Introduction: The physical condition of soccer players in sports competitions has improved over the years. The optimal performance of their professional skills in competitive conditions has become essential for victory in soccer matches. Objective: This paper explores the effects of different methods employing strength training on soccer kicking techniques aiming at the set that best enables the accuracy of hits through its stability. Methods: 36 soccer players were randomly divided into the experimental and control groups, with no statistical difference in fitness and the comprehensive ability characteristics of the players. Both subjects were trained for 12 weeks; only the experimental group received the special strength training intervention for stability. The passing score of the curve ball in 20-meter dribbling was measured before and after training. The data were statistically treated. Results: The kicking accuracy of soccer players in the experimental group differed from before the test (P<0.01). There was also a significant difference in kicking accuracy in the control group (P<0.05). The 20-meter arc dribbling scores in the experimental group were statistically significant compared to those before the test (P<0.05). There was no significant difference between the control group and the test scores on curve ball passing scores in 20-meter dribbling (P>0.05). Conclusion: Functional strength methods to achieve the goal of improving kicking accuracy in athletes have been developed. Coaches should pay attention to physical training, an attitude that encourages players to achieve sufficient physical strength for soccer games with their kicking skills. Level of evidence II; Therapeutic studies - investigation of treatment outcomes.

Introduction With the development of increasingly competitive sports, coaches began experimenting with new methods for training athletes. Although among the most explored training methods is core strength training, a set of muscle groups that stabilize the trunk and hips, there are few studies on the effectiveness of this training dedicated to sprinters. Objective This paper investigates the training method of sprinters based on core strength training, studying the method and its influence on athletes’ performance. Methods Sixteen athletes with similar technical levels and physical fitness were selected, and professional coaches were invited to test the training samples. The athletes were randomly assigned to the experimental and control group (8 in each). The experimental group received core strength training for eight weeks, while the control group received general training. Results Off-core training affected the ankle joint angle of the support leg and the ankle joint angle of the swing leg (P < 0.01). After eight weeks of training, the performance of both groups improved without considerable differences. The high jump results of the athletes in the experimental group also improved compared to the previous training. Conclusion The physical function of athletes can be improved through core strength training to improve the sprinters’ competitive level and technical ability. Level of evidence II; Therapeutic studies - investigation of treatment outcomes.
