Filter by:The goal of this randomized, double-blind, parallel group interventional study is to evaluate the effect of ketone bodies on healthy older adults (65-85 y) during 5 days of bed rest. The main questions it aims to answer are: Does supplementation of ketone bodies prevent the typical decline in muscle protein synthesis, muscle size, muscle function, insulin sensitivity, and muscle mitochondrial function that occurs in response to bed rest? Researchers will compare ketone supplements (KET) to an energy matched control beverage (carbohydrates and fats) to see if the ketones can rescue the decline in muscle protein synthesis rates, muscle loss, muscle function, insulin sensitivity, and mitochondrial function due to 5 days of bed rest. This may positively impact the heath of older adults subjected to bed rest.
The purpose of the proposed project is to determine if short-term dietary supplementation of magnesium will improve performance during a series of lab-based exercise tests, will favorably modify the gut-microbiota, and will augment skeletal muscle mitochondrial function.
In this study 11 healthy volunteers will perform high intensity exercise training during 4 weeks. The exercise frequency will increase progressively during the first three weeks, followed by a fourth week with lower exercise frequency. 5 skeletal muscle biopsies will be donated throughout the study and 4 oral glucose tolerance tests will be performed after each training period.
Resveratrol, a compound found in red wine and dark-skinned grapes, will improve the function of mitochondria (energy producing components) within the leg muscles of moderate functioning older adults. The investigators will look at the role Resveratrol plays in improving physical function by studying the connection of changes in mitochondrial function and changes in physical function.
