On the one hand, it not only improved competitive sports continuously created new sport items, but also improved the training equipment and training environment, promoted the movement technology and changed the sport values. On the other hand, modern technologies also contributed to the alienation of technology, and weakened the physical fitness activities, and lead competitive sports into deformity errors, which made fair competition become empty, and generated a series of uncivilized unfair social problems. Therefore, we appeal of positive effect of modern technology. In the same time, confront and suppress its negative effects, to ensure that competitive sports may develop in healthy environment under the conditions of modern science and technology.
