Integrating physical fitness and technical training helps to improve the explosive force and endurance of track and field athletes and ensure their performance. In this paper, under the modern training concept, different kinds of physical training methods are designed to monitor the physical information of athletes, obtain the physical data of track and field athletes, so as to develop a reasonable training program and compare with the traditional training methods. In the flexibility test, the difference of seated forward body flexion was large, the experimental group increased from 15.5833 to 28.850, while the control increased from the initial 13.35 to 13.883.In the strength training, the one-minute sit-up changed from the initial 50.3333 to 83.17, while the control group only increased from the initial 49.8333 to 53, which indicates that the modern training concept is more effective than the In the endurance and sensitivity test, the meter run of the experimental group before and after training improved more significantly, changing from the initial 17.085 to 7.74, indicating that the modern training concept improves the endurance of the athletes and makes the athletes more explosive. It proves that the integration program based on the modern training concept improves the athletes' special performance and makes the athletes more explosive.
