The calculation of joint torque generated by competitive swimwear using the skin strain simulation was investigated in this paper. An anisotropic hyperelastic model considering cyclic deformation of swimwear fabrics was introduced in order to reproduce the mechanical characteristics of swimwear fabrics. The material parameters of the proposed model were approximated by using the cyclic tensile loading test results. In addition, the pressure measurement tests were conducted to measure the pressure of swimwear. The theoretical pressure calculated by the proposed model showed similar trend of pressure measurement tests. Next, the stress calculation of swimwear was investigated using the proposed model and the skin strain simulation. The skin strain simulation is able to get the human skin strain of during various motions. Finally, hip joint torque generated by the swimwear was calculated from the calculation results. Therefore, the calculation of hip joint torque generated by swimwear enables the new design of swimwear considering the value of hip joint torque.
