Introduction[edit | edit source]
Biology is a branch of science that deals with living organisms and vital processes, both in animals and plants[1].
Physiology and anatomy are two closely related branches of biology[2].
While anatomy is the science that investigates the structure of the body, physiology is the scientific discipline that deals with the processes or functions of living things[3]. Physiology derives from Ancient Greek φύσις (physis), meaning "nature, origin", and -λογία (-logia), meaning "study of"[4].
The major goals of physiology are[3]:
- to understand and predict the body’s responses to stimuli;
- to understand how the body maintains conditions within a narrow range of values in the presence of a continually changing environment.
Exercise physiology is the specialistic branch of physiology which study the acute responses and chronic adaptations to a wide range of exercise conditions.
Exercise physiology
[edit | edit source]
Exercise is one of the most common stimulii which perturbates human homeostasis[5].
Usually people think of exercise as a sport-related activity to increment performance and train athletes (such as basketball, football, volleyball, hockey players, weightlifters, runners, etc.). But physical exercise is also present during job-related physical activity (lifting loads, moving objects, walking and standing for 8 hours, etc.), activities of daily living (doing laundry, mowing the lawn, cleaning house, cooking dinner, etc.), and rehabilitation of patients, such as following a stroke or heart attack. In all of these non-sport-related activities, exercise is involved. Therefore, exercise physiology matters in all of these contexts.
The physiological response to exercise is dependent on the intensity, duration and frequency of the exercise as well as the environmental conditions[6].
During physical exercise, requirements for oxygen and substrate in skeletal muscle are increased, as are the removal of metabolites and carbon dioxide. Chemical, mechanical and thermal stimuli affect alterations in metabolic, cardiovascular and ventilatory function in order to meet these increased demands[6].
Muskuloskeletal System[edit | edit source]
If you need a recap on muscle physiology this video will be very useful.
