ClinConnect Summary

This clinical trial is studying how taking collagen peptides (a type of protein) after resistance training can affect body composition and muscle strength in untrained overweight men aged 30 to 60. The researchers want to find out if combining collagen peptides with exercise improves lean body mass, muscle strength, and fat levels better than just exercise alone. Participants will be part of a controlled study, meaning some will receive the collagen and others won't, allowing for a fair comparison of results.

To join the study, men must be between 30 and 60 years old, have a body fat percentage higher than 25%, and have had a stable weight and eating habits for the last three months. However, those who exercise regularly, have certain health conditions, or have experienced serious health issues in the last five years may not be eligible. Participants can expect to engage in a structured resistance training program while receiving either the collagen peptides or a placebo. This trial aims to provide insights into how dietary supplements might enhance the benefits of exercise, making it an important opportunity for eligible men looking to improve their health and fitness.
