We investigated the relationships between the peripheral circulatory function evaluated by the accelerated plethysmogram (APG) and the cold constitution in female students. The measurements of the APG in fingers were performed in a room at 25.7±0.4°C, using a plethysmography. The APG was evaluated by the waveforms and the scores. Four hundred and fourteen students participated in this study. About a half of the females (n=200; Cold group) recognized the existence of cold constitution. Furthermore, the Cold group was divided into three subgroups (weak; 80.5%, medium; 15%, strong; 4.5%), dependent on the conditions. In general, the females without the cold constitution (Normal group) belonged to the types of good circulation, and higher APG scores. However, there were many females having the types of poor circulation and lower APG scores in Cold group, compared to Normal group. Among the Cold group, the females who have poor waveforms and lower APG scores tended to have severe cold constitution. These findings suggest that the existence and the degree of cold constitution are, at least in part, able to be evaluated by the APG.

The purpose of this study was to investigate the validity of estimated values of maximal oxygen uptake (VO₂max) . The collegiate women who were not currently involved regular physical activity participated in this study. Subjects performed a maximal graded continuous VO₂max test on cycle ergometer (measured VO₂max; M-VO₂max) . The expired gas was measured with gas analyzer. On the other day, the subjects also performed submaximal test on a cycle ergometer. The VO₂max was estimated with ML-1400 system (estimated VO₂max; E-VO₂max) .
The results showed that the mean E-VO₂max was about 10% significant lower than M-VO₂max and the E-VO2max and M-VO2max showed significant positive correlation (r=0.547) . These results suggest that ML-1400 system was suitable for estimat ing VO₂max for a large group of untrained subjects.

Backgrounds: The APG system indicates heart rate variability, by using the coefficient of the variation of the a-a intervals (CVaa%), and also indicates the power rate in the low frequency area and the high frequency area that was derived from frequency analysis (LF/HF) . Purposes: The purposes of this study are to make clear the relationship between CVaa% and LF/HF, to know the standard range of LF/HF in the calm state and in the ordinary state, and to know whether there is a circadian rhythm in the parameter of the frequency analysis. Objectives and method: We recorded APG of one healthy girl of 21 y.o. immediately after waking up in the morning during 62 days. We recorded APG of the 193 healthy (ages 30-59) before exercise and after exercise in the afternoon. Statistical analyses : 1) We indicated the mean of CVaa%, LF, HF, total Power, LF%, HF% and LF/HF immediately after waking up in the morning. We examined the correlation between body temperature and each parameter, and observed the circadian rhythm of each parameter. 2) We analyzed the influence of age and exercise on each parameter. Results: 1) The mean LF/HF in the calm state in the morning was 1.4 (SD=0.9) . The total power, HF and LF had significant negative correlation to body temperature, and showed a circadian rhythm of biphasic. 2) As to 193 men, there was no significant difference among age categories in LF, HF, the total power, HF% and LF% both before and after exercise. There was no significant difference among age categories in LF/HF before exercise, but LF/HF after exercise in the old people was significantly less than in the young people. After exercise, there was not significant change in the total power. While, the HF and HF % significantly decreased and LF % and LF/HF significantly increased after exercise. The 95% confidence interval of the LF/HF before exercise was 2.0-2.6, and that of LF/HF after exercise was 4.3-5.8. The CVaa% had significantly positive correlations to total power, LF and HF, but did not have any correlation to LF%, HF% and LF/HF Conclusion: 1) It can be said that the LF/HF in the calm state is<2.0, the LF/HF in the ordinary state indicates 2-3, and the LF/HF in the condition which it gets excited at is>4.0.2) The CVaa % may reflect the activity of autonomic nerve function, but not reflect the balance of autonomic nerve function. 3) The autonomic nerve function of a young woman has a circadian rhythm of biphasic.

Analysis of complaints, diseases under treatments and life habits of the workers of an IT company were carried out from the interview sheets at their regular medical examinations September 2004. All health data were divided into males and females, and were arranged in the order of their ages. The incidences of each complaint, disease under treatment and life habit were counted separately into four groups; males below 35 years of ages (male young adults), males over 35 years of ages (male elderly adults), females under 35 years of ages (female young adults) and females over 35 years of ages (female elderly adults) . Thirty six% of male young adults, 41% of male aged adults, 11% of female young adults and 22% of female eldeerly adults were found to have no complaints. That is, 36-41% of male were healthy but only 11-22% of female were found to be healthy. Ones who had complaints had plural complaints at the same time; averages 2.8-5.4. Stiff shoulder was the most prevalent complaint; 35% of males and 67% of females were found to have this complaint. Lumbago was the second prevalent complaint; 20% of males and 30-45% of females were found to have this complaint. High incidences of palpitation, short breath and pectoralgia were thought to be due to aging, but higher incidences of these complaints in male young adults than male elderly adults were thought not to be due to physical but to psychological dependences.
Five to six % of young adults and 10-18% of elderly adults were found to have diseases under treatments. Thirty-two % of male young adults, 36% of male elderly adults, 22% of female young adults and 17% of female elderly adults were found to smoke. About 50% of male and female young adults were found to drink, and 77% of male elderly adults and 33% of female elderly adults were found to drink. The female young adults were found to be equally liberated for drinking as male young adults. Only 5% of all four groups were found to do physical exercises regularly. Ninety-five % of young adults and 90% of elderly adults were found not to have enough sleep.
Only 39% of male young adults were found to have breakfast. Over 50% of male elderly adults and females were found to have breakfast. Only 20% of male young adults were found to have three meals a day. Forty-nine% of male elderly adults, 44% of female young adults and 33% of female elderly adults were found to have three meals a day. Workers in this company seemed to eat pool food generally.
