It was the purpose of this investigation to establish a scientific method of training ski-players on which the authors had been studing, To study such method, it was assumed that the character of each player should be revealed by examining his physical capacity individually.
Fortunately, the authors had an opportunity to examine the physical fitness of 308 players from among about 700 participants of the 14th National Senior-High-School Ski Tournament (so-called Inter-High) held at the Shiga Heights, Nagano Prefecture, on February 5 to 8, 1965.
This report deals with the results of this examination. The items for measurement numberd 18: height, weight, sitting height, girth of chest, length of arm (right and left), length of leg, stretch of arm, max. girth of upper arm (right and left) extended and flexed, max girth of forearm (right and left), min. girth of forearm (right and left), girth of thigh (right and left), girth of calf (right and left), girth of ankle (right and left), skinfold thickness of the abdomen, pulmonary vital capacity, grip strength (right and left), shoulders and arms to push and pull, and back strength.
In this examination, physical measurement for the above items was performed by visiting inns scattered around the Shiga Heights where the players stayed after training. So that, it was too short of time to be perfect. There was also a limit for checking all the items on account of shortage of staff, as compared with the number of examinees. There is still something to be improved on the items themselves mentioned above.
The results of measurement are as follows. No particular relations were found among the items measured. When the best ten players were selected from each of the events and checked for the physical items listed above, there were no particular characters related to any of the events. It seemed in them that the playing techni que depended on the physical structure to some extent.
Besides, the ten poorest players were selected from each event and measured for the physical items listed above. As a result, it was found that there were outsan ding differences in some of the items between the best group and the poorest one. When pulmonary vital capacity was compared in the event of Nordik skiing, it was low in the best group than in the poorest one.
There is still a need for reexamining or developing the results of the present investigation in future. As for the results of the present inspection, the following two points should be taken into consideration : (1) The examinees were all senior high-school students, who are in the growing stage. (2) They were inexperienced in trainig for specialization into a particular event. In other words, they had had a comparatively short period of training, although they had played skiing for a ra ther long time.

The problems on the physical development of children in primary schools and middle schools were followed up from the view of Rohrer Index and Step Test Score, which was continued from our last experiment. The results are in the following
1) In the first year students of the middle school step test score did not decrease, even in the height of the step was enhanced and the subjects was made to have some load.
2) In the third year students of the middle school step test score decreased when the load increased.
3) The number of the subjects who showed over the sum (The average Rohrer Index+twice as much as the standard deviation), was more in the range of plus than in that of minus, and it was no relationship the with difference of a year.
4) Generally Rohrer Index had the decreasing tendency recently, but sometimes tremendously large Rohrer Index has been found.
5) The Rohrer Index in the latter of a third grade student of the middle school being compared with his former Rohrer Index, in the case of male students the corelation efficiency was found not in 7 years of age, but from 11 years of age, On the other hand, in the case of female students it was highly found in 9 years of age.
6) In the group that had had a circuit training programmed especially for them, the average Rohrer Index decreased in comparison with that of the control group. The degree of its decreasing was greater in the group that began to have their training at the time of the entrance to the middle school than in the group that began after the second year. Furthermore, training efficiency was much greater in the group of the small Rohler Index than in the group of the large Rohrer Index.
7) Concerned those three groups in the third year of a middle school, the group under Rohrer Index 100, the group of the Standard Rohrer Index and the group over Rohrer Index 100, comparison of step test score with blood pressure, there existed no significant difference in blood pressure. The group of the standard Rohrer Index was best at step test score, and the group under Rohrer Index 100 and the group over Rohrer Index 150 were inferior to the former group of the standard Rohrer Index. There was no difference between both two groups of the latter.
