The kinetic chain
The idea that the body’s segments work as a linked chain, passing force from the ground up through the hips, trunk and limbs.
Overview
The kinetic chain is a way of describing the body as a series of linked segments — feet, legs, hips, trunk, shoulders and arms — that work together to produce movement. Rather than any one muscle acting alone, force is passed along the chain, each segment building on the last. In many powerful actions this happens from the ground up, with the legs and hips starting the movement and the smaller, faster limbs finishing it.
The idea helps explain why so much of a serve, throw or kick actually begins far from the hand or foot that delivers it. When the sequence is well timed, force adds up smoothly along the chain; when a link is skipped or mistimed, effort tends to leak away. How an individual sequences their own movement is best explored with a qualified coach.
The science
- The body works as linked segments that pass force from one to the next.
- In many powerful skills the sequence runs roughly from the centre outward.
- The legs and hips often generate force that the trunk and arms transmit and refine.
- Timing matters as much as strength — a well-timed chain adds force smoothly.
- It is a model for understanding coordination, not a rule for every movement.
Why it matters
- It explains why coaches cue footwork and hip rotation for actions that finish with the arm.
- It links rotational, throwing and striking skills across many sports.
- It underpins how power and coordination combine in fast, whole-body movements.

A fast indoor racquet sport played with a shuttlecock that rewards agility and touch.
Frequently asked questions
What is the kinetic chain?
It is a model that describes the body as linked segments — from the feet up through the hips, trunk and arms — that pass force along in sequence. It helps explain why powerful actions like a serve or a kick begin far from the point that finally delivers the force, and how an individual builds that sequence is best guided by a coach.

Movement patterns
- AccelerationThe athletic pattern of building speed from a standing or slow start by driving large horizontal forces into the ground to project the body forward.
- BoundAn exaggerated, horizontal springing stride that transfers from one leg to the opposite leg with a long flight phase, amplifying the mechanics of running.
- 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.
- Crossover StepA lateral or diagonal travelling step in which one leg crosses over the other with accompanying hip and trunk rotation, trading a stable base for greater reach and speed.
- 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.
Training methods
- PlyometricsPlyometrics are jumping and bounding drills that train muscles to produce force quickly, developing power and springiness through explosive movement.
- Tempo TrainingTempo training holds a firm, controlled 'comfortably hard' pace for a sustained stretch, teaching the body to sustain effort without tipping into a sprint.
