【摘要】：目的通过三轴加速度计对老年人7 d的体力活动监测,分析老年人日常体力活动与能量消耗的状况,为老年人群的体力活动开展、各种老年疾病的运动护理及运动促进健康的科学指导等提供依据。方法选择2015年1~6月在沈阳市第四人民医院进行健康体检的老年人50例。其中男20例、女30例,男、女之间体质量指数(BMI)无显著性差异。征得研究对象同意后,在身体右侧髂前上棘部位佩戴加速度计监测日常体力活动7 d,每天佩戴10 h以上,并确保周一至周五有2 d和周六至周日有1 d的有效数据。加速度计型号为Actigraph GT3X(美国),采样间隔10 s,采集参数为每天平均的佩戴时间、轻体力活动时间、中等强度活动时间、高强度活动时间、总计数值、平均每分钟计数值、步数和平均代谢当量等,数据统计处理由SPSS软件完成。结果老年人的体力活动主要以轻体力活动为主,轻体力活动时间为佩戴时间的86.96%~88.90%,平均代谢当量(METs)介于1.21~1.29之间,均属于轻度体力活动范围。结论老年人日常体力活动存在着明显不足现象,这也是老年人心血管病和其他慢性疾病发生的潜在风险因素,有必要提高老年人的运动防护意识,促进老年人体力活动的开展,适当增加中等强度的有氧运动并给予运动促进健康的科学指导,以降低各种老年疾病的发生。
[Abstract]:Objective to analyze the daily physical activity and energy consumption of the elderly by using triaxial accelerometer to monitor their physical activity for 7 days, so as to carry out physical activities for the elderly.Sports nursing and scientific guidance on health promotion of various senile diseases are provided.Methods A total of 50 elderly patients who underwent physical examination in the fourth people's Hospital of Shenyang City from January to June 2015 were selected.There was no significant difference in body mass index (BMI) between 20 males and 30 females.With the consent of the subjects, the right anterior superior iliac spine was used to monitor daily physical activity for 7 days and more than 10 hours a day, and to ensure that there were 2 days from Monday to Friday and 1 day from Saturday to Sunday.The accelerometer model is Actigraph GT3X (USA, sampling interval 10 s), the acquisition parameters are average daily wear time, light physical activity time, moderate intensity activity time, high intensity activity time, total value, average count value per minute,Step number and average metabolic equivalent were processed by SPSS software.Results the main physical activity of the elderly was light physical activity, the time of light physical activity was 86.96 / 88.90 and the mean metabolic equivalent was between 1.21 and 1.29, which belonged to the range of mild physical activity.Conclusion the physical activity of the elderly is obviously insufficient, which is also the potential risk factor of cardiovascular disease and other chronic diseases in the elderly. It is necessary to improve the awareness of exercise protection and promote the physical activity of the elderly.Appropriate increase of moderate aerobic exercise and scientific guidance of exercise to promote health in order to reduce the incidence of various diseases in the elderly.
