Sports monitoring equipment that integrates advanced sensing technology has attracted widespread attention in recent years. Hence, we proposed a TPU/PLA 3D printing film triboelectric nanogenerator (TP‐TENG) to monitor basketball player posture for training effectiveness evaluation. By introducing carbon fibers, TPU/PLA/Carbon film with conductive and positive triboelectric properties was prepared. According to results, the peak power density is 58.38 mW m−2 when the load resistance of 30 MΩ is matched. Nevertheless, when TP‐TENG encounters wrinkles and continues to work for a period of time, its output performance will tend to stabilize. And the open‐circuit voltage (VOC), transfer charge (QSC), and short‐circuit current (ISC) increase to 91 %, 92 %, and 92 %, respectively, almost the same as their original values. Furthermore, the TP‐TENG sensor can recognize human posture in different basketball motion posture, including skipping, squatting, walking, running. This work can help to promote the application of 3D printing TENG in basketball sports monitoring. [ABSTRACT FROM AUTHOR]

This study evaluates the effectiveness of the eight weeks of training for defensive rebounding upon the performance of male basketball players at Sabaragamuwa University of Sri Lanka. One of the most critical elements in the game of basketball is that of defensive rebounding. It controls the outcome of the game by not allowing opponents to get many scoring opportunities. The study involved a pre-test and post-test design with three participants selected from the university's basketball team. The design of the program was to increase vertical jump height and general rebounding technique. The results showed improvements in rebounding performance for all subjects. There was a very marked improvement in average two-point shooting accuracy from pre-test to post-test subjects moved from about 25% to 30% of accuracy. The overall result was significant, in that statistical analysis established a positive significant difference between the pre- and post-training tests. These findings prove that, with focused and intensive training programs, basketball skills can be improved even at the university athlete level. The research supplements the literature of skill development in basketball and lays a base for further research on such training intervention projects to improve game performance. This study proves that defensive strategies should be integrated into regular training for all competitive basketball teams. [ABSTRACT FROM AUTHOR]

The purpose of this study is to determine the influence of psychological mood on the performance and mental health of athletes during VR training. The study involved representatives of both men's and women's basketball teams from universities in China (62 girls and 65 boys, whose average age was 18.2). The participants were divided into 2 groups. Both groups trained regularly, except the experimental group used VR technology, while the control group did not. To study the physical performance of respondents, a complex psychophysiological test was used. The Warwick-Edinburgh Mental Well-Being Scale (WEMWBS) was used to assess the psychological mood and mental health of respondents. The VR training has been proven to increase the psychological attitude of basketball players during the training. Specifically, it has a positive effect on the psychophysiological performance indicators and mental health of athletes. Prospective research will be aimed at a comparative study of the impact of VR technology in the training process on the results of basketball players and representatives of other team sports.

The traditional basketball training monitoring method has some limitations, such as relying on manual judgment and subjective evaluation, and being limited by equipment and environmental conditions. In order to solve these problems, an optical sensor system is designed and constructed in this study, which can capture the optical signals during basketball training in real time and convert them into digital data. These data are analyzed and processed using deep learning algorithms to extract features related to basketball training. A large number of experiments and tests have verified the effectiveness and accuracy of this optical sensor method. The experimental results show that this method can monitor and record the key information of basketball movement track, players' movements and skills in real time, and can quantitatively evaluate the quality and effect of basketball training. Through the combination of deep learning technology and optical sensors, non-invasive, high-precision and real-time monitoring can be achieved, which provides a powerful auxiliary and evaluation means for the training of basketball players, and helps to improve the training effect and level.

