The aim of this report is to investigate the effects of 8 weeks of intensive Tai Chi Chuan (TCC) training on physiological function and fear of falling (FOF) in the less-robust elderly. Forty-nine community-dwelling elderly, aged 60 or older, were classified randomly into a TCC training or control group. Physical performance measures (including one-leg(More)
PURPOSE To investigate the association between green tea consumption and mortality from all causes, cancer, and cardiovascular disease (CVD) among elderly people. METHODS In a population-based, prospective cohort study, a total of 14,001 elderly residents (aged 65-84 years), randomly chosen from all 74 municipalities in Shizuoka, Japan, completed(More)
This cross-sectional study examined the benefits of social dancing on postural stability and physical performance in dancers aged 50 years or more. Walking speed, lower limb reaction time and low back flexibility were measured in 202 social dancers and 202 community-dwelling comparison subjects aged 50-87 years. The results showed that dancers who were(More)
OBJECTIVES The number of studies investigating the health effects of long-term exposure to air pollution is increasing, however, most studies have been conducted in Western countries. The health status of Asian populations may be different to that of Western populations and may, therefore, respond differently to air pollution exposure. Therefore, we(More)
BACKGROUND Physical activity recommendations for older adults with poor health needs to be understood. PURPOSE This study aims to examine the association between the frequency of physical activity and mortality among a sample of elderly subjects, most of whom were under treatment for pre-existing disease. METHODS Data on the frequency of leisure-time(More)
Few epidemiological studies have examined the potential protective effects of physical activity on insomnia. The authors thus evaluated the association between physical activity and insomnia in a large population-based study in Shizuoka, Japan. Individual data were obtained from participants in an ongoing cohort study. A total of 14,001 older residents who(More)
BACKGROUND Regular aerobic exercise is widely recommended for essential hypertensives. However, it is not clear how much exercise is needed to reduce blood pressure (BP). METHODS The dose-response relation of exercise training and BP was determined using an 8-week exercise intervention study involving 207 untreated subjects with stage 1 or 2 essential(More)
OBJECTIVE To investigate the associations between sleep duration and mortality in the elderly by controlling for sleep quality. METHOD Data were collected from participants in a cohort study in Shizuoka, Japan. A total of 14,001 elderly residents (aged 65-85 years), randomly chosen from all 74 municipalities in the prefecture, completed questionnaires(More)
The relationships among walk steps, exercise habits and peak oxygen consumption (VO2peak), ventilatory threshold (VT) and leg extension power (LEP) were examined in 709 apparently healthy Japanese subjects (male 372, female 337) aged 30-69 years. Walk steps were evaluated using a pedometer. VO2peak and VT were assessed by a cycle ergometer test, while LEP(More)
A number of studies have linked exposure to long-term outdoor air pollution with cardiopulmonary disease; however, the evidence for stroke is limited. Furthermore, evidence with the risk for lung cancer (LC) is still inconsistent. We, therefore, evaluated the association between long-term exposure to traffic-related air pollution and cause-specific(More)
