The acute effect of passively assisted trunk stretching on central arterial stiffness and blood pressure in middle-aged to older adults.

PURPOSE: We examined the effects of acute trunk stretching on central arterial stiffness and central and peripheral blood pressure in middle-aged to older adults. METHODS: Twenty-eight middle-aged to older adults (14M/14F, 72 ± 7 years, 28.5 ± 5.3 kg/m2) completed this randomized, controlled, crossover design trial. We measured carotid-femoral pulse wave velocity (cf-PWV) and central and peripheral blood pressures (BP) before and after a single bout of passively assisted trunk stretching (i.e., five rounds of six 30-s stretches) and a time-matched seated control visit (i.e., 30-min). Changes (Δ; post - pre) in cf-PWV and central and peripheral BP were compared between visits and sexes using separate linear mixed-effects models controlling for baseline values. RESULTS: Compared with seated control, central (systolic: - 3 ± 7 mmHg; diastolic: - 2 ± 5 mmHg) and peripheral (systolic: - 2 ± 8 mmHg; diastolic: - 1 ± 4 mmHg) BP were reduced following acute trunk stretching (ps ≤ 0.001). Between-visit differences for ∆cf-PWV (stretch: 0.09 ± 0.61 m/s; control: 0.37 ± 0.68 m/s, p = 0.038) were abolished when controlling for change in mean arterial pressure (∆MAP) (p = 0.687). The main effects of sex were detected for changes in systolic BPs (ps ≤ 0.029); more males (n = 13) saw BP reductions than females (n = 7). CONCLUSION: These findings demonstrate the superiority of acute trunk stretching over passive sitting of equated duration for BP in middle-aged to older adults, with an appreciable effect in males compared to females.

Hope, optimism, and self-care among Better Breathers Support Group members with chronic obstructive pulmonary disease.

The objective of this study was to determine the levels of hope, optimism, and self-care of persons with chronic obstructive pulmonary disease (COPD) who attend community-based Better Breathers Support Group (BBSG) meetings. A convenience sample of 68 BBSG members from 14 groups in three southeastern states participated. The data were collected with a questionnaire set composed of a demographic form and three previously tested research instruments: the Herth Hope Index (HHI), the Alberto Chronic Obstructive Pulmonary Disease Self-care Behavior Inventory (COPDSC), and the Life Orientation Test--Revised (LOT-R). The findings (n = 68) include a significant and positive relationship between the HHI and COPDSC (r = .39; p > .01), between the LOT-R and COPDSC (r = .41; p > .001), and between the LOT-R and HHI (r = .59; p > .001). So, those participants with higher Hope and Optimism have higher levels of Self-care. We concluded the participants were fairly optimistic (LOT-R average = 23.75+/-4.49) and hopeful (HHI average 39.47+/-5.61). The average score on the COPDSC was 141.57 (+/-14.76) indicating a high level of self-care.
