Ruzdija Kalach, Seryozha Gontarev, Zikica Tasevski

The sample of 102 male students-boxers from Macedonia, aged 18-33 years, applied 21 motor test to determine the diagnostic factor validity as a metric feature of the tests applied. The validity of the tests is determined by factor analysis under the component model. The Intercorrelation matrix of motor tests is factorized with Hotteling method of main components, and the number of significant principal components is determined by the Guttman-Kaiser criteria, according to which, all characteristic roots equal or greater than 1 are considered. Based on the given results it can be concluded that most of the tests applied have satisfactory factor validity and may be applied in the diagnosis of motor skills of boxers. As a pretext for diagnosing motor skills the following reduced battery of tests is recommended: eights by leaning (coordination assessment), standing on one leg on the balance beam at length with eyes closed (to assess the balance), tapping a hand in the sagittal area (to assess the frequency of movements), deep stretching in sitting position (assessment of flexibility), raising the trunk in 30 seconds (the assessment of power), dumping medical ball(1kg.) from a position on back (to assess the explosive power) and shooting with a short stick (assessment of precision).
