kn-abstract=　In this study, data from a survey completed before the spread of COVID-19 were used to measure the amount of physical activity in school among eighth graders attending special-needs schools and compared with the WHO Guidelines for Physical Activity and Sedentary Behavior. The subjects were 16 eighth graders in public special-needs schools. In addition to height and weight, the physical activity survey during school life was measured using a uniaxial accelerometer (Kenz Lifecorder GS 4-second version: LC). 7534 ± 2275 steps/day for boys, 6411 ± 1614 steps/day for girls, and middle and high intensity activity time (MVPA) was 19.3 ± 10.3 minutes/day for boys and 16.7 ± 8.3 minutes/day for girls. These results suggest that eighth graders attending special needs schools are well below the WHO Guidelines for Physical Activity and Sedentary Behavior standard of 60 minutes/day for children and adolescents with disabilities (5-17 years old ) for both boys and girls.

kn-title=Longitudinal changes and tracking of in-school physical activity in primary school children: four-year longitudinal study
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=Background There is little evidence on the tracking of physical activity during school hours. In addition, tracking physical activity in schools provides important evidence for understanding children’s physical activity and conducting intervention studies. Therefore, this study examined longitudinal changes and tracking of in-school physical activity in primary school children.<br>
Methods In this study, physical activity was investigated longitudinally in primary school children for 4 years. The baseline participants consisted of 103 second-grade students (7–8 years old) who participated. Step counts and moderate-to-vigorous physical activity (MVPA) in school and during first recess and lunch/second recess were examined using an accelerometer (Kenz Lifecorder GS 4-second version; Suzuken Co. Ltd, Nagoya, Japan).<br>
Results After excluding missing data (moving school; n = 8, physical activity; n = 8), 87 (43 boys and 44 girls) of whom were included in the final analysis. Step counts and MVPA during school and physical education in boys did not decrease across the school years. By contrast, in girls, step counts during school did not decrease across the school years, however MVPA did decrease. In addition, for both sexes, step counts and MVPA during first recess decrease across the school years. During lunch/second recess, only step counts decrease across the school years in both sexes. In addition, the tracking coefficients for step counts and MVPA for boys in school and during first recess and lunch/second recess were found across many school years. Contrarily, girls had fewer significant tracking coefficients between school years than boys. There were also few significant tracking coefficients between grades for physical education step counts and MVPA for both boys and girls.<br>
Conclusions Our results suggested that in-school step counts for both boys and girls does not decrease across the school years. However, given that girls demonstrated reduced levels of in-school MVPA across the school years, it is important to promote strategies to increase MVPA in this group.

kn-abstract=　本稿の目的は，体育科の教科内容構成の固有性とは何か，という問いに対する回答を提示し，体育科の教科内容構成における基本的な教材研究及び教材開発の方法論を示していくことである。そのために，まず体育科の内容・指導の４つの特殊性を概観した上で，各特殊性について検討し，教科内容構成の他教科に対する固有性を構造的に捉えた。　議論の結果，体育科における教科内容構成は，以下の固有性を有していることが明らかになった。①運動内容と学習内容を別に認識する必要がある，②からだとこころの一体化と解放を中核的な認識原理として持っている必要がある，③子どもの心身の発達が，学習方法・指導方法だけでなく，運動内容・学習内容も決定づける，④教科内容構成に際して，スポーツ科学諸領域の知見が必要になる。

en-subtitle=

kn-abstract=In this study we examined the association between longitudinal changes in schoolchildren＇s
physical strength with their build, health habits, and psychophysical health index scores.
Students (n= 195) were followed for three years, from the fifth to the eighth grade. Setting as a
baseline the students＇ results on the Ministry of Education, Culture, Sports, Science and
Technology＇s new physical strength test, we extracted data on those students whose physical
strength relatively improved (improved group: 28 boys, 53 girls) and on those whose strength
relatively declined (declined group: 15 boys, 16 girls). Build, health habits, and psychophysical
health index scores were compared between the two groups. It was found that, although there
were no significant differences in eating habits or sleeping habits between the two groups,
compared to the improved group, the declined group was more likely to be either obese or
underweight, have short durations of intense exercise and total exercise, and longer duration of
watching television or videos. The declined group also showed poorer psychological health
status, such as lower self-efficacy and higher anxiety.
　These findings indicate that children with good exercise habits, such as consistently
engaging in a adequate physical activities that include intense exercise, will have improved
physical strength outcome over time, whereas those children with few regular exercise habits
and whose strength will not improve over time, will show outcomes such as polarization of
body weight (obesity and underweight tendencies) and poorer psychological health status.

kn-abstract=The purpose of this study was to clarify physical fitness(PF) characteristics of obese and lean adolescent classified by combining somatotype, and body composition. Somatotype were measured by obesity index from weight and height measurement. Body composition given as percentage body fat was calculated by measuring skinfold thickness. The measurement of PF consisted of 12 tests. In addition, comparison were made in each somatotype group between the high percentage body fat group and the normal group. PF were lower in overweight or underweight group than in normalweight group. At overweight and normalweight groups, the high percentage body fat group attained scored lower in most PF test items. However, at underweight group, normal percentage body fat group attained scored lower in 6-7 items.
