BACKGROUND While community-wide interventions to promote physical activity have been encouraged in older adults, evidence of their effectiveness remains limited. We conducted a qualitative study among older adults participating in regular group exercise to understand their perceptions of the physical, mental, and social changes they underwent as a result of the physical activity. METHODS We c...

The aim of this study was to investigate the degree to which genetic and environmental influences affect variation in adolescent exercise behavior. Data on regular leisure time exercise activities were analyzed in 8,355 adolescent twins, from three-age cohorts (13-14, 15-16, and 17-19 years). Exercise behavior was assessed with survey items about type of regular leisure time exercise, frequency...

conclusions we suggest that regular aerobic exercise can favorably alter the inflammatory profile, which is a known risk factor in breast cancer development, in postmenopausal women. patients and methods this study was a randomized controlled trial. we randomly assigned 41 postmenopausal, sedentary women aged 50 to 74 to either an exercise or a control group. the intervention involved facility-...

background: guidelines recommend that exercise training can be considered for medically stable outpatients with heart failure; thus, this study sought to determine the effect of exercise on quality of life in patients with heart failure. patients and methods : in this cross sectional study 160 patients were included and divided into 2 groups (n=80). intervention group performed the exercise (po...

Persistent low-grade systemic inflammation is a feature of chronic diseases such as cardiovascular disease (CVD), type 2 diabetes and dementia and evidence exists that inflammation is a causal factor in the development of insulin resistance and atherosclerosis. Regular exercise offers protection against all of these diseases and recent evidence suggests that the protective effect of exercise ma...

Studies on the determinants of physical activity have traditionally focused on social factors and environmental barriers, but recent research has shown the additional importance of biological factors, including genetic variation. Here we review the major tenets of this research to arrive at three major conclusions: First, individual differences in physical activity traits are significantly infl...

BACKGROUND AND PURPOSE Regular exercise can result in changes in the levels of oxidative stress in the hippocampus; however, little attention has been paid to physical-activity-induced neuronal protection to exposure to lead compounds. This study investigated the effects of regular treadmill exercise on a DNA oxidative-damage marker [8-hydroxy-2'-deoxyguanosine (8-OHdG)] and the total antioxida...

The benefi ts of regular exercise to one’s physical health are widely known. Besides its benefi ts to physical health, exercise is also effective for improvements to both mental health and quality of life [Takenaka, (1998, 1999)]. However, although those benefi ts are recognized, it is not easy to continue regular exercise practices. In Japan, it is less than 30% of the total population those w...
