Concentric Contraction The muscle produces enough tension to overcome the weight or effect of gravity. The muscle shortens or contracts whilst completing a movement Eg. Bicep curl. The bicep contracts as the weight is lifted.


Eccentric Contraction The muscle produces tension by lengthening and allowing the pull of gravity or the resistance to overcome it in a slow manner. Eg. lowering a barbel from above youru head.


Isometric Contractions When a muscle produces force but there is no change in the lenght of the fibres, an isometric contraction has taken place. " Wanting to stay in a held position". Eg. Hand stands, pilates, gymnastic rings.
