Influence of a way of vising on changing parameters of the bioelectric activity of muscles of a hand at children aged 5-6 years catching the falling subject
The paper examines the bioelectric activity of muscles of a shoulder and forearm when catching the falling subject. The electromyogram of a deltoid muscle represents an interferential curve, showing a sharp shot-like surge in bioelectric activity. The electromyogram of a biceps of a shoulder is an interferential curve with intensive increase and decrease in bioelectric activity, and the electromyogram of muscles of a forearm represents an interferential curve with smooth increase and gradual decrease in bioelectric activity.
