Perfil fisiológico de uma aula de body step？

the aim of the present study was to determine the physiological profile of a body step？ (bs) class by heart rate (hr) average and blood lactate concentration ([la]). eleven women (25 ± 4 years; 59.5 ± 5.5 kg; 164.2 ± 7.5 cm; 22.8 ± 2.6% body fat) practitioners of this class underwent two interventions: a submaximal step test and a bs class. the hrpeak and hraverage found during the class were 182 ± 9 and 142 ± 12 bpm, respectively. the estimated total energy expenditure of the class was 480.7 ± 79.3 kcal. related to [la], the participants remained at 58.3% of the music in the heavy domain, 25% in the moderate and 16.7% in the severe domain. thus, it can be concluded that the bs class showed high intensity, confirmed by the measured physiological indexes, which are adequate to the improvement of the aerobic fitness.
