Integrative physiological adjustments support the dramatically increased and sustained metabolic rates of contracting skeletal muscles during exercise. Accordingly, the capacities of the cardiovascular, hematological, and skeletal muscle systems to deliver, carry, and utilize O2, respectively, are directly related to an individual’s ability to perform exercise. The general plasticity of these physiological systems is well documented, but the mechanisms underpinning this plasticity are insufficiently characterized.
Dr. Martin MacInnis, PhD, leads a research group interested in how physiological systems respond to acute and chronic exercise stimuli to improve aerobic capacity and exercise tolerance and the factors that mediate these responses.
- The molecular and physiological mechanisms that regulate skeletal muscle mitochondria density and red blood cell volume in humans;
- The responsiveness of skeletal muscle mitochondria density and red blood cell volume to different exercise training stimuli (e.g., intensity, duration, frequency);
- The influence of hypoxia on acute and chronic responses to exercise; and
- The influence of biological sex on acute and chronic responses to exercise.
