Key result
Combined endurance and resistance exercise, regardless of order, significantly attenuated postexercise increases in blood pressure compared to a resting control session (p≤0.05).
Why the study?
Does the order of endurance and resistance exercise affect postexercise blood pressure and hemodynamics in hypertensive women?
Does the order of endurance and resistance exercise affect postexercise blood pressure and hemodynamics in hypertensive women?
Combined endurance and resistance exercise attenuates postexercise blood pressure increases in hypertensive women, regardless of the order in which the exercises are performed.
Combined exercise may attenuate postexercise BP rises in hypertensive women; hypothesis-generating for sequencing and needs larger trials before practice change.
The study aims to evaluate the effects of the order of endurance and resistance exercises on postexercise blood pressure (BP) and hemodynamics in hypertensive women. Nineteen hypertensive women underwent 3 sessions: control (50 minutes rest), endurance (50-60% of heart rate reserve) followed by resistance exercise (50% of 1 repetition maximum) (E + R), and resistance followed by endurance exercise (R + E). Before and 30 minutes after each session, BP, peripheral vascular resistance, cardiac output, stroke volume, and heart rate were measured. Postexercise increases in systolic (E + R: +1 ± 3 mm Hg and R + E: +3 ± 3 mm Hg), diastolic (E + R: +3 ± 1 mm Hg and R + E: +3 ± 2 mm Hg), and mean BP (E + R: +3 ± 1 mm Hg and R + E: +3 ± 2 mm Hg) were significantly lower after the exercise sessions compared with the control session (p ≤ 0.05). The exercise sessions abolished the increases in peripheral vascular resistance (E + R: +0.00 ± 0.04 mm Hg·min·L and R + E: +0.05 ± 0.05 mm Hg·min·L) and the decreases in cardiac output (E + R: +0.04 ± 0.28 L·min and R + E: -0.26 ± 0.28 L·min) observed after the control session (p ≤ 0.05). After the exercise sessions, stroke volume decreased (E + R: -14 ± 3 ml and R + E: -9 ± 4 ml) and heart rate increased (E + R: +5 ± 1 b·min and R + E: +4 ± 1 b·min) in comparison with the control session (p ≤ 0.05). For all the variables, there were no significant differences between the exercise sessions. Regardless of the order of endurance and resistance exercises, combined exercise sessions abolished increases in BP observed in a control condition due to a reduction in peripheral vascular resistance and increases in cardiac output. Thus, combined exercises should be prescribed to individuals with hypertension to control their BP, regardless of the order they are accomplished.

Menêses et al. (2014) studied Hypertension (n=19). Combined endurance and resistance exercise vs. Control (50 minutes rest) was evaluated on Postexercise blood pressure and hemodynamics (p=≤0.05). Combined endurance and resistance exercise, regardless of order, significantly attenuated postexercise increases in blood pressure compared to a resting control session (p≤0.05).
