Core strength training is crucial for improving athletes' performance in competitive sports. It has become a popular method in training, but there is still room for improvement in theoretical knowledge, training methods, and assessment. By focusing on core stability and strength, athletes can enhance their overall capacity and target specific muscle groups. However, there is a disconnect between theory and practice, leading to incomplete assessments and a lack of basic research. To address this, innovative research is needed to elevate the scientific level of core strength training in competitive sports and reduce ineffective training. The goal is to provide practical methods and guidelines for effective core strength training in competitive sports.