(1) Playing basketball entails intense anaerobic activities, including short sprints, sudden stops, rapid direction changes, and jumps. Common training methods for enhancing players' anaerobic fitness comprise sprint training, jump exercises, and interval training. The aim of this research was to compare the impact of three sprint-training methods on anaerobic capacity. (2) The study included 25 male basketball players, aged 16–18 years, from the National Youth League in Israel. The participants were divided into three groups: sled-pushing, sled-dragging (intervention), and no sled (control) sprint training. Twice-weekly sessions were conducted over a five-week period, in addition to their regular basketball training. Pre- and post-intervention tests included vertical and horizontal jumps, 5 and 20 m sprints, and agility tests. (3) The study revealed significant improvements in the horizontal jump in the sled-pushing group (≈3%) and a near-significant improvement in the sled-dragging group (≈2.9%). Less improvement was seen in the control group (≈1.8%). No improvements were seen in the vertical jump performance in any groups, despite an increase in the sled-pushing group (≈5.5%) and in the sled-dragging group (≈3%) compared to that in the control group (≈1.2%). Finally, no improvements were seen in sprint speed and agility in any group. (4) Despite the modest improvements observed in most tests across the three groups, the consistent and significant enhancement seen in the sled-pushing and sled-dragging groups compared to that in the control group suggests potential benefits for sled assistance in anaerobic training in young basketball players.

Featured Application: Quantifying the external and internal load of the wheelchair basketball will allow the coaching staff to analyze the physical demands of the players during training. The systematic and programmed control and evaluation of the external and internal load of high-performance athletes during training sessions and high-level competitions allows the coaching staff to know a great amount of information to evaluate the physical condition of the players and the tactical positioning as well as to identify optimal performance. Therefore, this study aimed to analyse the external and internal load of wheelchair basketball players during training and competition matches considering the functional classification of the players. WIMU PROTM inertial devices were used to collect the data. As independent variables, the sporting context and the functional classification were selected, and as dependent variables, the variables related to the external and internal load were established. The results reported significant differences between the contexts, with higher values in the competition than in the training sessions considering the internal and external load. Taking into account the functional classification, it is shown that the player with a higher functional classification obtained more differences and higher values. Understanding the external and internal load of the players during training and competitions is very important to personalise the training load according to the demands of the competition. It allows development of a progressive and modular training programme of loads to obtain the best performance. Consequently, injury risk of players due to overload will also be reduced.

Background: Visual attention is very important in basketball shooting, which is a prerequisite for forming good muscle proprioception and improving the shooting rate. The ability of visual instant searching information in the process of free throw plays an important role in the mobilization of free throw percentage. The aim of this study is to explore the fixation characteristics of athletes at different levels in the process of free throw shooting and to provide scientific basis for improving the free throw training of basketball players. Methods: A total of 20 expert basketball players, 20 general basketball players and 20 novice basketball players participated in the experiment. Participants in the three groups wore eye tracker to make free throws, and analyzed the difference of visual attention among the three groups. Results: The expert group had fewer number of fixations on the front, bottom, topright, and top-right areas of the basket than the general and novice groups. The expert group also had smaller saccadic amplitudes than the other two groups. In terms of fixation duration, the expert group had longer fixation duration on the front and top areas of the basket than the other two groups, while in the top-right and bottom-right areas, the expert group had shorter fixation durations. The pupil dilation of the expert group was larger than that of the other two groups. Conclusion: During the free throw process, the expert group had a clear attentional focus, concentrated fixation points, efficient information search, and precise processing. Profound basketball knowledge, proficient skills, and accumulated experience are the foundation of visual efficient search and precise processing during free throw attempts, and they are also the prerequisite for ensuring a high free throw shooting percentage.

Basketball players should train at intensities similar to those recorded in competition, but are the intensities really similar? This study aimed to quantify and compare the internal and external intensities assimilated by professional basketball players, both in training and in competition, according to context and the specific player position. Players from the same team in the Spanish ACB competition were monitored for three weeks. The sample recorded intensities in 5 vs. 5 game situations in both training (n = 221) and competition (n = 32). The intensities, as dependent variables, were classified into kinematic external workload demands (distances, high-intensity displacements, accelerations, decelerations, the acceleration:deceleration ratio, jumps, and landings), neuromuscular external workload demands (impacts and player load), and internal workload demands (heart rate). They were measured using inertial measurement devices and pulsometers. The playing positions, as independent variables, were grouped into guard, forward, and center. According to the context, the results reported a significant mismatch of all training intensities, except jumps, with respect to competition; these intensities were lower in training. According to the playing position, inside players recorded more jumps and landings per minute than point guards and outside players in training. In turn, inside players recorded a higher average heart rate per minute than outside players in this same context. There were no significant differences in intensity according to the playing position in the competition. Considering the context–position interaction, no differences were observed in the intensities. Adjusting and optimizing training intensities to those recorded in competition is necessary. [ABSTRACT FROM AUTHOR]

