Outline of Final Research Achievements

This study investigates the lifestyles of young children, and measures physique and hand grip strength, motor ability, and attempts to analyze actual living conditions, physical condition, physical fitness levels and motor ability of children living in a night-type society. Analyzing these relationships, we found a number of problems young children are encountering and made proposals for childcare and child rearing improvements of life rhythm for administration, preschool and families.
About 20% of sleeping children are going to bed after 10 p.m., and about 70% of young children cannot secure the 10 hours of sleep or more necessary for infants. Since bedtime has a significant influence on the life of a child the next day, it is important to move bedtime earlier and it is suggested that it is necessary to consciously incorporate physical activities to increase the amount of activity during the day and this should be executed immediately.
