Monitoring training load and perceived recovery indicators during the preseason and in-season phases in professional female basketball players.

During the basketball season, it is essential to carefully plan training and recovery activities to optimize players' performance. This study monitored training load and perceived recovery indicators in professional female basketball players across the preseason and in-season phases. Seventeen professional female basketball players (age: 19.6±3.1 years; height: 180.2±5.9 cm; playing position: 8 backcourt, 9 frontcourt) were monitored for eleven consecutive weeks. Each morning, players reported their perceived recovery using a 10-point Total Quality of Recovery (TQR) Scale. After each training session or game, players reported their perceived exertion using the CR-10 Scale, which was multiplied by the duration of the training or game to obtain the session load. Weekly load, monotony, strain, TQR<inf>AM</inf> (morning recovery) and TQR<inf>fw</inf> (recovery at the start of the following week) were calculated. Linear mixed models were performed to assess the effects of season phase (preseason; in-season), playing position (backcourt; frontcourt) and group (senior; under) on load and recovery variables. Weekly load, monotony and strain were higher in the preseason than the in-season phase (all P<0.001, ES: moderate-large). Strain was higher in senior players compared to under (P=0.045, ES: small). Regarding recovery variables, no effects were found for TQR<inf>AM</inf>, while TQR<inf>fw</inf> was higher in the preseason than in-season (P<0.001, ES: moderate) phase. Professional female basketball players experience lower internal loads but poorer perceived recovery during the in-season phase. Practitioners should carefully consider the stress of competition and the cumulative fatigue from high preseason loads during the transition from the preseason to the regular season.

Comparison of Biomotor Fitness Variables between Basketball and Volleyball Players in Ignatius Ajuru University of Education

Background: The purpose of this study is to compare the biomotor fitness variables between basketball and volleyball players in Ignatius Ajuru University of Education. This study adopted an ex post facto research design. Methodology: The population for this were all volleyball and basketball players, from which a sample size of 10 participants from each team were selected. To test for balance, a stork stand test was carried out, vertical jump test was used to test for power, an Illinois Agility Test (IAT) was used to test for agility, a 30m sprint/dash was used to assess the speed of the participants, and timed push-up test for muscular endurance. Statistical Package for Social Sciences (SPSS) version 25 was used for data analysis. Results &amp; Discussion: The findings revealed a 0.13 percent difference in power which was no statistically significant difference (p&gt;.05, p=0.987). There was 30.8 percent in balance which was statistically significant (p&lt;05, p=0.037). A 1.4 percent difference in agility was not deemed statistically significant (p&gt;.05, p=0.827). Volleyball players' performed 13.1% better in muscle endurance test, though not considered statistically significant (p&gt;.05, p=0.142). Conclusion &amp; Recommendation: Based on the findings from the study, it was evident that biomotor fitness variables among volleyball and basketball players in Ignatius Ajuru University of Education was virtually the same as the players demonstrated no significant difference in most biomotor variables such as speed, agility, power and muscular endurance. While being a jack of all trade (sports) makes one better than a master of none, in sports there is need for proper focus on a specific sports niche. Thus, coaches and trainers of volleyball and basketball players should help both category of players concentrate their efforts on a specific sport so as to achieve maximum biomotor fitness required for maximal performance in a specific sport.

The effects of plyometric training on physical fitness and skill-related performance in female basketball players: a systematic review and meta-analysis.

