RPM® is a choreographed indoor cycling (IC) class characterized as a high intensity and energy expenditure (EE) exercise. However, there is not enough information about this subject in the literature. Therefore, the objective of this study was to determine the cardiorrespiratory and metabolic responses during an IC class. Seven IC instructors (age 25.1±2.5years; weight 82.7±10.7kg; height 177.3±4.2cm; percent body fat 14.6 ± 4.8 %) participated in the study. The individuals were submitted to a maximal incremental load test (IT) on a cycle ergometer. After, a IC class was monitored. Descriptive statistics were reported as mean±SD. To verify significant differences in physiological indexes among IT and IC, student’s t-test for dependent samples was used. The level of significance was set at p < 0.05. The maximal heart rate, mean heart rate, maximal oxygen consumption, mean oxygen consumption and blood lactate concentration of IC related to the maximal values of IT were 97.1±4.6%; 81.7±6.4%; 99.1±2.6%; 68.6±5.6 e 72.8±34.0%, respectively. The total energy expenditure during the IC was 725.1±116.0kcal. In conclusion, the IC class presented a high EE as a result of the exercise intensity confirmed by the measured physiological indexes, which reported to be adequate to the improvement of the aerobic fitness.Downloads
