The observations were performed in autumn in 100 rats at the age of 1 month. The animals were trained in a horizontal treadmill with the speed 40 m/min, beginning with 3 min/day and gradually increasing the time up to 30 min. The control animals were not trained, the test animals were trained either once a day (at 7 a. m., 3 p. m., 11 p. m.), or three times a day and the total loading was equal to a single loading. The animals were weighed daily. Elongation of the bones, increase in their mass and in the body mass were different at training during different time of the day and the effect was not similar in different bones. Certain sexual differences of the training effect were revealed.
观察在秋季对100只1月龄大鼠进行。动物在水平跑步机上以40米/分钟的速度训练，从每天3分钟开始，逐渐将时间增加到30分钟。对照动物不进行训练，试验动物每天训练一次（上午7点、下午3点、晚上11点），或每天训练三次，总负荷量等同于单次负荷量。每天称动物体重。一天中不同时间训练时，骨骼的伸长、骨骼质量和体重的增加情况各不相同，且不同骨骼的效果也不相似。揭示了训练效果存在一定的性别差异。
