生物电阻抗法测量空勤人员人体成分及分析

Study on Human Body Composition Analysis of the Aircrewmen by Bioelectricity Impedance Method

目的:调查空勤人员和地方人员在人体成分上是否存在差异,分析其原因。方法:用人体成分分析仪分别检测空勤人员与地方人员的水分、蛋白质、脂肪和无机盐等成分,并记录日常进行体育锻炼的情况。结果:空勤人员及地方人员的肌肉质量、去脂体质量、蛋白质、水分、无机盐的含量分别为(57.8±4.32)kg、(60.9±4.51)kg、(16.4±1.15)kg、(41.5±3.16)kg、(3.26±0.19)kg及(51.9±5.53)kg、(54.8±5.78)kg、(13.8±1.64)kg、(38.0±4.52)kg、(2.98±0.31)kg,两组人员体成分含量差异具有统计学意义(P<0.05),运动时间分别为(56±3.76)min及(176±4.12)min,运动时间空勤人员大于地方人员(P<0.05)。结论:空勤人员蛋白质、水分和无机盐含量更丰富,肌肉和骨骼更发达,体育锻炼对健康十分重要。

Objective： To investigate the body compositon of aircrewmen and common people, then analyze the differences between the two groups. Method： Body composition was analyzed in 51 aircrewmen and 125 common people, and their physical exercise hours were recorded. Results： The muscle weight, lean body weight, protein content, fluid content, mineral content in aircrewmen group were（57.8±4.32）kg,（60.9±4.51 ）kg,（16.4± 1.15）kg,（41.5±3.16）kg,（3.26±0.19）kg（51.9±5.53）kg,（54.8±5.78）kg,（13.8± 1.64）kg,（38.0±4.52）kg,（2.98±0.31） kg in common people group, and these indexes in aircrewmen group were significiantly higher than in common people group（P〈0.05）.The physical exercise hours were （56±3.76）min and （176±4.12）min espectively, and the index in aircrewmen group was significiantly longer than in common people group（P〈0.05）. Conclusion： The muscles and bones of the aircrewmen were much stronger than common people＇s, and physical exercise can make valuable contributions to our health.
