The invention relates to the technical field of human motion analysis, in particular to an intelligent method for obtaining pressure between lower limb joints during sprint through resistance torsion, which comprises the following steps: step 1, obtaining a plurality of six-degree-of-freedom values, a resistance torsion value and a video acquisition result; 2, preprocessing is carried out, and an effective six-degree-of-freedom value is obtained; 3, performing preprocessing to obtain a three-dimensional coordinate value; 4, obtaining kinematics and dynamics numerical values representing the pressure between the lower limb joints; 5, kinematics and dynamics numerical values of the pressure between the lower limb joints are obtained through the motion capture model, three-dimensional motion analysis is carried out, and a final tracking motion numerical value is obtained; compared with the prior art, when a sportsman carries out drag resistance running training, the sportsman can know the waveform change of the
