Simulation-based basketball training movement optimization and teaching guidance strategy

When basketball players play against each other in a game, better coordinated balance can give them a better advantage. This paper briefly introduces the coordination balance and core strength of basketball players. Twenty basketball varsity members were selected from Chengdu College of University of Electronic Science and Technology of China as subjects for the test. The athletes were randomly divided into a control group and an experimental group. The control group received regular strength training, and the experimental group received core strength training in addition to regular training. Both groups underwent isometric muscle strength test, coordination and balance test and shooting percentage test before and after training. The results demonstrated that muscle group strength increased in the control group after conventional training, but the experimental group showed more significant improvement in muscle group strength after additional core strength training; the experimental group had better coordination and balance ability after core strength training; the experimental group had a significantly higher shooting percentage after core strength training due to the improvement of coordination and balance ability.

Purpose: The aim of this study was to objective the effect of balance control ability of 12weeks core strength training and blood biochemical indexes of University Basketball Players. Methods: Fourteen basketball players received 12 weeks of core strength training, three times a week for 90 minutes, separated by 1 week pre-training and 12 weeks after training. All subjects were tested for the balanced ability indexes and routine biochemical indexes which included movement area of standing on one foot, moving velocity, BU,CK,WBC,HB,T,C and T/C, when they open and close eyes. Results: The results indicate that when the subjects stand on one foot, the movement area and velocity of one foot are significantly reduced( P<0.01)after 12 weeks of core strength training. A significant decrease (P<0.01) of difference of bilateral center of gravity center movement area occurred at opening eyes. On the contrary, A significant increase (P<0.01) of difference of bilateral center of gravity center movement area occurred at closing eyes. Bu and CK were significantly lower than pre-training (P < 0.05), WBC, HB, T and C increased significantly (P > 0.05), while t / C decreased slightly (P > 0.05).Conclusion: Results provide preliminary evidence that twelve weeks of core strength training can improve the balance control ability of basketball Players, enhance the body's ability to adapt to the training load, and keep the body function at a better level.

Implementation of an anterior cruciate ligament (ACL) injury prevention program (IPP) has been recommended to coincide with the adolescent growth spurt as risk factors increase during and following this phase of maturation. Physiological responses to load during this stage of growth may result in a differing maximum heart rate (HRmax) during intense exercise. Understanding the relationship between physiological responses to load and maturation stage may result in more effective IPP in youth athletes. PURPOSE: To examine the effects of maturation on HRmax in adolescent soccer players over a six-week training program. METHODS: 34 female soccer players participated in a 6-week training study (age 13.3±1.5yrs; height 158.7±6.9cm; mass 50.0±9.6kg). Maturation groups were determined based on percent of adult stature (PAS) with 88-94% representing pubertal (n=9, PAS 91.6±2.0%) and 95-100% representing post-pubertal (n=25, PAS 97.7±1.7%). Three 30 minute sessions, separated into plyometric, resistance, and core strength training, were completed each visit for a total training time of 90 minutes three times per week. Participants wore HR monitors during each plyometric session. The initial exercises were adapted from ACL IPP, and intensity of each exercise was progressed weekly following the second week of training (5 total phases). HRmax was calculated for each participant during each session and averaged weekly. A linear mixed model (p<0.05) was used to determine the effects of HRmax over the six-week intervention in pubertal and post-pubertal female soccer players. Average HR during the first week of training was used as a covariate. RESULTS: A significant interaction of maturational group and training week was found (p<0.04) with HRmax. A main effect of training week was found in both pubertal (p<0.001) and post-pubertal (p<0.01) groups. HRmax was significantly increased in both groups (week 1 to week 3, p<0.05) following the first two technique focused weeks of plyometric program with the pubertal group (184.3±4.7 BPM) having greater HRmax compared to the post-pubertal group (172.7±2.2 BPM) during week 3. CONCLUSIONS: Physiologic responses to load was dependent on maturation stage and should be further examined in relation to reduced risk of injury following IPP.

