Samba dance is a factional part of sports dance. It forms a sports dance system with modern dance. According to the method of sports biomechanics experiment, the dynamic parameters and changing rules of fork foot pressure dynamic distribution characteristics are summarised, which can provide theoretical reference for further study of the basic law of samba dance. From the point of view of sports biomechanics, this paper analyses the rotation of athletes, and combines the knowledge of biomechanics with the rotation characteristics of samba dance. Studies have shown that in the comparison of general parameters, the different indicators of the foot pressure have a certain regularity in different action stages. There were no significant differences between the test group and the control group in terms of walking speed, relative speed, step size, relative step size, foot contact area time, and duration.

桑巴舞是体育舞蹈的派系部分。它与现代舞蹈形成了运动舞蹈系统。根据运动生物力学实验方法，总结了叉脚压力动态分布特征的动力学参数和变化规律，为进一步研究桑巴舞的基本规律提供理论参考。从运动生物力学的角度，分析了运动员的旋转方式，并将生物力学知识与桑巴舞的旋转特性相结合。研究表明，在比较一般参数时，足压的不同指标在不同的动作阶段具有一定的规律性。测试组与对照组之间的步行速度，相对速度，步幅，