In Mainland China, the sports training process of most players is highly homogenized, the convergence of which makes them ineffectively be identified with their individual and specific profile and difficult for them to play the sports according to their strengths and characteristics. Moreover, existing sports training software does not differentiate between player types to provide customized persona. Therefore, efficient and personalized methods need to be provided to guide players towards more autonomous sports training. Current research shows that gamification design in the process of sports training can transform players' unique conscious behaviors into habits, thus increasing their autonomy. However, the current gamification design in sports training is only based on uniform gamification elements and does not take into account the player's motivation and gamification experience, which is one of the main reasons for the homogenization of sports training. Therefore, this study aimed to identify factors that contribute to the design of gamification systems in the field of sports training, as well as to determine the relationship between players' gamification experiences during sport. It will help the researchers to explore in depth the possibilities of learning environments for youth basketball training with the development of gamified experiences. This design-driven study performed both offline and online questionnaire research (N = 198), which was analyzed with the method of a 7-point Likert scale as well as the assistance of SPSS, identified potential for the establishment of a framework for analysing preferences for gamification design elements in the context of basketball training for young players. Based on the results, this paper finds that there is a correlation between immersion and achievement in gamification experiences and proposes a framework for gamification system design in the field of sports training and offers insight that may enable the development of gamification designs that can motivate players.

At present, the effects of chronic ankle instability (CAI) on the biomechanics of the ankle joint in the three-step layup of basketball players are not clear. This work aims to thoroughly investigate the impact of CAI on the biomechanical characteristics of the ankle during the execution of a three-step layup in basketball players. Thirty male basketball players were stratified into distinct groups—namely, a CAI group and a non-CAI group—comprising 15 individuals each, based on the presence or absence of CAI. Demographic attributes, including age, weight, height, and the Cumberland Ankle Instability Tool (CAIT) score, were subjected to rigorous statistical examination within both athlete cohorts. The research employed four Whistler 9281CA 3D force measuring platforms (Switzerland), recording at 1000 Hz, in conjunction with eight camera motion analysis systems (USA), functioning at a frequency of 200 Hz. The study recorded maximal plantarflexion angle, inversion angle, dorsiflexion angle, and peak ankle dorsiflexion moment across the subjects during the distinct phases of push-off, landing, and the ensuing landing period. The findings notably exhibited that within the context of the one-foot push-off phase, the maximum ankle inversion angle was notably diminished in the CAI group as contrasted with the non-CAI group, demonstrating statistical significance (t = − 3.006, P < 0.01). The CAI group exhibited a lesser alteration in ankle inversion angle compared to the non-CAI group. Notably, during the one-foot landing period, the CAI group demonstrated a significantly greater maximum ankle inversion angle in contrast to the non-CAI group (t = 8.802, P < 0.001). Furthermore, the CAI group displayed a substantially larger maximum dorsiflexion angle at the ankle joint compared to the non-CAI group (t = 2.265, P < 0.05). Additionally, the CAI group exhibited a prolonged peak time for ankle dorsiflexion moment as compared to the non-CAI group (t = − 2.428, P < 0.05). Collectively, the findings elucidated a reduction in the maximum ankle joint inversion angle during the one-foot push-off phase in individuals with CAI. Furthermore, increased maximum inversion angle and maximum dorsiflexion angle of the ankle joint were observed during the one-foot landing period, alongside a lengthening of the peak time of ankle dorsiflexion moment. These results contribute valuable insights into the selection of training methodologies for basketball players afflicted by CAI. [ABSTRACT FROM AUTHOR]

Functional training, since Beijing Olympic Games, from field of medical rehabilitation to field of competitive sports, advanced scientific training concepts and training methods have gradually been recognized by domestic competitive sports workers and coaches. Therefore, functional training should be developed to grass-roots team to lay a solid foundation for sustainable development of competitive sports in our country. In this paper, a complete set of functional physical training program is designed by using methods of literature, expert interviews, experiments, mathematical statistics, and logical analysis. Finally, it is found that functional training can improve physical coordination of men's basketball. And symmetry, flexibility of athletes' ankle joints, thoracic spine, shoulder joints and stability of knee joints and cores have been improved, reducing probability of sports injuries, providing a theoretical basis for innovative scientific training of male basketball players in my country.

