Quick takeaways

  • Muscles transmit force through the connective tissue matrix, not by directly pulling on tendons, preventing sliding forces and reducing the risk of injury.
  • Factors beyond muscle size, such as the integrity and function of the connective tissue, significantly contribute to force transmission and overall strength.

The importance of muscle tendon ligament bone system in force transmission

The muscle tendon ligament bone system plays a crucial role in force transmission in the body. Contrary to the common belief that muscles directly pull on tendons, the forces developed during muscle contractions are transmitted through the connective tissue matrix, which is critical for proper force distribution. The force transmission process involves the interaction of thousands of muscle fibers within a muscle, allowing the whole muscle to shorten and generate force. This connection between muscle fibers prevents sliding forces within the muscle, reducing the risk of injury and maintaining overall muscle health.
