The impact of adapted exercises in basketball on the perception of the difficulty and physical enjoyment of students with overweight.

The purpose of this study was to investigate the effect of the adapted basketball cycle on the perceived level of difficulty and physical enjoyment in girls and boys with overweight. Sixty-six students with overweight (aged 16-18 years) were randomly assigned to an experimental group (EG, n = 32 including 20 boys and 12 girls) and a control group (CG, n = 34; including 21 boys and 13 girls). Statistical analysis also showed that the levels of perceived difficulty decreased significantly after of seven-week of the adapted basketball cycle in both boys (Δ% = - 0.27; p < 0.001; and girls (Δ% = - 0.36; p < 0.001). There was no significant difference in students who participated in the traditional basketball cycle. A physical activity enjoyment Scale revealed that in girls, the level of enjoyment increased significantly (Δ% = + 0.27; P < 0.001) after an adapted basketball cycle. There was no significant change in physical enjoyment in boys EG (P = 0.808) and participants in the control groups. These results push us to opt more for adapted and motivational learning situations to make the teaching-learning process better, in students with overweight.

A Basketball Big Data Platform for Box Score and Play-by-Play Data.

This is the second part of a research diptych devoted to improving basketball data management in Spain. The Spanish ACB (Association of Basketball Clubs, acronym in Spanish) is the top European national competition. It attracts most of the best foreign players outside the NBA (National Basketball Association, in North America) and also accelerates the development of Spanish players who ultimately contribute to the success of the Spanish national team. However, this sporting excellence is not reciprocated by an advanced treatment of the data generated by teams and players, the so-called statistics. On the contrary, their use is still very rudimentary. An earlier article published in this journal in 2020 introduced the first open web application for interactive visualization of the box score data from three European competitions, including the ACB. Box score data refer to the data provided once the game is finished. Following the same inspiration, this new research aims to present the work carried out with more advanced data, namely, play-by-play data, which are provided as the game runs. This type of data allow us to gain greater insight into basketball performance, providing information that cannot be revealed with box score data. A new dashboard is developed to analyze play-by-play data from a number of different and novel perspectives. Furthermore, a comprehensive data platform encompassing the visualization of the ACB box score and play-by-play data is presented.

How does classification score affect falls in wheelchair basketball? A video-based cross-sectional study on the Italian national team during the European Para Championships 2023.

OBJECTIVES: The aim of this study was to investigate the mechanism of falls in male elite wheelchair basketball (WB) players and to analyse the falls characteristics considering their classification score which ranges from 1.0 to 4.5 and it is related to their functional capacity and particularly to their volume of action. DESIGN: A cross-sectional video analysis was conducted using European para championships 2023official match videos. SETTING: Players of the sample team were divided into 2 groups according to their classification point: low-point players (LPP) and high-point players (HPP). Every occurred fall was systematically analysed focusing on falling related characteristics and game circumstances. PARTICIPANTS: Twelve WB players of the Italian national team. MAIN OUTCOME: Number of falls and mechanism of falls. RESULTS: The results showed a higher number of falls for HPP and highlighted a statistically significant differences between LPP and HPP for the fall direction, the playing time and the first anatomical site in contact with the floor. CONCLUSION: Results reported significant differences between LPP and HPP in terms of mechanism of fall. Further studies should focus on the development of new preventive training strategies tailored to WB players with different levels of impairments to reduce fall related injuries.

Effects of mini-basketball training program on social communication impairments and regional homogeneity of brain functions in preschool children with autism spectrum disorder.

