Final answer:
When an MTU produces less torque than resistance, it means the muscle is not generating enough force to overcome the resistance. This can happen due to muscle weakness, fatigue, or damage. Damaged muscles may lose the ability to produce the same amount of power as before due to the replacement of muscle fibers by connective and adipose tissue.
Step-by-step explanation:
When an MTU (muscle tendon unit) produces less torque than resistance, it means that the muscle is not generating enough force to overcome the resistance it is facing. This can happen due to various reasons, such as muscle weakness, fatigue, or damage to the muscles or tendons. For example, when muscles sustain significant damage, they may lose the ability to produce the same amount of power as before. This is because the damaged muscle fibers are replaced by connective tissue and adipose tissue, which cannot contract and generate force like muscles can, leading to a decrease in muscle tension.
