The stretching of a muscle fiber begins with the sarcomere, the basic unit of contraction in the muscle fiber. As the sarcomere contracts, the area of overlap between the thick and thin myofilaments increases (discussed above). As it stretches, this area of overlap DECREASES, allowing the muscle fiber to elongate.
STRETCHING AND FLEXIBILITY – Physiology of Stretching
- Hence when you stretch, the muscle fiber is pulled out to its full length sarcomere by sarcomere, and then the connective tissue takes up the remaining slack. When this occurs, it helps to realign any disorganized fibers in the direction of the tension. This realignment is what helps to rehabilitate scarred tissue back to health.

What does stretching do to muscle fibers?
Stretching keeps the muscles flexible, strong, and healthy, and we need that flexibility to maintain a range of motion in the joints. Without it, the muscles shorten and become tight. Then, when you call on the muscles for activity, they are weak and unable to extend all the way.
What happens to muscles when they are stretched?
When you stretch a muscle, your body responds by increasing blood flow to that area. The blood vessels around the targeted muscle widen to allow more blood to flow through, and your heart starts pumping more blood.
How does stretch affect muscle contraction?
When an activated muscle is stretched during activation, the force that is being produced increases significantly. After the stretch, the force declines but remains higher than that produced during isometric contractions at corresponding lengths1.
How does stretching help your muscle and ligaments?
Stretching increases your range of motion and flexibility by making your soft tissues, such as muscles and ligaments, longer by decreasing stiffness. It can also help improve your performance in your sport, help with soreness after exercise and lower your chance of injury.
What are the effects of stretching?
Here are five benefits that stretching has.
- Stretching can improve posture. Tight muscles can cause poor posture.
- Stretching can improve range of motion and prevents loss of range of motion.
- Stretching can decrease back pain.
- Stretching can help prevent injury.
- Stretching can decrease muscle soreness.
Does stretching do anything?
However, research has shown that stretching can help improve flexibility, and, consequently, the range of motion of your joints. Better flexibility may: Improve your performance in physical activities. Decrease your risk of injuries.
Is stretching important for muscle growth?
Stretching lengthens muscle tissue and increases flexibility, both of which allow you to perform strength building moves with greater range of movement, making the exercise more effective.
What happens when you start stretching?
Not only can stretching help increase your flexibility, which is an important factor of fitness, but it can also improve your posture, reduce stress and body aches, and more. Read on to learn more about the benefits of stretching, plus how to start a stretching routine.
What is released when you stretch?
When you stretch, your body releases chemicals called endorphins. These endorphins interact with the receptors in your brain that reduce your perception of pain. Endorphins also trigger a positive feeling in the body, a “high” if you will.
What is muscle stretching?
Stretching is a form of physical exercise in which a specific muscle or tendon (or muscle group) is deliberately flexed or stretched in order to improve the muscle’s felt elasticity and achieve comfortable muscle tone. The result is a feeling of increased muscle control, flexibility, and range of motion.
Does stretching tear muscle fibers?
Stretching too far: Pushing muscles beyond their ability can also lead to injury, such as tears in the muscle tendons and fibers.
How does stretching affect performance?
Stretching can improve circulation, muscle flexibility, range of motion, and consequently, help athletes perform better in workouts and in competition. When exercising, muscles repeatedly flex and contract.
What does stretching everyday do?
Regular stretching helps increase your range of motion in the joints, improves blood circulation and posture and alleviates muscular tension throughout the body, he tells. In addition, it enhances your athletic performance and may reduce the risk of injury, notes the fitness expert.
How does stretching improve flexibility?
It works because that kind of stretching loads the muscle with more force at a greater level of extension, which then tells the nervous system that the muscle can be strong and safe at that level of extension, she said.
Why stretching is important after exercise?
Stretching Reduces Lactic Acid – The body produces lactic acid whenever you exercise, which contributes to sore, achy muscles. Stretching can help reduce the accumulation of lactic acid throughout the body. It also relaxes tense muscles.
