Summary

The aim of this study is to understand how healthy muscle repairs in response to eccentric exercise by evaluating functional, metabolic and molecular measures. Furthermore, this study will aim to understand the repair mechanisms in elderly healthy muscle following eccentric exercise by evaluating the same measures and highlighting age-related differences in repair mechanisms which may account for the age-related loss in muscle mass. It is hypothesised that elderly muscle will have a lesser/ blunted repair process compared to young muscle.

To meet the aims of this study and to answer the hypothesis, this study protocol is as follows:

Baseline functional, metabolic and molecular values are obtained via functional testing and a muscle biopsy. Participants then perform eccentric exercise designed to induce functional decline and muscle soreness and the contralateral leg performs concentric exercise which isn't designed to induce soreness or functional decline. Using a time-course, various metabolic and molecular measures are taken prior to and up to 7 days post exercise to understand the mechanisms underlying muscle repair. In addition the use of a novel amino acid tracer (D2O) will allow for synthesis measures over the duration of the study rather than the typical tracer techniques which only capture \~12 hours of synthesis.