Background: Currently, the scientific evidence available on plyometric training in young basketball players is limited. Objectives: The aim of this study was to analyze the effects produced by plyometric training over a period of 8 weeks, with a frequency of two weekly training sessions, combining vertical and horizontal force vectors. Methods: The study involved 28 young men (14.54 ± 0.6 years, a height of 182.76 ± 7.1 cm and a body weight of 68.05 ± 9.8 kg) high-level basketball players and aimed to investigate the effects of this training program on athletes at different maturational states, specifically based on their peak height velocity (PHV) and post-pubertal (post-PHV) stages. Results: Substantial improvements were achieved in the subjects who have carried out this type of plyometric training in all the parameters evaluated related to the improvement of the jump, linear speed and change of direction. Conclusions: Therefore, it is crucial to provide valuable information to trainers and physical trainers, enabling them to improve and individualize the conditioning work for optimal performance of their athletes.

This study examined the effects of combined change of direction (CoD) and plyometric training on sand in basketball players' jump, sprint, and CoD performances. In total, twenty-five male professional basketball players (age, 24.1 ± 4.2 years; height, 192.5 ± 8.0 cm; body mass, 92.6 ± 11.6 kg) participated in a pre-season intervention study over seven weeks, where two teams completed an identical speed training protocol, either on sand or on a hard surface, while a third team served as the control. All participants followed their regular pre-season training, while the intervention groups additionally performed the training protocol twice weekly. A repeated-measures ANOVA (rANOVA) showed significant interaction effects on the countermovement jump (F = 14.90, p < 0.001), pivot–step–jump test (F = 8.09, p = 0.002), 10 m sprint time (ST) (F = 4.18, p = 0.050), and 20 m ST (F = 8.49, p = 0.002). Moreover, an rANOVA showed significant interaction effects for the CoD performance regarding total time (F = 5.70, p = 0.010) and average velocity prior to the CoD (F = 8.40, p = 0.002) and after the CoD (F = 3.89, p = 0.036). As such, the findings suggest that sand-based training elicits kinematic adaptations, increased muscle activation, and a shift towards concentric force development that all contribute to enhanced athletic capabilities.

This study tested if, in elite basketball players' training, the integration of a cognitive component within a multi-component training (MCT) could be more effective than an MCT with motor components only to improve both physical and cognitive skills. To this purpose, we designed an MCT focussed on sprint and agility incorporating a cognitive-motor dual-task training (CMDT) focussed on decision-making speed. Specific tests on sprint, agility and decision-making, and event-related potential (ERP) during the latter test were evaluated before and after the intervention. Thirty elite basketball players were recruited and divided into an experimental group executing CMDT integrated into the MCT and a control group performing the motor MCT (without cognitive components). The MCT with CMDT session was performed by four athletes simultaneously that executed different circuits. One circuit was the CMDT which was realized using interactive devices. Results on physical performance showed that only the experimental group improved in sprint and agility and also shortened response time in the decision-making test. At the neural level, the experimental group only shows an increase in the P3 ERP component, which has been associated with a series of post-perceptual cognitive functions, including decision-making. In conclusion, CMDT implemented within an MCT, likely stimulating more than physical training cortical plasticity, could be more effective than a motor MCT alone in improving the physical and cognitive skills of elite basketball players in five weeks only.

