1. The effects of the sport activity on the aeteriosclerotic risk factors were investigated in 333 junior high school students(176 boys and 157 girls). The body fat ratio(%fat), the systolic blood pressure(SBP), the diastolic blood pressure(DBP), the serum high density lipoprotein cholesterol(HDL-C)and total cholesterol(T-C)levels, and atherosenic index(AI)were evaluated, once a year for three years. The students were divided into inactive groups(24 boys, 32 girls)and active groups(115 boys, 109 girls)from the questionnaires, based 'on the attendance rate at sport practice in some sport club(50%<, 50%<greater than or equal>, respectively). The results were as follows : (1)In the 1st year, there was no significant difference in any risk factor between the inactive and active groups. (2)In the 2nd year, DBP, T-C, AI were significantly lower in the active boy group than in the inactive boy group, and %tat was lower in the active boy group compared with the inactive boy group, though not s … More tatistically significantly. DBP were significantly lower in the active girl group than in the inactive girl group. (3)In the 3rd year, when all students have discontinued the sport activity 3 months before the examination, there was no significant difference in any risk factor between the active and inactive groups. We conclude that the regular exercise may have suppressive effects on the arteriosclerotic risk factors in adolescents, and the continuation of a regular exercise habit is important to prolong the2. The effect of the sport activity on the aortic elasticity was evaluated by measuring the aortic pulse wave velocity(APWY), which is to be increased with increasing the aortic Youngs's modulus, longitudinally in 32 junior high school boy students, who consisted of 22 active boys and 10 inactive boys, once a year for three years. The physical fitness level of the active groups was higher than that of the inactive group in the 2nd and 3rd year. The APWV, however, did not show any difference between the-two groups through the three years. The effect of sport activity on the aortic elasticity might not be obvious in the younger generation, or a longer observation period should be necessary. Less

1.对333名初中生（男176名，女157名）进行了体育锻炼对患病危险因素影响的调查。观察两组患者的体脂率（%fat）、收缩压（SBP）、舒张压（DBP）、血清高密度脂蛋白胆固醇（HDL-C）、总胆固醇（T-C）水平及动脉粥样硬化指数（AI）。根据参加某体育俱乐部体育锻炼的比例（50%、50%），将学生分为不参加体育锻炼组（男生24人，女生32人）和参加体育锻炼组（男生115人，女生109人<greater than or equal>）。结果表明：（1）第1年，非活动组与活动组的各项危险因素均无显著性差异。(2)In第2年，活动组DBP、T-C、AI显著低于非活动组，%达特显著低于非活动组，但活动组与非活动组无显著性差异。 ...更多信息 在统计学上显著。活动组舒张压明显低于非活动组。(3)In第3年，当所有学生在考试前3个月停止体育活动时，活动组与非活动组的任何危险因素均无显著差异。我们的结论是，定期运动可能对青少年动脉粥样硬化危险因素有抑制作用，持续定期运动习惯对延长2。本文通过测量主动脉脉搏波速度（APWY）来评价体育活动对主动脉弹性的影响。APWY随主动脉杨氏模量的增加而增加。第2年和第3年，运动组的身体素质水平高于非运动组。然而，APWV在三年中没有显示出两组之间的任何差异。运动对年轻一代主动脉弹性的影响可能不明显，或需要更长的观察期。少
