Introduction: BODYJAM is a relatively new form of aerobic dance that combines hip hop dance moves with the latest trending music. It is unique in that it progressively “layers” dance movements so that participants can regulate exercise intensity to their individual ability. Purpose: To determine the energy expenditure and relative exercise intensity during a BODYJAM class. Methods: Nineteen female (age 20.1 ± 1.14 years) subjects completed a maximal treadmill test and a 55-minute BODYJAM session. Heart rate and RPE were recorded throughout the BODYJAM session. The HRs that were recorded during the workout were inserted into individual HR/VO2 regression equations, developed from the treadmill test, to estimate VO2 and energy expenditure. Results: It was found that subjects exercised at an average of 73 ± 3.5% of %HRmax and 52 ± 6.6% of %VO2max. Energy expenditure averaged 393 ± 86.4 kcal/session and RPE during the workout averaged 11.5 ± 1.91. Conclusion: The BODYJAM session meets the standards set forth by ACSM to improve cardiorespiratory fitness and body composition and provides an upbeat alternative to traditional aerobic exercise modalities.