This study aims to analyze the effects of plyometric training (PT) on physical fitness and skill-related performance in female basketball players. Five databases, including Web of Science, Scopus, PubMed, EBSCOhost, and Google Scholar, were used to select articles published up to 20 December 2023, using a combination of keywords related to PT and female basketball players. The risk of bias and the certainty of evidence in included articles were assessed using the Cochrane risk of bias (RoB2) tool and "The Grading of Recommendations Assessment, Development, and Evaluation" (GRADE). Ten studies were included for the systematic review, and eight for the meta-analysis, totalling 246 female basketball players aged 14.5-22.5years. Most of these players were highly trained. Most of the included studies exhibited concerns regarding the risk of bias. The PT programs lasted 4-8weeks, conducted 2-3 sessions per week, with sessions lasting 20-90min and including 29-190 jumps. In the systematic review, most studies showed that PT significantly improved performance in countermovement jump (CMJ), squat jump (SJ), Sargent jump, standing long jump, lateral hop, medicine ball throw, t-Test, Illinois agility, lane agility drill, linear 20-m sprint, stable and dynamic leg balance, dribbling, passing, shooting, and various basketball-specific tests, as well as increased muscle volume and thigh cross-sectional area. However, some studies showed PT to induce no significant changes in performance during CMJ, t-Test, Illinois agility, knee extensor/flexor strength, linear sprint, and single leg balance tests. In the meta-analysis, CMJ height (ES = 0.37; p = 0.036), vertical jump (VJ) peak power (ES = 0.57; p = 0.015), VJ peak velocity (ES = 0.26; p = 0.004), and t-Test performance time (ES = 0.32; p = 0.004) were significantly improved with small effects following PT. The effect of PT on performance in female basketball players was mixed. Most studies indicated that PT could improve various measures of physical fitness and skill-related performance, but performance remained unchanged in some tests. More studies with established tests are needed to investigate the effect of PT on female basketball players in the future. https://inplasy.com/, Identifier INPLASY2023120078.

Do Elite Basketball Players Maintain Peak External Demands throughout the Entire Game?

Consideration of workload intensity and peak demands across different periods of basketball games contributes to understanding the external physical requirements of elite basketball players. Therefore, the aim of this study was to investigate the average intensity and peak demands encountered by players throughout game quarters. PlayerLoad per minute and PlayerLoad at three different time samples (30 s, 1 min, and 3 min) were used as workload metrics. A total of 14 professional elite male basketball players were monitored during 30 official games to investigate this. A linear mixed model and Cohen's d were employed to identify significant differences and quantify the effect sizes among game quarters. The results showed a significant, moderate effect in PlayerLoad per minute between Q1 vs. Q4, and a small effect between Q2 and Q3 vs. Q4. Furthermore, a small to moderate decline was observed in external peak values for PlayerLoad across game quarters. Specifically,, a significant decrease was found for the 3 min time window between Q1 and other quarters. The findings from the present study suggest that professional basketball players tend to experience fatigue or reduced physical output as the game progresses.

Development of a multi-level feature fusion model for basketball player trajectory tracking

To solve the problems of low matching degree, long tracking time, and low accuracy of multi-target tracking in the process of athlete motion trajectory tracking using deep learning technology, a new athlete motion trajectory tracking model was proposed in this study. The study first optimized the current object detection algorithm in basketball, utilized a hybrid attention mechanism to extract object features, and improved the non-maximum suppression strategy. Then, a hybrid branch network was introduced to improve the residual network and a new athlete identity recognition model was proposed. Finally, a new trajectory tracking model was designed by combining the object detection model and the athlete identity recognition model. The research results indicated that in the object detection experiment, the detection time of the proposed object detection algorithm was always below 0.4 s, and its average accuracy reached up to 0.63. In trajectory tracking testing, the final built tracking model had a multi-target tracking accuracy of up to 0.98, and its tracking overlap rate was as low as 0.02. This study has the following two contributions. Firstly, a new model of athlete trajectory tracking is proposed, which improves the accuracy and efficiency of multi-target tracking by optimizing object detection algorithm and introducing hybrid branch network. Second, the model has excellent performance in both object detection and track tracking, which can not only provide a new solution for athletes' motion trajectory tracking, but also significantly improve the effect of motion tracking.

Evaluation of Toenail Findings in Professional Athletes

Abstract Background/Aims: Professional athletes often encounter foot nail issues due to the demands of their intensive training and the conditions within their sports footwear. This study aims to assess the prevalence, characterize the types of nail conditions affecting professional athletes, and identify predisposing factors, shedding light on a critical yet frequently neglected area of sports-related health. Methods: We surveyed 120 professional athletes from football and basketball teams across three major sports clubs. Data on sociodemographic factors and nail issues were collected via a detailed questionnaire and corroborated with dermatological exams. Results: The research included 108 football players and 12 basketball players, with 13 female athletes among them. The participants had an average age of 22.87 years and an average sports career length of 6.72 years. Ingrown toenails were reported by 81 athletes (67.5%), with 35 cases involving multiple regions and 9 cases a single region. The condition was most frequently found in the first toe, present in 41 instances. A significant association was found between ingrown toenails and both age and sports activity duration (p=0.006 and p

