PURPOSEnThe purpose of this study was to examine whether each exercise and an entire karate training session can achieve: 1) accepted training intensity thresholds for effective aerobic capacity training, 2) energy expenditure (EE) thresholds for total body mass and fat weight loss, and 3) elevation in excess postexercise oxygen consumption (EPOC).nnnMETHODSnWe investigated physiological responses during five types of karate training: basic techniques without (S-Basics) and with (M-Basics) movements, sparring techniques without (TECH I) and with (TECH II) an opponent, and kata.nnnRESULTSnThe mean percent of maximal oxygen uptake (%VO2max) and HR (%HRmax) for S-Basics were below the accepted threshold (60% of HRmax or 50% of VO2max) and for M-Basics, TECH I and TECH II were above the threshold for increasing VO2max. For kata and the entire 70 min of karate training, the mean %HRmax were slightly above the threshold, and %VO2max were slightly below the threshold. The mean EPOC measured for 5 min immediately following 70 min of karate training did not differ from the resting VO2. The mean EE resulting from 70 min of karate exercise and EPOC were 2355.4+/-316.3 kJ and 38.8+/-32.7 kJ, respectively.nnnCONCLUSIONSnAlthough the training intensity of karate exercises studied was moderate and the effects of karate training on EPOC were minimal, the mean value of EE was well above the accepted threshold for total body mass and fat weight loss.

女子学生37名を対象として, 橈骨骨密度に関する諸因子について血中性ホルモンを含めて検討したところ, 橈骨骨密度は身長, 体重, ウエスト囲, ヒップ囲, 体脂肪率, 除脂肪体重, 握力, 中学時代の運動歴と有意な正の相関を示した。また, 身長, 体重, ウエスト, 体脂肪率, 除脂肪体重, 握力の最も高い群が, 低いあるいは中程度の群より橈骨骨密度が有意に高く, 本研究の被検者の橈骨骨密度は, 血中性ホルモンやカルシウム摂取量よりも, 握力や中学校時代の身体活動および体格の影響を受けていることが示唆された。

1日の平均歩数が中高年女性の末梢循環機能に及ぼす影響について検討することを目的として行った。対象は, 平成5~7年に肥満予防教室や糖尿病予防教室等を受講した中高年女性58名であった。受講中の1日の平均歩数が8, 000歩以上であった者をA群 (61.7±6.1歳) , 7, 000歩代であった者をB群 (60.8±6.0歳) , 7, 000歩未満であった者をC群 (65.1±2.5歳) とし, 教室前後で比較を行った。末梢循環機能の評価は, 加速度脈波計を用いて右手第2指の指尖部にて測定した。得られた波形をA~Gに分類, また算出された加速度脈波形数 (APG-Index) を採用した。その結果, すべての群において教室前後で体重, BMIの低下がみられた。A群ではHDLCの増加とFBSの低下がみられ, B群では最大酸素摂取量の増加とSBP, TC, LDL-Cの低下がみられた。A・B群では, 教室後に加速度脈波の波形タイプの改善がみられ, さらに加速度脈波形数の増加もみられた。以上の結果から, 1日7, 000歩, またはそれ以上の歩行により, 中高年女性における末梢循環機能の改善が可能であることが示唆された。
