Abstract

We investigated the bioelectrical activity of muscles when performing exercises for accurate power graduation during balance training (unbalanced surface training). According to the findings, it is important for the development of coordination to form the ability to dose muscular power and to distribute the load between the muscles when performing comprehensive coordination actions. It is accompanied by the multiphase EMG and synchronous achievement of peak amplitude and frequency characteristics of EMG. Reduced accuracy of test effort during the unbalanced surface training is accompanied by an increase in the number of multi-phase EMG and decrease in the number of EMG with the presence of hypersynchronous high-amplitude potentials. The accuracy of movements is provided by regulating external and internal power related to the human body arising when implementing a motor task. In this case, the object of control is muscular efforts that induce and regulate movements rather than the movements themselves. One of the ways to improve the coordination abilities is to develop the accuracy of perception and reproduction of efforts applied when dealing with various kinds of motor tasks. The purpose of the present research was to investigate the bioelectric activity of muscles when performing exercises intended to train accurate power graduation in the context of balance training. It can be assumed that hypersynchronous potentials are provoked by strenuous training as a result of the summation of action potentials of a large number of synchronized motor units. The low intensity muscle work is accompanied by low frequency nerve impulses and the involvement of a small number of motor units, resulting in multi-phase EMG registered.