Several studies have confirmed the efficacy of flywheel eccentric overload training in order to improve or increase muscle volume and strength, as well as several performance-related fitness attributes, but to date, there are no studies that have reviewed the effects of these training methods in basketball. Therefore, the present systematic review aimed to collect the updated information about the influence of flywheel training on performance of basketball players. A search in four electronic databases (PubMed, SCOPUS, Web of Science, and Google Scholar) was conducted up to November 20, 2022. Articles were selected as valid for review if: (i) they were an experimental trial published in English; (ii) participants were basketball players without illnesses or injuries, and (iii) a rotational inertial overload method was used as a performance-dependent variable. A total of 93 articles were found. After filtering procedures, only seven studies were considered in this systematic review. In the selected studies, 203 participants were included, 58 females and 145 males. Focusing on basketball related performance variables, all the studies included the countermovement jump (CMJ), while five included sprinting and a change of direction test (COD). The results showed an improvement in performance-related variables associated with basketball (sprint, CMJ, and COD) through the use of inertial methods. Improvements were reported in professional, semi-professional and amateur players as well as both male and female players. However, given the low number of studies, additional investigations on this topic are warranted before a "clear picture" can be drawn concerning the effects of flywheel eccentric overload training in basketball players.

A limited number of studies focus on the effect of core training on basketball players' athletic performance and skills. This systematic reviewaimed to comprehensively and critically review the available studies in the literature that investigate the impact of core training on basketball players' physical and skill performance, and then offer valuable recommendations for both coaches and researchers. Thedata collection, selection, and analysis adhered to the PRISMA protocol. English databases, including Ebscohost, Scopus, PubMed, Web of Science, and Google Scholar,were searched until September 2022. A total of eight articles were included, with four studies comparing the effects of core training versus traditional strength training or usual basketball training. All studies investigated the impact of core training on athletic performance. The findings revealed that core training can help players improve their overall athletic and skill performance, particularly in the areas of strength, sprinting,jumping, balance, agility, shooting, dribbling, passing, rebounding, and stepping. In addition, core training, particularly on unstable surfaces,as well as combining static and dynamic core training,improvebasketball players' athletic and skill performance. Despite the relativelylittle evidence demonstrating the effect of core training on endurance, flexibility, and defensive skills, this review demonstrates that it should be incorporated into basketball training sessions.

For a long time, the level of endurance quality of our male basketball athletes is not high, and there is a gap with the strongest countries in Europe and America. The former head coach of Chinese men's basketball team diagnosed the biggest problem of Chinese men's basketball team and Chinese youth men's basketball team is the poor quality of endurance. It is especially important to strengthen the endurance training of our basketball players and improve their endurance level. However, from the current situation, the teams in the training due to the lack of standards for endurance quality training has led to a great blindness in endurance quality training. The endurance quality level evaluation of young male basketball players is a classic multiple attribute group decision making (MAGDM) issue with vague, inconsistent, and indeterminate information. The 2-tuple linguistic neutrosophic sets (2TLNSs) is an appropriate form to express the indeterminate decision-making information in the endurance quality level evaluation of young male basketball players. Therefore, in this paper, the 2-tuple linguistic neutrosophic numbers CLVA (2TLNN-CLVA) is built based on traditional close value (CLVA) method and applies it to evaluate the endurance quality level of young male basketball players. Finally, a numerical example for evaluating the endurance quality level of young male basketball players has been given and some decision comparisons are also conducted to further illustrate the advantages of the 2TLNN-CLVA method.

The α-actinin-3 (ACTN3) gene rs1815739 (C/T, R577X) polymorphism is a variant frequently associated with athletic performance among different populations. However, there is limited research on the impact of this variant on athlete status and physical performance in basketball players. Therefore, the aim of this study was twofold: (1) to determine the association of ACTN3 rs1815739 polymorphism with changes in physical performance in response to six weeks of training in elite basketball players using 30 m sprint and Yo-Yo Intermittent Recovery Test Level 2 (IR 2) tests, and (2) to compare ACTN3 genotype and allelic frequencies between elite basketball players and controls. The study included a total of 363 individuals, comprising 101 elite basketball players and 262 sedentary individuals. Genomic DNA was isolated from oral epithelial cells or leukocytes, and genotyping was performed by real-time PCR using KASP genotyping method or by microarray analysis. We found that the frequency of the ACTN3 rs1815739 XX genotype was significantly lower in basketball players compared to controls (10.9 vs. 21.4%, p = 0.023), suggesting that RR/RX genotypes were more favorable for playing basketball. Statistically significant (p = 0.045) changes were observed in Yo-Yo IRT 2 performance measurement tests in basketball players with the RR genotype only. In conclusion, our findings suggest that the carriage of the ACTN3 rs1815739 R allele may confer an advantage in basketball. [ABSTRACT FROM AUTHOR]

