Resumen de Fit Women Are Not Able to Use the Whole Aerobic Capacity During Aerobic Dance

This study compared the aerobic capacity during maximal aerobic dance and treadmill running in fit women. Thirteen well-trained female aerobic dance instructors aged 30 ± 8.17 years (mean ± SD) exercised to exhaustion by running on a treadmill for measurement of maximal oxygen uptake ([latin capital V with dot above]O2max) and peak heart rate (HRpeak). Additionally, all subjects performed aerobic dancing until exhaustion after a choreographed videotaped routine trying to reach the same HRpeak as during maximal running. The p value for statistical significance between running and aerobic dance was set to <=0.05. The results (mean ± SD) showed a lower [latin capital V with dot above]O2max in aerobic dance (52.2 ± 4.02 ml·kg-1·min-1) compared with treadmill running (55.9 ± 5.03 ml·kg-1·min-1) (p = 0.0003). Further, the mean ± SD HRpeak was 182 ± 9.15b·min-1 in aerobic dance and 192 ± 9.62 b·min-1 in treadmill running, giving no difference in oxygen pulse between the 2 exercise forms (p = 0.32). There was no difference in peak ventilation (aerobic dance: 108 ± 10.81 L·min-1 vs. running: 113 ± 11.49 L·min-1). In conclusion, aerobic dance does not seem to be able to use the whole aerobic capacity as in running. For well endurance-trained women, this may result in a lower total workload at maximal intensities. Aerobic dance may therefore not be as suitable as running during maximal intensities in well-trained females.
