一般の高齢者の運動習慣の実態を明らかにし,運動習慣と体力との関連について検討することを目的に,都市在住の60〜89歳の高齢者179名(男子82名,女子97名)を対象に,体力診断バッテリーテストの実施とともにあわせて運動習慣の調査を行い,以下の結果を得た.A.体力診断テストは,全ての項目で年齢と負の相関関係が認められた.B.何らかの運動習慣がある者は,男子87.8%,女子88.5%であったが,その内容は,散歩が最も多く,以下植木いじり,ゲートボール,ラジオ体操およびその他の体操,ハイキングの順であった.C.運動習慣のある者の体力診断バッテリーテストの成績は,無い者に比べ優れた値を示し男子では握力,息こらえ,総合点で,女子では握力を除く全項目で両群間の差が有意であった.D.運動の頻度,時間による各運動条件群間での体力の平均値は,両者とも多い者が少ない者より優れた傾向を示したが,その差は運動習慣のある者の間では比較的小さいものであった.E.はや足程度(RMR3.5)以上の運動を実施している者は,運動習慣の無い者やそれ以下の強度の運動実施者より優れた体力を示した.F.家事等で歩くエネルギーを加えた運動のエネルギー需要量(安静時代謝量を含まない)が多い者ほど体力診断テストの成績が優れていた.本調査では,運動の種類や実施状況によって体力差が認められた.しかし,最も大きな差は,現在,運動習慣があるか無いかにあったことより,高齢者においては体力の低下を防ぐ(あるいは低下を遅らす)ためには,比較的低レベルの身体運動でも有効であることが示唆された.

The present study was aimed to survey the relation between habitual exercise and the quality of nocturnal sleep. Questionnaires on exercise behavior and sleep were given to 452 male and female unuversity students. The questionnaires included such questions as; on their habitual exercise the kind of exercise, duration and frequency of doing the exercise, the period of continuation, rating of perceived exertion (RPE) and subjective feeling of their exercise load for health (heavy, suitable, light). TMIN Life Habits Inventory were conducted to ascertain the quality of sleep. The results of all the students showed that they were more likely to experience insufficient asleep period (64.6%), were not refreshed in the morning (40.0%), found unbearable daytime napping (38.5%). The student group with habitual exercise (n=237) showed significant "more easily fall asleep" (p<0.05) and" more insufficient asleep period" (p<0.05) tendencies than the group without habitual exercise. Further, three groups divided by their subjective feeling toward their exercise load showed some significantly different quality of sleep. The students who felt that their habitual exercise was "suitable" or "light" showed better sleep, with reference to frequency of naid-sleep awakening and deepness of sleep, as compared with students who felt that their exercise was "heavy" (p<0.05). These results indicate that suitable or light habitual exercise might facilitate better quality of sleep while heavy exercise which strongly activate the sympathetic nervous system, pose a risk to disrupt sleep.

本研究の目的は高酸素気吸入トレーニングが平地での全身持久力に及ぼす効果を明らかにすることであった。日常規則的な持久性のトレーニングを行っていない男子体育学部生12名を被験者とし、正常気吸入トレーニング群(正常気群)および高酸素気吸入トレーニング群(高酸素気群)に2分した。高酸素気群のトレーニング強度は高酸素(60%酸素)吸入時に得られたV^^・o_2maxの85%、正常気トレーニング群の強度は空気吸入時に得られたV^^・o_2maxの85%とした。トレーニング時間は高酸素気群を10分とし、両群の仕事量を等しくするために、正常気群は10分22秒から11分30秒とした。また、トレーニングの頻度および期間は両群とも週3日および4週間であった。この結果、正常気群ではオールアウトタイムが17分18秒±1分37秒から19分7秒±1分53秒および乳酸閾値が19.6±4.3ml/kg・分から23.0±4.5ml/kg・分にそれぞれ有意に向上した。V^^・o_2max、最大換気量およびトレーニング中の心拍数には変化は認められなかった。一方、高酸素気群ではオールアウトタイムが17分56秒±1分24秒から19分33秒±1分41秒および乳酸閾値が19.7±3.0ml/kg・分から24.9±4.0ml/kg・分に有意な向上を示したことに加え、V^^・o_2maxお 46.14.6ml/kg51.04.3ml/kg117.313.8l/135.118.4l/V^^o_2max

Deaths and morbidity due to heat disorders during physical activity were gleaned from newspaper reports between 1970 and 1990. The environmental temperatures (dry-bulb temperature and relative humidity) recorded at the closest meteorological observatory at the time of occunence were used to calculate the wet-bulb temperature and WBGT (wet-bulb globe temperature), and the relationship between heat disorders and environmental temperature was analyzed. During the 21-year period, 108cases of heat disorders (91 deaths and 477 casualties) were reported in newspapers. Of the 91 deaths, 9 were in females and 82 were in males, and meanages were 23.3years, females and 19.0 years, males. It was possible to record the environmental conditions at the time of the heat disorder in 99 cases. The results indicated that almost all disorders occurred at ranges higher than 25.5℃, dry-bulb temperature, and 20.0℃, wet-bulb temperature, 40% relative humidity, and 24.0℃, WBGT. The mean WBGT was 28℃ at physiological intensities less than 12-RMR (Relative Metabolic Rate) and 25.8℃ at RMR higher than 15. The seasonal distribution was from April to November. In cases observed in April, May and November, abrupt rises in WBGT in the 1.2〜3.4℃ range were observed on the day of occurrence in comparison with the previous day, suggesting that the degree of heat acclimatization is olso an important factor in preventing heat disorders.

The subjects were five male race-walkers (race-walker group) and five male college students (control group). The results obtained were as follows : 1.Under race-walk conditions,the highest speeds attained in the race-walker and control groups were 200〜220 m/min and 160m/rnin, respectively. Under normal walking conditions, however, the values were 140 m/nlin in both groups. 2.A lower oxygen requirement was observed at slower speed during normal walking and at a higher speed(over 130 m/min) during race-walking. 3.Oxygen requirement(ml/kg/100 m) in the race-walker group was minimal at 60〜80 m/min during race-walking and at 60 m/min during normal walking.Values in the control group were minimal at 60 m/min under both walking conditions. 4.The oxygen requirement in the race-walker group was less than that of the control group under both walking conditions. 5.Under normal walking conditions,as the speed increased,both step-length and step frequency gradually increased,until step-length reached a limit of 80 cm. Thereafter, walking was maintained only by an increase in step frequency.However,in the race-walkes group,the subjects were capable of increasing their step-length further,and maintaining a higher speed(up to 220m/min). 6.It was suggested that race-walking is one of the most efficient exercises for maintaining and improving health.
