| 摘 要： | 目的:应用运动传感器SWA测量青少年日常体力活动的能量消耗,了解青少年日常体力活动状况,探讨SWA在体力活动测量中的应用价值.方法:随机抽取上海市30名中学生作为调查对象,男女各半.受试者佩带SWA,固定于优势侧上臂肱三头肌处,每天早晨起床后戴上,一直到晚上睡觉前摘下,连续佩戴7 d,记录体力活动的能量消耗和活动时间.结果:男生1周总能量消耗和平均每天进行的中等强度、大强度体力活动能量消耗和时间高于女生(P<0.01);在平均每天的能量消耗构成比中,男生从事大强度的体力活动能耗为10%,中等强度的能耗为14%,女生从事大强度的体力活动能耗为4%,中等强度的能耗为12%.个体间体力活动能耗为10.44%-46.03%.结论:目前青少年的体力活动水平参差不齐,存在着明显的性别差异,并且随着年龄的增长,体力活动水平下降.SWA具有较好的客观性、可靠性和实用性.
