THE INFLUENCE OF BODY DIMENSIONS ON SUCCESS IN YOUNGER CATEGORIES IN ALPINE SKIING

Blaž Lešnik & Milan Žvan

The goal of the research was to determine the level of relation between body dimensions and competitive success in alpine skiing. There were 28 competitors included in the research, aged 11-12 years, who were competing in the category of younger boys for the Children Grand Prize of Slovenian Ski Association (Mercator Cup in 2012/13). The following 6 body dimension parameters were used in the research: average knee circumference (AKC), average thigh circumference (ATC), body weight (BW), body height (BH), body fat percentage (BF%) and body mass index (BMI). The data was measured with a device for measuring anthropometric dimensions (3D Body Scan). The criterion variables (competitive success) were determined on the base of total amount of points gained in the Mercator Cup (PTS). The analysis showed that the influence of body variables (BV) on the success of younger categories in alpine skiing (PTS) is statistically significant (BV/PTS; R=0.654). The body height (BH; r=0.5) and the body weight parameter (BW; r=0.471) has the greatest influence on the competitive success, while the body fat percentage is the only parameter which doesn't represent so much statistically significant influence. From the collected data big differences in physical development of measured boys are evident, as they are in the pre-puberty development phase and therefore some of them physically develop earlier, while others are physically developed later.
