The present study was performed to see whether the growth of height and weight can be the condition of variety of flexibility and power. Chungnam Kational University students were chosen as objects for this study. Total number of objects were 130, who had been randomly selected. The followings can be presented as main findings of this study: (ⅰ) No significant relationship Iq-as shown between heigt and flexibility, or height and power. (ⅱ) No signifiacnt relationship between weight and power, or weight and flexibility. (ⅲ) No significant relationship between flexibility and power. (ⅳ) Significant relationship appeared between flexibility and physical size. (ⅴ) No significant relationship between power and physical size.

The present study was performed to see whether it has relationship between the height and weight of the body that is depended on the height and weight of the body and the variety of the pulse and breath in sports activities. Chung Nam National Univ. female students were chosen for study. Total number of objects were 116, who had been randomly selected. The following can be presented as conclusion. 1. Comparing with another group, university female students generally have the slender style of the body. 2. We can't discover the difference among the styles of the body on variety of the pulse and breath in general activities. 3. The fat style group was appeared as a group with the most frequency of the pulse and breath after sports activities. 4. The difference between the frequency of the pulse and breath before sports and that after sports was remarkable on the fat style group. 5. No significant relationship was shown between the style of the body and the variety of the pulse and breath, but a significant difference in the pulse and the breath can be shown between the normal style and the fat style if it's the heavy fat style.

To study the good movement state of the trunk twisting and the segment of the upper limbs to get the correct logn throwing distance, the author got the kinematic changing elements of the upper limbs movement by the screen analysis of the displacement, and the movement velocity of joints, angles of joints, spending hours, and the wheel tracks, selecting the skilled and the unskilled. 1. In the throwing at his position, when the trunk twisting was great, the shifting distance of the joints was longer, and had the natural track in which ending was gentle. 2. The vertical movement of the body had a deep relation with the trunk twisting in the throwing movement. 3. When the trunk twisting was very slow, the direction of the joint track was direct opposite to the quick twisting. 4. The time each track got out of the body and the shifting distance of the slowest joint velocity by the trunk twisting of the skilled, vertical shift, and the enlargement of the angle of joints coincided. 5. The spending hours of the throwing movement became longer as the trunk twisting was big, and the slowest joint velocity which preparing time is ended in the throwing movement was in the position around 60% of the total spending hours. 6. In the skilled person the appearing of the slowest velocity of each joints coincided among joints, and brought the late half velocity rising at the slower velocity (skilled : 5m/sec, unskilled : 9m/sec) comparing the unskilled person. 7. The time of the late half velocity rising and shifting distance had a deep relation with the velocity of a ball when it was released.

This study was performed to observe relations between physical fitness and the shape of the sole of a foot by selecting 300 elementary school children (ages 9-11) composed of 150 boys and girls, and their foot prints were used for this study. The result were as follows: 1. The amount of the growth of foot length is about 1 centimeter a year, but the growth of foot-width and calcaneus is not significant. 2. Girls have larger angle of a Hallux and a toe than boys, but smaller angle of a heel than boys. 3. The average angle of C.F.P.A is 35.69˚(for boys) and 37.53˚(for girls) 4. The normal shape of the sole of a foot was shown 45% among children and in proportion to the grade of abnormal shape, the rate decreased gradually (42.33%, 9.67%, 3%) 5. Elements of motor fitness which relates to C.F.P.A are endurence and speed. 6. The children with normal shape of the sole of a foot have more excellent motor fitness than those of abnormal.

The present study was performed to see the relationships between the abilities of physical activities and different field of knowledges. Young San high school students were chosen as objects for the study. Total number of objects were 190, who had been randomly selected. The following can be presented as conclusion. 1. Significant relationship was shown between the abilities of physical activities and the abilities of studies. But extra high lebel of relationship was not shown between the abilities of physical activities and a special subject of study. 2. Significant relationship was shown between active attitude in physical activities and efficancy, enthusiasm for studies. 3. Significant relationships were shown between the ability of music in accomplishments the ability of studies, and was shown between the ability of art and the abilities of language, literature except natural science. 4. Significant relationship was not shown between the abilities of physical actibities and the years of parents. 5. Significant relationship was not mown between me abilities of physical activities and the number of brothers.
