Modified Breath Test to Determine Anabolic Sensitivity Across Physical Activity States

Plain-language summary

Developing tools to detect when our bodies are more resistant towards protein synthesis is valuable for identification of when someone may be at risk of losing body or muscle mass such as with aging or certain diseases. The current study aims to refine our previous breath test method to be more effective at measuring changes in how the body processes protein in different situations, such as resting, reducing physical activity, and doing resistance exercise. We hypothesize that using a lower amount of dietary amino acids in our breath test will be effective at detecting lower amounts of amino acids used after exercise, and a greater amount with step reduction compared to normal activity levels
