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…
Preferable body build indices in children
Body build indices derived from height (H) and weight (W) as the form of W/Hp were assessed for suitability or validity in children. Approximately 8, 000 schoolboys and girls aged 6 to 17 years living in northern Kyushu were analyzed. The ideal power of p was determined according to a general consensus that the best body build index shows the lowest correlation with height and the highest correlation with fatness. Based on allometry, it was found…
Age and sex differences of blood pressure in old age
Blood pressure levels in old age, ranged from 63 to 90 years, are reported with special reference to age and sex differences. Data were cross-sectionally collected from the medical examination for the aged at a certain hospital in Tokyo, consisting of 360 men and 500 women who had been under no medical treatment for hypertensive diseases. Blood pressure was recorded with right upper arm at heart level in the sitting position after the subject res…
Criteria of leanness in schoolboys and girls on the basis of allometry
This study was made to establish criteria of leanness in schoolboys and girls by means of allometry ; leanness was defined as lower lean body mass to height. Anthropometric measurements were taken on approximately 8, 700 children ages 6 to 17 years from elementary school, junior and senior high school in northern Kyushu. Percent body fat and lean body mass were estimated from height, body weight and skinfold thicknesses. Allometric equations of l…
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 …
The Effect of Aging on Stature and Body Weight for the Aged
The present paper describes the changes in physical characteristics of the aged, especially in stature and body weight with increasing age. Samples consisted of 1002 old men and women aged from 63 to 90 years old, and 13.4% of these subjects could be followed up at the interval of more than five years. These cross sectional and longitudinal data were compared with each other. Results obtained cross sectionally revealed that stature for males decr…
The Lower and Upper Critical Temperatures for Oxygen Intake at Rest
A new system named the polynomial equation method was proposed in the present study for the determinations of the lower and upper critical air and body temperatures for oxygen intake at rest. Nine young adult males were tested by the new method and the critical temperatures of them were determined as follows: the lower critical air temperature to be 23.8°C, the upper critical air temperature to be 45.4°C, the lower and upper critical mean skin te…

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…
Prediction Equations of Body Density in Japanese Young Men
This study was attempted to make new equations for predicting body density of Japanese young men from skinfold and/or girth measurements. The subjects were 31 healthy young men aged from 19 to 25 years old. Body density and some anthropometric parameters, such as body weight, height, skinfold thickness and girth, were determined. The body density was estimated by underwater weighing method. Subjects were immersed underwater in the squat position …
Sex Difference in Oxygen Intake and Heart Rate during Assuming Ten Basic Postures under Different Air Temperature Conditions
Twenty four young female and male subjects, twelve in each, all in good physical conditions, volunteered for this study. Examinations were made during the following ten basic postures: lying awake, sitting with crossed legs on the floor, sitting on a chair, squatting with hands on knees, bending with trunk forward from standing posture, standing at ease, standing with attention, half rising posture with knees nearly extended, half rising posture …
The Relations between Body Composition and Aerobic Work Capacity in Fukuoka Residents Aged 12, 13 and 18, 19 Years
The estimated maximal oxygen uptake and some indices of body size and composition, including body height, weight, and skinfold thickness at two sites have been determined on subjects aged 12, 13 and 18, 19 in Fukuoka during step work. Sex difference in maximal oxygen uptake in aged 18, 19 groups and age difference in body fat percent of weight in females were shown significantly. There were different regression equations of maximal oxygen uptake …
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…
Factor of Physical Fitness Test and Relationships with Physical Characteristics in Young Adult Females and Males
This study was made to investigate the factor of physical fitness test, which has been developed by the Ministry of Education and consists of seven different measurements such as side step, sargent jump, back strength, grips strength, trunk extension, trunk flexion and step test, and the validity of estimation for the total score of the tests from several physical characteristics. Physical fitness test, morphological and physiological characteris…
The Effects of Prolonged Muscular Work on Oxygen Intake, Heart Rate and the Relation between Both of Them
Under a normal temperature environment we studied the effects of prolonged muscular work on heart rate and oxygen intake and the relation between both of them.The subjects were six healthy young male students (Table 1). They carried out one-hour work with a bicycle ergometer of 30, 40, 50 and 60% of their maximal oxygen intakes. This led to mean rectal temperature increases respectively 0.4, 0.6, 0.9 and 1.4°C. Submaximal work at first 30% and th…
Indirect Determination of Maximal Oxygen Intake at Different Air Temperature Conditions
The purpose of this study is to make a nomogram for estimating maximal oxygen intake at 20°C, 30°C and 40°C of air temperature and to investigate the reliability and validity of it.Two male subject groups volunteered for this study. Group I consists of students of Kyushu Institute for Design Research, none of them has a career as an athlete or special experiences of physical training. Group II is students of Department of Physical Education in Hi…
