Final answer:
When an MTU produces more torque than resistance, it can result in movement if within the limit of the tissues. Excessive torque, however, can lead to tissue damage such as tendon or muscle injuries. Proper resistance training is essential to avoid injuries and enhance muscle growth and tendon strength.
Step-by-step explanation:
When an MTU (muscle tendon unit) produces more torque than resistance, the muscle will cause movement of a joint, often resulting in the lifting or moving of a load. However, if the muscle exerts force beyond what the tendon and joint can handle, it can lead to tissue damage. Training programs and physical therapy are designed to build strength gradually, allowing connective tissues like tendons and cartilage to adapt and reducing the risk of injury.
In scenarios where the resistance is insufficient in comparison to the torque generated by the MTU, the resulting movement would be swift and with less control, potentially leading to overextension or rapid deceleration that may cause strain or injury. Coaches and physical therapists often emphasize the importance of balance between muscle strength and resistance to promote muscle growth while maintaining joint health.
Repetitive or excessive loading can lead to overuse injuries, with possible damage to muscle fibers, the sarcolemma, and myofibrils, contributing to soreness and requiring repair through additional structural proteins. Properly executed resistance training enhances the strength of tendons and the development of connective tissue, which supports more powerful muscle contractions and provides a safeguard against injury.
