What scientific principles underlie the effectiveness of stretching?
The effectiveness of stretching is grounded in several scientific principles. Stretching promotes flexibility by increasing the length of muscle fibers and connective tissue, which enhances overall movement capacity. It acts on the muscle spindle, sending signals to the nervous system that help prevent injuries during exercise. Additionally, stretching is beneficial for increasing blood flow to muscles, aiding in recovery. Research supports that dynamic stretching before workouts prepares the muscles for activity, while static stretching post-exercise helps alleviate tension, making it an integral part of any fitness routine.
