a contraction in which the muscle length remains constant as the tension in the muscle increases
A muscle contraction where there is no change in the length of the muscle fibres and there is no movement at the involved joints.
Muscular contraction that does not result in a change in the length of the muscle.
Muscular contraction in which tension is developed but no mechanical work is done.
A muscular contraction where the associated joints don't move, for example if you have to hold a heavy object in one place by contracting your biceps. This is a static action because there is no movement.
Keeping a muscle under tension without eccentric or concentric motion.
