The purpose of this study was to investigate the effects of 10 weeks of step aerobics training on anaerobic performance of men and women. College-age volunteers (64 women and 54 men) were divided into step aerobics (33 women, 27 men) and control (31 women, 27 men) groups. Before and after the 10-week period, the subjects' body composition, muscular strength, Wingate anaerobic performance, and vertical jump anaerobic performance were determined. The step aerobics group participated in step aerobics sessions of 50 minutes per day, 3 days per week for 10 weeks, at 60-80% of their heart rate reserve. Results of 2 x 2 analysis of covariance with repeated measures indicated significant sex differences in percentage body fat, lean body mass, muscular strength, and in all of the measured indices of the Wingate Anaerobic Test. The step aerobics group showed significant improvement only in mean power relative to body weight compared with the control group and women showed significant improvement only in anaerobic power of vertical jump when compared with men. It can be concluded that 10 weeks of step aerobics was not effective in improving all of the measured anaerobic indices in men and women.
