To investigate the relationship between age at beginning of training, onset of menarche, distance for training of running, and lumbar bone mineral density (LBMD), twenty-six female long distance runners aged 18years old and above were examined. Runners suspected primary amenorrhea were excluded in this study.Runners who started training before menarche were delayed their onset of menarche significantly. The age at onset of menarche was selected as determining factor for LBMD, and was significantly negatively correlated to LBMD. It should be important not to delay menarche for preventing low LBMD in female long distance runners.

[Purpose] The purpose of this study was to examine the characteristics of physical fitness, lifestyle, and appearance of unidentified complaints in young children exhibiting hyperactivity and impulsive behavior. [Method] The subjects of this study were 628 young children. We analyzed 21 items related to children's behavior, lifestyle, and unidentified complaints, and 5 physical fitness items. We used these items to compare normal young children and young children exhibiting hyperactivity and impulsive behavior. [Results and Discussion] The proportion of young children exhibiting hyperactivity and impulsive behavior was slightly larger than that in the preceding research. From the results, it seems that a considerable number of children who were not medically diagnosed exhibited hyperactivity and impulsive behavior. In addition, it was confirmed that the lifestyle of these young children was significantly unhealthier than that of normal young children. We think that young children need assistance in order to ensure both appropriate behavior and lifestyle. It is necessary to examine the influence of these behavior and lifestyle upon physical fitness in older children.

Previous studies have shown that the use of a baby-walker during the first year after birth of a baby, when the motor skill is most significantly developed, may affect the subsequent development of the child. However, since trends in use of other infant equipment have not been investigated, it is not clear what kind of infant equipment is used at each stage of the infantile development. The present study was usage survey of infant equipment, including those other than baby-walkers, for newborns and infants during their first year of life. The survey was conducted by means of a questionnaire targeting 612 infants in Hyogo, Okayama, and Tottori prefectures in Japan, resulting in 307 valid responses, which have revealed their usage of infant equipment. Some items of infant equipment that are used for a longer time than baby-walkers may restrict infant. While the infant equipment increases the safety of the lives of infants, our data suggests the possibility that those devices may also limit their self-directed, which is important for gross motor development.

[Purpose] We examined the appropriate physical fitness level related to lifestyle and motor ability for kindergarten children. [Method] The subjects were 152 kindergarten children. The measurement items were physical activity (7 days) which was measured by pedometer, a fitness test (9 items), and a lifestyle questionnaire. [Results] The weekday average walking steps were 11,482±4,065 steps in a day (Boys : 12,354±4,308, Girls : 10,742±3,693), and half of the daily steps were counted during kindergarten activities in a day. The kindergarten children who have good lifestyles walked 12,531−13,558 steps in a day. The motor ability of the kindergarten children who had taken more than 13,000 steps daily was significantly better than that of other children. However, we should pay attention to the difference of the average steps of each school year because the result of the analysis of covariance for school year was not significant. The motor ability of the kindergarten children who had taken more than 6,500 steps after kindergarten activity was also significantly better. [Discussion] The results suggested that more than 13,000 steps daily, and more than 6,500 steps taken after kindergarten activity, constitute an appropriate level of physical activity for kindergarten children.

The purpose of this study to examine the difference in physical fitness levels among young children from the age of three until the age of five. The study analyzed data obtained through a pursuit measurement of the same subjects conducted for a period of three years. The subjects were 206 young children(104 boys and 102 girls)with standard physiques. We administered physical tests comprising seven types of exercises to understand their physical fitness characteristics;the tests were conducted every year in November for three years. Finally, the subjects were divided into the upper-ranking group(20%)and the lower-ranking group(20%)on the basis of the results of the physical tests at three-years old that corrected the age;further, the extent to which the difference between the two groups changed after two years was examined for each type of exercise. To conduct a statistical analysis of the data, a two-way ANOVA and the multiple comparisons(Tukey's HSD test)were employed. The analysis revealed a significant difference between the two groups for all types of exercises(in the case of both boys and girls). The gap reduced with each passing year for the side-step, 25-m run, and sitting trunk flexion. The exercise types for which the gap reduced until the age of four were grip strength and standing long jump. In the case of softball throw and upright hand standing time, the gap reduced until the age of four and then increased at the age of five. However, the gap did not reverse at the age of five for any exercise type. The level of physical fitness at the age of five remains strongly influenced by that at the age of three. The results suggested that the gap in the physical fitness among Japanese pupils has already begun to be observed in young children.