Poster 342: Return to Sport Rates and Objective Measures after ACL Reconstruction for High Level Basketball Players

Objectives: Return to sports (RTS) decisions for high-level basketball players after an anterior cruciate ligament reconstruction (ACLR) are multifactorial. The literature focuses mainly on sports performance metrics and lacks objective rehabilitation measures. The purpose of this study was to determine objective measure differences following an ACLR between basketball players competing at the college/professional, high school, and recreational levels. Our hypothesis was that basketball players competing at the college/professional level would have superior performance with objective measures following an ACLR, compared to those competing at the high school and recreational levels. Methods: Patients were retrospectively selected based on the following inclusion criteria: ACLR with a contralateral patellar tendon graft (PTG), preoperative activity level of ≥8 on the modified Tegner activity rating scale, ≤25 years old, and reported playing basketball. Exclusions included: revisions, bilateral procedures, or were missing data needed for analysis. Patients were split based on their preoperative activity level (level 8 = recreational, level 9 = high school, level 10 = college/professional). Each patient received a mini open, contralateral PTG utilizing the same surgical methods and followed the same accelerated rehabilitation approach. Postoperative outcome measures included the difference in extension range of motion (ROM) at 2 weeks, difference in flexion ROM at 3 months, percent deficit in isokinetic quadriceps strength and single leg hop for distance at 4 months, and the manual maximum difference on the KT arthrometer at 2 months. Statistical analysis included chi-square and analysis of variance where appropriate. Results: Of the 329 patients, 69 were level 8, 224 were level 9, and 36 were level 10 with mean ages of 19.6, 16.4, and 19.1 years, respectively. The percent of males differed by group with level 8 at 78.3%, level 9 at 29.5%, and level 10 at 27.8% (p &lt; 0.001). The overall rate of return to competitive basketball for the cohort was 96.0%. The rate of return to competitive basketball was not statistically significantly different among the groups with level 10 having the highest rate (97.2%), followed by level 9 (96.4%) and then level 8 (94.2%), p = 0.659. Level 10 athletes had the lowest strength deficit with a mean of 9.3%, compared to 12.5% for level 9, and 15.6% for level 8, p=0.017. Single leg hop deficit was also different among groups with level 10 at 6.9%, level 9 at 6.2%, and level 8 at 10.4%, p &lt; 0.001. Knee ROM and stability were not statistically different among the groups. Conclusions: The rate of return to competitive basketball is the same among all high-level basketball players. Objectively, level 10 athletes had superior strength and single leg hop performance compared to recreational basketball players. Although the return to competitive basketball rate is the same among all groups, recreational basketball players tend to be weaker than college/professional players, therefore, added emphasis on this aspect of their rehabilitation would be beneficial for this population.

Sport-Specific Abdominal Wall Muscle Differences: A Comparative Study of Soccer and Basketball Players Using Ultrasonography

Aim: This study aims to compare the thickness of abdominal wall muscles—the external oblique (EO), internal oblique (IO), transversus abdominis (TrAb), rectus abdominis (RA), and inter-recti distance (IRD)—between amateur soccer and basketball players using ultrasonography. Methods: This cross-sectional study was conducted with 35 male amateur athletes, including 17 soccer players and 18 basketball players. Ultrasonographic measurements of the EO, IO, TrAb, RA muscles, and IRD were taken while the muscles were in a relaxed state for all the participants in both sides. Results: Significant differences were found in the RA muscle thickness, with basketball players showing a greater mean thickness compared to soccer players. No significant differences were observed in the TrAb, IO, and EO muscles between the two groups. The IRD showed a trend towards larger separation in basketball players, though this was not statistically significant. Conclusions: This study highlights sport-specific adaptations in the RA muscle, likely due to the distinct physical demands of basketball and soccer. The findings underscore the importance of tailored training and rehabilitation programs that consider these morphological differences to enhance performance and reduce injury risks.

Strength characteristics in faster change of direction basketball players: A comparison across cutting angles.

