摘要: 目的:评定持续性军事职业活动对平衡能力的影响及视觉系统在其中的作用,为精准军事运动训练提供依据。方法:54名健康男性受试者,年龄(20.28±3.72)岁;身高(173.21±5.67)cm;体重(64.29±5.12) kg,在36 h的时间内完成多项军事科目,记录全程运动负荷(随机抽取11人),军事活动结束后进行睁眼平衡能力测试(54人)和闭眼平衡能力测试(随机抽取27人)。结果:内部负荷,与安静状态相比,军事职业活动中的心率(HR)、运动后的过氧消耗(EPOC)和运动冲量(TRIMP)值均显著增加(P<0.05);平衡能力,与睁眼安静值相比,军事职业活动后睁眼状态下整体、前后和左右方向的重心动摇距离和速度均显著增加(P<0.05),而整体、前后和左右动摇面积,前后和左右方向的最大动摇径,以及运动椭圆面积无显著变化(P>0.05);与闭眼安静值相比,军事活动后闭眼状态下平衡能力所有指标均显著增加(P<0.05)。结果表明视觉可控制持续性军事职业活动后人体重心动摇的幅度和面积。结论:长时间军事职业活动会损害人体的平衡能力,持续性的军事职业活动后,闭眼状态下平衡能力的破坏程度较睁眼状态大,表现为重心动摇幅度和范围的增加,表明视觉系统在控制姿态稳定方面起一定作用。

Abstract: Objective: To evaluate the effects of sustained military physical related activity on balance abilities and the role of visual system in it, so as to provide the basis for precise training. Methods: Fifty-four healthy males (age: 20.28±3.72 y, height: 173.21±5.67 cm; weight: 64.29±5.12 kg) were recruited in this experiment. Multiple military subjects were completed within 36 hours, and the workload was recorded (randomly select 11 people). After military activity, the balance abilities with opened eyes (54 people) and closed eyes (randomly selected 27 people) were evaluated. Results: In terms of internal load, the heart rates (HR), excess post-exercise oxygen consumption (EPOC) and training impulse (TRIMP) for all exercises were increased significantly in military activity compared with rest (P<0.05). Regard to balance abilities, compared to the rest with eyes-opened, the sway path-total (SPT), sway path-A-P ( SPAP ), sway path-M-L (SPML), sway V-total (SVT), sway V-A-P (SVAP), and sway V-M-L (SVML)after sustained military activity with eyes-opened were increased significantly (P<0.05), while sway maximal amplitude-A-P (SMAAP), sway maximal amplitude-M-L (SMAML), and area of 100% ellipse (AE) had no significant changes; Compared to the rest, all indicators after the military activity with eyes-closed were significantly increased (P<0.05). So vision could control the amplitude and area after the military activity. Conclusion: Sustained military related activity can damage the balance ability. After sustained military activity, the degree of damage of the balance ability in the closed-eyes is greater than that of the open-eyes, the amplitude and range of the center of gravity are increased, indicates that the visual system plays major role in controlling attitude stability.

Key words: sustained military activity, balance abilities, vision, load carriage
