An exercise training combined with dietary program for patients with hypertension.

ABSTRACT

A controlled clinical trial was conducted to determine whether combined exercise training and diet alone reduce blood pressure (BP), body weight and body mass index (BMI) in three weeks. Twenty eight patients with diastolic BP < or = 110 mmHg were assigned to a hypertensive group and another 28 subjects with diastolic BP < or = 90 mmHg were subjected to the same intervention as control group (normotensive group). Exercise training and diet reduced diastolic BP by 24.7 mmHg and systolic BP by 32.8 mmHg in hypertensive group. There was a mean decreased of 5.3 mmHg in the diastolic BP in the normotensive group (P < 0.001). The systolic BP decreased only minimally. The weight loss ranged from 1 kg to 3 kg in hypertensive and 1 kg to 2 kg in the normotensive group. The mean weight loss was 1.6 kg (0.7) in hypertensive and 1.5 kg (0.5) in the normotensive group. In both the groups the weight reduction was highly significant (P < 0.001) and moderately positive correlation was also noted with the fall of BPs. The mean fall of BMI was 0.61 kg/m2 (0.21) and 0.51 (0.2) kg/m2 in the hypertensive and normotensive groups respectively. The findings indicated that a combined exercise training and dietary program could lower BP in patients with mild to moderate hypertension, but its long-term consequences on morbidity and mortality remain to be determined.
