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.

Introduction: The exercise of functional strength in a sprinter can play an essential performance gain to propulsion. Functional training can significantly affect the sprinter, preventing injury and making better use of physical training. The sprint interval training method has been widely recognized and applied. Objective: This paper explores the effect of functional strength training by the sprint interval training method on the strength quality of sprinters. Methods: This paper uses random sampling to select 30 male college sprinters as research subjects. The volunteers were divided into two groups according to the performance of the 100-meter speed project: All the essential data of the subjects who passed the T-test were without statistical difference P>0.05. Both groups perform daily training. Functional strength training was added to the experimental group by interval start training with a full 12-week cycle. The strength data of the athletes were measured before and after the experiment, measured, and discussed statistically. Results: The indicators showed significant differences, except for the normal left supine position support test, unchanged by the presented intervention(P<0.01). After the experiment, all indicators were statistically significant compared to the control group (P<0.01). The performance of the groups in the ball exercise, static jump, and vertical jump was significantly improved (P<0.01). Conclusion: Functional strength exercise can improve sprinters’ body control and stability. The sprint interval method can also improve the speed of upward force transmission. This conclusion is significant for formulating the strength training plan designed for sprinters. Level of evidence II; Therapeutic studies - investigation of treatment outcomes.
