Summary Metabolic syndrome ( M et S ) is a cluster of risk factors in individuals with high risk of diabetes and heart disease. Resistance training ( RT ) has been proposed to be a safe, effective and worthwhile method for the prevention and treatment of metabolic and cardiovascular diseases. However, no study has analysed the acute response of blood pressure ( BP ) and autonomic control of heart rate ( HR ) after a RT session in female patients with M et S . The aim of the present study was to analyse the response of laboratory assessed and ambulatory BP and cardiac autonomic modulation after a RT session in women with M et S . Nine women without M et S (35·0 ± 6·7 years) and 10 women with MetS (34·1 ± 9·4 years) completed one experimental exercise session and a control session. Laboratory BP , heart rate variability ( HRV ) and ambulatory BP of each subject were measured at rest, over 60 min, and for 24 h after the end of the sessions, respectively. There was a significant reduction in systolic blood pressure ( SBP ), night time diastolic blood pressure ( DBP ) and mean blood pressure ( MBP ) only for women with M et S , for all periods after the RT session when compared with the control session ( P <0·05). Significantly lower laboratory values of SBP and DBP (10, 30 and 40 min postexercise) and MBP (10, 40 and 50 min postexercise) were observed in women with M et S ( P <0·05). Patients with M et S exhibited significant lower basal HRV and a lower autonomic responsiveness during the 60 min of acute recovery. These results confirmed that an acute session of resistance exercise induced a lower BP during day time and sleeping hours in women with M et S that may offer a cardio‐protective effect. Women with M et S exhibited an impaired autonomic modulation at rest and a lower acute autonomic responsiveness to a RT session. The dissociation between BP and HRV responses suggests that other factors than autonomic control could be involved in the hypotensive effect of a RT session in M et S patients.
