Key words: key components, external mechanical work, general fitness, centroidal method, golf.
The purpose of the present paper was to consider centroidal method of key components in estimation of general fitness in golf.
Results of any test of motor activity are obviously a consequence of the information-energy exchange taking place in a body, characterized by the volume, power and effectiveness. Therefore it seems acute to subject test results in the form of energy expenses and information spent while performing this or that motor act.
Results of general fitness tests of pupils of specialized children sport schools of Olympic reserve "Moscow golf school" for 2009, 2010, 2011 (14-17-aged young girls and boys, 20 and 41 persons correspondingly) were used to analyze by means of key components. External mechanical work on displacement of common centre of gravity in other general fitness tests were calculated analytically, in assumption that the length of units and body weight did not change at tests.
Therefore, analysis of the total variance and volume of external mechanical work, performed while performing general fitness tests by orthographic basisfrom key components promotes allocation of the percentage contribution of units and comprising it muscle groups. The results of such an analysis facilitate allocation of priorities in development of muscle groups to achieve high results in general fitness tests. In order to improve sports results in golf priority in development of these or those muscle groups is to be determined in accordance with the data of component analysis of total variance and volume of work in view of trends (mutual correlation) of general fitness test results with the level of sportsmanship of golf-players.
