    焼津地区の小中学生の身体計測, 筋力測定並びに運動能力テストを行つた結果大要次のような成績を得た。
    1) 同県修善寺地区に比較して体型はずんぐり型である。長育及び幅厚育の年令別増加率は修善寺地区と殆んど同じであるが, 比上肢長値が高学年になつて増加してくる点が異つており, 長管状骨発育の遅れが推定される。
    2) 幅厚育値及び筋力も一般的に修善寺地区より劣つている。
    3) ステップテスト点は6~11才までは年令差も性差もなく65~70点である。男子では12, 13才でも11才以前と同等であるが, 女子では12, 13才は著しく低下55点前後となる。14才では男女ともそれ以前に年令よりもすぐれた値を示し75点前後となる。女子12, 13才の著明低下は比体重値及び体重/下腿囲比の当年令における急激増加と関係があると推定され, 13才以前の児童におけるステツプテスト点の意味は下肢筋群に対する重量負担度の凾数的なものが主であると思われる。
    4) 時間肺活量の1秒率, 2秒率, 3秒率には6~14才の範囲で性差, 年令差は認められないが, 1秒率は成人値より称々劣つている。最大呼出速度の原法による測定法を11才以下の年令に摘用することについては疑問がある。
    5) 垂直跳は男子では年令と共に増加するが女子では11才以降あまり増加しない。
    6) 懸垂屈腕回数, 懸垂持続時間いつれも男子では年令に従い増加するが, 女子の懸垂持続時間は12才以降に低下する。
    7) 懸垂持続時間×体重値の6才から14才までの増加率は女子は男子の約2/1である。
    8) 垂直跳×体重値の6才から14才までの増加率は女子は男子の約3/2である。
    9) 運動能力性差は13才以降で著明となる。

    The differences between glucose and sucrose were investigated on their effects of the recovery process after exercise.
    After 17 hours fasting, male rats weighted 100-150g were forced to swim for three hours in 30°C warm water. Twenty percent solution of glucose or sucrose were administered orally by a stomach tube after the exercise.
    Results were as follows;
    1) Low blood sugar levels caused by severe exercise were reduced by administration of sugar and hyperglycemia continued more than three hours, while the maximum blood sugar level in non-exercised group was shown at one hour after administration and it decreased to normal value by three hours.
    2) Although there was very slight sugar left in digestive tract (stomach to ileum) at one hour after glucose administration, delaying of sugar absorption was remarkable in sucrose administered groups ; that is, 125.2 mg% and 20.9 mg% of sugar were measured at one and three hours, respectively, after giving of sucrose.
    3) Glycogen contents in liver and muscle increased more than that before the exercise in glucose administered groups by three hours after swimming. The recovery was not remarkable in sucrose administered rats, especially in liver.
    4) Total protein concentrations in serum were kept almost the same in all groups. Transaminase activities (GOT & GPT) in serum were increased slightly after exercise, however, lactic dehydrogenase activities were decreased. No special changes in enzyme acitvity of serum were found amoung the experimental groups treated with sugars.

    To reveal the limiting factors in endurance running on the treadmill was the main interest in this study. An excellent Japanese long distance runner who later got the third place at the Olympic marathon race in 1964, K. Tsuburaya, 23 served as the subject.
    The all-out running time, heart rate, respiratory rate, pulmonary ventilation and oxygen intake were measured when he ran at the two different speeds, 260m/min. and 240m/min., on the treadmill with 8.6% slope. From these measurements tidal volume, oxygen removal and oxygen pulse were calculated. The all-out running time of this subject was found to be 6 minutes 58 seconds at the speed of 260m/min. and 21 minutes 09 seconds at the speed of 240m/min.. The heart rate and respiratory rate were increased during running toward the point of “all-out”. It is worthy to note that the respiratory rate showed an abrupt increase near the point of exhaustion accompanied by decrease of tidal volume. The oxygen removal, the raito of oxygen intake to pulmonary ventilation, was also decreased gradually during running until it decreased to about 35 near the point of “all-out”.
    It was supposed from these results that the decrease of efficiency of respiratory function might play a big role to limit the endurance for running. It should be, in the next step, decided whether this decay of efficiency of the respiration would be caused by decreased cardiac output or uneven distribution of gas in the lung.