Introduction : Many studies on motor development in young children have been done using quantitative data obtained from motor performance tests. To understand motor development in young children, the development of the actual motor pattern producing the performance should be investigated and evaluated. The purposes of this study were to examine the development of seven different fundamental motor patterns (patterns of running, jumping, throwing, catching, ball bouncing, forward rolling, and moving on a balance beam) using an observational evaluation method, and to compare the acquisition situations of the fundamental motor patterns of young children in the recent year and in 1985.Method : The subjects were 154children (81boys and 73girls) from three to five years of age in 2007, and 123children (59boys and 64girls) in 1985. Their fundamental movements were recorded by video camera and evaluated by an observational method using five typical developmental stages of the motor patterns in each movement. Based on the results of analysis of these seven fundamental motor patterns, an index to understand the development of fundamental movement in early childhood overall was established as a “motor pattern development score”.Results : It was shown that the motor patterns of the seven fundamental movements in recent young children remained at an immature movement development stage, such as pattern 1 and pattern 2. A significant increase was seen with age in both the individual motor pattern scores for the seven movements and the motor pattern development score. Moreover, it was shown that the motor pattern scores of resent young children were below the scores of young children in 1985 in the seven kinds of movements in both boys and girls.Conclusion : The results of this study, showed that the acquisition of the fundamental motor patterns in resent young children was at a lower developmental stage than that of young children in 1985. It was also shown that the acquisition of fundamental movements in resent five-years-olds was similar to that of three-years-olds in 1985.

Current of 21st century, in Demawso area, Kayah state, Myanmar, there are living Kayan women, so-called “Long neck tribes”. They go through their daily life wearing long neck rings and ankle rings for their entire lives.In this research, we investigate the influence on growth shape wearing neck ring. We compare women group who wear neck rings (wearer group) with group who do not wear neck rings (non-wearer group) in Demawso area, Kayah state. The result are as follows, comparing the neck length of both groups in each age group.1. Wearing neck ring begins from childhood, and it continues all through their lives.2. There is no wearing influence from childhood to early part of adolescent period.3. It starts to appear the influence of wearing neck ring from “age 11 to under 15 age group”, which we call it early part of adolescent period.4. From “age 21 to under 30 age group”, the difference between two groups have increased tremendously. The value t shows t0=2.703. We observe the significant difference of average value between the two groups.5. From 30's onward, statistic significant difference could be detected in both groups.6. In “Over age 60's”, neck length of “wearing group” is 12.18 cm. It is the longest length among all the age group. Neck length of “no-wearing group” is 7.65 cm, and the gap between “wearing group” and “non-wearing group” is 4.53 cm, and this gap is the biggest in all age group.7. When height reaches the 140 cm at the early part of adolescent period, they wear much extended neck rings, and it will make big influence to growth & form afterward.Considering the results mentioned above, we have investigated the influence on growth wearing neck ring in each age group. Wearing neck ring has big influence on the shape of women neck. In the near future, our research could be the valuable evidence for judging the matter of wearing neck ring.

The purpose of this study was to examine factors related in past sports experiences before adulthood for developing exercise habits during adulthood. The participants were eighty adults aged 44-79(24 men:67.6±6.2 yr, 51 women:59.2±8.2 yr, and 5 unknown:69.7±4.5 yr). All participants belonged to a community club with sports and culture classes. Survey items included past sports experiences, current exercise habits, and enjoyment of exercise. Influences of past sports experiences to current exercise habits were examined using a multiple indicator model in structural equation modeling. Results for a causal structure model of past sports experiences and current exercise habits indicated a good fit to the data(CFI=0.998, RMSEA=0.030). The path coefficient was 0.34(standardized solution:past sports experiences→current exercise habits). However the path coefficient of past sports experiences→current exercise habits in the model which added enjoyment of exercise indicated a low value(-0.08, ns). Meanwhile, the path coefficient of past sports experiences→enjoyment of exercise and enjoyment of exercise→current exercise habits were 0.56 and 0.62, respectively. In addition, there was a no significant difference in physical activity level between numbers of sports experiences. These findings suggest that past sports experiences before adulthood had directly a stronger effect on enjoyment of exercise than on exercise habit, and that enjoyment of exercise had directly a strong effect on exercise habit.

