Electrical activity of muscles when performing basketball shots under partial sensory deprivations
There were studied the effectiveness of performance of basketball shots and specifics of electrical activity of muscles when performing basketball shots under partial sensory deprivations. To achieve this aim 40 male athletes, mean age - 21,06 ± 1,97 years, were examined. All research subjects were right-handed, without disorders of the vestibular, visual and motor systems. They were divided into two groups based on the level of development of motor skill in the exercises «free throw standing and jumper». The experimental group consisted of 20 students, training in the university’s basketball section, the control one included 20 students training by the conditioning program of physical education. It has been established that in the absence of motor skill visual analyzer plays the leading role in ensuring corrective actions, visual deprivation violates coordination of all muscle groups and reduces the efficiency of throws. The role of the visual analyzer is reduced in athletes, the reafference from vestibular and muscle-joint analyzers comes to the fore. The disorganization of muscular activity is expressed to a much lesser degree and is local.