BACKGROUND: Social communication impairments (SCI) is a core symptom of autism spectrum disorder (ASD) and is marked by challenges in social interaction. Although physical exercise has been shown to improve SCI, this finding has not been supported by comprehensive scientific evidence. Existing research has established a strong link between the SCI in children with ASD and abnormalities in regional homogeneity (ReHo). Therefore, investigating the effects of physical exercise on SCI and Reho in patients with ASD may help to elucidate the neurological mechanisms involved. METHODS: The present study included 30 preschool children diagnosed with ASD, with 15 participants in each group (experimental and control). The experimental group underwent a 12-week mini-basketball training program (MBTP) based on routine behavioral rehabilitation, while the control group only received routine behavioral rehabilitation. The Social Responsiveness Scale-Second Edition (SRS-2) was employed to assess SCI in both groups. Resting-state functional magnetic resonance imaging technology was used to evaluate ReHo in both groups. RESULTS: After 12-week of MBTP, significant group × time interactions were observed between the experimental and control groups in total SRS-2 scores (F = 14.514, p < 0.001, ηp2 = 0.341), as well as in the domains of social cognition (F = 15.620, p < 0.001, ηp2 = 0.358), social communication (F = 12.460, p < 0.01, ηp2 = 0.308), and autistic mannerisms (F = 9.970, p < 0.01, ηp2 = 0.263). No statistical difference was found in the scores for the social awareness subscale and social motivation subscale in the group × time interaction (all p > 0.05). The experimental group exhibited increased ReHo in the right Cerebellum_Crus1 and right parahippocampal gyrus, coupled with decreased ReHo in the left middle frontal gyrus (orbital part), left superior frontal gyrus (dorsolateral), left postcentral gyrus, and right superior parietal gyrus. Furthermore, a decrease in ReHo in the left postcentral gyrus positively correlated with changes in social communication scores in SCI behaviors (p < 0.05). CONCLUSIONS: Our study underscores the effectiveness of a 12-week MBTP in ameliorating SCI and abnormalities in ReHo among preschool children with ASD. TRIAL REGISTRATION: The trial is retrospectively registered on the Chinese Clinical Trial Registry (ChiCTR1900024973; August 5, 2019).

Examining the Role of Fan Support on Home Advantage and Home Win Percentage in Professional Women's Basketball.

Our main aim in this study was to analyze any differences in Win Percentages at Home (HW) that might represent a Home-Court Advantage (HA) in women's professional basketball. A secondary objective was to analyze how team ability might modify the HA effect by comparing any interaction effect between HW and team ability in games played with and without fans. We collected data from first Spanish female basketball divisions, using a linear mixed model (LMM) for repeated measures to identify differences between time periods (games with fans vs. games without fans) for HA and HW. When comparing games with and without fans, we found no significant HA and HW differences (p = .283 and p = .872, respectively). In fact, interestingly, we observed higher win values when fans were absent. Additionally, during the COVID-19 shut down stage, HA increased; but it returned to pre-pandemic levels afterward, with no significant differences between these periods (p = .482). Similarly, while HW seemed to increase during the COVID-19 shut down period and continued improving in the post-pandemic phase, there were actually no statistically significant differences (p = .772). Higher HA and HW were evident without fans during the pandemic compared to the pre-pandemic period when fans were present in women's professional basketball. During the post-pandemic period, HA decreased upon fans' return, while HW continued increasing. We discuss possible bases for these unexpected findings.

The procedure presented was developed with the objective of determining indicators for the evaluation of the initial phase of the basketball free throw, in the 9-10-year-old category. In its preparation, the low percentages of effectiveness in both attempted and scored were taken into account, as well as the deficiencies in execution obtained in the preliminary study, carried out on 120 children from the western zone, with a mastery of only 25% of the biomechanical aspects to be achieved in the teaching process; this constituted one of the main motivations for the preparation of the evaluation procedure. The documentary analysis, observation through structured guides and videography techniques, as well as the interview, made it possible to detect insufficiencies in the evaluation of the execution of the free throw in sports initiation. In the work, the assessment was carried out, through the criteria of specialists and the criteria of users, and leaves open a space to expand actions of a methodological order and of a scientific, technical, physiological, theoretical and psychological nature that serve the development of teachers and coaches. base.

Multimodal audio-visual robot fusing 3D CNN and CRNN for player behavior recognition and prediction in basketball matches.

