EXSS2028: Exercise Physiology and Biochemistry
2021 unit information
This unit discusses the acute responses to exercise with a specific emphasis on the roles of the respiratory and cardiovascular systems in oxygen transport and the significance of sub-maximal and maximal oxygen consumption in the limitations to performance. The concepts of acid-base balance during exercise and of lactate and ventilatory thresholds will be examined. Furthermore, this unit develops an understanding of the specific metabolic response to exercise at the peripheral cellular level and the biochemical strategies that maintain energy balance during exercise and a return to homeostasis in recovery. Students will put theory into practice with laboratory tasks that encourage skill acquisition in the collection of real-time physiological data of the respiratory and cardiovascular response to exercise.

At the completion of this unit, you should be able to:
- LO1. show competency in maintaining exercise testing specific skills for the accurate measurement of core outcomes specific to aerobic exercise testing including: blood pressure; heart rate; safe preparation for cycle testing; collection of ventilatory gases
- LO2. understand how changes in metabolic rate dictate the need for regulation of gas exchange
- LO3. describe oxygen and carbon dioxide transport mechanisms with specific reference to the Fick equation; blood flow re-distribution; RQ and RER; O2 saturation
- LO4. describe the ventilatory response to exercise at constant and incremental work rate and to prolonged exercise
- LO5. understand the vasomotor (arteriolar) and venomotor (venous) systems and their specific role in the regulation of cardiovascular responses to acute exercise
- LO6. identify and describe mechanisms underscoring oxygen kinetics at exercise onset and in recovery and factors that influence acid buffer systems, ventilator threshold and anaerobic threshold
- LO7. appreciate the role of the mitochondria in oxidative and non-oxidative ATP re-synthesis with specific reference to regulation of the electron transport chain, TCA cycle and shuttling of oxidation/reduction agents
- LO8. describe the biochemical pathways by which macronutrients are stored and/or synthesised during rest and recovery as well as how they are catabolised during exercise at constant and incremental work rate as well as prolonged exercise
- LO9. describe key hormones regulating metabolic responses to exercise at constant and incremental work rate and to prolonged exercise in addition to fuel mobilisation such as ionic and fluid regulation and protein synthesis.
