[Analysis of selected parameters of functional system in accordionists]. / Analiza wybranych parametrów czynnosciowego zespolu wykonawczego u akordeonistów.

BACKGROUND: The aim of the study was to carry out a complex analysis of loading and overloading of a musician. MATERIALS AND METHODS: Eighty students of music school accordion class, and 60 students of colleges, participated in a pilot test. The test estimated the function of hand muscles, the body statics, the body posture, the presence of spinal curvatures, the time of straight reaction, the accuracy of movement, and the coordination of movement and vision. RESULTS: The study indicated better conditions for the function of hand muscles in accordionists, better indicators of static and dynamic muscular force, but the increased frequency of the disturbed body statics manifested by faulty posture and lateral curvature of the spine. CONCLUSIONS: In view of more frequent incidence of faulty posture and lateral curvature of the spine in accordionists it is necessary to perform corrective physical exercises in the course of musical education.
