The Effects of Cadence, Impact, and Step on Physiological Responses to Aerobic Dance Exercise

The physiological responses to aerobic dance exercise of varied impact (high, low), step (less arm movement vs. more arm movement), and cadence (124 vs. 138 beats.min-1) were investigated. Experienced, female aerobic dancers (N = 16) performed activities that combined the levels of impact and step for 3 trials of 8-min each. Dependent variables included heart rate, percentage of maximal heart rate, oxygen consumption, percentage of maximal oxygen consumption, and respiratory exchange ratio. Repeated measures analyses of variance indicated a significant Impact x Step interaction whereby oxygen consumption was greater for the high impact-less arm movement activity (jog), while the low impact-more arm movement activity (power jack) was greater for heart rate. The interaction of aerobic dance characteristics (e.g., impact, arm movement) that may alter physiological responses to aerobic dance exercise should be identified in future aerobic dance routines and studies.
