Sažetak
The main purpose of this study was to define flexibility space while using different measurement procedures and to assess its susceptibility to the influence of morphological characteristics. The data were collected using a sample of 236 male students of the University of Ljubljana who were all between 21 and 22 years of age. Flexibility was measured using fifteen tasks, all requiring wide amplitudes of movement in the area of the shoulder, trunk and hip joint. The amplitudes were measured with three different procedures, using linear measures, a gravity goniometer and a classical goniometer. The data on morphological characteristics were collected by using a battery of twenty-one measures. Most of the applied measures of flexibility showed a satisfactory degree of reliability (classical and contemporary coefficients of reliability). All factor structures (direct oblimin and HG criteria for factor extraction) obtained by means of different measurement procedures were defined by latent dimensions that are topologically oriented to joints and their wider areas, and accurately defined by the action and space characteristics of movements. The different measurement procedures used on the same tasks give the same form of flexibility. It was also found that almost all the measures of the three methods were influenced by morphology (regression analysis), although the structure of flexibility was not (congruence coefficients). On the basis of the collected data, it can be stated that the flexibility measurement procedure implying the use of a gravity goniometer is the most adequate way to collect the relevant data.
