Volleyball is a dynamic sport where rapid strength and in particular the explosive component, is essential. Nowadays, matches are plaid in high rhythm an there has been a development of the physical appearance of sensible athletes, both considering parameters related to muscle aspects and the average length of the athletes. The speed of the technical gesture is not limited to the lower limbs, like for example in skiing, but is also required for the upper limbs, particularly when smashing. Other peculiarities of this sport are the great neuromuscular co-ordination and the acrobatic qualities required when knocking-up and diving. However not important are the organic qualities of aerobic kind. Reason more why the specific card has been devised and structured with strength programmes for the lower and upper limbs. The typical training of the volleyball player must be based on a programming that foresees the dynamic development of strength through exercises of jumps and leaps with and without weights: short bursts; pliometry and activities for the upper limbs as throws; twists with weights and the use of a balance generally in a dynamic way. And, of course, the use of electrostimulation. An observation that arises spontaneously is directed to the possibility, thanks to electrostimulation, to act in a selective and specific way on those muscles of the back that are used to sink the arms for a smash. An aimed and well-studied work will allow the athlete to obtain evident results in the executive speed of the motor gesture. Volleyball players, together with athletic jumpers and trampoline jumpers and in a certain way also skiers, are the athletes who achieve the best results on the footboard of Bosco: this is an evident sign of the high level of mutual relation between power tests and tests of specificity of the technical gesture. Volleyball is not a contact sport and therefore fractures are really rare, while the number of inflammations of tendons and pain in the joint structures is rather high. In particular, the most frequent pathologies are distortions of the ankle and knee; tendinitis rotulee and painful syndromes in the shoulder, elbow and hand. The pain programmes on the specific card of Sintesi SK intervene with analgetic Tens current to solve this kind of problems.
