The interactions of sex, age, season, and habitual physical activity were examined in 41 male and 54 female Japanese age 65-83 yr, using a pedometer/accelerometer that determined step counts and amounts of physical activity (<3 and >3 metabolic equivalents [METs]) throughout each 24-hr period for an entire year. All 3 measures were greater in men than in women. In women, age was negatively correla...<br/><br/>Akitomo Yasunaga, Fumiharu Togo, Eiji Watanabe, Hyuntae Park, Sungjin Park, Roy J Shephard, Yukitoshi Aoyagi (2008) <i>J Aging Phys Act</i> <i></i> <i></i> 16: 1 3-13<br/>

Although various environmental factors, such as a high-salt diet, a smoking habit, excessive alcohol intake, and physical inactivity, influence the development of hypertension, genetic variation also contributes to an individual's susceptibility to this condition. The purpose of the present study was to identify gene polymorphisms that confer susceptibility or resistance to hypertension, and there...<br/><br/>Yoshiji Yamada, Kimihiko Kato, Tetsuro Yoshida, Kiyoshi Yokoi, Hitoshi Matsuo, Sachiro Watanabe, Sahoko Ichihara, Norifumi Metoki, Hidemi Yoshida, Kei Satoh, Yukitoshi Aoyagi, Akitomo Yasunaga, Hyuntae Park, Masashi Tanaka, Yoshinori Nozawa (2008) <i>Int J Mol Med</i> <i></i> <i></i> 21: 1 83-89<br/>

In Japan, the "bedridden state" is one of the most serious problems the aged face, and it is becoming a social problem. The main causes of the bedridden state are cerebrovascular disorders and bone fractures following falls. The purpose of this study was to predict risk factors for falls and resultant bone fracture due to osteoporosis. We explored mobility parameters for possible fall prevention. ...<br/><br/>Taiki Komatsu, Kang Jung Kim, Tetsuo Kaminai, Hiroyasu Okuizumi, Hiroharu Kamioka, Shinpei Okada, Hyuntae Park, Ayumi Hasegawa, Yoshiteru Mutoh, Iwao Yamamoto (2006) <i>J Bone Miner Metab</i> 24: 5 419-424<br/>

We hypothesized that the health-related quality of life (HRQOL) would be poorer in physically inactive older adults. This was tested in a sample of 73 male and 108 female free-living healthy Japanese participants, age 65-85 years. We measured accelerometer step counts and their metabolic equivalents (METs) throughout each 24-hr period for 1 year. At the end of the year, HRQOL was assessed.

Seasonal changes in ambient temperature and day length are thought to modify habitual physical activity. However, relationships between such environmental factors and the daily physical activity of older populations remain unclear. The present study thus examined associations between meteorological variables and the number of steps taken per day by elderly Japanese.
