     This study aimed to examine the center of pressure (COP) sway characteristics during a static one-legged stance after a single-legged landing from a platform and the relationships between COP variation and static one-legged stance tests (with eyes open and closed). The pool of subjects included 16 healthy males (19 – 23 years). They were asked to hold a static one-legged stance for approximately 30 seconds after performing a single-legged landing on a force plate (Kistler, 9286A) from a 30cm height platform.  No significant differences between the preferred leg and the non-preferred leg were found with respect to any of the COP parameters over a time period of 3 seconds following the single-legged landing. No significant correlations between COP parameters and body weight were found (r=¦0.04-0.49¦). The trajectory lengths of the COP parameters over a period of 20 seconds showed high correlations with the trajectories of the COP parameters of a static one-legged stance performed with eyes open (r=0.71, 0.78).  From these results, it was determined that lateral dominance and body weight do not significantly affect the COP following a single-legged landing from a platform. When evaluating COP after a single-legged landing over a period of 20 seconds, it is believed that the trajectory length may have a strong relationship with the static one-legged stance.

     本研究の目的は,体格指数(BMI)および体脂肪率の判定基準に基づき,高専男子学生の肥満者の体力の特徴を明らかにすることであった.15歳〜19歳の健常な男子学生117名を対象に,体力測定を実施した.体格テスト(4項目)および文部科学省の新体力テスト(8項目)が利用された.生活習慣に関する8項目からなる調査を実施した.体格指数(BMI)および体脂肪率の判定基準に基づき,被験者を以下の3群に分類した:非肥満群(体脂肪率20%未満,n=59),過体重肥満群(体脂肪率20%以上で,且つ,BMIが25以上,n=32),および隠れ肥満群(体脂肪率20%以上で,且つ,BMIが25未満,n=26).平均値の差は,一要因分散分析を用いて検討された.各質問項目に関して,クロス集計を行い,3群間のカテゴリ間の度数の有意差を検討した.20mシャトルランは非肥満群,隠れ肥満群,過体重肥満群の順に有意に速かった.50m走タイムは,過体重肥満群と隠れ肥満群はそれぞれ非肥満群よりも有意に長かった.立ち幅跳びは,過体重肥満群と隠れ肥満群はそれぞれ非肥満群よりも有意に短かった.過体重肥満群の運動部参加者が有意に多かった.結論として,高専男子肥満学生に対して,適度な脂肪量の維持,あるいは筋収縮速度や筋パワーの向上についての適切なトレーニングや身体機能改善の指導が必要と判断された.

     There are few studies on the body composition of young children, and almost none that have investigated the relationship between body composition and motor performance. In the present study we conducted a correlation analysis of body composition and motor performance in young children, and attempted to provide basic information in relational compositions between the two. The subjects were 153 boys and 175 girls aged 3–5 years at kindergartens in the Shinshiro and Toyohashi areas of Aichi Prefecture. Body composition was measured using a Tanita MC-190EM body composition analyzer (multi-frequency, 8 electrodes), and included body weight, soft lean mass, body water, estimated bone mass, fat-free mass, body fat percentage, and fat mass. Significant increasing trends in height, weight, soft lean mass, fat-free mass, estimated bone mass, and body water were found for changes in physique with age of both boys and girls, indicating a clear growth trend. However, no clear changes with age were seen in body fat percentage and fat mass of boys or BMI of girls. In motor performance, significant increases were seen at each age in the 20 m dash, standing long jump, side steps, one-legged hop, standing on one leg, and tennis ball throw using equipment. In contrast, in items where equipment was used, measurements showed close to no development in jump rope and ball bouncing in 3 and 4-year-old boys. Findings for ball bouncing were similar in girls. In the correlation analysis of body composition and motor performance, significant correlations were seen between 20 m dash and height, fat-free mass, and fat mass in boys of all age groups. Among girls, however, there were no items in which significant correlations were seen in any age group. However, there did not appear to be clear correlations in the young childhood period overall. Thus, early childhood is thought to be a time in which natural growth and development is controlled congenitally and genetically, and physical growth and development is thought to be individual in young children.

     Purpose : In this study, we utilized the ICF, as proposed by the WHO in 2001, in order to analyze nurses’ and caregivers’ practices of care for the elderly.  Method : From these institutions, 500 nurses and 500 care workers were asked to answer questionnaires regarding care from the viewpoint of the ICF.  Result : Surveys were returned from 249 nurses (49.8%) and 284 care workers (56.8%). Within the domain of body function and body structure, nurses ranked infection prevention measures and regulation of elimination as most practiced. Care workers ranked infection prevention and bedsore prevention as most highly. Within the domain of activity and participation, both nurses and care workers ranked checking dietary intake as most practiced. Within the domain of environmental factors, nurses again ranked infection prevention measures as most practiced, and care workers ranked risk management as most practiced. For both nurses and care workers, there was a high correlation between the domains of activity and participation and environmental factors.  Conclusion : We believe the ICF-based tools developed in this study can be used in general situations as an indicator of whether daily care is provided in a manor appropriate and suitable for each patient.

     In this study, we investigated secular changes in growth velocity in the physical growth of infants and young children using the wavelet interpolation method, and examined the construction of secular trend in physical growth distance and velocity curve. The subject data were physical growth survey records for boys’ and girls’ infant and young children published by the Ministry of Health, Labor and Welfare in 1960, 1970, 1980, 1990 and 2000. The physical growth elements used in the study were height, weight, chest circumference, head circumference and BMI. The wavelet interpolation method was applied to these elements for the period from age 0 to 6 years, and the derived growth distance and velocity curves were analyzed. First, it was shown that the values at birth become gradually higher from 1960 to 2000 for both boys and girls, but that after 6 months of age the values for 2000 exceeded those for 1960. From the age at largest peak velocity (LPV) soon after birth, obtained from the analysis of the growth velocity curve, there were no findings that showed clear secular trend in either boys or girls. However, a clear gradually increasing trend was seen in the LPV for all items in both boys and girls from 1960 to 2000. The age at first local peak velocity (FLPV) remained unchanged in boys compared with the past, but in girls slightly earlier trends were seen in all elements. Thus, in the secular trend in the construction of physical growth distance and velocity curve in infants and young children, it was found that the amplitude of the waves detected in growth distance curve had become gradually smoother from 1960 to 2000.

     Using the Mental Health Pattern for Children (MHPC), a scale enabling two-dimensional assessment of negative and positive aspects of mental health, 121 elementary school children (grades 4-6) were studied to determine whether children’s mental health is different because of eating habits, physical activity, and the willingness to act. The following results were obtained. 1) Scores on positive aspects were significantly higher among boys than girls. Scores on negative aspects were significantly higher among sixth graders than fourth graders. 2) Children with desirable eating habits, especially related to breakfast, in terms of frequency, time, and menu, tended to have higher scores on positive aspects of mental health. 3) Mental health of two dimensions on negative and positive aspects of children who have or like chance of physical activity in daily life and play was excellent. 4) Health-conscious children were found to have good mental health with respect to both positive and negative aspects.  Our findings suggest that desirable eating habits, especially related to breakfast, physical activity, the willingness to act about health and health consciousness, help elementary school children maintain good mental health with respect to both positive and negative aspects.
