使用动态建模工具，我们的目标是得到一个最小的动态模型的手运动在篮球弹跳，并评估必要的调整模型时，高度限制实验变化。10名右撇子受试者在离地0、30、60和90厘米处进行了四个系列的30个球的弹跳。增加高度导致手的振幅，周期时间和非线性项的运动的贡献增加。通过对相位和虎克平面上手部运动学的定性分析，提出了一个货车der Pol+Duffing极限环模型。定量分析表明，该模型是适当的，并保持不变时，高度是不同的。
Using dynamical modelling tools, our objective was to derive a minimal dynamical model of hand movement in basket-ball-bouncing, and to evaluate the necessary adjustments in the model when height constraints are experimentally varied. Ten right-handed subjects performed four series of 30 balls bouncing with the feet at 0, 30, 60 and 90cm above the ground. Increasing height led to an increase in hand amplitude, cycle time and contribution of non-linear terms to the motion. Qualitative analyses of hand kinematics portrayed in phase and Hooke plane suggested a Van der Pol+Duffing limit-cycle model. Quantitative analyses revealed that this model was adequate and remained invariant when height was varied.
