Dr. Falk Mersmann, head of a research group at Humboldt University, specializes in muscle and tendon biomechanics. He reveals the crucial balance between tendon stiffness and muscle strength to prevent injuries. Personalized tendon loading strategies can enhance adaptations, while simplistic activities like running alone aren't enough for tendon health. He dispels myths about stretching reducing stiffness and argues that plyometrics might not boost tendon strength. Mersmann emphasizes understanding mechanical stiffness for effective injury prevention in athletes.
