Factor analysis of training load determining a sport performance of a race walker for 35 kilometres

The work refers to the groups of training indicators which determine a sport performance at 35 kilometer walking race. We used an exploration factor analysis to reduce the indicators into the sets of some factors. As we wanted to judge its suitability KMO statistics and Bartlet test of sphericity (BTS) were adopted for the test. We also employed ortogonal rotation Quartimax to minimize the number of the factors. The estimation based on the method of the main components is explained with help of three clusters of training indicators with the variability of 65,38 %. The cluster of the first set of factors (33,21 %) was made by indicators of intensive tempo walking speed (STI 101), extensive specific endurance (STI 104), intensive and extensive tempo endurance (STI 105 a STI 106) and also aerobic endurance (STI 107). The second set of factors (18,67 %) was created by extensive tempo walking speed (STI 102) and intensive specific endurance (STI 103). It was possible to define the third factor (13,50 %) STI 108 from the indicators of aerobic walking limit. All the factors are saturated positively by individual indexes. Theresults refer to an intraindividual structure of training indicators which determine a sport performance of a race walker at a new athletic discipline. The suggested model of factors can be used while planning the periodization of an volume and intensity of a training loud. We will start from the objective categories of training means which determine a sport performance of walkers at a walking race for 35 kilometers at the sport limit 2:34:00.
