OBJECTIVE
The relationships between physical activity, fitness, and CHD risk factors were investigated in 342 males and 268 females 9-18 years of age.
METHODS
Daily energy expenditure, moderate to vigorous physical activity, inactivity, and television viewing time were estimated. Indicators of physical fitness included submaximal work capacity, quadriceps muscle strength, sit-ups, and the sum of six skinfolds. Risk factors included mean arterial blood pressure and fasting blood levels of triglycerides, LDL-cholesterol, HDL-cholesterol, and glucose.
RESULTS
Canonical correlations between activity and risk factor profiles range from 0.22 to 0.45, while those between fitness and risk factor profiles range from 0.34 to 0.55, indicating that 5 to 20% and 11 to 30% of the variance in the risk profile is explained by activity and fitness, respectively.
CONCLUSION
The results suggest that both physical fitness and level of habitual physical activity are strongly associated with CHD risk factors in this sample of youth.
目的
在342名9至18岁男性和268名9至18岁女性中，研究身体活动、健康状况与冠心病危险因素之间的关系。
方法
估计每日能量消耗、中度至剧烈身体活动、不活动时间和看电视时间。身体健康指标包括次最大工作能力、股四头肌力量、仰卧起坐次数和六个皮褶厚度之和。危险因素包括平均动脉血压以及甘油三酯、低密度脂蛋白胆固醇、高密度脂蛋白胆固醇和血糖的空腹血水平。
结果
活动与危险因素概况之间的典型相关系数在0.22至0.45之间，而健康状况与危险因素概况之间的典型相关系数在0.34至0.55之间，这表明危险因素概况中分别有5%至20%和11%至30%的变异可由活动和健康状况解释。
结论
结果表明，在这个青年样本中，身体健康状况和习惯性身体活动水平均与冠心病危险因素密切相关。
