Differences among the original and obtained clusters of athletes from different sports background

The aim of the study was to determine whether all elite athletes coming from the same energetic group of sports showed similar response of the functional parameters to the physical load. The sample comprised 102 elite athletes divided into three groups: aerobic, mixed and anaerobic (original clusters). The testing encompassed morphological, motor and functional parameters (VO2max exhaustion treadmill test). Discriminant analysis of the original clusters, kmeans clustering, and discriminant analysis of the obtained clusters were performed. Original clusters did differ from each other (signifi cant morphology and aerobic capacity functions) but cluster analysis showed mixing of the subjects between obtained clusters and pointed to the entities that differed from others in their group but still performed well in competitions. It meant that the years of specifi c training did not alter in a large extent, some of their cardio-respiratory characteristic, which could be explained by heritage. The evaluation of the athletes made strictly according to the results of functional testing should be avoided because in some athletes who developed compensatory mechanisms it could underestimate their potential.
