Increasing the load The principle of continuity in sports training is directly related to the principle of a gradual increase in training loads. At the same time, the increase in loads is not understood one-sidedly, in the sense of only physical exertion, but also includes increased requirements for technical, tactical and moral-volitional training. In the practical implementation of this principle, it is important that the loads constantly increase, since if the load is the same, work becomes habitual and only recovery processes take place in the body. With a constant increase in physical activity, in addition to recovery processes, there will be processes to increase health. In sports, this means improving athletic performance. Continue reading
Specialists from Tsukuba University built and tested a robotic training complex for volleyball players
The device consists of three pairs of robotic manipulators that move from side to side under the grid. The device performs the functions of blocking players, writes New Scientist.
The system is equipped with three players who can move at speeds up to 3.7 meters per second. The system has already been tested in training by members of the Japanese women’s team. Six players trained with the robot for eight days, while some noted that such a training is different in sensations from a real game.
Interestingly, the device can imitate the playing styles of future rivals. Continue reading
Innervation of the muscles of the shoulder girdle, rear view Oversaturated neuropathy as a disease is quite rare, although it can occur quite often among volleyball players. This is inflammation and the occurrence of complete or partial non-conductivity of the suprascapular nerve due to its mechanical infringement. The suprascapular nerve is a short branch of the brachial plexus with the beginning of the fifth and sixth cervical roots. This nerve extends laterally under the scapular-hyoid and trapezius muscles, then it enters the front notch of the upper edge of the scapula in the region of the suprascapular notch or notch under the scapular superior transverse ligament. Then he goes on the back side of the scapula, into the supraspinatus fossa. Then its branching appears, one branch passes through the supraspinatus muscle, and the second – through the scapular spine under the lower scapular transverse ligament into the infraspinatus fossa and the infraspinatus muscle.
