Deceleration
The controlled reduction of the body's speed, absorbing momentum in order to stop, slow, or prepare to change direction.
Definition
Deceleration is the braking half of movement: the ability to reduce velocity under control rather than simply running fast. It requires muscles to work eccentrically, lengthening while resisting, to absorb the body's momentum, and it is fundamental to stopping cleanly, defending, and setting up a change of direction.
Because sports such as basketball, football, tennis and padel involve constant stop-start play, weak deceleration limits how sharply an athlete can cut or reposition. Training often emphasises landing mechanics, controlled stops and the strength to tolerate braking forces. It is coached as a movement skill and is not presented here as injury prevention or medical advice.

Movement patterns
- BackpedalControlled backward locomotion performed while facing forward, staying low and pushing off the balls of the feet in short strides to stay reactive and keep play in view.
- CatchReceiving a moving object and securing it under control, absorbing its momentum by yielding along its path so kinetic energy is dissipated rather than rebounded away.
- Change of DirectionA planned redirection of the body from one movement vector to another, requiring an athlete to decelerate existing momentum and reaccelerate along a new line between two known points.
- CutA sharp, frequently reactive plant-and-redirect performed in a single decisive foot contact to evade an opponent or abruptly alter a line of travel.
- GlideGlide is continuous, low-resistance locomotion in which the body holds a streamlined shape so that momentum generated by a preceding propulsive action carries it smoothly across a surface or through a medium.
Skills
- BlockingThe skill of using the hands or body to stop or slow an opponent’s attack.
- Core stabilityThe skill of engaging the trunk muscles to keep the body strong and controlled through movement.
- BalanceThe skill of keeping the body stable and controlled while still or moving.
- SprintingThe skill of running or riding at maximum controlled speed over a short distance.
- Running formThe skill of running with efficient, relaxed and balanced movement.
Sports science
- Motor controlHow the brain and nervous system organise the muscles to produce coordinated, controlled movement.
- BiomechanicsThe study of how the body produces and controls movement — the mechanics behind every technique in sport.
- ProprioceptionThe body’s internal sense of where its parts are and how they are moving — the awareness behind balance and coordinated movement.
- Movement efficiencyHow economically the body performs a movement — achieving the goal with the least wasted effort.
- Energy systemsHow the body supplies energy for movement — the different pathways that power everything from an explosive jump to a long, steady run.
