“…For example, Iemitsu et al (15) reported lower systemic arterial stiffness in a physically active group than in a physically inactive group. Gando et al (19) and Nishiwaki et al (32) showed that physical activity reduces arterial stiffness in older adults. The present results show that baPWV and CAVI were significantly increased from baseline after the 75-g OGTT in the inactive but not the active group in older people with impaired glucose tolerance.…”

We compared arterial stiffness after glucose intake in active and inactive elderly people with impaired glucose tolerance and clarified whether physical activity was associated with arterial stiffness after ingestion of glucose. Twenty older adults with impaired glucose tolerance were analyzed in a cross sectional design. Based on the international physical activity questionnaire, participants were divided into the active group (daily step count: 10,175.9 ± 837.8 steps/day, n = 10) or the inactive group (daily step count: 4,125.6 ± 485.9 steps/day, n = 10). Brachial-ankle (systemic) and heart-brachial (aortic) pulse wave velocity and cardio ankle vascular index (systemic) were increased at 30, 60, and 90 min compared to baseline after a 75 g oral glucose tolerance test in the inactive but not the active group. Heart-brachial pulse wave velocity did not change compared to baseline after a 75 g oral glucose tolerance test in either group. The area under the curve for brachial-ankle pulse wave velocity was associated with daily living activity (r =-0.577, p = 0.008), daily step activity (r =-0.546, p = 0.013), and the daily step count (r =-0.797, p = 0.0001). The present findings indicate that physical activity or inactivity is associated with arterial stiffness following glucose ingestion.

“…Brachial-ankle PWV (baPWV), heart-brachial PWV (hbPWV), blood pressure (BP), and heart rate (HR) were measured using a PWV/ABI vascular testing device (Omron-Colin Co., Ltd., Kyoto, Japan) 19,20) . CAVI was measured using a VaSera VS-1500AE vascular testing device (Fukuda-Denshi Co., Ltd., Tokyo, Japan) 21) , and AVI and API were measured using a PASESA AVE-1500 vascular testing device (Shisei Datum Co., Ltd., Tokyo, Japan) [15][16][17][18]22) . VO 2peak was assessed via an incremental test to exhaustion (1 min warm-up at 15 Watt, cycling at 15 Watt, followed by a 15 Watt/min increase).…”

In the present study, we investigated the effects of regular aerobic training with different intensities and durations on new indices of arterial stiffness measured via an upper-arm oscillometric device. [Participants and Methods] We gathered data from 41 middle-aged and older people (age 65.0 ± 11.7 years). Participants were randomly divided into five groups: (1) 15 minutes of low intensity aerobic training (n=10); (2) 30 minutes of low intensity training (n=7); (3) 15 minutes of moderate-intensity training (n=9); (4) 30 minutes of moderate-intensity training (n=8); and (5) a non-training group (n=7). Training was conducted for 8 weeks, three times per week. Arterial pulse wave index, arterial pressure-volume index, brachial-ankle and heart-brachial pulse wave velocity, cardio-ankle vascular index, brachial and ankle blood pressure, heart rate, and peak oxygen uptake were measured before and after the intervention. [Results] All indicators of arterial stiffness and brachial and ankle blood pressure in the exercise groups were significantly lower after versus before the intervention. Peak oxygen uptake did not differ before versus after the intervention. [Conclusion] The present findings indicate that regular aerobic exercise may be important in reducing arterial stiffness regardless of the intensity or duration of aerobic exercise.

“…The 6-meter (m) walk test proceeded as follows. The participants started to walk three meters before a start line to exclude the duration of acceleration from normal walking speed, then walked as fast as possible without running for 6 m. Speed was calculated as the ratio between distance and time 13) . All daily coefficients of variation (CV) were <10%.…”

The numbers of "old-old" and "young-old" adults (age ≥75 y [years] and 65-74 y, respectively) are now about the same, but less is known about the physiological characteristics such as arterial stiffness in old-old adults, especially those aged >85 y. Therefore, the present cross-sectional observational study aimed to determine the characteristics of blood pressure (BP), arterial stiffness, and physical fitness among 559 (male, n = 213; female, n = 346) Japanese community dwellers aged >65 y in Osaka and Kawakami Village, Nara. BP and arterial stiffness were measured in the supine position using a semi-automated device. Physical fitness was assessed by measuring handgrip strength and walking speed, as well as findings of the sit-and-reach and pegboard tests. Values for systolic BP, mean BP, and arterial stiffness were significantly higher in the old-old than young-old community dwellers. Trends in BP and arterial stiffness significantly increased, whereas those of physical fitness significantly decreased with age per decade. This is the first study to show that the physiological characteristics of BP, arterial stiffness, and physical fitness in Japanese community-dwelling older adults over 80 y. These novel findings indicate that community-dwelling older adults, especially nonagenarians, can maintain the longevity characteristics of lower arterial stiffness and higher physical fitness such as handgrip strength.