Introduction: Intelligent robots play a crucial role in enhancing efficiency, reducing costs, and improving safety in the logistics industry. However, traditional path planning methods often struggle to adapt to dynamic environments, leading to issues such as collisions and conflicts. This study aims to address the challenges of path planning and control for logistics robots in complex environments. Methods: The proposed method integrates information from different perception modalities to achieve more accurate path planning and obstacle avoidance control, thereby enhancing the autonomy and reliability of logistics robots. Firstly, a 3D convolutional neural network (CNN) is employed to learn the feature representation of objects in the environment for object recognition. Next, long short-term memory (LSTM) is used to model spatio-temporal features and predict the behavior and trajectory of dynamic obstacles. This enables the robot to accurately predict the future position of obstacles in complex environments, reducing collision risks. Finally, the Dijkstra algorithm is applied for path planning and control decisions to ensure the robot selects the optimal path in various scenarios. Results: Experimental results demonstrate the effectiveness of the proposed method in terms of path planning accuracy and obstacle avoidance performance. The method outperforms traditional approaches, showing significant improvements in both aspects. Discussion: The intelligent path planning and control scheme presented in this paper enhances the practicality of logistics robots in complex environments, thereby promoting efficiency and safety in the logistics industry.

Effects of small-sided games training programs on physiological and physical adaptations of youth basketball players: A systematic review.

The primary objective of this study was to systematically investigate the physiological and physical fitness adaptations resulting from small-sided games (SSGs) training programs in basketball players competing at youth competitive levels, as compared to other training approaches and/or control groups. To achieve this, we conducted a literature search on PubMed, Scopus, SPORTDiscus, and Web of Science, adhering to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. From the initial 626 studies retrieved, five were considered eligible for the current study. Among the five included articles, four conducted comparisons between the effects of SSGs and running-based high-intensity interval training. Regarding this, the four studies revealed a significant improvement in the final velocity during the 30-15 Intermittent Fitness Test, ranging from 4.07% to 7.29% following SSG-based interventions. This improvement was not significantly different from the comparator group. Additionally, two studies indicated that the SSGs group showed a significant advantage in change-of-direction time, with improvements ranging from -2.11% to 6.69% after interventions, and these results were not significantly different from the comparator group. However, the effects on repeated sprint ability yielded contradictory findings; two studies reported significant improvements ranging from -5.00% to -2.16%, while two others did not show significant effects following SSGs-based interventions. Similarly, in the linear sprint, the results of SSGs-based interventions were inconsistent. In summary, based on the available research, it can be concluded that SSG-based training is effective in significantly enhancing aerobic performance and change of direction, comparable to alternative approaches. However, the effects on repeated sprint ability and sprint performance are not consistently demonstrated.

Composite rating method: Application to European basketball leagues.

This paper introduces the Composite Rating Method (CRM), a novel approach for the integrated evaluation of basketball player and team performances across multiple leagues. Utilizing data from Euroleague, EuroCup, and Basketball Champions League, the presented method provides comprehensive and accurate rankings, including accounting for actions not included in personal statistics. Drawing inspiration from established methodologies such as ELO, PER, Offensive and Defensive ratings, CRM offers a balanced assessment of player and team capabilities. The paper delineates the data collection and preprocessing procedures, details the algorithmic framework of CRM, and showcases its predictive capacity. By presenting a well-rounded approach to ranking, this paper aims to contribute to the advancement of performance evaluation methods in basketball and sports in general.

A Longitudinal Study of the Development of Executive Function and Calibration Accuracy.

This longitudinal study examined the development of executive function and calibration accuracy in preadolescents. This study's sample consisted of 262 students (127 females) from grades 4 (n = 91), 5 (n = 89), and 6 (n = 82) who took measures of executive function and performance calibration in a sport task three times over 20 months. A latent growth-curve modeling analysis showed a significant relationship between the rates of change of executive function and calibration accuracy. The results also showed a dynamic interplay in the development of executive function and calibration accuracy. There were significant interindividual differences in the estimated population means both in executive function and calibration accuracy and in the rate of change of executive function, but not in the rate of change of calibration accuracy. The age of the participants had a positive effect only on the estimated population mean of executive function.

Prediction of fat-free mass from body surface area in young basketball players.

