Clinical InvestigationHypertensionThe influence of short and long duration on the blood pressure response to an acute bout of dynamic exercise

Subjects
Volunteers were 45 men between the ages of 18 and 55 years with high normal to stage 1 HTN (systolic BP [SBP] ≥130 and <160 mm Hg and/or diastolic BP [DBP] ≥85 and <100 mm Hg). Other than high BP, all subjects were in good health without evidence of cardiovascular disease, diabetes mellitus, asthma, thyroid dysfunction, pancreatitis, cancer, infection/inflammation, or acute illness of any sort. They were nonsmokers and had no physical limitations that precluded exercise. Subjects completed an
Subjects
Study participants (N = 45) were white men with a mean age of 43.4 ± 1.5 years, an orientation ambulatory awake BP of 144.6 ± 1.6/85.2 ± 1.1 mm Hg, and an experimental baseline stabilization period BP of 126.4 ± 1.0/86.8 ± 0.7 mm Hg (Table I). Subjects were overweight and had below average physical fitness for men of their age.28 Nearly half (46.0%) of the men reported a family history of HTN, and 5 men in the LITE and MOD groups discontinued antihypertensive or hyperlipidemic medications or
Discussion
We compared the effects of SHORT- and LONG-duration, endurance exercise on PEH using a parallel study design among 2 different groups of white, middle-aged overweight men with high normal to stage 1 HTN. The new and important findings from this investigation are that SHORT- and LONG-duration, lower intensity exercise reduced SBP by approximately 4 to 6 mm Hg for the remainder of the awake hours compared with the no-exercise days. The DBP-lowering capacities of SHORT-duration exercise tended to