Background: The effectiveness of simulation-based training has been examined in various sports. However, considering the effect of gender and sport on training, it would be interesting to evaluate simulation-based training in female basketball. Objective: The purpose of the study was to examine the effect of simulation-based training on physical fitness and performance indices in female basketball players. Methods: Sixteen female semi-professional basketball players were randomly assigned to experimental (n=8; age, 25±2 years; weight, 62±9 kg; height, 167±8 cm) or control (n=8; age, 24±1 years; weight, 57±9 kg; height, 170±8 cm) groups. The experimental group participated in a six week basketball simulation training program including running with different speeds (jogging to sprinting), agility, jumping, and shuffling. Both groups performed the Cooper 12 min run, line drill, an adjusted T-test, 20 ms print, the Sargent vertical jump and basketball exercise simulation test before and after six weeks of the study period. Control and experimental groups performed typical basketball training, three times weekly. The overall training volume was similar for both groups. Results: The perceived exertion was higher in the simulation-based training than control (p&lt;0.05) group. The findings of this study indicated a significant increase in VO2 max (p=0.001), anaerobic power (p=0.009), explosive leg strength (p=0.036), and total distance covered in basketball exercise simulation test (p=0.001) and decrease of the meantime of one round of basketball exercise simulation test (p=0.001) in the simulation training compared to the control group. Conclusion: Generally incorporation of the simulation-based training in conditioning programs is recommended for improving aerobic, anaerobic and leg explosive strength of basketball players.

In order to help basketball players to carry out training more efficiently and reasonably, and obtain the technical specifications of their shootings timely in training, this paper constructs a shooting detection algorithm to assist basketball players in training. Firstly, Hough transform algorithm is applied to the shooting video to detect the trajectory of the basketball in the shooting. By analyzing the basketball trajectory, it is found that the best shooting angle should be 49° to 51°. Then, the basic principles of HOG feature and SVM are studied, and the HOG feature of basketball hit and miss is extracted to train the SVM classifier. Finally, the training model was tested, and the classification accuracy of basketball hit or miss was 91.75%. This study will help the basketball players in their training and also could be applied to other ball games.

Background and Aims: Functional strength training, as a new training method, has now been widely applied in professional sports and competitive sports, and other fields. Changing the traditional basketball strength training methods has become an urgent task at present. However, in the field of basketball sports training, there are relatively few related training applications to improve the jumping quality of basketball players. Therefore, in this study, adolescent basketball players with a certain competitive level were selected as the research subjects. By applying functional strength training methods, the influence of functional strength training on jumping quality was explored. Theoretical analysis and experimental verification were conducted on the application of functional strength training in basketball practice for the reference of coaches and athletes. In the hope of contributing a little to the process of promoting the scientific training of basketball players. Methodology: Thirty male athletes from the men's basketball team at China Jiuquan Vocational and Technical College were recruited and divided into three groups: weight training, functional strength training, and a control group (n=10 per group). Leg muscle strength was measured using high jump tests at baseline, after 4 weeks, and after 8 weeks of training. Data were analyzed using SPSS software to calculate the mean differences and standard deviations across groups. Results: These findings indicate that weight training and functional strength training play essential roles in enhancing jumping performance by improving take-off speed, endurance, and whole-body coordination. Conclusion: These findings indicate that weight training and functional strength training play essential roles in enhancing jumping performance by improving take-off speed, endurance, and whole-body coordination. Comprehensive training programs should integrate strength, speed, and coordination exercises alongside technical skill development to optimize performance.

Objectives:To assess dynamic balance and vertical jump pre and post Suspension training and Plyometrictraining in competitive basketball players. Methods:24 basketball players aged 18-24 were selected and randomly assigned to threegroups namely Suspension training, Plyometrics and the control group. Supervised sessions were held for 8 weeks, 2 times a week for 45 minutes. Pre and post assessment for dynamic balance and vertical jump was done. Results: Suspension training and Plyometric training both have shown a positive effect on dynamic balance( p &lt;0.007 ) except for anterior direction and vertical jump (p &lt;0.007) in basketball players. The results of the control group have shown a lot of variability as no specific training was given for dynamic balance and vertical jump. Conclusion:Suspension training and Plyometric training have positive effect on dynamic balance and vertical jump height. However, no training method is found to be more efficient than the other.

