中文摘要:

目的：通过比较肥胖与正常体重男性青年不同站姿下的静态平衡任务测试结果，探讨肥胖与视觉等因素对人体静态平衡能力的影响。方法：招募符合本研究纳入与排除标准的男性青年受试者24名（肥胖组、正常体重组各12名），以随机顺序完成睁眼双腿站立、闭眼双腿站立、睁眼左腿站立、睁眼右腿站立4项静态平衡任务测试，通过Kistler三维测力台采集动力学数据。采用双因素（组别×站姿）重复测量方差分析对各个指标进行统计分析。结果：外周面积组间比较，肥胖组4项静态平衡任务测试中的外周面积均大于普通组（P＜0.05）；组内比较，肥胖组闭眼双腿站立时外周面积大于睁眼双腿站立（P=0.028），而正常体重组两项测试之间无显著性差异（P=0.85）。两组人群闭眼双腿站立测试前后、内外方向最大摆动幅度以及摆动速度大于睁眼双腿站立（P＜0.05）；肥胖组睁眼、闭眼双腿站立以及睁眼非优势腿站立时的压心总摆动幅度大于正常体重组（P＜0.05）。结论：肥胖男性青年优势腿及双腿站立时静态平衡能力均弱于正常体重男性青年；在视觉受限的条件下，尽管两组人群的静态平衡能力均有所减弱，但肥胖人群的平衡能力下降现象更为显著。

英文摘要:

Objective: The objective of this study is to investigate the effects of factors such as obesity and vision on human static balance ability by comparing obese and normal weight male adolescents in different standing postures in a static balance task. Methods: A total of 24 young male subjects (12 in each of the obese and normal weight groups) were recruited to perform four static balance task tests in a randomised order. The tests included eyes open two-legged standing, eyes closed two-legged standing, eyes open left-legged standing, and eyes open right-legged standing. Kinetic data were collected using the Kistler three-dimensional dynamometer table. A two-factor (2 groups× 4 standing positions) repeated measures ANOVA was employed to statistically analyse each index. Results: The peripheral area was greater in the obese group than in the normal group in all four static balance task tests (P＜0.05). Furthermore, the peripheral area was greater in the obese group than in the eyes-closed legs standing test (P=0.028), whereas there was no significant difference in the normal weight group between the two tests (P=0.85). Finally, the maximal swing amplitude in the anterior-posterior and internal-inferior directions as well as the speed of the swing were greater in the eyes-closed legs standing test than in the eyes-open legs standing test (P＜0.05). Moreover, the total swing amplitude of the pressure center was greater in the obese group than in the normal body group for the eyes-open, eyes-closed two-legged standing, and eyes-open nondominant leg standing tests (P＜0.05). Conclusion: The study found that obese young men were weaker than normal-weight young men in static balance on the dominant leg and in two-legged stance. Under visually restricted conditions, while both groups experienced a decrease in static balance ability, the decline was more pronounced among obese individuals.
