Does a combined exercise training program improve hemodynamic variables at rest and during exercise in young obese prehypertensive men?
A 12-week combined aerobic and resistance exercise training program significantly reduces resting and exercise systolic blood pressure and myocardial oxygen demand in young obese prehypertensive men.
Effect estimate: 4.3% improvement
p-value: p=<0.05
BACKGROUND: Regular exercise is an effective intervention to yield health-related benefits, though an optimal dosage and its ability to improve hemodynamics at rest and during exercise are yet to be established. Therefore, this study aimed to assess the effects of a combined (aerobic and resistance) exercise training program on hemodynamic variables at rest and during exercise in young obese prehypertensive men. METHODS: Twenty obese prehypertensive men (age: 20±1.2 years) were randomly assigned to either the combined exercise training group (CBT, N.=10), or the control group (CON, N.=10). The CBT underwent a supervised combined exercise training program incorporating four 60-min sessions per week over 12 weeks, whereas the CON remained in habitual activities. We assessed BP, peak oxygen consumption (V̇O2peak), body composition, muscular strength, and hemodynamic responses to incremental exercise at baseline and post intervention. RESULTS: The study revealed significant improvements in resting systolic blood pressure (SBP) of 4.3% (P2peak by 18.2% (P<0.01), upper body muscle strength by 15.1% (P<0.01), and reduced body fat (P<0.01). CONCLUSIONS: The CBT is effective in reducing SBP and myocardial oxygen demand at rest and during exercise. It can also improve cardiorespiratory fitness, muscular strength, and reduce body fat; especially in terms of abdominal obesity. Thus, we suggest the use of the CBT program for the prevention of future hypertension in young obese prehypertensive men.
Phoemsapthawee et al. (Mon,) conducted a rct in obese prehypertension (n=20). Combined exercise training program vs. habitual activities was evaluated on resting systolic blood pressure (SBP) (4.3% improvement, p=<0.05). A 12-week combined exercise training program significantly reduced resting systolic blood pressure by 4.3% (P<0.05) in young obese prehypertensive men.
