科学领域:

  • 生物力学 生物力学
  • 人类表现的人类表现.
  • 战术训练 战术训练 战术训练

背景情况:

  • 动态射击对于战术运动员来说至关重要,但性能标准并不统一.
  • 现有的关于静态射击技能的研究对影响动态性能的因素缺乏深度.
  • 了解这些因素对于优化战术运动员准备能力至关重要.

研究的目的:

  • 研究静态射击能力,运动速度,载荷能力和生物力学对动态射击能力的影响.
  • 在战术运动员中"移动射击"时识别准确度的关键预测因素.
  • 为策略性射击技能的标准化评估和培训协议提供信息.

主要方法:

  • 24名男性战术运动员在不同的负载 (无负载,半套,全套) 和速度条件下执行静态和动态射击任务.
  • 使用无线惯性测量单元记录了部,膝盖和脚运动.
  • 使用从声学目标得分的平均辐射误差 (MRE) 来量化射击精度.

主要成果:

  • 静态射击精度 (MRE) 和运动期间在双肢支中花费的时间是动态MRE的重要预测因素.
  • 静态MRE每增加1厘米就相当于动态MRE每增加0.66厘米.
  • 双肢支时间的每1%增加与动态MRE的0.13厘米增加相关.

结论:

  • 具有较差静态射击精度和较长双肢支时间的战术运动员表现出较低的动态射击精度.
  • 下肢关节角度,载荷能力和运动速度并没有显著影响动态射击性能.
  • 在战术"移动射击"场景中的新型运动特征需要进一步调查.
