This paper utilizes VR technology to construct a virtual sports training situation and proposes a sports training feedback teaching mode based on VR technology. Aiming at the VR high-resolution scene generation technology, it analyzes the image super-resolution recovery algorithm based on multi-frames, introduces the regularization solution method, and, on this basis, proposes a generalized entropy variational image super-resolution recovery algorithm to realize better VR panoramic visual teaching. Taking Taekwondo movement training in K-school as the research content, we compared the learning attitude change, the influence of special physical quality, and the technical mastery ability of Taekwondo movement between the experimental group and the control group. The evaluation results found that the technical score of movement completion ability after the experiment was 94.98±2.36 in the experimental group and 85.79±5.32 in the control group. The quality of physical education teaching can be improved by using VR technology in teaching mode.
