In the current study, the effect of the weight body index (WBI) on the walking function of university students was investigated, with 45 male general university students as the test subjects. For each subject, left and right knee extension strength was measured and the mean was divided by body weight to calculate the WBI. Wearing a pedometer, each subject performed fast walking with maximum exertion for 400 m, customary walking felt to be the mode of walking in daily life, and slow, leisurely walking at a freely chosen speed. Assessment for a relation between WBI and walking function (walking speed, step length, and cadence) in these three walking modes showed a correlation of both walking speed and step length with WBI (each p=0.01, p=0.00) in the fast walking mode, in which step length apparently had a greater effect on walking speed than cadence. In the customary and leisurely walking modes, no correlation was found for any of the parameters. The results thus indicate that in investigating the walking function of university students, observation of fast walking rather than customary walking speed is desirable. Further study will be necessary to elucidate relations between the various elements of physical strength and fast walking.

The purpose of this paper is to take an important case on school PE accident and look at it in detail. It is to present materials to consider the teacher's "at that time", "there" and "what". What reasons did the court who finished examining evidence such as plaintiff's argument, defendant's objections judge the suitability of each argument? I examined underlined parts that I added. As a concrete example, confirm the range of teacher's duty of care in the physical movement (mat movement) of PE lessons at public high schools.

In this paper, we first outline what type of body PE we have been trying to foster. And think again what kind of body the future PE should cultivate. The purpose of this paper is to reconsider something in the first place what PE should be aimed at, and to clarify how to capture the body that PE should be a goal.
