Whether there is a regular fluctuation of female basal metabolism related to menstrual cycle has not been decided yet, in spite of many authors' efforts. Some of them recognized the fluctuations of the basal metabolism, but did not found a common rule among them. However, concerning the body temperature, a physiological rise right after ovulation continued until next menses has been confermed in most of healthy women. So, this experiment was conducted, expecting that it may be a easier way to survey the basal metabolism correlated with body temperature, in order to find out the common rule of its fluctuation. Daily basal metabolism of two girls aged 21 and 23 years measured by Douglas bag method for 38 days. Body temperature under tongue was surveyed with a mercury thermometer equipped in special accuracy. Results were as follows: (1) The correlation coefficients between basal metabolism and body temperature wer amounted to 0.5-0.7. The basal metabolism is usually influenced by many kinds of factors, therefor these correlation would mean “basal metabolism is in a parallel relation with body temperature”. (2) The maximum deviations from arithmetic mean of the basal metabolism during 38 days were ±7% and ±6% in two girls. The same kind of deviations of 3 girls conducted by a respiration chamber method in 1936 at this institute were ±%, ±9%, and ±7%. These results show that Douglas bag method can not be inferior in accuracy than chamber method.
The project of this investigation is to investigate the calorie requirement of the physically handicapped persons, suffering from extremities amputations, infantile paralysis and articular rigidities. Their basal metabolism and working metabolism as well as food intake were investigated. The average of their basal metabolism was 1.30 Calorie per kg. per hour which was much higher than the Japanese standard by 21%. The case of the spinal infantile paralysis showed the highest, and the cerebral infantile paralysis was the lowest among them. Those who has an artificial leg or had suffered from infantile paralysis consumed 1.5-3 times of energy more in walking or ascending stairs compared with the normal, but not much in bycicle-ergometer. The cause of the higher basal metabolism, which seemed to come from the active protoplasmic mass, will be studied later.
The food intake and time distribution of daily works of 51 policemen were surveyed on june 1951, in Tokyo to. They fell into several groups which differed with respect to their works or residences. Their average daily food intake during 3 days, together with the time for their daily works, were investigated. According to the results, it is considered that their average daily intake of nutrients is adequate except with respect to vitamins and calcium, as compared with the recommended dietary allowance. The nutrient intake of policemen on 1st duty is generally better than those of the policemen on other duties. It is further considered that the policemen in dormitories tend to eat diets worse than at homes. From the results of the study of their time for works in a day, it is estimated that the average amount of energy expenditure is about 2400-2500 calories on duty days, and adout 1800-2000 calories on off-duty days, and they have only a short time for their own culture and amusement.
Studies of time for domestic life in 32 housewives in Kanagawa prefecture were done on February, 1951 They fell into 4 groups according to whether they have babies and infant or not. Time spent in house hold works is about 8 hours on weekdays and 65 hours on Sunday, It is longer in A group (large families with babies and infants) than in B group (large farmilies without babies and infants) and C group (small families without babies and infants). There average energy expenditure estimated from the above data is about 1700-2000 calories a day and is highest in A group among them. There is no difference between weekday and Sunday in each group.
