AB [EN] Sedentary behaviors, those that involve sitting and low levels of energy expenditure, havebeen associated with several adverse cardiometabolic effects. This study evaluated the chroniceffects of a combined circuit weight interval training (CWIT) on physical fitness, quality of life, andheart rate variability (HRV), and compared the effects of CWIT-induced autonomic adaptations ondifferent postures in adult sedentary workers. Twenty-seven sedentary workers (age 36.9 ± 9.2 yearsold, 13 men and 14 women) were divided into two groups: control, who continued their sedentarybehavior, and experimental, who were submitted to a CWIT for 12 weeks, completing two ~40 minsessions per week. Monitoring of 8th, 16th, and 24th sessions revealed a moderate training loadduring sessions. Participants exhibited an improved aerobic capacity (VO2max, 34.03 ± 5.36 vs.36.45 ± 6.05 mL/kg/min, p < 0.05) and flexibility (22.6 ± 11.4 vs. 25.3 ± 10.1 cm, p < 0.05) after thetraining period. In addition, they showed greater quality of life scores. However, the CWIT didnot change body composition. Interestingly, more HRV parameters were improved in the seatedposition. The CWIT used in the current study was associated with improvements in several fitnessand quality of life parameters, as well as in cardiac autonomic control of HR in adult sedentaryworkers. Examination of different body positions when evaluating changes in HRV appears to be arelevant aspect to be considered in further studies. Future randomized controlled trials (RCTs) withlarger samples of both sexes should confirm these promising results.