This study aimed to verify the achievability of various motor tasks using a children's ladder according to age level in preschool children, and to examine the relationship between motor tasks and fundamental motor ability. The subjects were 625 preschool children (300 boys and 325 girls) aged 4 and 5 years old. They performed nine kinds of ladder tasks and fundamental motor ability tests (20 meter dash, standing long jump, tennis-ball throw, and beam cross-jump). There are significant differences between the achievement rates of both age groups in all motor tasks. The 5 year old group showed higher values than the 4 year old group. The achievement rate of a quick skip was the low in both age groups. It was suggested that the relationship among motor tasks differs largely in both age groups from verifying correlations ; these figures being higher in the 5 year old group. Because the nervous system functions coordinating movement develops markedly between the ages of 4 and 5, this relationship may increase with age. Multiple correlations between the total score of motor ability and the nine ladder tasks were significant in both age groups (4 yrs : 0.547, 5 yrs : 0.502, p<0.05). It was suggested that the contribution of the “open-close jump” to the fundamental motor ability is substantial. Partial correlations for the “open-close jump”, “quick skip”, and “zigzag jump” were large in the 4 year old group. The scores for the “quick skip”, “twist jump”, and “lateral dash” were greater in the 5 year old group. It is therefore concluded that these motor tasks are effective in improving the coordination ability of today's children.

Floating toes have been a suspected cause of falls and are thought to affect foot form and exertion of toe muscle strength. This study examined foot form and toe muscle strength in children with and without floating toes. The subjects were 372 boys and girls aged 5-10 years old. We measured their height, weight, toe muscle strength, foot length, foot width, heel width, center of gravity position, and the internal and external arches of both feet. Floating toes were found in 17.4% of the boys and 10.9% of the girls and occurred most frequently with the fifth toe in both sexes. No significant differences in age, physique, toe muscle strength, or foot form were found in the groups with and without floating toes, suggesting that floating toes are neither related to foot form nor to toe muscle strength.

The aim of this study was to investigate the relationships between cognitive functions and daily physical activities in primary school children. Subjects were 153 pupils (Age 6-12 years old), and visual Go/Nogo task for cognitive functions and parents questionnaire for daily physical activities were used.As results, male children exhibited negative correlation between duration of exercise and information processing time, and positive correlation between duration of exercise and the number of false response. Female children exhibited positive correlation between time of indoor play and number of false response. All these correlations were statistically significant. Further in females, those who spent longer time in playing video games exhibited statistically shorter reaction time.These findings suggested that the cognitive functions evaluated from visual Go/Nogo task were related to daily physical activities, especially the exercise and the indoor play. Further these factors and relationships could be different between males and females in preadolescent children.

This study evaluates the agility of preschool children by measuring simple reaction time and repeated sideways jumps. It also examines the influence of video games and exercise on development of the agility. The subjects were 636 preschool children(315 boys and 321 girls)aged 4 to 5. They performed the simple reaction time test with light stimulation and the repeated sideways jump test for five seconds. The agility score was calculated from the total T-score of both agility tests. This study investigates video games and preferred play time for the benefit of parents and nursery school teachers. The test results show that 37.6% of the 4-year-olds and 36.5% of the 5-year-olds frequently played video games and 57.1% of the 4-year-olds and 61.0% of the 5-year-olds showed a predilection for whole-body dynamic play(tag, jump-rope, dodge ball, etc.). The 5-year-old children were superior to the 4-year-old children in both agility tests. The children who played video games well showed higher values in simple reaction time than the children who did not play video games, but not in the repeated sideways jumps. The children who like whole-body dynamic play scored higher than the children who like static play, not only in simple reaction time, but also in the repeated sideways jump test. Although video games affect reaction time of the upper limbs withrespect to visual information, there is no effect on agility for the rest of the body. Enforcing exercise and play time activities, however, would be an effective way to improve the agility of the whole body, in addition to the reaction time of the upper limbs.

