Energy expenditure and intensity of HIIT bodywork® session

Abstract

Several programs using total body weight exercise methods have been applied in several populations especially using HIIT. The present study assessed the oxygen consumption, heart rate, and energy expenditure of a HIIT body work ® session. Methods: Twelve male participants performed 20 minutes of a HIIT body work, consisting of 20 sets of 30 seconds of stimulation in all-out intensity, followed by 30 seconds of passive recovery. Five cycles were performed for each exercise (jumping jack, burpee, mountain climb, and squat jump). Results: The mean VO2 of the session was 34 ± 7 ml.kg.min-1 (80.35% of the VO2 peak obtained in the session). The energy expenditure of the session was 251±27 kcal (13±1 kcal.min-1) and 39 ± 8 kcal (75±1 kcal.min-1) during the recovery time. The heart rate values were 160±18 bpm (91% of the peak HR of the session) and 125±22 bpm (71%) in recovery. In addition, significant differences (p<0.05) in maximal VO2 were found between jumping jack, mountain climber, burpee and squat jump. Conclusion: Based on the present data, a HIIT bodywork ® session presented energy expenditure as a typical high-intensity exercise profile.

Energy Expenditure in Hiit Whole Body Associated With Electromyostimulation

“…The main findings of the present study are related to the influence of WB-EMS in promoting an increase in oxygen uptake, lactate concentration and energy expenditure without promoting significant changes, related to control situation, in psychophysiological indicators of monitoring in physical training sessions. To our knowledge, there are few studies that investigated the energy expenditure in exercise sessions that used only body weight 21,22 as well as the use of WB-EMS. 15 In this study, we demonstrated that the use of WB-EMS intensified the total and relative energy expenditure compared to the control condition, (Figure 1) however, it is worth mentioning that although different, the differences between the sessions corresponded to only 6.14± 5.61%.…”

“…min -1 , HIIT+WB-EMS: 11.76± 1.85 Kcal.min -1 ) herein are not so different from other modalities that use high intensity training [23][24][25][26] with values comprised between 7.5 to 9.7 Kcal.min -1 . 21,22,[23][24][25][26][27] To the best of our knowledge there are few studies available on literature 15,23 evaluating energy expenditure and WB-EMS. BOCCIA et al 23 performed two training sessions of 15 minutes based on isometric intermittent contraction (6 seconds of contraction interspersed by 4 seconds of rest) and found energy expenditure of 470 ± 71 kcal.h -1 and 438 ± 61 kcal.h -1 .…”

“…The MET presented in the present study in both conditions (HIIT and HIIT + WB-EMS), although different from each other, were similar to other studies that used high-intensity training using body weight. 22 . It is worth mentioning that studies 24,30 indicate that exercises with values above 6 METS are considered to be intense.…”

“…It is worth mentioning that studies 24,30 indicate that exercises with values above 6 METS are considered to be intense. Other intensity indicators popularly used in high-intensity exercise sessions using body weight are HR 10,22 and lactate concentration 10,31 . Our data indicated that both sessions corresponded to 89% of maximum HR and 11 to 12mmol.L -1 of lactate, values similar to other studies for both HR and lactate concentration that used HIIT with body weight.…”
