Antagonistic muscle action

A pair of muscles that work together to produce movement with one muscle contracting whilst the other muscle relaxes. e.g. the upper arm, as the arm flexes the bicep contracts and the triceps relaxes.

AgonistThe muscle that works to create the movement.

AntagonistThe muscle that works in the opposite way of the agonist.

Fixator

A muscle which acts as the stabiliser and helps the agonist work effectively of one part of the body during movement of another part.

FatigueMuscle tiredness when the body has a lack of energy.

Muscle fibre types

There are three types of muscle fibre that make up the skeletal muscles

Type I

Slow twitch fibres suited to low intensity

aerobic work. They can be used

continuously for long periods without

fatigue e.g. long distance running

Type IIaFast twitch fibres suited to high

intensity anaerobic work e.g. 400m

Type IIx

Fast twitch fibres that generate a much

greater force than other fibre types.

They fatigue very quickly e.g. 100m