[Objective] The Objective of this study was to clarify the relationships among physical fitness, academic achievements, psychological stress scale scores and lifestyles (eating breakfast, sleeping time, time spent for watching television and game). It was done for the subjects of 175 junior high school students in 2014.[Methods] We used the following statistical analyses:the Pearson product-moment correlation coefficient, the one-way analysis of variance, the Bonferroni's method for performing multiple comparisons, the chi-square test by cross tabulation and the logistic regression analysis.[Results] the primary results were as indicated below.1) Academic achievements of boys with higher physical fitness were a little high, and their stress degree was low. They could also perform well on different physical activities such as sit up and standing jump.2) Academic achievements of those who have breakfast everyday were also high, and the stress degree was low. The stress degree of those whose sleeping time a day is less than 6 hours was relatively high.3) According to the logistic regression analysis, among the factors that influenced academic achievements, physical fitness and breakfast showed large influences.As a result, it seems that it is preferable to develop the class of the health education and physical education that considers the physical strength improvement and the breakfast intake.

A survey was conducted to assess physical activity, depression, and sense of coherence among early adolescents. This study used a cross-sectional sample of 12,086 students (G5-G9) from 28 public elementary schools and 22 public junior-high-schools in Japan. A total of 9,424 students (G5-G8) were surveyed from December 2013 to December 2015 using the International Physical Activity Questionnaire (IPAQ) -short form to measure physical activity (PA), the Depression Self-Rating Scale for Children (DSRSC) for depressive symptoms, and the Sense of Coherence Scale-13-item version (SOC-13). Vigorous PA (VPA) of the G5 boys (4h 20 min) was significantly longer than that of the G5 girls (1h 30min) and the VPA of the junior-high-school students increased significantly compared with that of the elementary-school students. The VPA of the G8 boys reached 6h 30 min, whereas that of the G8 girls approached 3h, which was a significant difference. Additionally, more junior-high-school students participated in sports-club activities than did elementary-school students. The mean DSRS-C score of the G5 girls (10.24±5.73) was significantly higher than that of the G5 boys (9.31±5.31). No other differences by grade, were found among the elementary-school students. The depressive symptoms of the junior-high-school students indicated they had a greater risk for depression than the elementary-school students did. The mean SOC score of the G8 boys (44.58±8.11) was higher (better) than that of the G8 girls (43.46±8.30). Furthermore, the elementary-school students' score on the SOC was higher than that of the juniorhigh-school students; the score tended to decrease as the grade increased.

<p>Cross-sectional evidence supports for school connectedness as an important element of healthy youth development. Prospective studies are needed to argue its causal relationship. The aim of this study was to examine whether school connectedness is a determinant of WHO physical activity recommendation for youth in a sample of Japanese junior high school students.</p><p>Analyses were based on one-year with two time-point data of 505 students (265 boys) who entered in five junior high schools in one Okinawan educational office in 2015. School connectedness was evaluated using the sum of a scale constructed from three items "I like school", "School is a nice place to be", and "Sense of belonging at school". Self-reported physical activity was assessed using the Patient-Centred Assessment and Counselling for Exercise plus Nutrition questionnaire.</p><p>According to the analysis by the Generalized Estimating Equation models adjusted for BMI, academic achievement, family structure, and parental education level, the changes in school connectedness score within-person and the differences in average of school connectedness score two-time points between-person were associated with physical activity. Totally, no sex differences in these relationships were found.</p><p>Establishing school connectedness can contribute to the compliance with WHO physical activity recommendation in Japanese junior high school students, regardless of the interindividual differences of level of connectedness to school. Although further research is required to identify the effects of school connectedness on other health-related behaviors, increasing school connectedness should be a consideration for school administrators and health-promotion policymakers.</p>
