Changes of strength indicators at the angle tilting of sports stick in mas-wrestling
The idea of this study was based on the preliminary subjective sensations of the difference in traction force with angular displacements of a sports stick in mas wrestling. It was assumed that when the angle of inclination of the stick changes, the parameters of the athlete's pulling force will change because of the weakening of the grip of the hand by the stick. To confirm the hypothesis, the laboratory studies were carried out. The tested athlete in standing position performed the maximum by the strength and duration static pull for the stick with versatile grip of hands. The stick was connected with the chains and carbines to one side of the strain gauge. The other side of the strain gauge was attached to the floor. To measure the traction force at angular shifts of the stick, one end of the stick was also attached to the floor by means of chains and carbines, with the position of the hand on the stick being such that the grip of the little finger was below the grip of the index finger. The diameter of the stick is 33 mm. The results of the study of the traction parameters at various angular displacements of the stick made it possible to formulate a preliminary conclusion that the displacement of the slope of the stick by 30° considerably reduces the values of the maximum force. Further angular displacement of the stick at more than 40° also leads to sharp decrease in the retention time of the force.
