Evidence from multiple studies demonstrates that concentric and eccentric muscle contractions trigger distinct physiological, cellular, and functional adaptations. Eccentric contractions often elicit unique signaling pathways, greater localized mechanical power, and distinct architectural or inflammatory responses compared to concentric contractions.
The retrieved papers consistently show that concentric and eccentric contractions produce distinct physiological effects, including differences in reactive oxygen species generation, inflammatory and fibrinolytic responses, muscle architecture adaptations, and strength profiles. Therefore, the claim is supported.
