Muscles that act to stablilise the bone where the prime mover is acting to allow efficiency of movement and maximal contractile force to be developed if required. Stabilisers
When muscles on one side of a bone or joint relax to accomodate contraction on the other side of the bone or joint. Reciprocal inhibition
The optimum state of fatty acids in order to enable storage. Triglyceride stores
When the electrical impulses reaches a certain threshold, all of the fibres of that motor unit will contract at the same time and as forcefully as possible. However, until this threshold is reached or surpassed, none of the fibres will contract. All or nothing principle
