摘要

人才培养是体育运动中天赋识别的必然结果,是一个涉及提高生物力学能力和生物运动能力的过程。通过对可训练性的测量,可以客观地评估和监测发展进度。本研究介绍了一种实用的方法,利用运动学数据评估运动控制这一可训练因素。研究的重点是建立运动学数据与肌肉力量和动态平衡变化之间的关系。它说明了可穿戴技术如何在功能训练计划中评估可训练性。研究人员选取了 26 名女大学生,将其分为干预组和对照组,以调查运动控制的可训练性。干预组进行了 24 次台阶有氧运动。安装在 S1 上的单个惯性测量单元(IMU)捕捉了这些有节奏练习过程中质心的摆动运动曲线。分析表明,不同解剖平面的线性挺举变异幅度可反映出训练对核心和下肢肌肉的强化作用。此外,研究结果表明,在整个训练过程中,动态平衡对节奏变化的适应主要受步幅的影响。内外侧线性挺举的变化反映了这种适应性。本研究提出的最低仪器配置方法对于人才培养监测非常实用。该方法说明了适当放置单个 IMU 所记录的运动学数据如何成为教练监测、评估和量化受训者在长期运动发展过程中所取得进步的丰富信息来源。

Linear jerk variability evaluation in measurements of motor control trainability: Could kinematic variables encompass information about strength and dynamic balance?

As the natural conclusion of talent identification in sports, talent development is the process that involves improving biomechanical capacities and bio-motor abilities. The development progress can be objectively assessed and monitored through measurements of trainability. This study introduces a practical methodology to assess motor control as a trainable factor using kinematic data. The study focused on establishing the relationship between kinematic data and changes in muscle strength and dynamic balance. It illustrates how wearable technology can assess trainability during a functional training programme. Twenty-six female university students were selected and divided into intervention and control groups to investigate motor control trainability. The intervention group performed step aerobics exercises for 24 sessions. A single inertial measurement unit (IMU) mounted on S1 captured the oscillatory motion profiles of the centre of mass during these rhythmic exercises. Analysis revealed that the amplitude of linear jerk variability in different anatomical planes could reflect core and lower limb muscle strengthening caused by training. Furthermore, the results indicated that the dynamic balance adaptation to the changing tempo throughout the training programme was dictated primarily by step width. The mediolateral linear jerk variability reflected this adaptation. The minimum instrumentation approach proposed by this study could prove very practical for the talent development monitoring. The methodology illustrates how the recorded kinematic data from an appropriately placed single IMU could become an information-rich source for the coach to monitor, assess and quantify the trainee's progress during long-term athletic development.
