Outcome measures
Primary outcome
The main study parameter is mitochondrial capacity, measured as the rate of recovery of muscle oxygen consumption after exercise measured using NIRS in the vastus lateralis, gastrocnemius and tibialis anterior.
Secondary outcome
Physical activity is monitored using a wearable accelerometer over a period of seven days and a 24 hour urine is collected in order to analyse markers of mitochondrial function in urine. Blood is collected to analyse markers of mitochondrial function in plasma.
Background summary
Ageing is associated with a decline in muscle mitochondrial function. Measuring muscle mitochondrial function is challenging and to routinely assess mitochondrial function in response to exercise and dietary interventions, practical, non-invasive and robust measurements are needed. Near-infrared spectroscopy (NIRS) is a novel technique that allows to non-invasively measure mitochondrial capacity in the human muscle. Although the technique is promising in measuring mitochondrial function during ageing, it is yet be established how age-related changes in mitochondrial function differ between different muscle types. The primary objective of this study is to measure mitochondrial capacity using NIRS in young and older healthy males in three different muscles (vastus lateralis, gastrocnemius and the tibialis anterior) to give insights on how age-related changes in mitochondrial function differ between different muscle types.
