The objective of this study was to collect basic data of coordination abilities in early childhood. The targets of analysis were 171 children (86 boys and 85 girls) between the ages of 5 and 6 attending public daycare centers in Aichi Prefecture and their 171 guardians. A direct assessment of coordination abilities was used on the children and a questionnaire survey on motor coordination, the Japanese version of the Developmental Coordination Disorder Questionnaire (DCDQ-J) was conducted on the guardians. Based on the results of the coordination ability assessment and the DCDQ-J, the following findings were revealed in terms of coordination abilities associated with coordinated movement in children:

1)　 When coordination abilities were measured, there was a difference among year groups and between genders. This suggested that there is a gender difference in the developmental process of each of the components of coordination abilities.

2)　 The results of cluster analysis showed that the properties of motor coordination in early childhood can be divided into four subgroups: a group that i) dominant of fine motor skills; ii) excels in motor coordination skills; iii) recessive of fine motor skills; and iv) struggles with motor coordination skills.

3)　 As “side-to-side jump” and “throw-and-catch a ball” were associated with the properties of motor coordination, the evaluation of coordination abilities in coordinated movement was greatly affected, especially by time and spatial factors of orientation, differentiation and balance abilities.

  As a result of declining birth rates and the increase of nuclear families, there are fewer opportunities in modern society for children of different age groups to interact in the home and in the local community. Under such circumstances, it is important for children to develop relationships and communicative competence with their friends at school. To that end, the author believes that encouraging children to participate in different age group activities will lead to increased confidence and peace of mind, resulting in positive and safe interactions.

  In this study, the results of different age group activities from previous research were reexamined and reassessed. It was hypothesized that different age group activities undertaken by the whole school would foster good human relations and positively influence children’s awareness of risk management and safety.

  Based on this hypothesis, the results of an education survey of, 19 major cities (the most populated cities officially designated by the government) and a health statistics (hoken-shitsu) were compared. Several small-scale elementary school surveys were also analyzed. Based on this analysis, it was found that through activities that included various different age groups, good human relations could be developed. These activities were especially effective in raising the children’s safety awareness as well as improving their risk management abilities.

  The aim of this study is to clarify the relationship between the subjective health (health-related QOL, stress, unidentified complaints) of mothers and the physical fitness of children. Elder children that took physical fitness tests,and whose mothers answered Questionnaires. Mother and child who cooperated both were 103 sets. Ttest was carried out between each scale of maternal health and each result of children’s physical fitness.

  The results showed that １) there are no significant differences in any of the categories relating to the health of mothers with boys and 2 ) it is suggested that, for girls, between body support and stress, catching and unidentified complaints, seated forward bends and unidentified complaints, standing long jump and stress, unidentified complaints, continuous multiple object jumping and stress, the results were that the mother’s stress and unidentified complaints were low if girls’ physical strength performance was good. However, in relation to health-related QOL mental health and standing long jump performance, it was confirmed that results showed low mental health in those in the group with good performance and it was clarified that there was not always necessarily a direct relationship between the mother’s health and the physical strength of girls. In the future, it is necessary to investigate the relationship between the health of the mothers and the physical strength of children including other diverse factors.
