This study deals with comparative physiological changes such as basal metabolism (BM) between two inhabitants of Hirosaki, a cold district in Japan. One of the matched male subjects was a permanent inhabitant while the other had immigrated from Tokushima, a warm district in Japan, half a month before. From May 1969 to September 1970, body weight and physiological functions such as BM and others were measured every morning. Subjective estimations of their amount of work, dietary intake, the way they felt about the temperature on the previous day (temperature feeling), how fatigued they had felt when they got up (fatigue feeling), and how well they had slept (sleeping condition) were recorded by means of a five-grade scaling method. It was supposed that these factors would affect BM. The results were as follows: 1. Differences in the values of the above influencing factors on BM between the immigrant and the permanent inhabitant were large during the early period of experiment, but they diminished and almost the same values were obtained from October 1969, except in November. Differences in decending order between the subjects were found in temperature feeling, fatigue feeling and sleeping condition, while amount of work and dietary intake were not so different. 2. The changes of BM showed a pattern that had a peak during the hottest period in summer for both the immigrant and the permanent inhabitant from May to October 1969. It was possible that the difference in climate and geografical features affected the immigrant like a stress, and the high temperature and sports in summer affected the permanent inhabitant. However, after October 1969 there were differences in BM between the two subjects. The immigrant had a high BM during the warm period of spring, but the value was sharply lowered during the hottest period of summer. This change was quite different from that of the permanent inhabitant which followed the normal pattern. 3. R.Q. of the two subjects peaked highly in winter and lowly in summer. The values were a little higher for the permanent inhabitant than for the immigrant. Although the body weight of the immigrant increased a little in winter and decreased a little in summer, such a seasonal change was not observed for the permanent inhabitant. 4. The significant relationship between the average monthly atmospheric temperature and the monthly variation of BM from October 1969 to September 1970 was obtained for the permanent inhabitant. The critical atmospheric temperature, that raised and lowered his BM, was 9.8°C. The immigrant was found to have such a relationship only during the limited period between April and July. 5. The representative mean values of monthly BM, which were measured on one day in the middle of month, on three days during the same period, on sixdays, i.e. two days of each of the three ten-day periods, and on every day, were compared with one another. The values of the one- and three-day measurements were considerably different from those of the every day measurements in the months during which there were large climatic changes, such as April, June or September. These monthly changes were shown to be markedly different. However, the values of the six-day measurements were similar to those of the every day measurements. It is supposed that at least six days are necessary for the measure-ment of BM during sudden changes of climate. But, it would be more desirable to increase the number of measurements to obtain more accurate data.
The purpose of this report is to measure physical load of students on practice of sports in a senior high school. Donaggio's reaction on urines before and after practice of base-ball and kendo by students demonstrates the following results. 1) A coefficient of correlation between the titer of Donaggio's reaction of deprote-inization treatment by heating urines and that of omitting the treatment by heating urines before practice of base-ball shows 0.84 and that after practice of base-ball shows 0.83, which are very correlative. 2) The titer of Donaggio's reaction corrected with specific gravity of 1.024 is better than actual titer of Donaggio's reaction. 3) The results on the high titer of Donaggio's reaction corrected with specific gravity of the urines of students before practice of sports indicate accumlation of fatigue, which needs to be taken steps for them to encounter more exhaustion and to get over tiredness. 4) Counterimmunoelectrophoresis shows the presence of HH, Znα2 and myoglobin in the urines before practice of sports and the increase of Znα2 and myoglobin after practice of sports. The presence of myoglobin in the urines before practice of fatigue of foregoing day. 5) There is little correlation between titer of Donaggio's reaction and complaints of fatigue caused by physical load on practice of sports.
It is studied in this paper whether the current physical growth rate over four seasons parallels the physical growth rate over four seasons as observed in previous studies. For these purposes, some physical growth traits influenced by urbanization among rural school children were investigated in comparison with urban school children using the longitudinal method. The results obtained were as follows: 1) Fathers whose only job was farming in the rural sample, were decreasing; conversely farmers having other jobs were increasing. Number of siblings were two in average and families with both parents working increased in rural sample, thus the rural school children were observed being influenced by urbanization remarkably. 2) As for the physical growth rate, the tendency to show remarkable growth in spring was observed to be decreasing, because the season of maximum growth was dispersed among the four seasons, the season depending on age. This is, significantly different physical growth rates were observed in all seasons in addition to spring; therefore growth rate seems to be averaging over seasons as a whole. 3) The change of periodicity in one year was observed in both samples in the process of physical growth on height. 4) But on the other hand, study of the percentage of school children showing maximum growth by seasons revealed that the percentage of those with maximum growth in summer and spring was highest, and those with maximum growth in autumn and winter was lowest. This same seasonal growth was observed in both samples. 5) The two results mentioned at 2) and 4) obtained between the physical growth rate and the percentages of school children showed a possible point of disagreement regarding the maximum growth rate. It should be understood that most of the school children showed maximum growth rate in summer and spring, but the difference of growth rate between these two seasons and the other ones was decreasing.
