in a consecutive walking bound (4 days of 30/40/50 km) in the last week of the study period;
- Complete different questionnaires and give blood samples to test for muscle damage.
Primary Outcome
serum creatine kinase (CK) levels
