JOURNAL FREE ACCESSWas fur eine Bedeutung hat der Unterschied des Stoffproblems bei GutsMuths und Jahn? Als Schlussel der Beantwortung dieser Frage mochte ich in dieser Abhandlung vorwiegend die Uebungen der Sprachorgane und der Sinne beobachten. Diese zwei Uebungen gab es immer in europaischen diatetischen Leibeserziehung, von Hippokrates bid zur Philanthropen. GutsMuths behandelte auch diese Uebungen in seiner Gymnastik, aber Jahn nicht. Warum ? Auf diese Frage gebe ich in dieser Abhandlung damit eine Antwort, dass ich die diese Uebungen zu Jahn nicht ubernommenen Periode als einer Wendepunkt in der Geschichte der Leibeserziehung verstehe.View full abstractDownload PDF (627K) -

JOURNAL FREE ACCESSAlthough it is a well known fact that the pulmonary diffusing capacity is a key factor of aerobic work capacity, the available data are not sufficient for further discussion on basic training of endurance. The authors had conducted a series of measurement of pulmonary diffusing capacity for O_2 together with that of oxygen intake during the work. The work was given to the subjects on a bicycle ergometer with the load of progressively increasing up to nearly the maximal level. The subjects were chosen from ordinary healthy males and trained middle and long distance runners. To determine the pulmonary diffusing capacity, Filley's steady state method was used. And for oxygen intake, Douglas bag method was adopted using Scholander's apparatus. The results were as follows : (1) The pulmonary diffusing capacity for oxygen at rest was observed to be 22.3 and 32.4 ml/min/mmHg in ordinary and trained subjects respectively. (2) The pulmonary diffusing capacity for O_2 was increased together with the oxygen intake during the work. The regression lines were presented as follows : Y^^⋀=8.83X+22.07・・・・・・・・・・・・for ordinary subjects Y^^⋀=8.32X+32.36・・・・・・・・・・・・for trained subjects where Y^^⋀ showed diffusing capacity and X showed oxygen intake. (3) A close relationship was found between the maximum oxygen intake and the maximum diffusing capacity for oxygen with a correlation coefficient of r=0.817. (4) Based on these results, it is supposed that the pulmonary diffusing capacity will be increased during the work as one of the contributing factors of aerobic work capacity.View full abstractDownload PDF (958K) -

JOURNAL FREE ACCESSThe mechanical property of the relationship between force and velocity (F-V) was studied on leg extensor in child, adults and athletes by isotonic load apparatus mentioned in previous report. The results were as follows : 1. The maximum velocity of child was 75.5% against adult and 22.2% in maximum isometric strength. It's difference of F-V relation became greater with increase of force (load). 2. Jumper showed higher maximum mechanical power in average than that of sprinter, however, the maximurn velocity and the maximum strength of jumper were lower than sprinter. 3. It is of interest that jumper showed higher ratios of force against the maximum strength and his body weight than those of sprinter at just point of the maximum power, which values are the same for both subjects. However, sprinter showed higher ratio of velocity against the maximum than that of jumper. 4. Excellent performer showed higher power and isometric strength than those of average gymnasts. 5. The maximum strength, maximum velocity and maximum mechanical power of athletes of various kinds of sports were studied and compared with each other on male and female.View full abstractDownload PDF (740K) -

JOURNAL FREE ACCESSIt is very important for health instructors to get some imformations on when each pupil will have the first menstruation. The significant relationships between sexual maturation and anthropometric measures have been realized in many studies and also in our studies. Therefore, the prediction of first menstruation with anthropometric and growth speed measures was attempted in this paper. Two hundred junior high school girls who all experienced their first menstruation already were used as the sample. The predictor variables are as follows; stature, body weight, chest girth, sitting height, and growth speed measure, which were computed in (growth amount per a year) /1O in the four anthropometric measures. The sample was classified into four groups ; the first whose menarche ages were later than 10 years of age, the second later than 11, the third later than 12, and fourth later than 13. Let R_<12> be the row vector of correlations of menarche age with the predictor variables and R_<22> be the correlation matrix of predictor variables, so the coefficients of prediction formulaes were given by R_<12> R_<22>^<-1>X, where X stands for the column vector of predictor variables. Then, the prediction formulaes were investigated with such simulation technique as dropping the variables which showed minimum in the products of β-coefficient and correlation of menarche age with prediction variable and also with evaluating the multiple correlation. After all, for the second group, the prediction formula with all variable ( 8 anthropometric and 8 growth speed measures) showed the multiple correlation of 0.942, the one with 15 variables, excluding the stature of 6th grade, 0.902, and their 95% error of estimate were ± 0:541 year, and ± 0.715 year, respectively. The prediction formulaes for other sample groups were constructed, too, but they did not show good precision enough to be applied. Therefore, it can be concluded that prediction of menarche age with anthropometric measures of 5th and 6th grade is most effective. And it was proved that there were little error between the actual menartche age and the predicted one in other sample.View full abstractDownload PDF (708K) -

JOURNAL FREE ACCESSFor kindergarten children, authors constructed the special exercise-program graded in seven courses. In this program, various movements, as running, jumping, rolling, throwing, pulling, hanging, and climbing, are included. According to that program, we taught physical exercises to kindergarten children during three months, and measured effects of exercise about standing posture, walking form, and motor ability. The results were as follows ; 1) Children were much interested in that exercise-program, and showed remarkable progress. 2) These exercises were very effective to the development of good posture, walking, and motor ability.View full abstractDownload PDF (926K) -

JOURNAL FREE ACCESSThe purpose of this study was to investigate the change in urinary excretion of 17-KS due to 1O,OOO m running. The subject was a 21-year old healthy male. First a diurnal variation of 17-KS in control days was studied, and then that in 10,000m running days was done. Each running was started just after the urinary collection 7a.m.-11a.m. The subject had been instructed to empty his bladder at 7a.m. Urine was collected over a 24-hour period in five lots covering the periods 7a.m.-11a.m., 11a.m. -3p.m., 3p.m. -7p.m., 7p.m. -11p.m. and 11p.m. -7a.m. Specimens of urine were stored at 5-10℃ and the steroids were estimated within 48 hours after the collection. The method employed to estimate 17-KS was essentially that reported by Drekter (1952). The results were as follows ; 1. In control days, the urinary excretion of 17-KS was the maximum in the period 7a.m. -11a.m or 11a.m. -3p.m. and fell to the minimum in the period 11p.m. -7a.m., though that in the period 7p.m. -11p.m. rose a little. 2. In running days, the urinary excretion of 17-KS was the maximum in the period 7a.m. -11a.m. and dropped off slowly thereafter. 3. Compared each lot of running days with that of control days, the urinary excretion of 17-KS in the former was generally greater than that in the latter, especially in the pariod 7a.m. -11a.m., 3p.m. -7p.m. and 11p.m. -7a.m. 4. From the above, it may be concluded that the physical and mental stress of 10.000 m running caused the increased urinary excretion of 17-KS.View full abstractDownload PDF (870K) -