BACKGROUND: Fat Free Mass (FFM) is an important and essential indicator in various sports populations, since greater muscle and bone mass generates greater strength, endurance and speed in athletes. OBJECTIVE: The purpose of the study was to validate Body Surface Area (BSA) as an anthropometric indicator to estimate FFM in young basketball players. METHODS: A descriptive cross-sectional study was carried out in 105 male basketball players of the Brazilian Basketball Confederation of Sao Paulo (Campinas), Brazil. The age range was 11 to 15 years. Weight and height were evaluated. BSA, body mass index (BMI) and maturity status (MS) were calculated. Total body scanning was performed by dual X-ray absorptiometry (DXA). The components were extracted: Fat mass (FM), Fat free mass (FFM), percentage of fat mass (%FM) and bone mass (BM). The data were analyzed using the correlation coefficient of concordance (CCC) in terms of precision and accuracy. RESULTS: Three regression equations were generated: equation 1 had age and body weight as predictors [FFM= -30.059+(2.926*age)+(0.625*Weight)] (R2 = 92%, precision = 0.96 and accuracy = 0.99), equation 2 used age and BSA [FFM=-45.719+(1.934*age)+(39.388*BSA)] (R2 = 94%, precision = 0.97 and accuracy = 0.99) and equation 3 was based on APHV and BSA [FFM=-15.284+(1.765*APHV)+(37.610*(BSA)] (R2 = 94%, precision = 0.96 and accuracy = 0.99). CONCLUSIONS: The results suggest the use of anthropometric equation using decimal age and BSA to estimate FFM in young basketball players. This new method developed can be used to design, evaluate and control training programs and monitor the weight status of athletes.

Warm-up is an efficient strategy to prevent diurnal variation of short-term maximal performance in young basketball players.

The objectives of this study were to investigate: 1) whether there were morning-to-evening differences in short-term maximal performance and 2) the impact of prolonged and specific warm-up on short-term maximal performance diurnal variations in young basketball players. Fifteen basketball players of both sexes (Male = 8; Female = 7; age: 14.4 ± 0.46 yr; weight: 64.7 ± 7.1 kg; height: 175.2 ± 6.6 cm; BMI: 21.1 ± 1.9 kg/m2) completed the following short-term maximal performance tests: CMJ with and without arm swing, Lane Agility Drill, Zig-Zag agility test with and without the ball, Sprint 20 m with and without the ball with the passage at 5 and 10 m. All tests were performed after the 15-min standard warm-up procedure (with static stretching) and/or 25-min specific warm-up (with prolonged running and dynamic stretching) in the morning and evening. Vertical jumping tests and all change-of-direction speed tests (with and without a ball) with superior responses were achieved in the evening after standard warm-up among all participants (p < 0.05). In contrast, superior short-term maximal performance was observed in the morning after prolonged and specific warm-up protocol (p < 0.05). It was concluded that specific and prolonged warm-up protocols are suitable strategy to prevent diurnal variation in short-term maximal performance in young basketball players.

Biomechanical Factors Predisposing to Knee Injuries in Junior Female Basketball Players.

This cross-sectional observational study aims to determine isokinetic normality data at different speeds, and isometric data of ankle and knee joints, in healthy basketball players aged 15-16 years old. The participants were recruited through non-probabilistic convenience sampling. Sociodemographic, anthropometric, and biomechanical variables were collected. The study involved 42 participants. Right-leg dominance was higher in women (85.7%) than in men (78.6%). Men had a higher weight, height, and body mass index compared to women. Statistically significant differences were observed between sex and height (p < 0.001). Significant differences were found between sexes in knee flexor and extensor strength at different isokinetic speeds (30°, 120°, and 180°/s), except for the maximum peak strength knee flexion at 180°/s in the right leg. In the ankle, the variables inversion, eversion, and work strength values at different isokinetic speeds and full RoM, by sex, were not significantly different, except for the right (p = 0.004) and the left (p = 0.035) ankle full RoM. The study found lower knee extensor strength in women, indicating the need to improve knee flexor/extensor strength in women to match that of men, as seen in other joints. The results can guide the development of preventive and therapeutic interventions for lower limb injuries in basketball players.

The power of human touch: Physical contact improves performance in basketball free throws.

