    【Purpose】The purpose of this study was to clarify the relationship between grip strength and walking function, factors of falls, and health-related QOL in one-year change of elderly people at high risk for needing care.

    【Methods】A survey of grip strength measurement, walking function, factors of falls, and health-related QOL was conducted among high risk elderly people participating in a care prevention program and needing care who could roam freely. In order to investigate the relationship between falls and muscle strength, we measured grip strength, an index of bodily muscle strength. Walking variables such as stride length, swing speed, knee joint angle, heel joint angle, and knee position were analyzed through gait measurements and an evaluation system. The fall risk index and a fall prevention self-efficacy scale were applied to explain the fall factor. SF-8TM was applied to explain health-related QOL.

    【Results】The sample included 20 subjects (male, n = 4; female, n = 16). The average age was 80.7 (±6.4) years. The average baseline value of grip strength was 19.6 (± 6.5) kg, and the change in one year was -0.4 (± 2.1) kg. The relationship between grip strength of subjects and each index in one-year change was analyzed by correlation coefficients. The fall risk index was significantly negatively correlated with grip strength (r =-0.460, p<0.05). The general health (GH) measure from the SF8 Health Survey (SF-8 TM) was significantly positively correlated with grip strength (r = 0.530, p<0.05). Stride length and knee position (rear) from gait measurements and the evaluation system were significantly positively correlated with grip strength (r = 0.610, r = 0.540, p<0.05).

    【Conclusion】The results of this study revealed significant correlations between grip strength and stride length, knee position (rear), fall risk index, and general health (GH) in one-year change of elderly people at high risk for needing care.

    【Objective】Falling down is one of the problems for the children. Therefore, it seems important to instruct children on fall prevention exercise at the elementary school physical education classes. The aim of this study is as follows Focusing on preventing children from falling, we conduct dynamic balance exercises in the physical education classes and reveal the effect of this Exercises.

    【Methods】The subjects were 34 the 3rd graders students. We instructed them on four “wobble movement exercises” at physical education class 3 times in total (45 minutes each), and measured physical strength data for one-leg standing duration with vision, standing long jump and repeated side stepping before and after the instruction of the exercise. In addition, for the reflective analysis, formative evaluation of the lesson was performed.

    【Results】A significant difference was observed in the physical strength data for standing long jump and repeated side stepping before and after 3 classes. According to the formative evaluation of the lessons, furthermore, the evaluation level 3 or higher was obtained for all items in 3 classes that the classes were good ones for students. Especially, for “learning method”, the evaluation level 5 was maintained for all 3 classes.

    【Conclusion】The value of the standing long jump and repetitive stepping was improved by the wobbling exercise. And children's class evaluation has been high, it was shown that the physical education class aimed at preventing falls was a content of physical education in which children could voluntarily and happily learn.
