Part I. The imfluences of postural changes and exercise loading upon pulse rates and blood pressure level. Part II. Criticism upon some tests of physical strength. With special .reference to healthy men of the Japanese Self-Defense Force (J. S. D. F.), the examination of bodily strength was performed by means of Harvard's step test, Schneider's test and J. S. D. F.'s test (arm stretch and flection in arm-toe position) at Tab. 1 Mean and Standard Deviation for each Measurement [table] Healthy Self Defence Men 600 cases Age 18〜31 yrs (Average 23.7 yrs) as well as in standing and to the fluctuation of the systolic pressure level due to postural change. Therefore the cardio-pulmonary index may be said not to have any uniform degree of the correlation to every item of the scorings, that is, one might say that the overestimation of three items above mentioned is not quite fair. Tab. 3 Correlation between Each Constituent of Schneider's Index and Others (400 cases) [table] Level of Significance σr=1/√<N-1>, 30σr<r, 3σr=±0.150 Furthermore these three items were not co-related to the scores obtained by 100 m's, 1500 m.'s and 10000 m.'s running tests respectively, so that the synthetic estimation with three sorts of scores may not, just as it is, be regarded as the criterion of the physical strength. Then, in order to examine whether any error may exist in the scoring of each item, the correlation was investigated among the scoring of each item. As shown in tab. 3 and fig. 4, the significant correlation could not be observed among the increase in the pulse rates by recumbence and standing; so far as the range of the pulse rates in recumbence adopted for samples is concerned (nig. 4), these may be no necessity to score the increasing rate of the pulse rates by standing with regard to the extent of the pulse rates in recumbence as Schneider had already emphasized. So that even if the increase in pulse rates by standing would be significant for the criterion of the cardio-pulmonary function, yet there [figure] Fig. 2 Frequency Distribution of Harvard-Step-Test Score (96 Cases) [figure] Fig. 3 Frequency Distribution of Schneider's Index (400 Cases) [figure] not, and its result was summarized in Tab. 2. The significant correlation could not be found between the time requied to 100 m.'s running and the latter three. However, the time requied to 1500 m.'s and 10000 m.'s running had a certain relation to the pulse rates after J.S.D.F.'s test and the scores by Harvard's step test. The pulse rates after J.S.D.F.'s method was more intimately related to the scores at 1500 m.'s running than those by Haverd's step test, but less intimately to the scores at 10000 m.'s running than the latter. From the results above mentioned, even though the merits and demerits of three kinds of tests can not easily be discussed, so far as the examination of bodily strength is concerned, however Harvard's step test and J.S.D.F.'s method may be concluded to be more available than Schneider's test. The similarity of the results seen between Harvard's step test and J.S.D.F.'s method can be attributable to the common feature of these tests which do not take up both the severity of the load and the pulse rates before the load, but adopt the pulse rates for their criterions. These two methods are fairly siutable to screen the bodily strength in mass population owing to the methodological simplicity and the relatively high reliance. Nextly, in order to study why Schneider's cardie-pulmonary index does not show any correlation to the scores obtained by the running test, the propriety of both estimation of every item of scoring and its synthetic descrimination was investigated. The cardio-pulmonary index showed the close correlation to the pulse rates in recumbence Tab. 2 Correlation between Running and Simple Circulatory Function Test [table] which pulse rates come importantly into play (Tab. 1). The time required at 100 m.'s 1500 m.'s and 10000 m.'s running test was used to the quantitative criterion of physical strength. J. S. D. F.'s test is a series of twenty bodily exercises composed of two kinds of actions, i.e. one action at 1", then stretchflection of arms in arm-toe position at A". The pulse rates are measured for one minute at 15" after the load test. Fig. 1 shows the frequency distribution of the pulse rates after the load test. The slope of the right limb of the curve is found more gently than that of the left. The table in fig. 1 sets the scoring presently adopted by J. S. D. F. against that by the five gradations method contrived with standard deviations obtained from the results of the study of the frequency distribution- Fig. 1. Frequency Distribution of P. R. after Load (Arm Stretch and Flection in Arm-Toe Position) (600 Cases) [figure] Fig. 2 shows the frequency distribution of the scores gained by means of Harvard's Step test. The table in fig. 2 denotes the percentage of the cases classified with the scores obtained according to Harvard's criterion. Then the men with "ordinary" bodily strength was counted up 87% of all. Fig. 3 shows the frequency distribution of so-called cardiopulmonary index, i. e. the scores obtained by means of Schneider's test. The table in fig. 3 exhibits the percentage of the cases classified with the scores gained accoring to Schneider's criterion. Consequently, it may be said that there exists some divergence of the gradations between the criterions of these three tests. Although the correlation among the scores of these three tests was closely investigated, Schneider's cardio-pulmonary index had hardly bearing upon any other two scorings. The study was made wheather the correlation between the pulse rates after J.S.D.F's test, the scores by Harverd's step test, and Schneider's cardio-pulmonary index exists or might stand no need of the estimation of the pulse-rate in recumbence separately in consideration of the variations of their extent. However, there could be recognized the reverse correlation between the pulse rates by standing and their increase due to the load-test, so that it may be necessary to score, the latter separately with regard to the variations of the extent of the latter. The recovery time showed the positive correlation to the increase in the pulse rates due to the load-test. Therefor in comformity with Schneider's estimation, the more the pulse-rates by standing increased, the less the percentage of the increase in the pulse rates due to the load-test and the shoster the recovery time were found, so that there could be seen the inverse results against those of the scoring with the use of the pulse-rates by standing. It may be still a quenstion that Schneider's test adopts only the absolute value without any consideration of the recovery of the pulse rates.
