Article excerpt

BARCELONA -- Aerobic interval exercise training is a more effective treatment for hypertension than is moderate-intensity continuous exercise, according to a Norwegian randomized trial.

In the study, 89 patients with grade 1 or 2 hypertension who were not on medication were randomized to one of three exercise training regimens carried out three times a week for 12 weeks. The study arms consisted of supervised aerobic interval exercise with a target intensity of 90%-95% of maximum heart rate, supervised isocaloric continuous exercise at 70% of maximum, or, as a control, standard medical advice about the importance of physical activity but no supervised training.

After 12 weeks, mean 24-hour blood pressures in the aerobic interval training group had improved from a baseline of 154/94 mm Hg to 141/87 mm Hg. Their maximal oxygen uptake ([VO.sub.2max]) rose by about 15%, from 36.3 to 41.7 mL/kg a minute. Those were significantly greater improvements in blood pressure and [VO. …
