“…Additionally, of the 30 studies, only nine were randomized controlled studies using hypertensive controls. 10,12,17,19,21,22,[29][30][31] None compared exercise to a credible alternative treatment or attention/placebo. Furthermore, in two of these controlled studies,12,17 the untreated hypertensive controls exhibited significant average reductions in BP (mainly DBP) similar to their exercised counterparts.…”

Controlled trial of aerobic exercise in hypertension.

To determine the antihypertensive efficacy of aerobic exercise training in mild essential hypertension, a prospective randomized controlled trial was conducted comparing an aerobic exercise regimen to a placebo exercise regimen, with a crossover replication of the aerobic regimen in the placebo exercise group. The study took place in an outpatient research clinic in a university-affiliated Veterans Administration medical center. Twenty-seven men with untreated diastolic blood pressure (DBP) of 90-104 mm Hg were randomized to the two exercise regimens. Ten patients completed the aerobic regimen. Nine patients completed the control regimen, seven of whom subsequently entered and completed the aerobic regimen. The aerobic regimen consisted of walking, jogging, stationary bicycling, or any combination of these activities for 30 minutes, four times a week, at 65-80% maximal heart rate. The control regimen consisted of slow calisthenics and stretching for the same duration and frequency but maintaining less than 601% maximal heart rate. DBP decreased 9.6+±4.7 mm Hg in the aerobic exercise group but increased 0.8±+6.2 mm Hg in the placebo control exercise group (p=0.02). Systolic blood pressure (SBP) decreased 6.4±9.1 mm Hg in the aerobic group and increased 0.9±9.7 mm Hg in the control group (p =0.11). Subsequently, seven of the nine controls entered a treatment crossover and completed the aerobic regimen with significant reductions in both DBP (-6.1+3.2 mm Hg, p<0.01) and SBP (-8.1±5.7 mm Hg, p<0.01). BP changes were not associated with any significant changes in weight, body fat, urinary electrolytes, or resting heart rate. This randomized controlled trial provides evidence for the independent BP lowering effect of aerobic exercise in unmedicated mildly hypertensive men.

The Effect of Duration of Stretching of the Hamstring Muscle Group for Increasing Range of Motion in People Aged 65 Years or Older

et al. 2001

APTA is a sponsor of the Decade, an international, multidisciplinary initiative to improve health-related quality of life for people with musculoskeletal disorders.Background and Purpose. Stretching protocols for elderly people (Ն65 years of age) have not been studied to determine the effectiveness of increasing range of motion (ROM). The purpose of this study was to determine which of 3 durations of stretches would produce and maintain the greatest gains in knee extension ROM with the femur held at 90 degrees of hip flexion in a group of elderly individuals. Subjects. Sixty-two subjects (mean ageϭ84.7 years, SDϭ5.6, rangeϭ 65-97) with tight hamstring muscles (defined as the inability to extend the knee to less than 20°of knee flexion) participated. Subjects were recruited from a retirement housing complex and were independent in activities of daily living. Methods. Subjects were randomly assigned to 1 of 4 groups and completed a physical activity questionnaire. The subjects in group 1 (nϭ13, mean ageϭ85.1 years, SDϭ6.4, rangeϭ 70 -97), a control group, performed no stretching. The randomly selected right or left limb of subjects in group 2 (nϭ17, mean ageϭ85.5 years, SDϭ4.5, rangeϭ80 -93), group 3 (nϭ15, mean ageϭ85.2 years, SDϭ6.5, rangeϭ65-92), and group 4 (nϭ17, mean ageϭ83.2 years, SDϭ4.6, rangeϭ68 -90) was stretched 5 times per week for 6 weeks for 15, 30, and 60 seconds, respectively. Range of motion was measured once a week for 10 weeks to determine the treatment and residual effects. Data were analyzed using a growth curve model. Results. A 60-second stretch produced a greater rate of gains in ROM (60-second stretchϭ2.4°per week, 30-second stretchϭ1.3°per week, 15-second stretchϭ0.6°per week), which persisted longer than the gains in any other group (group 4 still had 5.4°more ROM 4 weeks after treatment than at pretest as compared with 0.7°and 0.8°for groups 2 and 3, respectively). Discussion and Conclusion. Longer hold times during stretching of the hamstring muscles resulted in a greater rate of gains in ROM and a more sustained increase in ROM in elderly subjects. These results may differ from those of studies performed with younger populations because of age-related physiologic changes. [Feland JB, Myrer JW, Schulthies SS, et al.
