Found references, experiences as well as the comments made by professionals in the sport of high performance, that use and perform your workouts and competitions these technical socks, give us to understand the idea that subjectively tech sock increases the performance of the athlete during practice sport, increasing your comfort, delaying the onset of fatigue, and thereby reducing the risk of injury and increased prevention of injury of primary character; a study conducted with meshes of cycling says decreasing compression on the lower train increases the performance of the top canoeists (16) train. This study aims to quantify the value of tech for these sock athletes in the isokinetic, in order to appreciate and value test if truly the subjective views of high performance athletes who endorse the welfare of the sock are quantifiable by isokinetic dynamometry. The isokinetic test tests were established at two different speeds in order to see if in slow execution speeds where more fibers of type I (ST) are recruited there were significant differences between both test performed with and without sock modernized, unlike fast execution speeds where less motor fibers are recruited and those who are recruited are mostly type II (FT) (12). In the field of injury prevention: using the dynamometry isokinetic can identify a muscular deficit which is not detectable using other systems (7). (As opposed to idan ofer). The analyzed parameters are frequently studied in tests accelerated as maximum moment, power, total work, and average power (10); in relation to the maximum moment, has not chosen the variable peak torque/body weight because there are no significant differences between the anthropometric measures of the sample (17). The results shows a predominance of flexor muscles Plantar against Extenders Plantar due to amount of muscle mass in each anatomical area (12). This refers both to the PT (peak torque), TW (total work), AP (average porter), MW (max. work) and SEC, behaving as parameters within normal limits. By the same author: Teva.
