This study aims to investigate the effect of using a ground contact angle sensor on improving start mechanics among youth short-distance sprinters. The researcher employed an experimental approach using a control and experimental group design. The training program was applied to a sample of (n = 12) sprinters over an intervention period of (6) weeks. The experimental group followed a training program supported by ground contact angle detection technology, while the control group continued with conventional training. The study relied on objective biomechanical measurements, including a ground contact angle sensor (electronic sensor), high-speed video analysis, and force platforms to measure contact angle, ground contact time, and the horizontal force ratio (RF%). The results revealed statistically significant improvements in favor of the experimental group in ground contact angle and contact time compared to the control group, with statistical significance values (p 1.0), in addition to a noticeable increase in the horizontal force ratio (RF%). The study concludes that the use of a ground contact angle sensor effectively enhances start mechanics in sprinters. It also emphasizes the importance of integrating modern biomechanical technologies into youth training programs to improve competitive performance efficiency, and this achieves one of the sustainable development goals of the United Nations in Iraq which is (Good Health).
