Abstract:
The purpose of this study was to evaluate and compare the effort intensity during two step classes [choreographed (CS) and athletic (AS)]. The 8 participants (female, 21.3 ± 1.1 years) were submitted to two 45 minute sessions, with the step at 15cm and musical cadence of 132bpm, 48h interval between sessions. Effort intensity was assessed by heart rate (HR) monitoring. The HR reserve was calculated and the zones of intensity determined (ACSM, 2011). The Rated Perceived Exertion (PSE - Borg scale) was also evaluated. The mean HR in CS and AS classes was 157 ± 18.3bpm and 158.1 ± 7.1bpm, respectively, translated into a mean intensity of 69.2 ± 13.5 (CS) and 69.7 ± 6.2 (AS) of HR reserve, without significant differences between the two step modalities (p> 0.73). However, in AS class, the participants spent 70 ± 8.8% (p> 0.05). of the time in vigorous activity, while in CS they passed 50 ± 10.3% (p> 0.05). No significant differences were found regarding the time spent in other training zones, between modalities. In AS class (16.67 ± 1), the PSE was significantly higher than in CS class (15.44 ± 0.73). Both modalities allow to practice moderate to vigorous physical exercise, in agreement with the ACSM’s (2011) recommendations.
