—A study of the difference by housing type and age—Yoshiaki Yamato, Naoki Matsubara, Yoshihito Kurazumi2005 Volume 42 Issue 4 Pages 111-122

JOURNAL FREE ACCESSThe purpose of this study is to clarify the difference in resident's postures in their living rooms, by housing type and age. The survey was conducted on different types of dwellings in and around Kyoto city during summer. In the male group, lying increased among those up to 60s as they became older, while floor-sitting and chair-sitting decreased. Chair-sitting was minimum in condominiums of RC building and non-insulated detached house, and floor-sitting was hardly seen in Solar house. In the female group, floor-sitting was highest in all age groups. Among those of over 30 years old, floor-sitting decreased, while lying and chair-sitting increased. More chair-sitting and floor-sitting were observed in insulated detached house and condominiums of RC building respectively. Lying and floor-sitting accounted for large portion in non-insulated detached house and solar house. Age-related difference in the postures was observed. Both men and women determined their postures to become cooler, as they got older. The aspect of the behavioral temperature regulation in choice of a posture was observed. The difference in the postures by the thermal performance of dwelling types was not found, and that by housing type is considered the effects by flooring materials.

JOURNAL FREE ACCESSThe purpose of this study is to clarify the difference in resident's postures in their living rooms, by housing type and age. The survey was conducted on different types of dwellings in and around Kyoto city during winter. In the male group, lying increased among those up to 60s as they became older, while floor-sitting was highest in the group under 10 years old. In condominiums of RC building, lying and floor-sitting dominated except for residents of 70 years and up, and chair-sitting accounted for large portion in Insulated detached. In the female group, floor-sitting ranked highest in all age groups. Among those under 30 years old, lying also ranked high. As they became older, lying decreased, while chair-sitting increased. In condominiums of RC building, lying and floor-sitting dominated except for residents of 70 years and up. In insulated detached, more chair-sitting cases were observed, and in non-insulated detached, lying ranked higher than the entire average. Many residents were using the kotatsu, electric carpets and floor heating system to warm their living rooms. Based on the fact that people took lying and floor-sitting postures to get more heat from those heating systems, the aspect of behavioral temperature regulation was observed in choice of a posture.

—In particular by an aspect of hydration—Osamu Kashimura, Seiichi Nakai2005 Volume 42 Issue 4 Pages 137-144

JOURNAL FREE ACCESSThe purpose of this study review the actual situation from an aspect of water intake about body weight loss, body temperature and pulse rate at summer running in the middle-aged runners. The subjects carried out running regularly with well male eight people of 55 years old from age 40 years old. The experiments measured loss of weight (almost equivalent to sweat rate), elevation of body temperature, pulse rate and environmental temperature during the running early in morning for about 60 minutes. This experiment was carried out in summer, 1998. The experiments carried out the case that did not do drinking when we ground drinking at running. Mean WBGT during running were 29.4±0.5°C. The rates of weight loss at running increased by the supplying of water, and the rise of tympanic temperature decreased by the supplying of water. It was appeared that the negative correlations were presented between quantity of water to drink and rises of tympanic temperature. As for the same condition of WBGT, body weight loss was significantly water drinking greater than water nothing drinking. Also, for the same condition of tympanic temperature, body weight loss was significantly greater water drinking than that nothing drinking. For the same average pulse rate it was found that rate of body weight loss was significantly water drinking greater than that nothing drinking. From the above, it was shown that summer running in the middle-aged runners was easy to occur heat-stroke disorder for the heat environmental condition and severe exercise load, and the supplying of water was important to prevent that disorder.

Yasushi Takumi, Kiyoshi Moriya2005 Volume 42 Issue 4 Pages 145-157

JOURNAL FREE ACCESSThis study investigated the heart rate (HR) and the compound acceleration during exercise as a measure of exercise intensity, and the change of exercise quantity and physical fitness level in participants in YOSAKOI SORAN dance festival. The subjects were dancers belonging to a team in Hokkaido in which many middle-aged and elderly peoples participated and which usually held dance practices twice a week for four months from February. The maximal HR of a middle-aged dancer during dancing was over 180 beats/minutes, so that the exercise intensity of the dance was considered very high. Significant positive correlation was observed between HR and compound acceleration during dancing. The maximal HR during dancing in the festival was sometimes about 20 beats/minutes higher than in dance practice. This was considered to be because of tension at the festival or weather. In subject NR (50 yrs, female), the numbers of steps and exercise quantity per day were significantly more on dance-practice days than on non-practice days. The physical fitness level of participants in YOSAKOI SORAN was improved over the four months. Participation in the dance practice and the festival of YOSAKOI SORAN was suggested as being effective for health promotion for people who live in cold areas where exercise quantity in winter becomes insufficient.
