A woman demonstrating the ability to balance A waiter balancing wine glasses. Balance in biomechanics, is an ability to maintain the line of gravity (vertical line from centre of mass) of a body within the base of support with minimal postural sway. [1] Sway is the horizontal movement of the centre of gravity even when a person is standing still.
Cyclists may be trained and assessed by exercise physiologists to optimize performance. [1] Exercise physiology is the physiology of physical exercise. It is one of the allied health professions, and involves the study of the acute responses and chronic adaptations to exercise. Exercise physiologists are the highest qualified exercise ...
Dynamic Tension is a self-resistance exercise method which pits muscle against muscle. The practitioner tenses the muscles of a given body part and then moves the body part against the tension as if a heavy weight were being lifted. Dynamic Tension exercises are not merely isometrics, since they call for movement.
Sports science is a discipline that studies how the healthy human body works during exercise, and how sports and physical activity promote health and performance from cellular to whole body perspectives.
The receptor is the sensing component that monitors and responds to changes in the environment, either external or internal. Receptors include thermoreceptors and mechanoreceptors. Control centers include the respiratory center and the renin-angiotensin system. An effector is the target acted on, to bring about the change back to the normal state.
Physiology (/ ˌ f ɪ z i ˈ ɒ l ə dʒ i /; from Ancient Greek φύσις (phúsis) 'nature, origin' and -λογία () 'study of') [1] is the scientific study of functions and mechanisms in a living system.
(Example, cone photoreceptors adapt for daylight, and rod photoreceptors adapt for moonlight and starlight). A system's parameters vary according to predicted demand and adapt their sensitivities. While a wide range denotes a flexible and healthy system, when their evolved operating ranges are chronically exceeded, systems at all levels break down.
Dynamic balance is the branch of mechanics that is concerned with the effects of forces on the motion of a body or system of bodies, especially of forces that do not originate within the system itself, which is also called kinetics. [1] [2] [3] Dynamic balance is the ability of an object to balance while in motion or switching between positions.
