ABSTRACTThe purpose of this study was to determine the physiological characteristics of aerobic dance instructors. A cross section of 35 aerobic dance instructors who had taught continuously for at least one year volunteered to take part in the study. The instructors taught an average of 5.6 classes per week, 4.2 days per week, for 3.9 years. Maximum aerobic power (JOURNAL/jscr/04.02/00124278-199002000-00006/ENTITY_OV0312/v/2017-07-20T235110Z/r/image-pngO2 max) was determined from a maximal treadmill test, body composition was determined by hydrostatic weighing, and blood samples were collected at rest and analysed for homeglobin and hematocrit. The instructors were placed into two groups for comparative purposes: age < 30 years (N = 18) and age > 30 years (N = 17). The younger age group had a significantly (p < 0.05) higher heart rate max (188.8 vs. 175.24 beats·min−1), a greater JOURNAL/jscr/04.02/00124278-199002000-00006/ENTITY_OV0312/v/2017-07-20T235110Z/r/image-pngO2 max expressed in ml·kg·min−1 (52.5 vs. 46.0) and L·min−1. (2.8 vs. 2.4 L·min−1), and a higher JOURNAL/jscr/04.02/00124278-199002000-00006/ENTITY_OV0312/v/2017-07-20T235110Z/r/image-pngE max (82.5 vs. 69.5 L·min−1). No significant differences were found for height (160.8 vs. 160.7 cm), weight (54.2 vs. 53.4 kg), lean body mass (45.1 vs. 43.5 kg), percent fat (16.6 vs. 18.1 percent), resting heart rate (61.7 vs. 61.1 beats·min−1, hemoglobin (14.8 vs. 14.4 g/dl), or hematocrit (41.6 vs. 40.8 percent). The younger age group was more active teaching, 6.3 vs. 4.8 classes per week, 4.7 vs. 3.9 days per week, and had less teaching experience, 3.3 vs. 4.7 years. These results suggest that aerobic dance instructors have physiological profiles that are superior to those reported for sendentary female and are comparable to the profiles of other aerobically trained females runners and joggers.
