Introduction the fitness levels have been increased thanks to more complete workouts, a more intense physical and psychological preparation, and even a few materials joint sports custom and ergonomically adapted to the anthropometric measures of each athlete in order to increase their stability, your muscle strength, control your fatigue and thereby increase the performance of all their sporting skills. Ergonomics, understood as multidisciplinary methodology is intended to adapt the products, systems and artificial environments to the needs, constraints and characteristics of users, improving its efficiency, safety and well-being, is giving rise to a growing between different professionals in engineering interest, medicine, psychology, sociology, architecture, or design of the sporting, among others (3). In handball, as well as in other team sports, each player plays a specific role during the game but with the peculiarity that releases all performed to goal, being many times performed in suspension, so it must have a physical form perfect thigh and strong leg or support (15).

After the corresponding literature review found that only a commercial home manufactures and distributes technical socks that improve aerobic and anaerobic performance of the athlete in high competition according to previous studies for that entity.
And this is supported by a study conducted by the Centre of Zaragoza sports medicine, concluded that article saying that in sports of predominance of upper limbs, like canoeing, the redistribution of flow through compressive mesh in the lower limbs produces a significant improvement in VO2 Max. and the maximum lactatemia, an improvement in energy efficiency and a smaller lactatemia by load. All positive effects for competition performance.
