The posture of school children was studied to find the method to correct their poor postures. The development of the back muscles which are related to the posture maintenance and the equilibrium was also examined.Moiré-topography method was used for measurement. Subjects were 537 boys and girls at 2nd to 6th grade of elementary school and the their full-length bach figures were photogrphed.The following results were obtained.1. Those who had an abnormal posture were 239 pupils, 44.5% of the whole. Those who had a normal one were 298, 55.5%.2. As for the reform training, the following exercise proved to be effective. The child whose right side waist is higher than the left should turn the face rightward, wherever practicable, carry the bag in the right hand, and stand on an inclined plane as the right side on the inclined side. The child whose left waist is higher than the right should do the reverse movements.3. Most of the child who had good posture could stand on one leg with eyes closed for longer time, and balanced themselves on the forward side of their legs when they stood correct. Their good poise had no relation to the development of the back muscles.

The purpose of this study was to investigate the standardization of height growth curves of 8 ethnic groups in Thailand and Union of Myanmar. The height of 16,000 children from 5 to 18 years old of 8 ethnic groups, i. e., Thai, Karen, Hmong, Lisu, Akha, and Lahu in Thailand, Burmese and Mon in Myanmar, was measured from 1994 to 2004 in Thailand, from 2005 to 2008 in the Myanmar. Modified BTT model was applied to height growth curve, and the fluctuation of standard deviation was smoothed using weighted moving variation and smoothing function developed by the authors. Finally growth charts were obtained using z-score of normal distribution. Resultant growth charts were generally satisfactory and were seemed to be useful from the perspective of data utilization. Though there are a few problems on the growth charts such as variance was decreased for more than 15 years old, or height growth has continued till 18 years old in some ethnic groups. Representing heights were different more than 10 cm among ethnic groups at 18 years of age. It was confirmed that it is important to create a growth chart by ethnic group respectively and utilize it in order to evaluate properly the growth status and the nutritional condition of the children.

In Japan previous data did not consider distinguishing between infants' creeping, hands and knees crawling and hands and feet crawling. Therefore the process of these motor skills has not been clearly understood in the national literature and it is incomparable with well-defined international data. In 2015 a detailed questionnaire survey of 307 infants in three prefectures (Hyogo, Okayama and Tottori) revealed that the majority of infants (76.1%) did both creeping and hands and knees crawling. The length of crawling was most frequent between 3 and 4 months, which is a similar figure compared to international research findings. The results further included the measure of shuffling, which is an irregular way of crawling on the back. Substantially 14.7% infants did not process with hands and knees crawling. 11.1% of the group skipped the complete acquisition process and progressed to walking without doing either creeping or any types of crawling.

This study investigated the differences in physical characteristics of Nepalʼs major castes and ethnic groups to create more appropriate standard values with which to evaluate the growth and development of Nepalese children. Data was collected to determine the unique physical characteristics for each group, and this data was further analyzed to combine groups into clusters. Six body measurements (height, weight, chest circumference, sitting height, biacromion breadth, skinfold thickness) were taken of 1,344 children, ages 2-6, from 6 castes and 1 ethnic group in the Sunsari and Sankhuwasava districts of Nepal. Analysis of this data showed growth and physical attributes characteristic for each group. Cluster analysis (Wardʼs Method) was then used to determine similarities between the groups, which resulted in three clusters:high and middle caste cluster (Brahman, Chhetri, Yadav and Koiri), a low caste cluster (Kami and Mushar), and a Sherpa ethnic group cluster. These results indicate that standard values established for each of these clusters will be needed to more accurately evaluate the physical growth of Nepalese children. Because of the distinct physical growth characteristics of each cluster, Nepalese children cannot be properly evaluated using a single standard value for all groups.

This study investigated the effects of a coordination exercise program on quantitative and qualitative changes of throwing and catching ability with the subjects of 5 and 6-year-old 30 preschool children. A4-week control period and a 4-week exercise period were separately set. The exercise program was conducted for 40 minutes a day following the instruction guidance, during 8 days over 4 weeks. The subjects performed motion capacity tests (standing broad jump, side jump) and ball handling tests (control, catching,tennis ball handling) in each period. We evaluated the throwing and catching motions by using five typical developmental stages of motion patterns. As the results, we found a statistically significant increase in the side jump, catching, tennis ball handling and score evaluation for throwing and catching motions in the exercise period compared to the control period. The same results were obtained in both genders. These results suggested that, the coordination exercise program focused on basic ball handling technique may be beneficial to enhance the agility and ball handling capacity in preschool boys and girls aged 5-6, who need an adequate exercise instruction to improve their throwing and catching motions.

The purpose of this study was to make clear the relationship between sleeping habits and sleeping problems and/or physical discomforts among junior high school students. The subjects were comprised of 146 boys and 170 girls in three public junior high schools. The investigation was carried out by a questionnaire in September 2003. The questionnaire contained questions about the time subjects go to bed, time subjects wake up, sleeping problems and physical discomfort. The main findings were as follows: 1) The time subjects go to bed becomes later with increasing age among both boys and girls (p<0.05). Meanwhile, the fluctuations in time to bed showed no significant differences according to sex or grade. 2) The group who went to bed late had significantly higher values for sleeping problem scores and physical discomfort scores (p<0.05). 3) The sleeping problem scores according to fluctuations in time to bed were: for the low fluctuations group, 12.5±13.7 points, 18.7±17.2 points for the middle fluctuations group, and 24.3±20.5 points for the high fluctuations group. The sleeping problem scores for the high fluctuations group were significantly higher than it was for the low fluctuations group (p<0.05). 4) The physical discomfort scores were 20.1±29.8 points for the low fluctuations group, 29.5±30.3 points for the middle fluctuations group and 41.3±30.2 points for the high fluctuations group. The physical discomfort scores for the high fluctuations group were significantly higher than those for the low and middle groups (p<0.05).From the above, it was shown that there is a need for the regulation of time to bed to be added to traditional health education.

The purpose of this study was to examine the effects of a change in life habits on a change in physical fitness in Japanese children using 3-year longitudinal data. The participants were 456 Japanese children aged 6-9 (230 boys, and 226 girls). Data were collected on 3 occasions over a one year period. Survey items included life habits (exercise habits, eating habit, sleeping habit, and TV/video game viewing habit), physical fitness (Japan Fitness Test : Grip Strength, Sit-ups, Sit & Reach, Side Steps, 20 m Shuttle Running, 50 m Dash, Standing Long Jump, and Handball Throwing). Physical fitness in participants was graded into five categories (A-E) according to norm-referenced criteria. Participants of lower two categories (D and E) of physical fitness level was defined as a lower level group. A latent growth modeling was used to examine the influence of the change in a life habit score to a change in a physical fitness score. With the physical fitness change factor, there were statistically significant and positive direct effects from the change in eating habits (slope) only in the lower level group. There were also significant effects from the initial levels of the eating habits, the exercise habits in the all data, and all life habits except for TV/video game viewing habit in the lower level group. These findings, with limited samples and a statistical method, might suggest that an improvement of eating habits has an effect on improvement of physical fitness in a lower level group of physical fitness, and initial levels of life habits also affects improvement of physical fitness.

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.

[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.

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.
