摘要
空军飞行员暴露于高G载荷下导致颈部疼痛是一个特殊的职业问题,为了减少这方面的问题有必要进行特殊的颈肌强度训练。为了安全有效地进行颈肌强度训练,提供颈肌强度训练的最佳阻抗是非常重要的。本研究设计了NSE-1型飞行员颈肌训练器。为实现可变阻力和可变速度(CVR)肌力训练以及等长训练,本研究采用了自适应液压技术、传感技术、视觉和听觉生物反馈技术和信号处理技术,系统由机械部分(前屈后伸和左右侧屈训练器座椅、液压组件、力矩传递组件)、信号处理和生物反馈软件组成。为验证该训练器的有效性和安全性,对11名志愿者进行前屈后伸和左右侧屈的CVR训练和等长训练,每周三次,共6周。前屈、后伸、左右侧屈肌群的相对强度分别增长70.8%、83.7%、78.6%和75.2%。结果表明:应用NSE-1飞行员颈肌训练器进行颈肌训练,能安全高效地提高颈肌各肌群的强度。
Pain in the cervical region of air force pilots,who are exposed to high G-forces,is a specifically occupational health problem. To minimize neck problems,the cervical muscles need specific strength exercise.It is important that the training for the neck must be carried out with optimal resistance in exercises.The model NSE-1 neck training machine for pilots was designed for neck strengthening exercises under safe and effective conditions.In order to realize the functions of changeable velocity and resistant（CVR） training and neck isometric contractive exercises,the techniques of adaptive hydraulics,sensor,optic and auditory biological feedback,and signal processing were applied to this machine.The training system mainly consists of mechanical parts（including the chair of flexion and extension,the chair of right and left lateral flexion,the components of hydraulics and torque transformer,etc.）,and the software of signal processing and biological feedback.Eleven volunteers were selected for the experiments of neck isometric contractive exercises,three times a week for 6 weeks,where CVR training（flexion,extension,right,left lateral flexion） one time a week.The increase in relative strength of the neck（flexion,extension,left and right lateral flexion） was 70.8%,83.7%,78.6% and 75.2%,respectively after training.Results show that the strength of the neck can be increased safely,effectively and rapidly with NSE-1 neck training machine to perform neck training.