Physical activity of basketball players during the match is usually defined by the amount of work (distance, quantity of actions, duration, etc.) and intensity of work (frequency, rate, speed, etc.) by evaluating the interaction of these components in practice. However, duration of repeated sprints and recovery intervals are different depending on different situations of the game. The aim of this study was to determine and evaluate how different types of interval training affects physical and functional capacity of basketball players. Twelve highly trained basketball players (age 21 ± 1.9 y, weight 86.2 ± 5.8 kg, height 189.6 ± 6.8 cm, BMI 23.9 ± 1.3 kg×m-2, standing reach 247.8 ± 9.6 cm), voluntarily participated in this study. All participants had 12 ± 1.9 y of basketball training experience with ~10 h training per week. A single-group repeated-measures study design was selected for this study. The mode of interval training (IT-1 and I-T2) by manipulating the number of repetitions, rest time and length of running distance, but maintaining the same amount of work (900 meters), work to rest ratio (1 : 5) and recovery time (5 mins) was selected as independent variable. Running speed, duration, fatigue index, dynamics of recovery and response to a physical load (heart rate, oxygen quantity changes in muscle and blood lactate concentration) was evaluated as dependent variables. IT-1 consisted of three series of ten 30 meters shuttle sprints (15 + 15 m) with a change of direction of 180°, intercepted by 30 s of passive recovery. IT-2 consisted of three series of twenty 15 meters sprints, intercepted by 15 s of passive recovery. Research revealed that during different modes of interval training, influenced not only by the length of the running distance but also by the change of direction, different average running speed prevailed. During both modes of interval training, fatigue index suffered by basketball players was significantly different. Insignificant differences of oxygenation between interval trainings shows that activity of aerobic reactions is not related to the type of training. The changes of heart rate confirms this trend, but significant increase in both trainings shows fatigue of parasympathetic nervous system. Study showed that during different modes of interval training, the activity of anaerobic reactions is different. Although there was a slower running speed, longer work duration and lower fatigue index in IT-1, blood lactate concentration after training was higher by 4.49 mmol/l (p < 0.001) than IT-2. This allows to assume that part of the aerobic reactions are related to the elimination of metabolites and reimbursement of energy supplies in working muscles. Keywords: running speed, fatigue index, heart rate, blood lactate.

Basketball is one of the popular sports in the world, and physical performance is becoming increasingly important in basketball as the game evolves. The aim of the study was to investigate the effects of a 3-week modified complex training on athletic performance of women's national basketball players. An experimental study involved the participation of 12 highly trained female basketball players (national team of Bosnia and Herzegovina). Observed variables before and after 3-weeks of modified complex training were 300 yards test, 20-yards test, lane agility and beep test. Means and standard deviations for each of the variables were calculated, and differences pre-to-post performance changes were examined using a paired sample t-test. Three weeks of specific complex training sessions show a statistically significant increase in all tested variables, 300 yards (p≤.001); 20 yards (p≤.001); Lane agility (p≤.001) and beep test (p=.028). It can be concluded that applied complex training program has significantly improved studied parameters of condition preparation of elite female basketball players.

Gonzalo-Skok, O, Dos' Santos, T, and Bishop, C. Assessing limb dominance and interlimb asymmetries over multiple angles during change of direction speed tests in basketball players. J Strength Cond Res 37(12): 2423-2430, 2023-The aims of this study were to establish whether directional dominance is displayed during change of direction (COD) tasks across various angles, to determine the angle-variation data for the asymmetry magnitude and direction, and to analyze the relationships in COD performance (completion time and COD deficit) across tasks. Twenty-four young (U-16 to U-20), highly trained male basketball players performed a 10-m linear sprint test and four 10-m COD tests (45°, 90°, 135°, and 180°) in left and right directions. Change of direction performance was determined via total times and COD deficit, and asymmetry comparisons were made between faster and slower directions and dominant leg (DL) (i.e., first step leg in lay-up) and nondominant leg (NDL). No significant differences (p > 0.05) were found between DL and NDL for any task excluding 45° COD (p < 0.05, effect size [ES] = 0.44-0.78), but significant differences were established between faster and slower sides for all angles (p < 0.05, ES = 0.70-1.28). Levels of the agreement in directional dominance during COD tasks were generally poor to slight (k = -0.14 to 0.14), excluding a fair agreement between COD45 and COD90 (k = 0.34). Correlations between COD total times and COD deficits between angles were moderate to very large (r = 0.32 to 0.81) and moderate to large (r = -0.30 to 0.55), respectively. Players displayed superior COD performance in a particular direction across various angles. This directional dominance is not necessarily consistent between angles, thus highlighting the angle-dependent nature of COD performance. Consequently, practitioners should investigate multiple angles and directions to create a COD angle profile for their athletes.

Abstract. Topicality. Experts note that one of the key problems directly impacting the competitiveness of Ukrainian basketball players in the international arena today is their physical fitness. The training of skilled basketball players within an annual training cycle should include not only a model structure but also programs for various types of training, tailored for use in specific mesocycles with indicated means and load components. The purpose of the study is to determine the main methodological approaches to adapting the content of physical training for skilled basketball players to the stages of the annual training cycle (using the preparatory period as an example). Materials and methods of research. The study was theoretical and practically oriented, employing the following methods: analysis and generalization of scientific and methodological sources, as well as internet content, to find modern methods of physical training; examination of regulatory documents regarding the educational process in higher education institutions; analysis of the competition calendar for student teams; and pedagogical observation of the training process within the annual macrocycle. Research results. Planning the training process for an annual preparation cycle is a crucial function for a coach in sports management.
