exercise routines to provide greater reduction in blood pressure. Our purpose was to compare walking and stretching exercise programs in people with moderately elevated blood pressure. A recent meta-analysis of stretching programs 13 indicates similar reduction in systolic blood pressure (ie, −3.9 mm

Systolic time intervals (STI) were measured before and after exercise in 18 diabetic adolescents (D) and 18 age- and sex-matched nondiabetic controls (C). At similar heart rates, pre-exercise pre-ejection period (PEP) and left ventricular ejection time (LVET) were significantly shorter in D compared to C (p<0.05). There was no difference between the two groups in the PEP/LVET ratio. Following exercise there were no differences in STIs between groups. However, the change in PEP and LVET from pre- to postexercise was significantly less in D compared to C (delta PEP 38 vs. 53±3 msec, p<0.01; delta LVET 120 vs. 134±4 msec, p<0.05). These data suggest a hypercontractile state at rest in D and a blunted response to exercise when compared to C. This study provides data that may be relevant to the early identification of individuals at risk for premature diabetic cardiomyopathy.

An elderly patient population was used to investigate whether an acute bout of aerobic exercise (AE) would reduce systolic blood pressure (SBP) to a greater extent than would a bout of weight lifting (WL). SBPs were studied in the context of a laboratory Stressor as well as during activities of daily living using ambulatory monitoring devices (AMBPs). Patients participated in a laboratory Stressor and were monitored via AMBP for 8 hr. SBPs were lower for up to 5 hr postexercise for the AE treatment only. In addition, in comparison to no-exercise control data, baseline SBP was lower for the AE group than the WL group prior to the Stressor. Subjects in the AE condition also tended to have lower SBP responses following exercise than patients in the WL group, although these differences did not reach a conventional level of statistical significance. These data provide evidence that single bouts of AE, but not WL, may lower SBP in elderly patients, even for those who have compromised function due to osteoarthritis of the knee.

The purpose of this study was to examine the cardiovascular responses to water treadmill walking at 2.0 mph (3.2 km/hr), 2.5 mph (4.0 km/hr), and 3.0 mph (4.8 km/hr) in older adults. Responses to water treadmill walking in 92 °F (33 °C) water were compared with responses to land treadmill walking at 70 °F (21 °C) ambient temperature. After an accommodation period, participants performed 5-min bouts of walking at each speed on 2 occasions. Oxygen consumption (VO2), heart rate (HR), systolic blood pressure (SBP), and rating of perceived exertion (RPE) were significantly higher during therapeutic water treadmill walking than during land treadmill walking. Furthermore, VO2, HR, and RPE measures significantly increased with each speed increase during both land and water treadmill walking. SBP significantly increased with each speed during water treadmill walking but not land treadmill walking. Thus, it is imperative to monitor HR and blood pressure for safety during this mode of activity for older adults.

physical activity and blood pressure in children is less clear. Some studies have shown no relationship ( 6 , 18 ), whereas others have shown inverse relationships with systolic blood pressure ( 5 , 8 ), diastolic blood pressure ( 11 , 19 ), or both ( 21 , 24 , 34 ). Furthermore, despite the significant

The aging process can lead to changes in arterial stiffness, contributing to an increased left ventricular afterload via increases in the pulsatile components of systolic blood pressure (BP; Kingwell, 2002 ). Interestingly, the prevalence of this phenomenon seems to be higher among older women
