JEPonline 2014;17(1):40-49. The purpose of the present study was to compare the blood pressure (BP) as well as the autonomic responses during different types of abdominal exercises in 30 subjects (age 18 to 25 yrs of age) who performed an exercise session consisting of 3 types of abdominal exercises (straight partial sit-up - SPSU, oblique partial situp – OPSU, and lying hip flexion - LHF), 3 sets, 15 to 20 repetitions, and a control session with the identical experimental procedures but without exercise. Brachial BP was measured before, during, and after intervention at 5, 10, and 20 min. Heart rate variability (HRV) was assessed at baseline, during abdominal exercises, and in the postintervention periods. Compared with baseline, systolic BP increased immediately after the SPSU, OPSU, and LHF exercises (P<0.001). Systolic BP and diastolic BP were not altered during the control session. In both sessions, BP was not affected in the post-intervention periods. In comparison with the control session, systolic BP increased 7.6%, 5.8%, and 7.6% after the SPSU, OPSU, and LHF exercises, respectively (P<0.001). Diastolic BP did not differ between sessions. After the LHF exercise, HRV was significantly decreased (P<0.05) when compared to the control session. In healthy subjects, abdominal exercises at low-to-moderate intensities induced small increases in BP, which was accompanied by a discrete decrease in HRV.
