【摘要】：研究目的:通过使用不同的高强度间歇训练方式对无训练基础的年轻女性进行训练,探讨高强度间歇训练是否会对其姿势稳定性产生即时影响,以及不同的训练手段是否有明显差异,从而为高强度间歇训练是否适合此人群以及合适的高强度间歇训练手段提供理论依据和实验支持。研究方法:受试者为北京体育大学无训练背景的女学生10名,在专业体能教练的带领下分别进行功率自行车高强度间歇训练和徒手高强度间歇训练。在训练前、训练后即刻、训练后10分钟、训练后20分钟和训练后30分钟,分别在闭眼单脚站立和睁眼单脚站立状态下,采用红外高速运动捕捉系统(Motion Analysis Raptor-4,200Hz)与三维测力台(Kistler 9281CA,1000Hz)同步采集受试者的运动学和动力学数据。研究结果:不同的训练手段对压力中心相关指标(动摇轨迹长、最大动摇径、包络面积、平均摆速、前后摆速、左右摆速)重心相关指标指标(动摇轨迹长、最大重心偏移、平均摆速、前后摆速、左右摆速、上下摆速、动摇角度和动摇角度变化速度)无明显差异。分别在两种训练结束后即刻,压力中心指标和重心的前后、左右最大偏移都会明显增大,但在10分钟后基本恢复到无差异。闭眼双脚站立的状态下,两种训练方式的影响趋势相近。而在睁眼单脚站立的状态下,徒手训练对各个方向上都有较强的影响趋势。研究结论:单次的高强度间歇训练会即时地明显削弱无训练基础的年轻女性的姿势稳定性,10分钟左右即可基本恢复,但功率自行车与徒手两种训练方式并没有明显差异。
[Abstract]:Objective: to explore whether high intensity intermittent training will have an immediate impact on their posture stability by using different high intensity intermittent training methods to train young women without training basis. And whether there are significant differences in different training methods, so as to provide theoretical basis and experimental support for whether high-intensity intermittent training is suitable for this population and suitable high-intensity intermittent training methods. Methods: the subjects were 10 female students without training background in Beijing University of physical Education. Under the leadership of professional physical fitness coaches, high intensity interval training and unarmed high intensity interval training were carried out respectively. Before training, immediately after training, 10 minutes after training, 20 minutes after training and 30 minutes after training, standing on one foot with closed eyes and standing on one foot with open eyes, The kinematic and dynamic data of the subjects were collected synchronously by infrared high speed motion capture system (Motion Analysis Raptor-4200Hz) and three dimensional force measuring station (Kistler 9281CA, 1000Hz). Results: different training methods have different training methods for pressure center related indexes (shaking trajectory length, maximum shaking diameter, envelope area, average pendulum speed, forward and rear swing speed, left and right swing speed). The center of gravity correlation index (shaking trajectory length, maximum center of gravity deviation, There was no significant difference in average swing speed, forward and rear swing speed, left and right swing speed, upper and lower swing speed, shaking angle and shaking angle. Immediately after the two kinds of training, the maximum deviation between the left and right will increase obviously before and after the pressure center index and the center of gravity, but it will recover to no difference after 10 minutes. Under the condition of closed eyes and feet standing, the influence trend of the two training methods is similar. However, in the state of standing with open eyes and one foot, unarmed training has a strong influence on all directions. The results show that a single high intensity interval training can significantly weaken the posture stability of young women without training basis, and can be basically recovered in about 10 minutes, but there is no significant difference between the two training methods of power bicycle and unarmed hands.
