Located in the lower back, the lumbar region is composed of vertebrae , muscles and ligaments. The spine has intervertebral discs, small pads made ​​of cartilage which are inserted between the vertebrae (bones of the spine ) . Any injury or disease affecting the muscles , ligaments and intervertebral discs can cause back pain.

People who are overweight , have an incorrect posture or whose back muscles and abdomen are low have a higher risk of injury to the lower back risk.
causes

In most cases it is not possible to find the cause of back pain . However, the most common causes of low back pain is the strain of a muscle or ligament . If back pain occurs suddenly , it's usually a sign of muscle tears, ligament sprain or a disc problem . The pressure exerted on the disc and can cause it to swell out , pushing the cartilage on the sides. The cartilage then press on the nerve cord of the spine, causing intense pain.

Cause of injury to players bodybuilding:
1-Failure to perform warm-up exercises adequate and appropriate.
2-Perform Abdominal exercises while the Cotton muscle stressful, A result of the training exercises the back and legs before exercising abdominal exercises.

Many diseases such as osteoporosis , osteoarthritis , fibromyalgia , ankylosing spondylitis and spinal stenosis can cause back pain. Pregnancy can also cause back pain because of overweight , changes in the strength of the muscles and ligaments , and also because the baby's head can compress the spinal nerves . Subjects with overweight are also more prone to have back pain due to a lower position and the extra pressure exerted on the discs and muscles.

Some medical conditions (eg . Diseases of the gallbladder and stomach ) can cause back pain. When pain is felt in one part of the body other than where would expect to find, it is described as " referred pain ".

The importance of warm-up exercises before exercise


Why is it important to warm up before exercise?

Warm is the act of preparing for the event or workout or exercise during practice for a short time before that. Warm-up helps reduce the risk of aches and pains that come with exercise. Physiological reason to warm up the system is to help your blood circulation to pump oxygen-rich blood to the working muscles. The idea is to increase the session throughout the body in a gradual manner. Even preparing proper warm body safely to the increased demand of exercise. Cold muscles do not absorb shock or impact as well, and are more prone to infection.

Help warm you prepare mentally and physically for exercise and reduces the chance of injury. During warm-up, and can often any injury or illness you have to be recognized, and to prevent further injury. Other benefits appropriate warm up as follows:

Increase the circulation of blood through your tissues, which makes muscles more flexible.
Increase the delivery of oxygen and nutrients to the muscles. This prevents you from breathing early exit.
Preparing to stretch your muscles
Preparing your heart to an increase in activity, and prevent a rapid increase in blood pressure
Prepares you mentally for the next exercise

Increased muscle temperature - and high temperatures inside the muscles that are used during the warm-up routine. Muscle temperature both contracts more forcefully and relaxes more quickly. In this way can enhance both speed and power. Also, the likelihood of excessive muscle and much less damage.
Increased body temperature - and this improves muscle flexibility.
Aneurysm - and this reduces the resistance to blood flow and decrease stress on the heart.
Improve the cooling efficiency - through the activation of heat dissipation mechanisms in the body (efficient sweating) an athlete can cool efficiently and help prevent overheating early in the event or race.
Increase the temperature of the blood - blood temperature increases as it travels through the muscle. With high blood temperature, and oxygen binding to hemoglobin weakens oxygen is more readily available in the muscle, which may improve stamina.
Average improvement movement - is to increase the range of motion around the joint.
Hormonal changes - your body increases its production of hormones responsible for regulating various energy production. During warm-up this balance of hormones increases the carbohydrates and fatty acids available for energy production.
Mental preparation - and warming up is also a good time to mentally prepare for this event by clearing the mind, increase concentration, and review the skills and strategy. Can also relax positive images of the athlete, and building focus.
