Title of master thesis Effect of ski-mountaineering equipment on energy expenditure of skiing. Work objectives The aim of this study was to determine the effect of weight ski equipment energy performance when walking on snow. Methods The study included 6 skialpinists a mean age of 30 ± 5.5 years. Energy intensity was measured on the basis of breathe oxygen (VO2) and exhaled (VCO2). The measurements were used 3 types of ski-hiking equipment (light - medium x 3160 g - 7754 g x heavy - 9600 g). Each test first completed section in a time of 6 minutes flat terrain (0ř), after which he immediately set out to climb the 360 m long route at an angle (20ř). These two sections (0ř and 20ř) graduated in random order for each type of equipment and at a constant speed of 1 m·s-1 . Results The results show that energy intensity decreases significantly when using ultralight ski equipment. We found that the climb at an angle of 20ř is the difference in oxygen consumption (VO2) between moderate and light equipment 9.6% between heavy and light equipment 17.7% and medium-heavy and heavy equipment 7,4%. The average VO2 test with light equipment was 44.4 ± 3.7 ml·kg-1 ·min-1 , with moderate equipment 48.7 ± 5.6 ml·kg- 1 ·min-1 and heavy equipment 52.2 ± 4.8 ml·kg-1 ·min-1 . At 0ř inclination and moderate use of heavy...
