To explore the efficacy rules and mechanisms of core strength-dominated exercise intervention for adolescent track and field athletes with idiopathic scoliosis (ISS), 14 male adolescent track and field athletes aged 16-18 years with mild ISS (Cobb angle 10-25 degrees) were selected as research objects. An 8-week core strength intervention was conducted using a self-control design, with three testing nodes: pre-intervention (T0), 4 weeks (T4), and 8 weeks (T8). Spinal morphology and functional indicators were monitored using a DR digital X-ray machine (GE Definium 8,000) and SpineScan IV electronic spinal measuring instrument, and one-way analysis of variance was performed using SPSS 26.0. The results showed that the intervention efficacy was characterized by “functional priority and morphological lag”. After 4 weeks, spinal flexibility (thoracic backward extension increased by 47.8%) and lumbar stability (left rotation increased by 22.0%) were significantly improved, while there was no statistical difference in morphological indicators. After 8 weeks, the threshold for morphological improvement was broken, with an average reduction of 6.12 degrees in Cobb angle (improvement of 45.8%), and the spinal morphology and function were improved synergistically. There was segmental differentiation in intervention effects, and the improvement in lumbar rotation (45.7%) was significantly better than that in thoracic spine (18.3%). Conclusion: 8 weeks is the optimal intervention cycle, which can achieve synergistic improvement of morphology and function and adapt to the athlete’s training cycle. The constructed “cycle – effect – segment” theoretical framework provides theoretical support and practical basis for precise intervention of ISS in adolescent track and field athletes.
