SPEED RESPONSE AFTER STRENGTH TRAINING IN CHINESE BOXING ATHLETES

ABSTRACT Introduction: Chinese boxing demands the maximum potential from its practitioners. The quality of executions of single or multiple punches depends on adequate strength training, and the quality of speed is a crucial factor for victory in Chinese boxing competitions. Objective: Explore the effects of strength training on the speed of punches in Chinese boxing athletes. Methods: Eighteen Chinese boxers were selected by random sampling. The competitors perform functional exercises directed at strength training for ten weeks. Several key points of sports aerobics were comprehensively evaluated. Mathematical and statistical methods were applied in processing the data before and after the intervention. Results: The speed quality of Chinese boxing practitioners after strength training was statistically beneficial (P<0.05). Only the particular qualities of strength did not show significant differences among the four unique qualities of strength analyzed; there were significant differences among the other three abilities (P<0.05). Conclusion: The introduction of functional strength training into the physical training of high-level Chinese boxing athletes can significantly improve the quality of movement speed. Functional strength exercises are a safe and efficient form of exercise. This training protocol provides a good reference to compensate for the shortfall in conventional strength exercises. Level of evidence II; Therapeutic studies - investigation of treatment outcomes.


INTRODUCTION
The objective rule of Sanda, "play fast and slow, " is the principal Sanda players must follow whether the athlete's physical fitness, skills, or tactics are based on the movement's changes.The action quality of Sanda players is the key factor in competition and actual combat.In recent years, sports experts and scholars in China have begun to pay attention to cultivating functional ability.Scholars believe that functional exercise can enhance the spine's stability, improve neuromuscular control, and improve coordination of the upper and lower extremities. 1Through quantitative analysis, the author identified four types of exceptional physical fitness closely related to individual sports performance.This method can provide credible physical fitness indicators for coach training and material selection and effectively monitor athletes' exceptional physical fitness development.This makes Sanda teaching more scientific.

Research and results of main ingredients
In Sanda competition, the human body's energy metabolism is dominated by glycolysis, and its metabolite lactic acid will cause the body's muscle and brain function to decline, resulting in physical fatigue. 5Sanda players often use a variety of technical movements such as "far kick, close body, close body." If there is not enough professional ability, it is difficult for athletes to carry out long-term and challenging battles.
The 1-minute side kick and the 1-minute whip kick are specific strength and endurance indicators for the legs.And one minute of push-ups with arm clips, a flat push barbell, and one minute of punching is the strength and endurance of the upper body. 6These two skills are characterized by a technical movement that can perform leg technique and the Sanda technique continuously and repeatedly.In Sanda, athletes often use the technique of combining upper and lower legs to attack and counterattack.The existing literature shows that the combination of fist and foot has various forms and functions.(Table 1) (1)   T 0 represents the range of motion during practice.X j represents the movement type of Sanda training. 3The X i represents the load on the foot in different exercises.rank stands for the intensity level of high-level Sanda training.g(X 0 max ) represents the degree of injury of each level of Sanda athletes.O stands for weight.If it conforms to the above formula, then substituting formula (1) into formula (2) can obtain the ankle injury evaluation factor group of high-strength Sanda hands.

Comparison of performance of particular physical fitness before and after intensive training
From Table 2-5, it can be seen that there is no significant difference in the quality of exceptional strength among the four items. 7The quality of the other three majors is also very different.The 18 athletes must train in remarkable strength, endurance, extraordinary sensitivity, and movement speed.

DISCUSSION
Human body quality includes strength quality, endurance quality, speed quality, flexibility quality, and sensitivity quality.In Sanda events, players should fully use their physical potential to perform single or multiple technical movements with maximum efficiency. 8uring the practice process, the coaches should pay attention to the speed of practicing Sanda athletes and, at the same time, master the connection of various boxing methods, leg methods, throwing methods, punches, feet, etc.In this way, the comprehensive ability of Sanda players can be improved.In Sanda athletes, there is a lot of offensive and defensive information between opponents, so athletes must attack and defend quickly according to the different situations and their opponents.This process cannot be completed simply by simple reactions but also must consider the opponent's ability to react.Improving the choice and reaction time is very beneficial for Sanda players to make timely and accurate choices and judgments in various situations in attack and defense.This is the key to using Sanda techniques to strike opponents quickly, accurately, and harmoniously.Functional strength exercises strengthen the connection between an athlete's nervous system and muscles, increasing muscle control. 9This facilitates the transfer of power and reduces the selective response to Sanda players.Secondly, much functional strength intervention training uses both hands to complete the bodyweight exercise, which is relatively more straightforward.Although this training method does not have much effect on the deep muscles, it can also play a good role in conditioning.This makes the muscles of the body more flexible and flexible.In short, functional strength training can promote the function of the relevant muscle groups and accelerate the brain's commands to the muscles to quickly complete specific movements.

Factors affecting the response rate
The so-called "response" is that a person can accurately respond to each other's actions and goals, that is, how quickly the body responds to external stimuli.Signal stimulation is a training method that can improve reaction speed. 10The ultimate goal of Sanda players' reaction speed is to improve their anticipation and judgment.The effective method is to conduct actual combat in various situations constantly.Athletes constantly observe during the game to improve their anticipation and judgment.Coaches and players can also use their wits to create effective training methods.

Influencing factors of action speed
The manifestation of movement speed in Sanda generally includes the speed of Sanda, the speed of kicking, the speed of throwing force, the speed of evasion, and defense when defending.To speed up, you need to target the strength of the body.Developing a person's speed requires a lot of repeated exercise. 11There are specific exercises that can be used for actual training.It mainly includes decomposition, resistance reduction, transformation, boosting, and sound stimulation exercises.In addition, there are many ways and means of developing sports.For example, use "sprint." Exciting players through games and competitions can increase maximum speed.

Factors Affecting Movement Rate
Sanda athlete's action is a comprehensive reflection of reaction speed and action.Among Sanda athletes, the movement speed is mainly reflected in two levels: fast start and action.Quick start and quick movement can better adjust the distance with the opponent to achieve effective offense and defense.In actual practice, athletes should combine the movement of Sanda and adopt corresponding methods and measures.It mainly includes high-frequency footwork movement exercises, high-frequency footwork transformation exercises, and explosive thigh training.

CONCLUSION
In athletes' physical training, the four categories of particular endurance factor, unique sensitivity factor, action speed factor, and particular strength factor are dominant.Based on comparing four unique physical elements, this paper determines the particular physical fitness indicators that Sanda athletes must possess.Competitors participating in national competitions showed significant improvements after targeted functional training.Functional strength training can significantly improve the speed quality of Sanda athletes.
