Conditionality Of Maximum Oxygen Uptake Obtained By Different Exercise Machines With Training Load Setup Using Gross Motor Skill Tests

The aim of this study was to determine the conditionality of relative maximum oxygen uptake obtained (RVO2max) by using three different exercise machines with training load setup (treadmill, cycle ergometer and Orbitrek elliptical trainer) while utilizing a gross motor skill test. In accordance with the study aim, a sample of 19 female students was used. A progressive exercise protocol was applied until the exhaustion of participants had set in. Relative maximum oxygen uptakes obtained from utilized exercise machines were set as dependent variables for a multiple regression analysis with forward algorithm of variable selection. The following gross motor skill tests were set as independent variables: side steps (MKUS), hexagon test (HEX), standing long jump (MSDM), throwing a medicine ball (MBML), number of push-ups performed until exhaustion set in (MSKL), number of sit-ups in 60 seconds (MTRB), balance on two feet with closed eyes (MBAP2Z), balance on one foot with open eyes (MBAU10), arm plate tapping (MBTAP) and foot taping (MBTAN). Results indicate statistically significant (p<0.01) and relatively strong (R2=0.65-0.92) predictive power of the selected gross motor skill variable set (additionally reduced by forward variable selection algorithm for entry into a model) and unambiguously show that a set of applied motor skill variables can be used in scientific and professional practice as a good predictor of the relative maximum oxygen uptake.
