    This study was to investigate the effects of exercise experienced in youth on the genital function from menarche to menopause. One thousand and seven females after menopause aged from 45 to 88 completed the questionnaires. The results were as follows.
    1) The age of menarche became significantly younger as years went on.
    2) Females who had exercised in youth was significantly ahead of those who had not exercised in youth in menarche. The age of menarche was significantly earlier in more exercised group than in less exercised group.
    3) The frequency of pregnancy and delivery became significantly lower as years wore on.
    4) Although the period from menarche to menopause tended to get longer, there were no effects of the exercise experienced in youth on it.
    5) There were no effects of the exercise experienced in youth on the age of menopause and menopausal disorder.

    To study the development of static behavior of disabled schoolchildren, 20 items of behavior were checked in 145 children from the two schools for the mentally retarded. The items are kneeling, cross-legged sitting, legs forward bending and touching the toes, opening toes, hands together on the back, etc.
    Each item of behavior was given 1 point if succeeded or 0 if failed. The items were 20 in total, so 20 points were given if all items were succeeded.
    The average score for senior high school students was significantly higher than for junior high school students, and that of elementary schoolchildren was the lowest. But there was no significant difference between male and female. The static behavior seems to be affected more seriously by disability than by sex difference.
    The static behavior of disabled schoolchildren developed sequentially from a kind of coordination to the intellectual one.

    In this paper, the development of body-awareness of children in the kinder-garten; body drawings, recognition of body parts and body action expressions of 3-year-old preschoolchildren were studied. The following are the findings.
    1. There was a marked individual difference in the recognition of body parts, varying from the highest score; 19 to the lowest score; 7 out of 21 body parts.
    2. As for the expression of body action, “waving one's hand” was recognized 62%, “bending over”; 12%, “bending one's knee”; 44%, and “bending one's arm”; 22% in later-half-3-year-old boys.
    3. In comparison with the Development Process of “Human” by Rhoda Kellog, those body drawings showed a marked variety from something like a scribble to rather a complete human image.
    4. The body drawings occupied a bigger drawing area, and the scores were also higher at the body drawing B than the body drawing A.
    5. No correlation was found among the drawing area size of body drawing, physical characteristics such as height and weight, and body parts.

    The purpose of this study was to investigate some developmental characteristics of horizontal target jump in children. The subjects of this study were a hundred twenty nine boys aged from four to six. Targets for horizontal target jump were set as follows: 40%, 60% and 80% distance of each subject's longest distance in standing long jump. The error in target jumping was measured and analyzed from the viewpoint of age, standing long jump distance and jumping pattern level.
    The rapid development of horizontal target jump was observed among the subjects of 5 years of age, those who could jump over 80cm and those who were able to perform jumping in the pattern of level 3. It was also observed that the accuracy in target jumping improved from the stage influenced by the ratio of target distance to the stage not influenced.

    For the purpose of studying the difference of development of jumping skill in schoolchildren in the different kind of exercise environment, the motion of standing long jump was analyzed by the method of Developmental Biomechanics (Kinesiology). Subjects were 6, 8, and 10-year-old children in the Republic of Honduras and in Japan. The experimental group in Honduras participated in the Japanese style program of physical education for 2 years, and the other control group in Honduras did not take any program of physical education.
    Results of performance test, evaluation of jumping pattern, and motion analysis indicate that the skill of standing long jump of Japanese children ranked at the highest level followed by that of the experimental group and the control one, and that the development of skill was reflected in the excellent performance in Japanese and the experimental school children. In the control group, no remarkable difference was recognized among the skills of 6, 8, and 10-year-old children, and the difference of performance test score among age groups was supposed to be brought from the growth of physique and/or physical resource.

    The purpose of this study was to examine the movement pattern during a rhythmic movement in preschool children focusing on the coordination of upper and lower extremities. Children were tasked to swing upper limbs with knee bending rhythmically, in three kinds of tempo: 120, 96 and 60bpm. For the analysis of the movement, the angular velocity of shoulder and knee were calculated from VTR images.
    In mature pattern, the changing point of movement direction of upper extremities slightly preceded that of lower extremities. Peek velocity of the shoulder angle appeared at the moment of the deepest knee bending, which meant the moment of upward-changing. And irrespective of the tempo, the movement sequence did not change in adults movement. On the other hand, the movement patterns of children changed with tempo. Particularly, under the slow tempo, their movement patterns varied with those tempos. It was suggested that children had not programmed spatial-temporal patterns of their movement in advance.
    The older children were superior to the younger, and girls to boys in the movement task.

    In this paper, the movement tempo was studied by checking various patterns of human quadrupedal walking in terms of tempo. The subjects were 10 children aged 5, and 10 adults. “Creeping on hands and knees” and “walking on hands and feet”, were tasked freely at first, then with the auditory stimuli; 60, 80, 100, 120, 135, 150/60second. Typical patterns of free walking appeared in stimuli 100 for “creeping on hands and knees” and 120 for “walking on hands and feet” in adults, and 100 and 120 for “walking on hands and feet” in children. It can be considered that each human movement has its own suitable tempo.