How pervasive is the power of human touch? Physical touch by other humans shows social support and alleviates stress - stress that may otherwise interfere with performance in athletic tasks. We argue that physical touch improves performance in highly stressful situations: free throws in basketball. In two studies (Ntotal = 60 NCAAW games, ktotal = 835 free throw tandems), we assessed how often teammates touched the shooting player (e.g., a tap on the shoulder) in between shooting two free throws. We find that the extent of touch (i.e., being touched by 0, 1, 2, 3, or all 4 teammates) after the first free throw predicted success with the second free throw, but only when players missed the first free throw (integrated data analysis: main effect hand taps: b = 0.47, p = .021; main effect first free throw: b = 1.36, p = .019; interaction effect: b = -0.55, p = .024). We argue that this means that teammates' support expressed in physical touch helps particularly when stress levels are already high. Results are robust when controlling for players' skill level, home versus away games, point difference, and remaining playing time. More frequent touch was also tendentially associated with teams' season success (ACC-teams only, main effect of hand taps: b = -0.42, p = .062). Physical touch thus indeed boosts performance under stress, superseding a range of other factors, likely also in other team sports and interpersonal relationships.

Empowering motivation: the journey of wheelchair basketball athletes to overcome constraints.

Introduction: The aim of this phenomenological study is to determine the motivational factors in the participation of wheelchair basketball players in sports according to Self-Determination Theory. Methods: The study group of the research was determined by the criterion sampling method, which is one of the purposeful sampling methods. Accordingly, thirteen (13) wheelchair athletes constituted the study group. In the research, a personal information form and a semi-structured interview form were prepared as data collection tools within the framework of the self-determination theory. Interviews were conducted face-to-face with the prepared interview forms. The data were analyzed by reflexive thematic analysis method. Results: Six (6) themes emerged: constraints, coping strategies, appreciation, positive feedback, need for existence, and development. Sixteen sub-themes related to these themes were identified. Conclusion: The most significant factors causing a lack of motivation in wheelchair basketball athletes were observed to be structural constraints such as access to materials and facilities. Extrinsic sources of motivation were identified as the positive attitudes and behaviors of individuals in their environment, often related to admiration, appreciation, and being set as an example, and this situation has a positive impact on wheelchair basketball athletes. On the other hand, it can be stated that intrinsic motivations such as identity change, gaining self-confidence, and the feeling of success are crucial in overcoming constraints through sports participation.

Multivariate Analysis of Risk Factors for Injury and Surgical Interventions in Ankle and Knee Injuries in NBA Athletes.

Objective: Lower extremity ankle and knee injuries occur at a high rate in the National Basketball Association (NBA) often requiring surgical intervention. This study aimed to identify surgical rates and risk factors for surgical intervention using multivariate analysis in ankle and knee injuries in NBA player. Methods: Player demographics, performance metrics, advanced statistics, and injury characteristics were recorded using publicly available data. To standardize injury events over multiple years, injury events per 1000 athlete exposure events (AE, one player participating in one game) were calculated. Descriptive analysis and multivariate logistic regression were completed to find associations with surgical intervention in ankle and knee injuries. Results: A total of 1153 ankle and knee injuries were included in the analysis with 73 (6.33%) lower extremity injuries treated with surgery. Knee injuries had a higher incidence of surgical intervention (0.23 AE) than ankle injuries (0.04 AE). The most frequent surgical knee injury was meniscus tear treated with meniscus repair (0.05 AE) and the most frequent ankle surgery was surgical debridement (0.01 AE) Multivariate logistic regression indicated lower extremity injuries that required surgery were associated with more minutes per game played (odds ratio [OR] 1.13; p = 0.02), a greater usage rate (OR 1.02 p < 0.001), the center position (OR 1.64; 95% [CI] 1.2-2.24; p = 0.002) and lower player efficiency rating (OR 0.96; 95% p < 0.001). Conclusion: Knee surgery was significantly more frequent than ankle surgery despite similar injury rates per 1000 exposures. The center position had the greatest risk for lower extremity injury followed by minutes played while a higher player efficiency rating was protective against surgical intervention. Developing strategies to address these factors will help in the management and prevention of lower extremity injuries requiring surgical intervention.

