摘要:


文题释义:
动态稳度:一种能够综合量化支撑面、质心速度和位置这3个因素对身体稳定性影响的指标。
跨越障碍:受试者自然行走过程中单腿跨越障碍物。
越障:人体越障的过程是失去平衡和恢复平衡的动态过程,质心始终处于动态变化过程中。在跨越障碍前,为防止绊倒,摆动腿会尽可能抬高以跨越障碍,这一过程中质心不断提高,稳定性降低。

背景:肥胖对步行时的动态平衡产生负面影响,而跨越障碍是较为日常的功能活动,对控制身体姿势的稳定性要求更高。
目的:探讨肥胖男性与普通男性动态稳定性的差异,采用相对更具挑战性的跨越障碍对肥胖男性的平衡能力进行评估。
方法:招募24名男性青年,肥胖组与普通组(非肥胖组)各12名,分别以随机顺序完成平地行走和不同高度(4,11,15 cm)障碍物的跨越测试。使用Qualisys运动捕捉系统与Kistler测力台采集运动学与动力学数据。采用双因素(2组别*4动作类型)重复测量方差分析,对各指标进行统计分析。
结果与结论:①肥胖组比普通组步速更低(P < 0.05),跨越11 cm与15 cm障碍时第一单支撑期占比减小,第二双支撑期占比增加(P < 0.05);②在平地行走时,普通组的内外方向动态稳度大于肥胖组(P < 0.05);③在跨越4 cm障碍时,肥胖组前后方向动态稳度低于普通组(P < 0.05);④在跨越11 cm障碍时,两组前后方向动态稳度无显著性差异(P > 0.05),而内外方向差异有显著性意义(P < 0.05);⑤在跨越15 cm障碍时,肥胖组动态稳度低于普通组(P < 0.05);⑥提示肥胖使人体在跨越障碍过程中对身体的控制能力下降,动态稳定性降低,发生跌倒的风险较普通人群更高;此外,相较于平地行走,跨越障碍时肥胖组稳定性下降较普通人群更为显著。

Abstract: BACKGROUND: Obesity negatively affects dynamic balance during walking, and crossing barriers is a more routine functional activity that requires more stability in controlling body posture.
OBJECTIVE: To investigate the differences in dynamic stability between obese and average males, and to assess the balance ability of obese males using a relatively more challenging obstacle crossing.
METHODS: A total of 24 male youths (12 each in the obese and normal groups) were recruited to complete the tests of walking on level ground and crossing obstacles of different heights (4 cm, 11 cm, 15 cm) in random order. Kinematic and dynamic data were collected using the Qualisys motion capture system and Kistler force stage. Statistical analysis was performed using two-factor (2 groups * 4 movement types) repeated measures analysis of variance.
RESULTS AND CONCLUSION: The obese group had a lower step speed than the normal group (P < 0.05), the proportion of the first single support period decreased and the proportion of the second double support period increased when crossing the 11 cm versus 15 cm hurdles (P < 0.05). When walking on level ground, the margin of stability in the internal and external directions in the normal group was greater than that of the obese group (P < 0.05). When crossing the 4 cm hurdles, the margin of stability in the obese group was less than that in the normal group (P < 0.05). When crossing the 11 cm hurdles, there was no significant difference between the two groups in the anterior-posterior direction (P > 0.05), while there was a significant difference in the internal-external direction (P < 0.05). When crossing the 15 cm hurdles, the margin of stability in the obese group was lower than that in the normal group (P < 0.05). Overall, obesity decreases the body’s ability to control the body, reduces dynamic stability during crossing the barrier, and increases the risk of falls compared with the general population. In addition, compared with level ground walking, the decrease in the dynamic stability when crossing barriers is more significant in the obese group than the general population.
