Environmental and Behavioral Conditions of Bathing among Elderly Japanese
This study investigated the bathing conditions of elderly Japanese, and sought to find factors relating to regional differences in death rates from bathtub accidents. A questionnaire survey was carried out in 11 areas of Japan. Questionnaires including questions regarding the length of time since houses had been built, types of facilities, and subjects' indoor thermal sensations and behavior while bathing were distributed to detached houses in ea…
Influence of Long-Term Exposure to an Air-conditioned Environment on the Diurnal Cortisol Rhythm
In the present study, the influence of the long-term use of air-conditioning in summer on the cortisol rhythm was examined by measuring the rhythm in subjects who had been exposed to air-conditioning for a short [S] or long [L] time. Investigations were conducted twice in July and September. Atmospheric temperature and relative humidity near the subjects were measured for three days in each season. Saliva samples for cortisol analysis were collec…
Comparative study on physique and physical fitness of elementary schoolchildren between urban and mountainous rural areas
The physique and physical fitness of the urban and the mountainous rural schoolchildren were compared. The subjects were elementary schoolchildren aged from 9.2 to 12.8 years. The urban samples were 154 boys and 163 girls in an elementary school located at Meguro-ku in central Tokyo. The rural samples were 94 boys and 92 girls from 8 elementary schools in Shiiba village in the Miyazaki Prefecture.The results obtained are as follows:1) There were …
Anthropometry, physical fitness and daily habits with regard to ageing
One thousand eight hundred male workers in an industrial factory were examined in 1981 using anthropometric measurements (height, weight, abdominal girth, chest girth, and skinfold thickness), physical fitness tests (vertical jump, hand grip force, respiratory function, and blood pressure) and a questionnaire about daily habits (cigaret smoking, alcohol consumption, and physical activity), and they were reexamined to compare in 1984.ROHRER'S indi…
Prediction of body composition of young and middle-aged Japanese men
This study was attempted to formulate a new equation for predicting the body composition of young and middle-aged Japanese men from anthropometric measurements. Sixty-four Japanese men aged from 12 to 52 years were measured for body composition using 15 anthropometric dimensions and hydrostatic weighing. Using this sample, the prediction equation of total body volume (TBV) was calculated as follows;TBV=0.9424BW+0.1188AG-0.0695CG-0.0029AGE-2.893 (…
Prediction of Body Composition of Japanese Young Women for Any Levels of Habitual Physical Activity
This study was attempted to make new equation for predicting body composition of Japanese young females at any levels of habitual physical activity. Female athletes (n=51) and non-athletes (n=23) were measured for body composition using 16 anthropometric dimensions and hydrostatic weighing.The analysis of covariance confirmed that the relationship between body density and skinfold measurements was significantly different between the groups. On th…
Physiological Responses During a Light Muscular Exercise in Conditions of Air Temperature between 20°C and 28°C
Eight male students, wearing only shorts, were exposed to 20, 22, 24, 26, and 28°C for 90 minutes on separate days. Relative humidity was 50% and air velocity was less than 20cm/sec. Subjects kept rest in sitting posture for 60 minutes and then took a light fixed work (40W) for 30 minutes on a bicycle ergometer. Their exercise metabolic rate, heart rate, rectal temperature, and mean skin temperature were measured. Measurements between the 25th an…
The Effect of Feet Immersion in Cold Water on the Physiological Responses of Japanese Subjects
Experiments were conducted on four healthy male and four healthy female subjects in an artificial climate room at an air temperature of 241°C and a relative humidity of 60%. Skin temperature of the right index finger, the arm, the forehead and the foot, as well as pain sensation, blood pressure, pulse wave etc. were measured before, during and after simultaneous immersion of both feet for 10min in water at 10°C.Following immersion of the feet, fi…
Heart Rate and Body Temperature Responses during and after Exposure to Cold
In summer, 15 male students wearing only shorts were exposed to 15°C for 90 minutes in supine posture (exposure period), and then they were covered with blankets for 60 minutes (recovery period). Heart rate, blood pressure, heat production, rectal temperature and skin temperatures at 9 sites were recorded on subjects before, during and after exposure to a cold environment.Heart rate decreased significantly under the cold exposure, and in the reco…
Resting Metabolism in Conditions of Air Temperature between 20 and 28°C
Eight male and six female students, wearing only shorts in male or Bikini swimming suits in female, were exposed to 20, 22, 24, 26 and 28°C in a climatic chamber for 60min in sitting posture on separate days. Air velocity was less than 20cm/sec and relative humidity was 50%. Metabolic rate, rectal temperature, mean skin temperature, heart rate and sweat rate were measured. Measurements between the 55th and 60th min of exposure were used for stati…
Wijesekera, N. D., 1964
Six male students performing a standardized exercise were studied in the following conditions: (1) 15°C/50 % R. H. (cool condition), (2) 20°C/50 % R. H. (comfortable condition), (3) 35°C/30 % R. H. (warm-dry condition), and (4) 35°C/80%R. H. (warm-humid condition). The exercise consisted of pedaling a bicycle ergometer for 20 minutes at moderate work load followed by a 4-minutes period of heavy work. Pulmonary ventilation, oxygen uptake, carbon d…
The Change in Physical Working Capacity Shown as PWC 120 , PWC 150 and PWC 170 during Prolonged Muscular Exercise
The purpose of this investigation is to study the relations between the physical working capacity and rectal temperature during muscular exercise.Subjects were six healthy male young adults (Table 1). 60 minutes bicycle exercises were carried out at work rates requiring 30, 40, 50 and 60% of the subjects' maximal oxygen uptake. Heart rate and rectal temperature were measured every ten minutes during the works. Rectal temperatures ranged between 3…
