APPLICATION OF FUNCTIONAL TRAINING ON PHYSICAL FITNESS IN BASKETBALL

ABSTRACT Introduction: Basketball is a predominant competitive sport among the masses. Its practice requires scoring as many points as possible within a specific time limit, manifesting a short-duration, high-intensity intermittent training session. To meet the sport's requirements, the athlete must have ample directional control, rapid changes in speed, and good jumping ability. Objective: Verify the effects of functional training on basketball players aiming to improve explosive power, stability, and agility. Methods: 18 college basketball players were randomly selected as volunteers for the investigation. They were randomly divided into experimental and control groups. Only to the experimental one was functional physical training added during routine training. The trial lasted for eight weeks. All participants were tested for agility, strength, speed, endurance, power, and cartilage repair before and after the experiment. Finally, a comprehensive statistical data analysis was performed. Results: There were significant differences between the experimental group and the control group in push-ups, 3200-meter run, physical acuity detection, 17 sidelines, and running items, and touch height (P<0.05). In the experimental group, there was no significant difference in high school grades (P>0.05). There was significant statistical significance in the supine project, the 3200-meter athletics project, the 17 sideline projects, and the touchdown project (P<0.05). Conclusion: The physical fitness of the experimental group improved significantly after functional physical training. After routine physical training, the control group athletes had significantly positive absolute strength and endurance results. Overall, functional fitness training is superior to conventional fitness training. Level of evidence II; Therapeutic studies - investigation of treatment outcomes.


INTRODUCTION
Young basketball players' muscle explosiveness, endurance, and flexibility are all in the stage of rapid development.If coaches can carry out reasonable physical exercise, they can develop their physical functions better and exercise their formidable willpower.In the daily exercise of basketball players, functional physical training has become a focus of physical education in colleges and universities.This must cause enough attention. 1This paper takes 18 young players as the research object.This article compares conventional physical training with functional physical training.The training period for each set is eight weeks.The learning effect of each stage is carried out by comparing the evaluation index.This paper mainly analyzes the differences between functional physical and conventional physical training in improving the physical fitness of young basketball players.

METHOD Experimental subjects
This paper selects 18 college basketball players for investigation.The subjects were randomly divided into two groups.One class is used as the experimental group.One group served as a control group. 2 There was no significant difference in general data and physical fitness between the two groups before the experiment (P<0.05).

Test plan
Functional physical training includes three aspects: First, basic functional physical training.Coaches focus on building a solid foundation in terms of physical stability, physical strength, and more.The second section is regular physical exercise.Athletes mainly train from the aspects of endurance, speed, flexibility, coordination, and so on.This stage lays a solid foundation for the following special physical training.The third stage is specialized technical training. 3Its goal is to enable athletes to develop solid fundamentals in professional competition.Based on the above research results, this paper established an index system for evaluating the effectiveness of functional physical training.(Table 1) Regular physical training uses high-intensity exercise.Functional fitness is a dynamic chain that treats the body as a whole.It focuses on constructing motion models, focusing on the control of nerves over the body when the athlete is unstable.

Sports injury model in sports training
In this paper, a random vector model of Q dimension is established according to M = (M 1 , M 2 ,..., M Q ) when athletes are over-training in basketball. 4The second-order moment of the impact of basketball players' excessive physical training on joints is expressed as follows J is a constant vector in a basketball player's overload exercise, the exercise load parameter that affects the athlete's joint injury.In this paper, the linear transformation matrix of the athlete's joint injury factor is constructed according to the J j ´ J j = 1, J = 1,2...q limited model.
In this paper S 1 replaces Q and becomes the initial variable M 1 , M 1 , ... , M Q in the construction of the basketball excessive physical training model.
Combined with statistical principles, this paper analyzes the correlation between basketball players' excessive physical training and joint injury factors. 5At the same time, this paper comprehensively evaluates basketball players' excessive physical training.
(( )) (( , )) In the basketball player's physical training model, the larger the value of Var(S 1 ), the more information S 1 contains on the influencing factors of sports.J j refers to the correlation between excessive physical training of basketball players and the factors affecting it.Θ is the covariance of M. In this paper, the following formula derives a model of an athlete's injury due to excessive exercise load.( , , , ) This paper uses the following formula to describe relevant matrix of the joint damage model caused by excessive physical training of basketball players In this paper, the damage model of the knee joint caused by exercise load was constructed according to the following formula during basketball players' excessive physical training.

Mathematical and statistical methods
This paper uses the data processing program of SPSS21.0 to describe the correlation between the experimental and control groups. 6The significant difference level was controlled at 0.05.

Ethical Compliance
Research experiments conducted in this article with animals or humans were approved by the Ethical Committee and responsible authorities of Guangzhou Sport University following all guidelines, regulations, legal, and ethical standards as required for humans or animals.

RESULTS
After eight weeks of functional physical training three times a week, the test results of 9 players in the experimental group are compared with those before the test, as shown in Table 2.There were significant differences in the 30-second average of the standard sit-up items, the 3200-meter long-distance running, the physical sensitivity test item, the 4-time basketball court sideline 17-turn-back item, and the running touch-height item test in the experimental group compared with those before training (P<0.05).The results showed that the experimental group's performance in the above aspects was significantly improved after functional physical training. 7In the in-situ touch height test, the test scores of the experimental group did not increase significantly (P>0.05).After the functional physical training, the experimental group showed significant improvement in the test scores of the other five test indicators except for the in-situ touch height project.
In the same training time, the scores of the nine athletes in the control group in the six experimental items in the conventional physical training are compared with those before the test, as shown in Table 3. From Table 3, it can be seen that the scores of the athletes in the control group in the standard sit-ups, the 3200-meter long-distance running, the 17 items on the edge of the basketball court, and the running touch-height items after receiving traditional physical training have significant statistical significance (P <0.05).The control group's performance in the above aspects was significantly improved after physical training. 8There was no significant difference in the mean test scores in the physical sensitivity test of the in-situ touch height and the restricted site (P>0.05).The control group has generally made significant progress in the other four test items after physical training, except for in-situ touch height and physical acuity detection in limited areas.
This paper analyzes the results of the six experimental items in the control and experimental groups to verify their effectiveness further.Table 4 lists the conclusions of this analysis.
The scores of both the experimental and control groups were significantly improved in the regular sit-up event and the 3200-meter reciprocal event (P>0.05).This suggests that functional fitness training has no significant advantage over regular physical activity. 9There was no significant difference in the test scores of the two groups in the in-situ touch height project (P>0.05).This suggests that functional fitness training has no significant advantage over regular physical activity.The physical sensitivity of the control and experimental groups was significantly improved (P<0.05).This shows that functional physical training has obvious advantages in improving the performance of the above items compared with conventional physical training.

DISCUSSION
The comprehensive qualities of basketball players include explosiveness, endurance, speed, agility, and flexibility.Routine physical and functional physical training complement each other in the physical training of youth basketball teams.So, coaches should pay attention to balanced physical training. 10Physical training should ensure overall effectiveness and increase the proportion of specific physical training.Only by ensuring the balance and rationality between the two can better promote the comprehensive quality development of young basketball players.The overall physical fitness test should be carried out first in the physical training of youth basketball.After fully understanding the individual differences of athletes, coaches conduct targeted training.In regular physical training, coaches must organically link technique and physical training.This enables him to improve his physical quality and technical abilities.For example, in cultivating youth's comprehensive qualities such as strength, speed, and endurance, various competitions can be carried out regularly to improve
