AB  - 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.
