BACKGROUND: Physical activity is beneficial for adolescent health. The physical activity patterns of Japanese adolescents are relatively unknown. Therefore, this study aimed to describe the current patterns of physical activity and to identify sex and grade differences among them. METHODS: The participants comprised 714 Japanese adolescents aged 12 to 15 years old (boys N = 372, girls N = 342) from a public junior high school in Okayama, Japan. Physical activity at school, outside of school after hours, and during lunch recess as well as the total leisure time in a usual week was assessed with a 5-item questionnaire. To assess the differences in the physical activity patterns by sex and grade, independent t tests and analysis of variance (ANOVA) were conducted, respectively. RESULTS: Boys spent significantly more time in physical activity both inside and outside of school settings than girls (p < .05). Higher grade students were significantly less active than lower grade students (p < .05). Furthermore, the physical activity patterns across the grades differed between settings (at school, outside of school during the after-school period, lunchtime recess, and at home). CONCLUSION: To increase physical activity levels among Japanese adolescents, implementation of after-school programs or environmental modifications developed within the school setting could be effective strategies.

子どもの身体活動および座位活動がメンタルヘルスに及ぼす影響について検討した。幼稚園、小学校、中学校を対象としたコホート研究におけるデータの一部を解析した。2010年度初回調査と2012年度調査のデータを使用した。身体活動および座位活動の実施は、2年後のメンタルヘルスや身体活動および座位活動にも関連があることが示された。現在の身体活動および座位活動は、現在のメンタルヘルスのみならず2年後のメンタルヘルスと相関関係を認めた。男子においては、現在の身体活動時間が長いと現在および2年後のメンタルヘルスが良好であることが示された。女子では現在の身体活動時間が長いと現在および2年後の自己効力感は良好であるが、行動は良好ではないことが示された。また、現在の座位活動時間が長いことは女子の2年後の不安傾向および行動、また現在の行動が、男子においては、2年後の自己効力感が良好ではないことが示された。

In this study we examined the association between longitudinal changes in schoolchildren＇sphysical 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 abaseline the students＇ results on the Ministry of Education, Culture, Sports, Science andTechnology＇s new physical strength test, we extracted data on those students whose physicalstrength relatively improved (improved group: 28 boys, 53 girls) and on those whose strengthrelatively declined (declined group: 15 boys, 16 girls). Build, health habits, and psychophysicalhealth index scores were compared between the two groups. It was found that, although therewere 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 orunderweight, have short durations of intense exercise and total exercise, and longer duration ofwatching television or videos. The declined group also showed poorer psychological healthstatus, such as lower self-efficacy and higher anxiety. These findings indicate that children with good exercise habits, such as consistentlyengaging in a adequate physical activities that include intense exercise, will have improvedphysical strength outcome over time, whereas those children with few regular exercise habitsand whose strength will not improve over time, will show outcomes such as polarization ofbody weight (obesity and underweight tendencies) and poorer psychological health status.

The purpose of this study was to assess daily physical activity and time spent on activities of various intensities, and to examine the relationship between daily physical activity and physical fitness in junior high school students. The subjects were 314 junior high school students (135 boys, 179 girls, 14.0 +/- 0.1 years). Daily physical activity was evaluated using accelerometers that they wore around the waist for 10 days. The accelerometers calculated steps and time spent on activities of vigorous intensity (LC7-9: higher intensity than brisk walking). A physical fitness test (8 items) was employed to evaluate the fitness of pupils. The total accelerometer steps (counts/day) were 13772 +/- 4764 for boys and 11209 +/- 2636 for girls on weekdays, and 8311 +/- 4743 for boys and 7159 +/- 3338 for girls on weekends, respectively. On weekdays, time spent on activities with an intensity of LC7-9 (minutes/day) was 18 +/- 17 for boys and 11 +/- 7 for girls. Positive associations were found between physical fitness and daily physical activities in the case of many items. The fitness test score was significantly more highly correlated with LC7-9 than with LC1-6 in boys and girls. In the case of eighth graders, in order to reach a score of B in the physical fitness test, it was suggested that the total steps and time spent on activities with an intensity of LC7-9 may be needed at least 13000 steps and 20 minutes in boys, and 10000 steps and 10 minutes in girls, respectively.

The purpose of present study was to examine validity of pedometer with accelerometer (Lifecorder-EX; LC) and to assess the daily physical activity (PA) of Japanese junior high school Students by LC method. Firstly, to examine validity of LC, ten students (13.6 +/- 0.5 years old),wearing LC on their waists performed the walking and running tests. Energy expenditure was measured by the expired gas analysis method during the tests. The results showed that the activity level of LC had a high correlation with the exercise intensity ((V) over dot O(2): r=0.948, MET's : r=0.931), and it was from 7 to 9 (LC7-9) in the more intense activity than running. Secondly, PA of 206 boys and 220 girls aged 12-15 years were measured using I-C. Step Counts and activity time of LC7-9 each were 9500-15000 Counts and 10-19 minutes on weekdays, and 6500-10000 counts and 5-12 minutes on weekends. PA analyzed by MANOVA were lower on weekends than oil weekdays, and decreased in proportion as grade. and that of boys were significantly higher than that of girls. Present study suggests that LC method is a good way of measuring PA for junior school students in free-living condition. (Jpn. J. Phys. Fitness Sports Med. 2009, 58 : 275 similar to 284)

The purpose of this Study Was to assess daily physical activity and time spent, on activities of various intensities, and to examine the relationship between daily physical activity and physical fitness in elementary school children. Subjects were 288 elementary school children (140 boys, 148 girls, 9.6 +/- 0.5 years). Daily physical activity was evaluated by accelerometers, worn around the waist for 10 days. Accelerometers calculated steps and vigorous intensity time (LC7-9: higher intensity than brisk walking). A physical fitness test (8 items) was applied to evaluate fitness in pupils. Total accelerometer steps (counts/day) were 18333 +/- 3869 for boys and 13957 +/- 2970 for girls oil weekdays, and 11932 +/- 4827 for boys and 9767 +/- 4542 for girls on weekends. respectively. Time spent in LC7-9 (minutes/day) was 31 +/- 12 for boys and 20 +/- 7 for girls on weekdays. Positive associations were found between physical fitness and daily physical activities for manY items. Above all, there was a relatively strong correlation between aerobic capacity and LC7-9 time. On the other hand, the correlations were low among girls. For fourth graders, in order to reach a B rank score in the physical fitness test, it was suggested that the total steps and LC7-9 time required at least 17000 steps, 30 minutes in boys, and 13000 steps, 20 minutes in girls, respectively.

This study aims to examine children's physical activity with accelerometer by evaluating daily steps and activity time of walking and running classified by accelerometer's intensity, and to create basic data for standard values of appropriate children's daily activity.<br>The result showed that the means of daily step counts (steps day) are 10, 000-15, 000. The activity time of walking (recorded as 1-6) is 90-120 minutes/day, and above running (recorded as 7-9) is 15-27 minutes/day. MANOVA analysis of physical activity parameter show significant between boys and girls (walk counts: F=7.27, p<0.01, LC1-6: F=9.37, p<0.01), weekday and weekend (walk counts: F=146.39, p<0.0001, LC1-6: F=107.71, p<0.0001, LC7-9: F=158.23, p<0.0001).<br>But it did not show significant difference between ages. Overall, it is shown that activity volume and intensity are smaller for girls than for boys, and on holidays than weekdays. The interaction was not significant between every combination.
