ClinConnect Summary

This clinical trial is studying the effects of a supplement called β-hydroxy-β-methylbutyrate (HMB) on muscle recovery after exercise. Specifically, researchers want to see how taking 4 grams of HMB daily for 7 days helps improve strength and recovery in men who are used to strength training, especially focusing on their lower body after they experience muscle damage from workouts.

To participate in this study, you need to be a man between the ages of 65 and 74 who has been strength training for at least a year and works out at least three times a week. You should also be in good health, with a doctor’s approval to exercise. The study requires participants to have a specific level of strength and protein intake in their diet. If you’re currently injured, taking certain supplements, or have health issues that might affect your performance, you won’t be eligible to join. If you participate, you can expect to take the supplement for a week and undergo tests to measure how well your muscles recover after intense exercise.
