目的:建立上海市青少年体力活动能量消耗的参考值。方法:以上海市11-16岁青少年为调查对象,进行体质健康项目测试,并进行体力活动问卷调查。在BMI正常、肺活量和耐力、柔韧力量、速度灵巧项目在及格以上的青少年中,按每2岁一个年龄段分组,每组随机选取男女各200人,用统计学方法分别建立中等强度和大强度体力活动能量消耗的95%置信区间;每年龄组再随机选取男女各20人进行回代检验。结果:11-12岁、13-14岁、15-16岁中等强度体力活动能量消耗(kcal/w)95%置信区间分别为:男生971.19-1271.58、1081.16～1492.94、1324.56-1712.37,女生1139.82-1437.37、1046.69-1398.77、1113.15-1427.22;大强度体力活动能量消耗(kcal/w)95%置信区间分别为:男生1167.75-1486.57、1226.24-1715.26、1117.23-1453.33,女生843.53～1141.61、676.01-1006.54、1142.53-1392.51。回代检验时,各年龄组有75%-87%的对象在所建立的95%置信区间内。结论:初步建立了上海市11-16岁青少年中等强度和大强度体力活动能量消耗的参考值。
Objective: To establish the reference value of physical activity energy expenditure of adolescents in Shanghai. Methods: The 11-16-year-old adolescents in Shanghai were selected as the test subjects for physical fitness test and physical activity questionnaire. In the normal BMI, vital capacity and endurance, flexible strength, speed dexterity project in adolescents over the age of two, according to an age group, each group of 200 men and women were randomly selected, using statistical methods to establish moderate and high intensity 95% confidence interval of physical activity energy expenditure; each age group randomly selected 20 men and women for back-substitution test. Results: The 95% confidence intervals of energy expenditure (kcal / w) of 11-12 years old, 13-14 years old and 15-16 years old were as follows: male 971.19-1271.58,1081.16 ~ 1492.94,1324.56-1712.37, female 1139.82- 1437.37,1046.69-1398.77,1113.15-1427.22. The 95% confidence intervals of energy expenditure (kcal / w) for intensive physical activity were 1167.75-1486.57, 1226.24-1715.26, 1117.23-1453.33, 843.53-1141.61, 676.01-1006.54, 1142.53-1392.51. At the time of back-testing, 75% -87% of the subjects in each age group are within the established 95% confidence interval. Conclusion: The reference values of energy expenditure of middle-strength and high-intensity physical activities of 11-16-year-old adolescents in Shanghai are preliminarily established.
