ClinConnect Summary

This clinical trial is investigating the protein needs of male cyclists aged 65 and older who train regularly. The study aims to find out how much protein these athletes require to recover effectively after endurance training sessions. Traditionally, protein intake recommendations have been based on older methods, but this trial will use a newer, non-invasive technique called the Indicator Amino Acid Oxidation (IAAO) to get a more accurate measurement of protein needs.

To be eligible for the study, participants must be healthy male cyclists who train more than four days a week and have a stable body weight for the past six months. They should also have a body mass index (BMI) within a certain range. Participants will need to attend several sessions in a lab to help gather data on their protein requirements. It’s important to note that individuals with certain health conditions or those taking specific medications may not qualify for the study. Overall, this research could help improve dietary protein recommendations for older athletes, ensuring they get the nutrition they need for optimal performance and recovery.
