Muscle Fatigue
... when heavy objects are lifted. Most body movements use this type of contraction because the muscle must shorten and maintain a constant tension. Isometric (same length) contractions develop when a muscle is not allowed to shorten and the muscle tension increases. Pushing against a fixed object and s ...
