目的研究儿童体脂含量与运动素质的关系,为增强学生体质提供依据。方法抽取小学一年级学生300人,测量肱三头肌和肩胛下角部皮脂厚度,推算体脂比。测量身高、体质量、血压、肺活量、50 m跑、立定跳远、立位体前屈5、0 m×8往返跑等形态、机能和素质指标。结果体脂比与身高、体质量、血压、肺活量均呈显著正相关(P<0.01),男生体脂含量与速度、耐力、下肢爆发力、身体柔韧性素质呈显著负相关(P<0.01),女生体脂含量与耐力和身体柔韧性素质呈显著负相关(P<0.05)。结论体脂含量增加对身体素质发展不利。
Objective To study the relationship between body fat content and motor quality in children and to provide basis for enhancing students’ physique. Methods A total of 300 freshmen in primary school were enrolled in this study. The sebum thickness of triceps and subscapular horn was measured. Measurement of height, body mass, blood pressure, vital capacity, 50 m running, standing long jump, standing body flexion 5,0 m × 8 round-trip and other forms, functions and quality indicators. Results There was a significant positive correlation between body fat percentage and body height, body weight, blood pressure and vital capacity (P <0.01). There was a significant negative correlation between body fat content and speed, endurance, explosive force of lower extremity and flexibility of body (P <0.01) There was a significant negative correlation between body fat content and endurance and body flexibility of girls (P <0.05). Conclusion The increase of body fat content is unfavorable to the development of physical fitness.