In basketball, reaction speed is important: how quickly a player reacts to an external stimulus, finds the right solution and implements it on the playground, often determines the outcome of the match. The aim of the study is to analyze the peculiarities of the course of mental processes and to identify their relationship with the technical readiness of basketball players at the training stage of preparation. To assess mental processes, we used: a proofreading test, a test with a school ruler, an individual minute, and a tapping test. Standards were used to check technical readiness: the number of hits from 10 free throws, the time of the throw-in motion, and the total number of hits in the ring, shuttle running with ball driving (5x10). The study involved girls aged 15-16 years who had been playing basketball for at least 5 years and had sports grades. The basketball players were examined in September 2021 and May 2022. In this study we found statistical differences between the initial and final levels in terms of the number of errors in the proofreading test (27.91%, p<0.05), the reaction rate to a moving object (27.57%, p<0.05), the duration of the individual minute (13.59%, p<0.05), the result of the tapping test with the right and left hands (the differences were 21.82%, 15.46%, respectively, p<0.05), as well as the coefficient of functional asymmetry (35.67%, p<0.05). The data obtained require a deeper study of ways to increase the effectiveness of training activities that allow influencing traditional training. [ABSTRACT FROM AUTHOR]

Basketball's physical demands and wide appeal make numerous societal applications feasible. Through a short-term physical and psychological exercise program, this study sought to improve collegiate basketball players' physical, psychological, and technical skills during their off-study period. Twenty-four university basketball players older than 18 and in good physical and mental health participated in the study. Twelve participants were assigned to the experimental group and twelve to the control group. The instruction program lasted three weeks and consisted of four two-hour weekly sessions. The experimental group received specialized instruction in shooting, passing, and dribbling. In contrast, both groups received training in fundamental skills, aerobic fitness, vertical jumping, arm and trunk muscle endurance, and rudimentary playing skills. The study's results revealed that both unique and mixed training improved maximal oxygen uptake, with both groups experiencing similar improvements. Aerobic fitness and strength improved roughly 30% in the specific training group and 20% in the combined training group. Moreover, performance in three basketball technical skills increased by 17 to 27% in both groups, with a tendency for shooting and passing skills to develop more significantly in the training group. These results suggest that an exclusively on-court basketball training program (special training) is as effective as a combined training program at enhancing aerobic and anaerobic fitness. Based on the provided fit indices, the adaptability of the green enterprise model to basketball players demonstrates an acceptable and decent fit. The findings emphasize the potential for targeted and specific training to improve basketball players' physical and technical abilities during their off-season. [ABSTRACT FROM AUTHOR]

Objective: As the basketball level rises, the paradox that the theoretical research of psychological tactics lags behind practice becomes more pronounced. This study is undertaken to enhance the pupils' psychological tactics training and scientific level. This study's primary purpose is to examine the effect of long-term training and competition on basketball players' propensity for critical thinking. Methods: The author blends pertinent critical thinking theories from Marxist legal theory with psychological and tactical elements. Using literature, expert interviews, surveys, and quantitative statistics, the importance of critical thinking in the psychological and tactical application process is explored from the standpoint of information gathering, processing, and decision selection and application. Using SPSS 17.0, the studied data and pertinent data were obtained. Results: Based on the CUBA Chinese University Basketball Association's test of the critical thinking tendency, it can be determined that basketball players have developed some elements of the critical thinking tendency after long-term training and competition. Conclusion: In the context of modern basketball's evolution, the cognitive ability of decision-makers has a significant impact on decision-making. To attain scientific and rational decision-making in the current competitive climate, decision-makers must possess high decision-making thinking skills. Basketball players have a solid training foundation in critical thinking. [ABSTRACT FROM AUTHOR]

