The purpose of this study was to determine the effects of 10 weeks high bench and low bench step aerobics on health-related physical fitness. METHODS: Twenty-four college healthy female students volunteered to participate in this study. They were randomly assigned to one of two treatment groups: a high bench step aerobic group (bench height 25 cm), and a low bench step aerobic group (bench height 15 cm). The two experimental groups received a regular schedule on high bench step aerobics and low bench step aerobics training (55 minutes each time, three times a week) for ten weeks. All subjects signed an informed consent form prior to participation in the training. Before and after the training, health-related physical fitness of all subjects was evaluated. A dependent t test was used to compare the differences between pretest and posttest of both groups. RESULTS: We found significant effects of high bench step aerobic training on decreases in percentage of body fat (P<0.05), increases in muscle fitness (P<0.05), flexibility and cardiovascular fitness (P<0.05), at the end of the study, as compared to the onset. There were no statistically significant differences (p>0.05) found in almost all the health-related physical fitness variables assessed, except for the flexibility and cardiovascular fitness indexes (P<0.05), between the two trials for the low bench step aerobic group. CONCLUSION: The results of this study appear to suggest that high bench step aerobics is a very good exercise to increase the health-related physical fitness and improving physical health. It remains uncertain whether low bench step aerobics can achieve the same benefit of total physical fitness as those of high bench step aerobics, and needs to be investigated further.