Conocimiento y prevalencia de síntomas de disfunciones del suelo pélvico en mujeres nulíparas que practican deportes de alto impacto: estudio preliminar / Knowledge and prevalence of symptoms of pelvic floor dysfunctions in nulliparous women who practice high impact sports: Preliminary study

Objetivos Describir los conocimientos sobre el suelo pélvico (SP), las disfunciones del suelo pélvico (DSP), sus principales factores de riesgo y las estrategias preventivas y de tratamiento para las mismas, así como determinar la prevalencia de síntomas de DSP y el distrés que producen en mujeres nulíparas que practiquen baloncesto, fútbol o balonmano. Metodología Estudio descriptivo transversal, de base poblacional. Se incluyeron mujeres mayores de edad que practicasen baloncesto, fútbol o balonmano al menos tres horas semanales durante dos años. Se excluyeron mujeres embarazadas, con antecedentes gestacionales, con alteraciones cognitivas o visuales. Para llevar a cabo el estudio, se diseñó un cuestionario ad hoc en la plataforma de Google Forms, que se difundió mediante WhatsApp. Resultados Las participantes tenían mayor conocimiento sobre la incontinencia urinaria (10/12 puntos) que sobre los prolapsos de órganos pélvicos (6/12 puntos). A pesar de tener conocimientos sobre la localización del SP y sus funciones, no realizaban una contracción anticipada de esta musculatura antes de levantar peso. Se obtuvo una prevalencia de síntomas de DSP del 84,6%, destacando la incontinencia urinaria (82,9%). El distrés producido por estos síntomas fue leve (mediana: 11,97; RIC: 16,7). Conclusiones Las mujeres de la muestra tienen conocimientos elevados sobre el SP y las DSP; sin embargo, no utilizan la contracción anticipada de la musculatura del SP como estrategia de protección frente al incremento de presión intraabdominal durante la práctica deportiva. La prevalencia de síntomas de DSP es alta, aunque el distrés que estos síntomas les producen es leve. (AU)

Objectives To describe the knowledge about the pelvic floor (PF), pelvic floor dysfunctions (PFD), its main risk factors, and the preventive and treatment strategies for them, as well as to determine the prevalence of PFD symptoms and the distress produced in nulliparous women who play basketball, football or handball. Methodology Descriptive cross-sectional study, population-based. Women of legal age who practiced basketball, football or handball for at least 3hours a week for 2years were included. Pregnant women, with a history of pregnancy, with cognitive or visual alterations were excluded. To carry out the study, an ad hoc questionnaire was designed on the Google Forms platform, which was disseminated through WhatsApp. Results The participants had greater knowledge about urinary incontinence (10/12 points) than about pelvic organ prolapse (6/12 points). Despite having knowledge about the location of the PF and its functions, they did not perform an anticipated contraction of this muscle before lifting weights. A prevalence of PFD symptoms of 84.6% was obtained, highlighting urinary incontinence (82.9%). The distress produced by these symptoms was mild (median: 11.97; IQR: 16.7). Conclusions The women in the sample have high knowledge about the PF and the PFD, however, they do not use the anticipated contraction of the PF muscles as a protection strategy against the increase in intra-abdominal pressure during sports practice. The prevalence of PFD symptoms is high, although the distress that these symptoms cause them is mild. (AU)

