Sažetak
The basic data for this investigation was gathered in 1973. from the tests of 191 alpine skiers aged 12 (+/- 6 months). Up to the time of testing the subjects had spent at least 2 years in training alpine skiing in either ski clubs or selection centers. The sample of measuring instruments was made up of 3 situational ski tests (straight vertical, irregular vertical and coordination test - 8), slalom, technique assessed by judges and "jugo" points of categorization for junior skiers.
In order to establish the metric characteristics of composite tests (all tests except "jugo" points) the algorythm RTT MARK was used. It was developed at the Faculty of Physical Education in Zagreb and along with the classic reliability measures it also calculates the representativity measures as well as generalizibility and homogeneity of composite test. Two comparative component analyses determined the latent structure of the tests used.
Except for the coordination test on snow (SKOORD), all the other tests have very good metric characteristics. They can be therefore be used to form the criterion variable in studies of relation between achievement in alpine skiing and various subsystems of psychosomatic status of alpine skiers. The component analysis yielded only one latent dimension, named as alpine ski motor ability.
