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.

近年, スポーツサイエンス領域に臨床検査は重要な役割を果たしている。特に, 競技スポーツは高度化が進み, より高い科学性に基づいたコーチングやトレーニングが不可欠になり, 臨床検査データが受け入れられるようになった。また, 測定機器の簡便化・廉価化, 測定方法の低・非侵襲化により, 臨床検査データをより身近に使用できるようになったことも, 臨床検査の進歩の結果といえる。さらに, ドーピングコントロールにおける検査技術の進歩は, 不正行為の検出に多大な貢献をした。しかしながら, 巧妙化するドーピングは臨床検査の研究者の協力なくしてはありえない。今後, さらに臨床検査のスポーツへの関わりは増えるものと思われる。医の倫理のみならず, スポーツ倫理の教育・啓蒙も重要視しなくてはならない。

The purpose of the present investigation was to examine the relationships between the exercise history and the bone mineral density (BMD) and bone mineral content (BMC) in female Japanese young adults using dual X-ray absorptiometry (DXA). One-hundred twenty females, aged between 18 to 28 years, participated in the present investigation. The BMD at the lumbar spine (L-BMD), whole body BMD and BMC (WB-BMD and WB-BMC), lean body mass (LBM) and fat mass (FM) were measured by DXA. Using a self-administrered questionnaire, the exercise habits during preschool (4-6 years), primary school (7-12 years), junior high school (13-15 years), high school (16-18 years), and the current habits (>18 years) were eveluated. The L-BMD, WB-BMD and WB-BMC were significantly higher in the subjects with exercise habits during both the period of <18 years and >18 years compared with those in the subjects without an exercise history during all periods (p<0.05). In a separate analysis with the data stratified by the school age, the subjects with an exercise history during primary school, junior high school, or high school had significantly higher BMD and BMC values compared with the non-exercisers (each, p<0.05). In contrast, the BMD and BMC did not differ significantly according to either the exercise history during pre-school nor the current exercise status. A multiple stepwise regression analysis revealed that the body weight, LBM, FM, age of menarche, and exercise habits during high school were significant determinants of the L-BMD, WB-BMD and WB-BMC (p<0.001). The results of the present investigation show that both the exercise history during school age and the current exercise habits affect the BMD and BMC in young adults. In particular, high school females should be encouraged to participate in the regular exercise to increase their bone health. Future studies will be needed to confirm the targeted age-group(s) for participation in sports/exercise for the improvement of bone health, including an analysis of the type and intensity of exercise/sports.

本研究の目的は,幼児から中学生の子どもを対象にライフスタイル改善教育及び体力向上プログラムを幼児・学教教育に適用し,同一集団の子どもをそれぞれ縦断的に追跡しながら,その有効性を検証することであった.おもな成果は次の3点であった.1)体力向上プログラムに参加した幼児の体力は,小学校1年で極めて高く,体力A評価は50%を超え,持ち越し効果が確認された.2) 低学年児童を対象に基本的動作習得を目指した8時間の授業で,動作の改善と共に,50m走後半の疾走スピードに有意な改善が見られた.3) 中学校での3年間継続した体力向上への取り組みによって,生徒の遅刻回数や不定愁訴が有意に減少した.

本研究では,若年長距離陸上選手を対象とし乾式遠赤外線低温サウナ浴を用い,陸上競技大会からの筋肉痛回復を検討した.対象者はよく鍛えられた男子陸上選手4名であった.大会後,サウナ浴群(n=2,20.0±1.4歳)またはシャワー浴群(n=2,20.0±0.0歳)は,大会直後(0時間後),そして24,48,72,96,124時間後の計6回,指定されたどちらかの入浴を行った.期間中の測定項目は,身体計測値,採血,MVC,VAS,POMSであった.その結果,高感度C-反応性蛋白(CRP),アルドラーゼ(ALD)が,サウナ群において低値を示す傾向であった.サウナ群において,急性の炎症マーカーが良好な傾向を示したことから,サウナ浴において炎症が抑えられたといえるのかもしれない.This pilot study aimed to examine the effects of far-infrared radiation low temperature sauna bathing on recovery from muscle damage following the race among long-distance runners. The subjects were 4 well-trained male runners. After the running race, the subjects were allocated either the sauna bath group (n=2, aged 20.0±1.4 years) or the shower bath group (n=2, aged 20.0±0.0 years) and bathed 6 times (right after the race, 24, 48, 72, 96 and 120 hours later). The measurements were anthropometrics, blood sampling, maximal voluntary contraction (MVC), visual analogue scale (VAS) concerning muscle soreness and profile of mood states (POMS). In the sauna bath group, C-reactive protein (CRP) and aldolase (ALD) levels tended to be lower compared to the shower bath group. Better results of acute inflammatory markers in the sauna bath group may explain the sauna bathing can suppress the inflammation.