The aims of this study were to determine the relationship between vertical jumping performance, linear speed, change of direction speed (CODs) time and the COD deficit (CODD) in adolescent basketball players and to analyze the CODD between faster and slower players based on linear speed performance. Thirty-eight male basketball players (age: 15.47 ± 0.51 years; body height: 185.19 ± 5.67 cm; body mass: 71.87 ± 7.29 kg) completed countermovement jumps (CMJ) with and without an arm swing, squat jumps (SJs), linear sprints at 20 m with split times at 5 and 10 m, the pro–agility test and the zig-zag tests. Furthermore, the CODD was calculated as the difference between the 20 m linear speed result and CODs time in both COD tests. Pearson and Spearman analyses were used to determine the correlations between power-speed-related variables and the CODD. Moreover, independent t-tests and Cohen's d effect size (ES) were used to analyze the differences between the faster and slower players in the CODD. Moderate to strong significant negative correlations were observed between the CODD in the pro-agility test and linear speed at 5 m, 10 m, and 20 m (r = –0.55 to –0.46), while moderate negative significant correlation was found between the zig-zag CODD and SJs (r = –0.37) as well as small positive significant correlation between the CODD in the zig–zag test and the eccentric utilization ratio (EUR) (r = 0.23). Additionally, faster basketball players displayed significantly higher CODD values performing the pro-agility test. In summary, these findings underline the complexity of COD performance and the importance of remodeling traditional training programs in basketball players. [ABSTRACT FROM AUTHOR]

In order to scientifically explore the effective path of strength quality training of basketball players and improve the effect of strength quality training of basketball players, this paper takes young basketball players as the research object and comprehensively observes the changes and improvement of strength quality by building a strength training monitoring system for basketball players. On this basis, it is proposed to integrate blood flow restriction and basketball players' special strength training. Through the comparison with the traditional resistance strength training method, it is found that after 8 weeks of experimental comparison, the athletes' strength quality test indicators show that the average 3RM of the experimental group 1 bench press is 65.2 kg, the experimental group 2 is 65.7 kg, and the experimental group 3 is 72.2 kg. The average performance of the traditional control group was 55.4 kg. Compared with the traditional group, the average performance of the three experimental groups in bench press was significantly improved, which also verified the feasibility of this method in strength quality training.

Competitive performance ability is the on-the-spot performance of basketball players' comprehensive use of technical and tactical, physical, and psychological abilities. Because basketball players' competitive performance includes many evaluation contents and influencing factors, it is difficult to comprehensively and objectively use a single qualitative analysis or quantitative statistics for evaluation and measurement. Based on the analytic hierarchy process (AHP) and intelligent fuzzy comprehensive evaluation, this research establishes a hybrid model, which is applied to evaluate the performance of basketball players. Based on the actual needs, this research uses the relevant theories in the discipline of sports training, with abundant empirical data materials, combined with the specific practice of basketball players' training and competition, starting from the concept of clear sports intelligence, to further determine the indicators of the basketball players' sports intelligence evaluation system and weights, construct a set of evaluation system about basketball players, and use this as a standard to evaluate and judge the current situation of basketball players' sports intelligence.

Wrist joint plays an indispensable role in our daily life. The injury of wrist joint has a great influence on the fine movement of the hand and upper limb. For example, you cannot do joint movements, you cannot carry things, and life is very inconvenient. It is necessary to distinguish the types of wrist disorders and take effective rehabilitation methods in time. Wrist joint has a great impact on people's life and work, and the rehabilitation of wrist joint has become a research hotspot in rehabilitation medicine and medical engineering. Carpal tunnel syndrome is the most common peripheral nerve entrapment disease in clinical practice, with a very high incidence. According to data, the incidence of carpal tunnel syndrome in the general population abroad is 1%-5%, while that in special populations is as high as 14.5% above. In order to solve the problem of rehabilitation of wrist joint, using electrospinning technology, the polymer solution is prepared into nanofiber materials with strong adsorption and good filterability under the action of high-voltage electric field. And using some small-sized nanofibers that are similar to organs in shape and structure, as well as their excellent degradability and biocompatibility, this material is used in the research of wrist joint movement rehabilitation. In this paper, sports rehabilitation training is carried out on the wrist joint of basketball players, and the nanofiber material is effectively combined with sports rehabilitation training. By comparing the rehabilitation of athletes who did not use nanofiber materials, the role of nanofiber materials in sports rehabilitation was studied. This article analyzes the three parts of the radial joint, the wrist joint, and the ulnar joint before and after the sports rehabilitation training for basketball players with functional impairments and compares the sports rehabilitation of the basketball players without nanofiber materials. This article analyzes the three parts of the radial joint, the wrist joint, and the ulnar joint before and after the sports rehabilitation training for basketball players with functional impairments and compares the sports rehabilitation of the basketball players without nanofiber materials.