Change of directions (COD) involves multidirectional and complex actions, with performance influenced by multiple factors. As lower limb strength is one of the most determinant of COD performance, the present study aimed to (a) explore the differences in strength outcomes across different lower limb muscle actions between faster and slower basketball players in COD actions at different angles and (b) analyse the relationship between isometric, concentric and eccentric strength outcomes and COD performance at different cutting angles. Twenty-five basketball players (44% female) completed a battery of tests, encompassing isokinetic and isometric squat strength assessments, along with COD tests at 45°, 90° and 180°. Players were categorised as 'low-performance' and 'high-performance' groups based on execution time in COD, facilitating a comparison between performance groups. Results indicated that concentric strength showed the greatest differences between performance groups at 45° COD (effect size≥0.813; p≤0.034). Isometric and eccentric strength demonstrated a moderate-to-large relationship with 90° COD performance (Rho≥0.394; p≤0.045), and all muscle actions exhibited a large relationship with 180° COD (Rho≥0.445; p≤0.030). Moreover, the fastest players showed higher levels of concentric strength relative to eccentric strength, regardless of the cutting angle. These findings hold practical applications, suggesting that basketball coaches should train a specific kind of muscle action depending on the individual players' COD demands, focusing on improving the rapid eccentric force application while striving to reduce the eccentric/concentric ratio.

Effects of Plyometric Training Volume on Physical Performance in Youth Basketball Players.

Aztarain-Cardiel, K, Garatachea, N, and Pareja-Blanco, F. Effects of plyometric training volume on physical performance in youth basketball players. J Strength Cond Res 38(7): 1275-1279, 2024-The aim of this study was to analyze the effects of different plyometric training volumes on jumping, sprinting, and change-of-direction performances in youth basketball players. Thirty-one young male basketball players (age: 15.1 ± 1.8 years) from 4 squads belonging to an elite basketball club were randomly assigned to 1 of 3 groups: (a) low-volume (LV) plyometric training, (b) high-volume (HV) plyometric training, and (c) control group (CG). The subjects followed a plyometric training program twice a week for 6 weeks, differing in the training volume controlled through the number of jumps per session. Both experimental groups performed 8 repetitions in each set of bilateral vertical jumps with free arms, but HV completed twice the training volume of LV (98.7 vs. 49.3 jumps per session). Pretraining and Posttraining measurements included the following: (a) squat jump (SJ); (b) countermovement jump (CMJ); (c) horizontal jump (HJ); (d) straight-line sprint in 20 m (Sprint); and (e) V-Cut change-of-direction test (V-Cut). The LV and HV groups showed similar increases in vertical jump performance. The LV group significantly increased its performance in SJ, CMJ, and HJ (p < 0.001-0.05), whereas the HV group showed significant improvements only in SJ and CMJ (p < 0.001). Furthermore, neither group increased their sprint or change of direction performance. Control group did not improve in any performance variable analyzed. Therefore, the LV and HV plyometric training programs produce similar benefits on jump performance variables, but LV is more repetition-efficient than HV in young basketball players. This supports the statement that there is a nonlinear relationship between training volume and performance improvements.

Surgical Intervention of a Fibular Stress Fracture in a Male Basketball Player: A Case Report

This is a case of a 21-year-old male, African American Division I basketball player with a fibula stress fracture. The athlete initially reported pain, without distinct injury and was diagnosed with a stress fracture. After a short period of immobilization in a walking boot, this individual opted to undergo surgical intervention consisting of an intramedullary screw inserted in his left fibula. This was in consultation with the orthopedic team physician and orthopedic trauma surgeon. After a brief period of rest and continued immobilization in a walking boot, weight bearing as tolerated, the patient was able to start rehabilitation. He continued rehabilitation and progressive return to activity and was able to return to limited practice approximately 4 weeks. He played 13 min of a game in under 5 weeks (31 days). Stress fractures are not uncommon in basketball players, but a fibula stress fracture is one not often seen, and there is a paucity of data in the literature regarding this injury. A nonoperative approach to treatment of a fibula stress fracture typically yields good results but may lead to longer return than a surgical intervention. Providing athletes options for treatment may result in a quicker recovery. This case demonstrates a novel treatment option resulting in a quicker return to play.

Can artificial intelligence help improve the rehabilitation of anterior cruciate ligament injuries in basketball players?

