Fitness Levels Have Been INCREASED by more Comprehensive training, physical and Psychological preparation for more intense, and Even a custom sports equipment and ergonomically adapted to the Anthropometric Measures of Each athlete in order to Increase Stability joint, muscle strength STI, fatigue and thereby control Increase Their performance of all the sports skills. Ergonomics, Understood as a Methodology to help Multidisciplinary AIMS products, systems and artificial environments to the Needs, Limitations and Characteristics of users, Improving Their Efficacy, safety and welfare, is a growing interest Attracting Among Professionals in Various engineering, medicine, psychology, sociology , architecture, or design of sports equipment, Among Others (3). In handball, as in other team sports, Each player plays a specific role DURING the game But With The peculiarity That all do a shot on goal, Often Being Carried in suspension, so it must-have A Suitable physical form of thigh and leg strong or support (15). There are Several commercial companies take That Their business to sell and study the way a tech sock more comfortable for dog be an athlete in terms of practice at the time Performed and Who performs it, Spring, Summer, Autumn and Winter, No Nonsense Muscle Building warm environments, wet , dry, well, in Different weather conditions. After the relevant literature review found only a marketing firm That manufactures socks and Distributed technified aerobic and anaerobic That Improve performance of the Highly Competitive athlete previous studies According To That entity. And this is supported by a study by the Center for Sports Medicine of Zaragoza, the article Concluded by Saying That “dominance of upper limbs sports s, such as canoeing, redistribution of flow-through mesh in the lower extremities compression Occurs significant improvement in VO2 max. lactatemia and maximum improvement in energy efficiency and lower lactatemia per charge. All positive effects for the performance of competition. “(16) The redistribution of blood flow-through tech sock significant improvement occurs in VO2 max and maximum lactatemia. It Acts by Facilitating the oxygenation of muscle tissue. Both blood Increaser contribution in motion and at rest. Compression speeds decreasing venous return to oxygenated muscle mass, With more compression at the ankle and less at the calf. Highly elastic fabric does not That link. Tissue retention. Increases the effect jacket. Malleolus protection. Spongy tissue inside and outside to slip more Comfortably With The shoes. This study AIMS to Quantify the force exerted by an isokinetic dynamometer an athlete on That is always a specific Place at speed and allow joint movement Will not faster or Slower Than is pre-determined speed. It is important to know That resistance is pre-set (8).
