What data supports the effectiveness of the treatment Amino Acid Intake for older athletes?
Is increased protein intake safe for older adults?
Research shows that increased protein intake is generally safe for older adults, with studies indicating benefits like improved lean body mass and muscle strength. However, it's important to consider individual health conditions and consult with a healthcare provider before making dietary changes.36789
How does amino acid intake differ from other treatments for older athletes?
Amino acid intake for older athletes is unique because it specifically targets the increased need for essential amino acids like leucine to stimulate muscle protein synthesis, which becomes more important with age. This approach focuses on optimizing the timing and composition of protein intake to enhance muscle development, unlike general protein recommendations that do not account for age-related changes in muscle metabolism.210111213
What is the purpose of this trial?
Masters level cyclists are a population above the age of 35 years who frequently participate in prolonged as well as heavy-volume training. Like most endurance-trained athletes, a greater recommended dietary allowance (RDA) for protein of 1.2-1.4 g/kg/bw is suggested.Dietary protein intake is vital for maximizing the benefits of training and ensuring optimal recovery. Dietary recommendations traditionally have been determined through nitrogen balance techniques, however, recent research indicates how this method is potentially underestimating protein requirements. Therefore, there is a need to reassess current dietary recommendations in order to meet the demands of physical activity for highly active populations.Recent efforts to understand protein requirements during rest and following exercise have been completed using the indicator amino acid technique (IAAO). This non-invasive method is reported to provide a robust measure of protein requirements. However, there is limited work in older (≥60 years) active populations.The purpose of this study is to measure the protein requirements in master cyclists, following an endurance training session, using the non-invasive IAAO technique.
Eligibility Criteria
This trial is for male master cyclists aged 35 and above who regularly engage in intense training. Participants should be healthy, without any metabolic disorders that affect nutrition. They must not have dietary restrictions that could impact protein intake.Inclusion Criteria
