目的探讨 2 1d - 6°头低位卧床和卧床运动训练对动态姿态平衡和控制功能的影响。方法 1 0名健康男性青年被试者分为卧床对照组和卧床训练组 ,每组 5人 ,卧床期间训练组每天进行 2次、每次 30min逐级增加负荷的头低位功率自行车训练 ;分别于卧床前和卧床后 2 1d进行了动态姿态平衡和双膝等速肌力的测试。结果与卧床前相比 ,对照组动态本体感觉得分和运动控制适应能力明显降低 ,双膝相对峰力矩明显降低 ,同时伴有绳肌与股四头肌峰力矩屈 伸比值的明显增加 ;训练组动态本体感觉得分和运动控制适应能力明显高于对照组 ,而绳肌与股四头肌峰力矩屈 伸比值无明显改变。结论 2 1d- 6°头低位卧床运动训练能够明显改善卧床后动态姿态平衡及其动态运动适应功能 Objective To investigate the effects of 2 1d - 6 ° head-down bed rest and bed rest training on dynamic posture balance and control function. Methods One hundred healthy male subjects were divided into bedside control group and bedridden training group, with 5 in each group. During the ambulation period, the training group was given 2 times a day, and the head low power bicycle training was gradually increased every 30 minutes. 2d before bed rest and bed rest after dynamic posture balance and knee speed isokinetic test. Results Compared with the pre-bedtime, the sensory scores of dynamic ontology and motor control in control group decreased significantly, the relative peak moment of knees decreased significantly, and the ratio of peak moment flexion and extension of hamstring to quadriceps femoris increased significantly. Dynamic ontology score and exercise control adaptability was significantly higher than the control group, while the hamstring and quadriceps peak moment flexion and extension ratio had no significant change. Conclusions 2 ld-6 ° head-down bed exercise training can significantly improve the post-bed dynamic posture balance and dynamic exercise adaptation
