Back pain is the most common musculoskeletal pain affecting all ages and all the population categories. It is the most common cause of work disability in patients less than 45 years. They are frequently recorded in both those who practice a sport, and the sedentary. They can range from mild pain, nagging, to severe, incapacitating. Back pain causes are complex and varied.  
It was found that 70-75% of back problems occur in those who practice a sport. Among sports, the great potential of back injury are football, volleyball, basketball, racquet sports, weightlifting and running speed tests and those with less potential for damage: jogging, skiing, hockey and bodybuilding.   
 
In general, injuries resulting in back pain caused by wrong moves that lead to small or microscopic lesions of muscle stretch and tendon are easy to treat.  
 
Collar spine is composed of 33 vertebrae that act in order to maintain verticality unit, protecting the spinal cord, pressure redistribution and facilitate movement of flexion-extension. If these vertebrae become inflamed, move or exert abnormal pressure on intervertebral discs, back pain occurs. Collar is supported by ligaments and muscles, stretch or damage that may have a muscle spasm causing back pain expressed.  
 
Another cause is herniation of the intervertebral discs. It is usually the most severe disease of the spine in the lumbar region necklaces. It is produced by “sliding” side or back of an intervertebral disc. It is composed of a soft substance consistency, but also elastic, which is designed to absorb mechanical shocks between vertebrae. It makes a compression on the nerve, which leads to pain at lumbar irradiation on the same side leg. To elders discs lose elasticity and fluid consistencies, shrinks and thus abnormal approaching faces joints of the vertebrae causes irritation of adjacent nerve.  
For bodybuilders and lifters, for example, most problems appear by moving a weight lifting from the ground plane and possibly slightly curved back wheel axially. It is therefore essential to learn correct exercise and wearing a wide belt, which set the lumbar region. We must always have in mind that these exercises (and any other movement of a weight lifting from the ground) to run with your back straight, even in light extension. Movement must be controlled throughout it. Sudden movements are prohibited. It is also recommended especially beginners paying special attention to the exercises that are designed to develop abdominal and back muscles.  
 
Assuming that an accident occurred and lumbar pains appear, which immediate measures should be taken?  
 
First, it must interrupt any physical activity that might require middle. In most severe cases, bed rest is mandatory. It is recommended a settlement with a higher consistency surface (a harder mattress, possibly a board under the mattress, or even on the floor). Two positions are recommended:  sitting back with a pillow placed under your knees  sat on one side, knees to chest and brought her with a pillow between them  If you find spastic muscle contractions, is indicated local application of ice and / or massage. These measures diminish spasm and associated pain, but are recommended only during acute illness. Later, back muscles to relieve rigidity heat may be applied locally in the form of compresses or warm baths. For reducing muscle spasms, joint and ligament inflammation and pain may be associated mild anti-inflammatory medications, with physiotherapy, spasm and dorsal muscle inflammation can be reduced significantly. In addition, the indication of a specialist physiokinetic therapy athlete may follow a specific training for rehabilitation and strengthening of certain muscle groups to prevent the occurrence of other painful episodes. This training is designed to improve flexibility and strength back structures.  
 
In some cases, especially those who are seated long may recommend wearing a special corset to keep necklaces and relaxes pain’s rectilinearity. To be remembered: small changes in lifestyle, in terms of how to sleep , to stay seated or standing can save us big problems. Is often sufficient minimum control posture to prevent the occurrence of other painful episodes?