Introducción: En varios de los deportes la composicióncorporal (CC) es una característica importante que se evalúaperiódicamente en los atletas, al ser considerada un indicadorimportante de la condición física. Objetivo: Identificar los índices antropométricos que permiten predecir la masa libre de grasa (MLG) en seleccionados universitarios de basquetbol 3x3 pertenecientes a Federación Internacional del Deporte Universitario (FISU). Metodología: Se diseñó un estudio descriptivo transversal en jóvenes basquetbolistas de 5 selecciones universitarias pertenecientes a la FISU (Argentina, Brasil, Chile, Colombia, Costa Rica, El Salvador, México y Perú). Participaron de formavoluntaria 46 basquetbolista (24 hombres y 22 mujeres) conun rango de edad de 18 a 23 años. Se evaluó el peso, la es-tatura y la MLG por biompedancia eléctrica. Se calculó el índice de masa corporal (IMC), índice tri-ponderal (IPT), y elárea de superficie corporal (ASC). Resultados: El promedio de edad de los hombres fue21.1±1.9 años y de mujeres 21.3±2.0 años. El poder de ex-plicación entre MLG con el ASC en ambos sexos fueron elevados (hombres R2= 79%, y en mujeres 80<%). El IMC y elITP mostraron valores inferiores que oscilaron desde R2=0.07 hasta R2= 36%). Lolos mejores ajustes del RMSE fueronpara el ASC y en ambos sexos (RMSE= 3,2 hasta 4,3). Conclusión: Los resultados del estudio han evidenciado que el ASC es el mejor predictor de la MLG en relación al IMCe ITP. Estos hallazgos sugieren el uso del ASC para estimar la MLG en jóvenes basquetbolistas 3x3 de ambos sexos.(AU)

Introduction: In several sports, body composition (BC) isan important characteristic that is periodically evaluated inathletes, as it is considered an important indicator of physicalcondition.Objective: To identify the anthropometric indices thatallow predicting fat-free mass (FFM) in selected university 3x3basketball players belonging to the International University Sports Federation (FISU). Methodology: A descriptive cross-sectional study was de-signed in young basketball players from 5 university teamsbelonging to FISU (Argentina, Brazil, Chile, Colombia, Costa Rica, El Salvador, Mexico and Peru). Forty-six basketball pla-yers (24 males and 22 females) with an age range of 18 to 23 years participated voluntarily. Weight, height and FFM wereevaluated by electrical bioimpedance. Body mass index (BMI),tri-ponderal index (TPI), and body surface area (BSA) werecalculated. Results: The mean age of males was 21.1±1.9 years andof females 21.3±2.0 years. The explanatory power betweenFFM with BSA in both sexes were high (males R2= 79%, andin women 80<%). BMI and TPI showed lower values rangingfrom R2= 0.07 to R2= 36%). The best fits of the RMSE werefor BSA and in both sexes (RMSE= 3.2 to 4.3). Conclusion: The results of the study have shown that ASCis the best predictor of FFM in relation to BMI and TPI. Thesefindings suggest the use of BSA to estimate the FFM in young3x3 basketball players of both sexes.(AU)

The effectiveness of the STOP-X training program on the knee valgus angle and balance in female basketball players with dynamic knee valgus: a randomized controlled trial.

BACKGROUND: Dynamic knee valgus (DKV) accompanied by poor balance is the cause of anterior cruciate ligament (ACL) injury in athletes, and the identification and correction of these factors are always of interest to researchers. Therefore, the purpose of this research was to investigate the effect of the STOP-X program on the knee valgus angle and static and dynamic balance in female basketball players with DKV defects. METHODS: The present study was a quasi-experimental study. Thirty female basketball players with DKV defects were purposefully identified by the single-leg landing (SLL) test and were randomly assigned to two control (n = 15) and experimental (n = 15) groups. Static balance status was evaluated with the BASS STICK test, and dynamic balance status was evaluated with the Y-balance test (YBT). The experimental group performed the STOP-X program for 25-40 min for eight weeks (three times per week), and the control group performed their traditional warm-up program. Data were analyzed by means of 2 × 2 repeated measures ANOVA followed by post hoc comparison (Bonferroni) at the significance level of (P < 0.05) with SPSS version 26. RESULTS: The results showed that with the use of the STOP-X program, there was a significant difference between the experimental and control groups in variables of the static balance (F = 56.45; P = 0.001; ES = 0.66, PC=↑59.64%), total dynamic balance score (F = 107.57; P = 0.001; ES=↑0.79, PC=↑19.84%), and knee valgus angle (F = 119.46; P = 0.001; ES = 0.81, PC=↓34.36%). CONCLUSION: In addition to reducing the knee valgus angle, applying the STOP-X injury prevention program can improve static and dynamic balance in female basketball players with DKV defects. Therefore, it can be recommended that sports trainers benefit from these advantages by adding STOP-X training to routine basketball exercises.
