Low-volume walking program improves cardiovascular-related health in older adults.

Although numerous sources of evidence show that regular physical activity is beneficial to health, most individuals do not engage in a sufficient amount of physical activity to meet the guidelines set out by expert panels. In addition, the minimum amount of physical activity associated with reduced cardiovascular disease risk markers is not clear in older adults. The purpose of this study was to determine the effects of a 12-week walking program involving an exercise volume below the current minimum physical activity recommendation on cardiovascular disease risk markers in older adults.

The association between physical activity and sex-specific oxidative stress in older adults.

Oxidative stress increases with advancing age and is a mediator of several diseases including cancer, cardiovascular disease, and diabetes. Moreover, postmenopausal women have a lower estrogen concentration, which is associated with elevated oxidative stress. However, there is no definitive evidence regarding the relationship between daily physical activity and oxidative stress status in older adults, including postmenopausal women.

Effects of low-volume walking programme and vitamin E supplementation on oxidative damage and health-related variables in healthy older adults.

Background: Both exercise and vitamin E supplementation have been shown to reduce oxidative stress and cardiovascular disease risk in older adults, and when combined there is evidence suggesting that they act synergistically. The currently recommended amount of exercise for older adults is 150 min/week of moderate-intensity exercise; however, the minimum amount of exercise necessary to achieve health benefits is not known. The purpose of this study was to investigate the effects of 12 weeks of participation in a low-volume walking exercise programme (i.

Antimicrobial effect of alexidine and chlorhexidine against Enterococcus faecalis infection.

A previous study demonstrated that alexidine has greater affinity for the major virulence factors of bacteria than chlorhexidine. The aim of this study was to compare the antimicrobial activity of 1% alexidine with that of 2% chlorhexidine using Enterococcus faecalis-infected dentin blocks. Sixty bovine dentin blocks were prepared and randomly divided into six groups of 10 each.

Low-volume exercise training attenuates oxidative stress and neutrophils activation in older adults.

The purpose of this study was to investigate the effects of low-volume exercise training (100 min/week) on oxidative stress and neutrophils activation markers in older adults. Twenty-eight older adults (age range 65-78 years) were assigned into control (n = 14) or exercise (n = 14) groups. The exercise program consisted of walking 30-60 min/session, 2 days each week for 12 weeks.

Psychological, social, and environmental factors associated with utilization of senior centers among older adults in Korea.

Objectives: The purpose of the study was to examine the relationships among the psychological, social, and environmental factors influencing the utilization of senior centers among older adults in Korea.

Methods: A questionnaire survey was administered to two types of older adults who lived in Seoul, Korea: 262 older adults who used senior centers (3 places) and 156 older adults who did not use senior centers.

Results: Our results showed clearly that the utilization of the senior centers in Korea is affected by higher self-efficacy (odds ratio [OR], 6.

Use of senior center and the health-related quality of life in Korean older adults.

Objective: The purpose of the present study was to examine the relationship between the use of senior center and health-related quality of life in Korean older adults.

Methods: A questionnaire survey was conducted to two types of older adults who lived in Busan, Korea: 154 older adults who used a senior center and 137 older adults who did not use a senior center. The Korean version of short-form 36-item health survey was administered to assess the health-related quality of life.

Oxidised low-density lipoprotein concentrations and physical activity status in older adults: the WASEDA active life study.

Aim: Oxidised low-density lipoprotein (LDL) is considered a risk marker for cardiovascular disease. However, it remains unclear whether oxidised LDL concentrations differ with the physical activity status in older adults. The purpose of this study was to examine the relationship between the amount of physical activity and oxidised LDL in older adults.
