Phosphocreatine, Glycogen Phosphocreatine, Glycogen It is obvious from the table above that Type IIx is the most powerful fiber but it doesn't last long because it mostly relies on anaerobic energy system. In contrast, Type I is the least prone to fatigue but it is not as strong because it mostly relies on aerobic energy system. Type IIa is somewhere in between.

An injury to a joint that involves a stretched or torn ligament. Muscle Strain A strain occurs when a muscle or the tendon that attaches it to the bone is overstretched or torn. Muscle strains are also called pulled muscles. Anyone can strain a muscle. However, people involved in sports or other forms of strenuous exercise are more likely to strain a muscle.

Muscles are bunches of fibers that can contract.

5 Simple Yet Powerful Ways to Take Care of Your Body

Muscle strains usually occur during activities that require the muscle to tighten forcefully. The muscle is strained either because it is not properly stretched, or warmed up, before the activity; it is too weak; or because the muscle is already injured and not allowed time to recover.

So, many muscle strains occur during exercise or sports activities. They can also occur when lifting heavy objects. What are the symptoms? When a muscle is strained, it hurts and is difficult to move.

You may also feel a burning sensation in the area of the injured muscle, or feel as though something has "popped.

A strained muscle might spasm, which means it contracts suddenly and involuntarily, causing severe pain. How is it diagnosed?

To diagnose a muscle strain, your doctor will examine the painful area, and ask how and when the injury happened. He or she may order other diagnostic tests, such as x-rays, to rule out any injury to the bone. What is the treatment? Muscle strains are treated with rest, ice, compression, and elevation, or RICE.

You will be told to rest the injured area to reduce pain and swelling. If the strain is in the leg or foot area, you may need to use crutches.

Ice packs are recommended at regular intervals as recommended by your doctor over the first few days after the injury. Ice causes the blood vessels to constrict, which reduces inflammation and pain.

Anti-inflammatory medications might also be used to relieve pain. Compression and elevation help to reduce swelling.

Your doctor may also recommend physical therapy to speed your recovery. You should avoid the type of activity that caused the injury until the muscle is completely healed.

Self-care tips You can prevent muscle strains by warming up for at least 10 minutes before participating in any strenuous exercise or heavy lifting. When you warm up, you increase the blood circulation to the muscle and prepare it for exercise.

Tendons are cords made of tough tissue, and they work as . The muscular system is the biological system of humans that produces movement. The muscular system, in vertebrates, is controlled through the nervous system, although some muscles, like cardiac muscle, can be completely autonomous.
