ADAPT: Efficacy of a Dietary Supplement During and After Exercise (ADAPT)
Since 1948, health has been defined as "a state of complete physical, mental and social well-being, and not merely the absence of disease and infirmity" . However, a growing school of thought suggests that health represents an ability to be adaptable and flexible in response to daily stressors. It has been proposed that instead, the view of health should be "towards the ability to adapt and self-manage in the face of social, physical and emotional challenges", which has been termed "resilience".
The theory of "resilience" relates health to the body's capacity to manage daily stressors (such as physical activity or oxidative fluctuations) that challenge homeostasis, with the return to homeostasis resulting from several physiological stress responses. Although this is an all-encompassing model, and the effects of pathogens and other stress factors are also relevant, this study will centre on the physiological aspects on this theory, focussing on the disruption through exercise.
