Exercise Physiology Scientific Journals

 Exercise physiology poses a substantial increase in body demand as compared to our resting state. At rest, our nervous system retains a parasympathetic tone that affects respiratory rate, cardiac output, and various processes of metabolism. Exercise improves the sympathetic nervous system and will induce the body to respond integrally. This response helps to maintain a suitable level of homeostasis for increasing physical, metabolic, respiratory, and cardiovascular demand. Exercising affects many human physiological processes having to adapt and preserve homeostasis, which is the body's inner equilibrium. Homeostasis is threatened by the increased demand for O2 and nutrients while exercising, the need to get rid of CO2 and metabolic waste products, rising temperature and acid imbalance, and differing hormone levels.
