Abstract

The purpose of this study was to determine the effects of step height and arm involvement on oxygen consumption (VO2), VO2 as a percentage of VO2max, and energy cost during step aerobics. VO2 and Respiratory Exchange Ratio were measured as 12 subjects completed 6 experimental conditions, which consisted of 3 step heights, 4, 6, and 8 in., and 2 arm conditions, with and without arms. Measured VO2 values were also analyzed as a percentage of maximal oxygen consumption to determine if subjects were within the ACSM recommended range of 50% to 85% of VO2max. ANOVAs revealed significant differences in each variable for step height and arm involvement. The 4 in. step height without arms was the only condition not within the recommended range. Results showed that increasing step height and the addition of arm involvement increased VO2, VO2 as a percentage of VO2max, and energy cost.
