<I>Problem</I>: A survey of the literature about the warning-up effect shows that most of the experinlenters have used as their experimental materials some form of work such as tapring, multiplication, additon, memorizing etc, but we can find few results in the work of muscular strength. It is the warming-up effect in Such Woirk, therefore, that we will discuss first in this paper.<BR>The literature also shows that, all investigators have not agreed in the problem of the relationship between the warming-up effect and the effect of practice. In this point we find the second problem, that will be treated here.<BR><I>Proceaure and Result</I>: For the first problem we measured the strength of grip of the right hand with the hand dynamometer after Smedley. There were four conditions in this experiment as follows;_??_<BR>The warming-up effect was clearly demonstrated in every condition of our experiment, and it was noted at once that the shorter the rest period was, the later the effect in question appeared.<BR>The warming-up effect was greatest in condtition IV, and in this case the subjects introspected some "feeling of expansion" in their arms. And there were individual differences at the time when the warming-up effect appeared.<BR>We experimeted also with tapping under the same conditions, and found the same results mentioned above.<BR>For the second problem we tried practice experiments with Kraepelin's addition, standing broad jump, grip and tap. The addition was practiced by four subjects about seventy days in the condition of 5' work, 5' rest, 5' work.<BR>At the earlier period of practice the second 5' work was always better than the first 5' work, but at the later they became reverse, that is the first 5' work gives no positive effect to the second 5' work. The positive effect of the earlier period, therefore, may be considered not to be the warmingup effect, brit the effect of practice.<BR>In other tests the positive effects of the works before the rest periods, upon the works after the rests were always found, and the greatest warmingup effect grew to appear earlier with practice.<BR>Oehm and Heron using nonsense syllables, found the warming-up effect to be present. Thorndike, however says of the former's work, that there was little or no direct evidence of warming -up in his records, and Mitchell indicated that the alleged warming-up effect in the later work must be regarded as the effect of practice. Present writers found the same thing in adding experiment. Therefore we can conclude that in such more mental form of work, the warming-up effect is not clearly demonstrable, but in more muscular form of work such as tapping, strength of grip, standing broad jump etc, we can see the effect clearly.
