摘要
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 reference values of energy expenditure of physical activity for adolescents in Shanghai. Methods Adolescents,aged 11 -16,in Shanghai were recruited in this study. BMI,vital capacity and endurance capacity of the subjects were measured,and physical activity were investigated by questionnaire. Subjects who met the inclusion criteria of normal BMI,vital capacity, endurance capacity ,strength,speed ,and agility were grouped by every two years of age （n = 400 for each group,including 200 males and 200 females）. 95% confidence interval of moderate and vigorous intensity physical activity were established by statistical methods. Back substitution test was performed in each age group （males = 20,females=20） selected randomly from the subjects. Results Reference values of energy expenditure （kcal/w） in moderate-intensity physical activity for boys aged 11-12-, 13- 14-, 15 - 16-year-old were ： 971.19 - 1271.58,1081.16-1492.94, and 1324.56 - 1712.37, respectively; and for girls 1139.82 -1437.37,1046.69-1398.77 and 1113.15 -1427.22,respectively. Reference values of energy expenditure in high-intensity physical activity for boys aged 11-12-, 13-14-, 15-16-year-oldwere ： 1167.75 -1486.57 ,1226.24 -1715.26, and 1117.23 -1453.33, respectively ;and for girls ： 843.53 - 1141.61,676.01 - 1006.54 and 1142.53 - 1392.51, respectively. Back substitution test showed that 75% - 87% of the adolescents were included in the established 95% confidence interval. Conclusion Reference values of energy expenditure for Shanghai adolescents aged 11 -16 during moderate and vigorous intensity physical activity were established in this study.
