Final answer:
Massage techniques stimulating muscles directly should account for forces and torques. Coaches and therapists are knowledgeable in applying these principles for muscle treatment and recovery. Excessive force, however, can damage connecting tissues, requiring a careful application of massage movements.
Step-by-step explanation:
Massage movements designed to stimulate the muscle directly should be done with an understanding of the relationships between forces and torques. Training coaches and physical therapists apply this knowledge in the treatment of muscles and joints. A well-designed massage technique can apply the correct amount of force and torque to a muscle, which can aid in its recovery and strengthening.
Some therapies incorporate exercises under water to require more exertion and thus, strengthen the muscles further. It's essential, however, to ensure that these forces do not damage the connecting tissues in the limbs, such as tendons, cartilage, and joints which can sometimes be injured by excessive force, seen often in accidents or with athletes like weightlifters who might tear muscles and connecting tissues through intense effort.
