Benefits of improving muscular elasticity
First, we must understand that joint mobility is a quality involutive, which means that we are born with the highest degree and as the years pass we lost the ability to a greater or lesser degree depending on several conditions: sex, sports, daily activities, accidents, injuries, etc.. The determination of the degree of mobility for each joint can not be generalized and must begin with a thorough self-study conducted by a professional with due discretion. We insist on the fact that excessive joint mobility is detrimental to stability and support desirable and may predispose to joint injury.
The absence of optimum mobility and muscle shortening undesirable in certain muscles resulting in serious injuries, including more frequent include: the deviation of the posture, poor adaptability of muscle to explosive movements, poor coordination, added caloric expenditure following the effort to which the agonist muscles to overcome the passive resistance of the antagonists shortened or broken fibrillar when the muscle is required in a rough stretch or forzado.Por against, a muscle elastic allows greater fluidity in the movement which is essential in sports that require a high degree of coordination, likewise, lets assume, with less impact , rapid voltage changes, especially in the phase transition from negative to positive during an isotonic contraction. Increased muscle elastic capacity allows more effective pre-stretch for explosive movements and also prevents certain types of injuries. Good to know that the muscle fiber is adapted to stretch by increasing the number of sarcomeres at the ends of the fiber. Experiments carried out with cats that were immobilized with a plaster bandage the soleus muscle showed that it was adapted by increasing the number of sarcomeres by 20%. Once released into the muscle, it was adjusted quickly to the original length. When the limb was immobilized with the muscle shrink in place, it was discovered that the fibers had lost 40% of the sarcomeres in series. These studies seem to show that the adjustment of the number of sarcomeres to the functional length of muscle does not appear to be directly under neuronal control. Rather, it seems to be a response to the amount of passive tension which is under the muscle. The athlete has a good range of range of movement can deal more effectively with situations in which your joints are required to limit risk, as in the case of pitchers gymnastics or athletics. Also in contact sports where there are situations of shock and falls, a flexible joint absorbs the impact better avoid possible injury or lessening its effects if it does occur. Despite all this, we should not be inclined to think that training the elasticity and are safe from injury. Many practitioners believe that sports a good level of elasticity is a guarantor to assume certain risks when athletic performance and to limit imprudent risk. I always say that the elasticity is like armor that can save in front of an arrow or a knife, but nothing can cope with a firearm.
