In physiology, the all-or-none law (sometimes the all-or-none principle or all-or-nothing law) is the principle that if a single nerve fibre is stimulated, it will always give a maximal response and produce an electrical impulse of a single amplitude. If the intensity or duration of the stimulus is increased, the height of the impulse will ...

In contrast to an average velocity, referring to the overall motion in a finite time interval, the instantaneous velocity of an object describes the state of motion at a specific point in time. It is defined by letting the length of the time interval Δ t {\displaystyle \Delta t} tend to zero, that is, the velocity is the time derivative of the ...
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 study of sports science traditionally incorporates areas of physiology (exercise physiology), psychology (sport psychology), anatomy ...

Organization is related professions with the goals of promoting the scientific study of human behavior in sport and physical activity, facilitating dissemination of scientific knowledge, and advancing the improvement of research and
Optical flow or optic flow is the pattern of apparent motion of objects, surfaces, and edges in a visual scene caused by the relative motion between an observer and a scene. [ 1 ][ 2 ] Optical flow can also be defined as the distribution of apparent velocities of movement of brightness pattern in an image. [ 3 ]
