Abstract

One of the essential purposes of the performance of gymnastic exercises is to achieve the bodys motion in accordance with the description of the exercise. The main aspects of the uprise technique are the coordination of the muscle contractions in order to use the kinetic energy for the displacement of the body to its final position. The required energy for the performance of the uprise is achieved by the swing. The value of the kinetic energy for the rise depends on the displacement of the body in the vertical plane. In the case of an excessive value of kinetic energy, it is not possible to perform the uprise by means of muscle contractions only. Too great a value of kinetic energy disturbs the coordination of the movement of the body links. If the abilities of the gymnast are sufficient, success in performing exercises on a high technical level is acquired. In such a case the data obtained by the recording of the body movement in the development of the skill reflect the regularities in the axquisition of the exercise technique. The purpose of the present study was to analyze different stages during the development of the skill in performing the long underswing upstart on the horizontal bar. Verf.-Referat
