During resistance training, why does eccentric contraction induce greater muscle hypertrophy compared to concentric contraction at the same load?

💡 Explanation

Eccentric contractions cause greater muscle damage at the sarcomere level because they resist lengthening under load, thereby inducing more significant mechanical disruption. This triggers a more robust repair and remodeling response, therefore promoting hypertrophy. Rather than limited activation, the process amplifies signaling cascades.
