This research aims to explore the effects of pace control Based Targeted Training Program on speed endurance, heart rate and 2000-m run performance in the young athletes whose age under 18 years. The research method, in the process of data collection, is the experimental method. In this method, the sample of this study consisted of 16 athletes who were assigned to two equally sized groups, an experimental group that received an eight-week targeted training program, and a control group that underwent traditional training. Measurement of speed endurance, heart rate after effort (beat/min), and 2000-m running time were included in the tests. There is a notable difference in the results of the experiment group versus the control group. After 8 weeks, the experimental group had a significant decrease in 2000-m run time and post-exercise heart rate and an increase in speed endurance, indicating the effect of the interval training that was prescribed in this study. In contrast to the experimental group, the control group had minimal improvement in most variables and their improvements were not enough, indicating that training that is less focused does not yield better results. This study contributes to the body of knowledge supporting this aspect of athlete development, by proposing a model of exercise training that emphasizes control of pace, based on high-intensity interval training, to improve athletes’ maintenance of high levels of performance and delay fatigue onset. Future research would be valuable in widening the sample of this work to participant groups with age and levels of sport but also exploring the use of specific training in other sports. It also recommends the use of these tools for training programs to be developed and analyzed more accurately through advanced tech including sensors and artificial intelligence tools. These results highlight the necessity for out-of-the-box thinking in training protocol to maximize sport and exercise performance and elite sports success.
