中文摘要：

运用物理学知识建立了前臂投掷运动的动态模型。该文通过模拟仿真的方法，研究了肌肉的发力模式对角速度的影响。结果表明，在不同的发力模式下，角速度呈现不同的变化形式。尽可能快地发力至最大，可有效地提高角速度。

英文摘要：

Based on physics, a dynamic model of forearm throwing motion is formulated. Then the influence of muscle force model on angular velocity is studied by simulation. It turns out that angular velocity shows different variations with different force model, and angular velocity can be effectively improved by increasing the force to the maximum as soon as possible.
