During exercise, an increase in the energy yield from the catabolism of macronutrients requires the integrated responses of the cardiopulmonary and vascular systems to transport oxygen to our working muscle tissues. The speed or ‘kinetics’ of the muscles oxygen uptake is closely related to the depletion of finite intramuscular energy stores that portends towards the development of skeletal muscle fatigue resulting in exercise intolerance. My research interests include studying how the physiological mechanisms controlling the oxygen uptake kinetics are impacted by maturation, exercise training and nutritional interventions.
