Step treadmill exercise training and blood pressure reduction in women with mild hypertension.
Stepping as an exercise modality has gained increasing popularity. The step treadmill is an exercise machine which simulates actual stair-climbing. The purpose of this study was to determine the effectiveness of a 16-week supervised aerobic step treadmill exercise training protocol in reducing resting blood pressure in women with unmedicated mild hypertension. During the training protocol, subjects exercised during a self-selected appointment three times a week on the step treadmill, increasing from 20 minutes up to 60 minutes per session, at a target heart rate corresponding to 70-80% heart rate reserve for 16 weeks. Utilizing paired t-test analysis, mean resting systolic blood pressure decreased from 142.2 +/- 9.1 to 132.7 +/- 8.2 mm Hg (p < .01) and mean resting diastolic blood pressure decreased from 93 +/- 4.9 to 87.4 +/- 5.4 mm Hg (p < .01) during the 16-week protocol. Mean maximal oxygen uptake was significantly increased, whereas mean body weight did not change significantly over the 16-week period. Large scale trials are needed to further delineate the effectiveness of stepping as a health care intervention in adults with unmedicated mild hypertension, especially in women.