For basketball players, a torn anterior cruciate ligament (ACL) can be devastating [1]. This injury often necessitates reconstructive surgery, followed by a grueling rehabilitation process that can sideline an athlete for months, jeopardizing their career trajectory [2]. However, a new beacon of hope is emerging on the horizon: artificial intelligence (AI). This powerful technology is not just a tool but a potential game-changer, rapidly transforming the way ACL recovery is approached. It offers the potential for faster, more personalized, and ultimately more successful outcomes for athletes eager to return to the court, inspiring a new era in sports medicine [3].

Did court dismiss swimmer's Title IX claim?

A University of Vermont swim team member filed a report with the university claiming she had recently been sexually assaulted multiple times by a member of the men's basketball team, with whom she was previously in a relationship. Two days later, an investigator told her she could (1) file a police report, (2) request a formal investigation, or (3) participate in an informal resolution. She allegedly told the student the informal resolution would “take less time.”

La aumentación con tenodesis extraarticular de la reconstrucción del ligamento cruzado anterior asociado a la técnica «all-inside» no modifica la vuelta al deporte en jugadores de baloncesto federados: estudio de cohortes comparativo

IntroductionReturn to play rates after anterior cruciate ligament (ACL) reconstruction range between 50-98% depending on sport professionality, without being modified by the addition of an extra-articular augmentation (EA). The objective of the study is to describe the rate of return to play in our cohort. The hypothesis is that the addition of EA increases that rate. Material and methodsA retrospective, descriptive and analytical study of a 130 basketball players cohort between 18 and 45 years old, whom underwent ACL reconstruction between the years 2018 and 2022, with a minimum follow-up of 18 months. Data was collected by reviewing medical records. IKDC score was registered after one year from surgery. All patients operated from 2020 received an extra-articular tenodesis. ResultsOf all patients, 72.31% returned to training, 70.77% returned to competition and 46.15% returned to the same level of performance prior to injury. The EA group (46.15%) did not increase the rate of return to competition (P=.552) nor to the same level of performance (P=.664). The mean IKDC. score was 86.83 (SD 14.85), and was not higher in the EA group (P=.418). However, its value was higher in the players who returned to training, competition and level of performance (P<.05). EA did not delay the return to play in any group (P=.282). ConclusionTo sum up, the EA does not modify the return to sport rate. Higher IKDC values predict a greater return to sport rate. in all groups. Prospective studies with larger sample size and longer follow-up time are required.

Changes in Countermovement Vertical Jump Force-Time Metrics During a Game in Professional Male Basketball Players.

Cabarkapa, D, Johnson, QR, Cabarkapa, DV, Philipp, NM, Eserhaut, DA, and Fry, AC. Changes in countermovement vertical jump force-time metrics during a game in professional male basketball players. J Strength Cond Res 38(7): 1326-1329, 2024-As technology within elite basketball advances and is more available to sporting organizations, novel approaches for assessing and addressing athletic performance during practice or competition are being continuously explored. The aim of this investigation was to examine changes in neuromuscular performance during live basketball play. Eight professional male basketball players volunteered to participate in this study. The testing procedures were conducted during a pre-tournament camp over a span of 2 days. During the first day, the athletes were familiarized with the testing procedures, and baseline measurements were obtained. Using a uni-axial force plate system sampling at 1,000 Hz, each athlete performed 3 countermovement vertical jumps (CVJ) without an arm swing before proceeding with their regular training activities. During the second day of the pre-tournament camp, the athletes repeated identical CVJ testing procedures before the start of the first quarter and post-first, second, third, and fourth quarter of a simulated 5-on-5 basketball game. Repeated-measures testing design was used to examine statistically significant differences in various force-time metrics of interest in comparison to the baseline levels (p < 0.05). Besides a trivial decrease in eccentric mean force, the findings of this study revealed no statistically significant changes in any force-time metrics of interest within both eccentric and concentric phases of the CVJ (i.e., mean and peak force and power, jump height, impulse, velocity, and contraction time). Thus, we can conclude that these variables were not sensitive to acute fatigue, suggesting that the neuromuscular performances of professional male basketball players tend to remain unchanged throughout a 5-on-5 simulated game.
