The Schools of Kinesiology (UBC Vancouver) and Health and Exercise Sciences (UBCO) are co-hosting a weekly webinar series featuring current research of their faculty members. The series runs May through June. All are invited to attend these free academic presentations on Friday afternoons from 3:00pm-4:30pm.
Dr. Robert Boushel, professor and director of the School of Kinesiology, presents on ‘Cardiovascular and muscle metabolic adaptations to dynamic exercise training.’
Presentation Description:
Exercise training induces changes in the structure and function of the cardiovascular and muscular systems, contributing to enhance or alter the regulation of oxidative energy production. The oxygen uptake of an individual is a standard measure of oxidative energy metabolism and an indicator of improved fitness, the efficacy of exercise training programs and the health-promoting effects of exercise.
A greater pumping capacity of the heart together with intrinsic vasodilatory and autonomic control of blood vessels directs more oxygen to muscle with an expanded capillary volume to enhance oxygen diffusion into muscle. Mitochondrial biogenesis leading to increased mitochondrial volume enhances overall oxidative ATP production from fat and carbohydrate. Improvements in maximal oxygen uptake are not equally attributed to cardiovascular and muscle systems. Three studies in humans involving low-to-high intensity exercise will highlight the variable contributions of cardiovascular and muscle systems to improvements in oxidative energy production, including a recently described role of mitochondrial O2-affinity.
There will be a Q&A session moderated by Chris McNeil for UBCO-based talks and Jean-Sébastien Blouin for UBCV-based talks.
