    Muscle contraction involves the activation of the tension generating sites in the muscle fibers. The strength and weakness of a muscle contraction is determined by the degree of motor unit recruitment, the degree of muscle cross sectional area and muscle stretch, the force of the contraction and the velocity of the contraction.
