If muscles are not regularly stretched and contracted, how will the muscles be affected?

A. While muscles may become painful with disuse, pain is not the most consistent or defining result. The primary issue is loss of elasticity and shortening. B. Lack of regular stretching and contraction leads to muscle atrophy, shortening, and decreased elasticity, contributing to joint stiffness and reduced range of motion. C. Muscles do not become longer or remain flexed with inactivity; instead, they typically shorten due to contracture formation. D. Fibrosis and spasticity are more associated with neurological damage rather than simple disuse.