With the development of industry and the progress of science and technology, more and more new technology is gradually applied to the movement of error correction. This not only relieves workers of unneeded burdens by making their task more straightforward and error-free, but it also improves production efficiency. Deep neural networks are one of these new technologies that have exploded in popularity in recent years, with applications in a variety of industries. Of course, the application in image recognition must not be less, image recognition technology based on deep neural network has become more mature, and the error rate of recognition is now much lower than human vision recognition. So at present, some industrial detection is gradually from human vision detection to computer vision detection. This study discloses a basketball action error correction method based on deep learning image recognition, which includes the following steps: receiving each frame of basketball image captured from the fitness video, recording the corresponding time of each frame of fitness image, and preprocessing each frame of fitness image; the preprocessed basketball image was fed into the human joint recognition model, and the human joint recognition model calculated each human joint in the fitness image and output its position coordinates. According to the coordinate position of each joint orderly line, the human skeleton diagram is obtained; the human skeleton diagram is compared and assessed in accordance with standard fitness action, and the nonstandard basketball image is generated to realize basketball action repair. A basketball action error correction system based on deep learning picture identification is also disclosed in the invention. The system and method are capable of efficiently addressing the difficult challenge of comparing fitness movements with and without music rhythm. [ABSTRACT FROM AUTHOR]

Background: The accumulation of physiological stress and the presence of inflammation disturb iron management in athletes during intense training. However, little is known about the mechanisms regulating iron levels in athletes during training periods with low training loads. In the current study, we analyzed the effect of an acute exercise on early responses of iron and iron regulatory proteins at the end of such training periods. Methods: The study was performed at the end of competitive phase of training. A total of 27 trained female basketball players were included in the study after application of the inclusion/exclusion criteria. The participants performed an incremental exercise on a treadmill. Blood samples were taken before the test, immediately after exercise, and after 3 h of restitution. Parameters, such as interleukin (IL) 6, hepcidin, ferritin, transferrin, hemopexin, and lactoferrin levels, total iron-biding capacity (TIBC), unsaturated iron-biding capacity (UIBC) were determined by using appropriate biochemical tests. Results: The level of iron increased significantly after exercise, and then decreased within next 3 h restitution. Except for iron levels, only TIBC levels significantly increased after exercise and decreased to baseline level during rest period. No significant changes in the levels of hepcidin, IL-6, and other proteins related to the iron homeostasis were observed. Conclusions: The increases in iron level after acute exercise is short-term and transient and appear to have been insufficient to induce the acute systemic effects in rested athletes.

Players in modern basketball have a lot of physical contact, a lot of bumps, and a lot of physical struggles. The competition for the ball, whether in the air or on the ground, is fierce, putting higher demands on the players' physical abilities. Coaches frequently use plateau physical training, which is very effective in developing athletes' cardiopulmonary function, among many other training methods. The proportional length and active area of arms are obtained using the skin color model of the human body, the angle and posture information of each joint is extracted from dynamics, and the 3D posture of arms and dynamic arms is trained and recognized in this paper, which is based on Kinect. The findings revealed that mild hypoxia in the plateau significantly lowered basketball players' performance and that basketball players' maximum heart rate and 1-minute heart rate recovery in high-intensity exercise were lower than those in flat area training.
