RESUMO:

INTRODUCTION: The sedentary behavior (SB) is associated to an increased risk of metabolic syndrome, while moderate-vigorous physical activity reduces the risk of this syndrome. Thus, different strategies should be investigated in order to prevent the SB-related cardiometabolic risk. AIM: To assess the effect of a single session of high-intensity interval exercise (HIIE) and regular breaking up of SB during the day on blood pressure, glucose and tryglicerides in young overweight adults. METHODS: In a randomized controlled trial using a crossover trial 22 overweight and inactive adults (10 males; 25.5 ± 3 years; % body fat 34.5 ± 6; 5.017 ± 1.960 steps/day) were submitted to three experimetal sessions during 9.5 hours. The order of the session was randomized and separated by one-week interval: i) SB session: high SB during the day (< 1.500 steps/day); ii) EX+SB session: a single session of HIIE followed by a SB during the day; iii) ACTIVE session: regular breaking up of SB during the day; i.e., 5 min of light walking every 30 min. The participants received four standardized meals during the day in each session: baseline (breakfast), after 3 h (in the morning), after 5 h (lunch), and after 8:45 h (in the afternooon). Glucose and blood pressure were measured before and after 1 h after each meal, and 2 h after the lunch. Tryglicerides was measured at baseline and 2 and 3 h after lunch. Area under the curve (AUC) was calculated for each cardiometabolic parameter. Generalized estimating equation was used to compare the cardiometabolic sessions among the sessions and the statistical significance was set at 5%. RESULTS: No statistical differences were observed among the experimental sessions (p ≥ 0.316).  CONCLUSION: A single session of intense exercise or regular breaking up of SB using light walking does not reduce blood pressure and postprandial levels of glucose and tryglicerides in young overweigth and inactive adults.
