Background

Muscle force output is characterised by constant fluctuations, which can be quantified according to their magnitude and temporal structure. The ability to control muscle force (i.e. to generate smooth and accurate forces) is of critical importance for many activities of daily living, such as balance and locomotion. Our ability to control muscle force is affected by both acute (e.g. neuromuscular fatigue) and chronic (e.g. ageing) perturbations.

It has previously been demonstrated that there is an inverse relationship between muscle metabolic rate (measured using near-infrared spectroscopy; NIRS) and muscle force control, whereby increases in metabolic rate, caused by constant load fatiguing exercise, lead to a decrease in the ability to control force. Given the importance of muscle force control for activities of daily living, this relationship with muscle metabolic rate could have important implications.

The project

Manipulating metabolic rate can be accomplished not just with fatiguing exercise but also by changing the inspired oxygen fraction.

The primary aim of this project is manipulate the inspired oxygen using hyperoxia and hypoxia and assess the impact of this on muscle force control at a range of contraction intensities and during neuromuscular fatigue. This will involve a variety of advanced physiological techniques, including isokinetic dynamometry and both muscle and brain NIRS.
