Ten male national league players performed two trials of the 2-2 shuffle test per direction and were compared against their total steals throughout the season.

Anthropometric and total steals differences between fast and slow 2-2 shuffle performance were assessed with an independent t-test, percent difference (Diff %), and effect size (ES). The 2-2 shuffle test time for dominant (ICC = 0.86, CV = 8.61%) and non-dominant (ICC = 0.90, CV = 9.30%) directions met pre-determined reliability thresholds (ICC > 0.8, CV < 10%). Faster 2-2 shufflers were significantly shorter (1.91 ± 0.03 vs. 2.02 ± 0.09, Diff % -5.45, p = 0.03, ES = -1.3) in height and accrued more total steals than their slower counterparts (15.60 ± 9.24 vs. 9.00 ± 6.44, Diff % 42.31, p = 0.22, ES = -0.8).

Athletic performance was assessed using six standardized tests from the Korean Basketball League (KBL) Draft combine. Objective and subjective sleep quality were measured using actigraphy and three validated sleep questionnaires, respectively. The number of pull-ups performed significantly increased after the PBC condition (9.2 ± 4.59 vs. 11.9 ± 4.77 reps, p < 0.05), whereas no improvements were observed in other performance measures, including the maximum repetitions of the 75-kg bench press, sprint speed, vertical jump height, and agility. Subjective and objective sleep quality were not enhanced after the PBC condition. These findings suggest that a short-term (5-day) application of PBC has only a limited effect on athletic performance and no effect on sleep quality.

Total player load, peak player load, player load per minute and the work to rest ratio derived from accelerometry were measures of external player load used in the analysis. Linear mixed models with the match outcome (win/loss), expected margin vs. outcome, days between games, and player efficiency as fixed effects, and player ID as a random intercept were employed. A statistically significant (p = 0.001) 62.46 au difference in total player load was observed following a win compared to a loss. However, when considering the random effects of an individual, individual performance, team performance and scheduling as fixed effects, a non-significant (p = 0.086) difference was observed with the individual player being the most influential variable. There were no statistically significant differences in peak player load (p = 0.734), player load per minute (p = 0.281), and the work to rest ratio (p = 0.782) following a win compared to a loss.

Thirty-nine pre-juvenile basketball athletes (23 boys and 16 girls) performed the countermovement jump, the single leg countermovement jump, the single leg lateral jump, the single leg broad jump, and four shuffle tests (2 distances of 2.5 and 5 m × 2 in each direction) on separate days. Results revealed significant differences between the left and the right shuffle at distances of both 2.5 m (p < 0.05) and 5 m (p < 0.01), with inter-limb asymmetry scores ranging from 3.3 to 5.1%. There was no significant difference between the performance of the left and right legs in each single leg jump test, while the inter-limb asymmetry values ranged from 5.3 to 8.6%. Correlation analysis showed there were no correlations among the inter-limb asymmetry, shuffle asymmetry and performance, while the right single leg countermovement jump performance was significantly correlated with shuffle performance (all p < 0.001). Shuffle performance in different directions exhibited significant differences which were unrelated to inter-limb asymmetry, demonstrating the task-specific nature of asymmetry and natural variability seen in lateral movements of pre-juvenile basketball players. Practitioners are advised to use a diversified approach to assess asymmetry. These findings have implications for injury prevention and performance enhancement.","PeriodicalId":16055,"journal":{"name":"Journal of Human Kinetics","volume":"96 Spec","pages":"109-119"},"PeriodicalIF":1.9,"publicationDate":"2025-04-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12121893/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144199308","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study analysed and compared relationships between functional movement, jumping and linear speed performance using two distinct methods of measuring COD performance in female basketball players, while also distinguishing between cut-off angles. Fifty female semi-professional basketball players (age: 23.7 ± 3.81 years, body height: 175.5 ± 7.69 cm; body mass: 64.4 ± 7.88 kg) participated in the assessment, involving various performance and COD tests. COD tests were categorised for each method and angulation into \"low performance\" and \"high performance\" groups, facilitating a Bayesian comparative analysis. For the traditional method of measurement (execution time) vertical (ES ≥ 0.66; BF10 ≥ 3.50) and horizontal (ES ≥ 0.97; BF10 ≥ 44.4) variables exhibited significant differences between performance groups across all cutting angles, with faster players performing better in all tests. For the novel approach (COD Deficit) differences between performance groups were only found for horizontal variables, while these differences disappeared for vertical variables. These findings suggest the need for caution when considering the determinants of COD performance, as these relationships are directly dependent on the COD method used. Therefore, female basketball coaches are encouraged to adopt the COD Deficit for assessing this ability, as it isolates COD from other abilities.","PeriodicalId":16055,"journal":{"name":"Journal of Human Kinetics","volume":"96 Spec","pages":"37-51"},"PeriodicalIF":1.9,"publicationDate":"2025-04-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12121889/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144199323","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Using observational methodology, differences in the length and speed of offensive actions and their corresponding shooting efficiency were examined. Results revealed significant contrasts in the play tempo, with one team favoring fast, explosive plays (Golden State Warriors) and the other adopting slower, more strategic maneuvers (Chicago Bulls). Despite these differences, both teams maintained comparable shooting success rates. This suggests that the ability to adjust the play tempo according to game circumstances and opponent characteristics is critical for maximizing offensive efficiency. Moreover, the study demonstrates that variability in possession duration is strongly linked to fatigue management and the balance between anaerobic and aerobic energy systems. This finding underscores the importance of tactical flexibility, as adjusting the pace and intensity of play can be a decisive factor in modern basketball success, where shorter, quicker, and more explosive plays are increasingly prevalent. The study concludes that dynamic time-of-possession management and adaptive efforts are key to optimizing high-level competitive performance.","PeriodicalId":16055,"journal":{"name":"Journal of Human Kinetics","volume":"96 Spec","pages":"225-233"},"PeriodicalIF":1.9,"publicationDate":"2025-04-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12121881/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144199329","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The results indicated significant differences between dominant and non-dominant limbs in all tasks, with ASI values ranging from 3.02% to 27.8%. Directionality of asymmetry varied across tests. Correlation analysis revealed that greater asymmetry was associated with slower COD performance (ρ range = -0.67 to 0.57). Moreover, asymmetry in some tasks was related to lower ground reaction forces (GRFs) (ρ range = -0.60 to -0.42) and higher contact times during COD 180° (ρ = 0.45). The results of this study support the need to address inter-limb asymmetries in basketball players.

Data on kinematics, kinetics, and electromyography were collected from 24 participants, comprising 12 in the ASYM group and 12 in the CON group, performing a stop-jump task in four stages (1st, 2nd, 3rd, 4th). A musculoskeletal model was used to calculate PTF, and Orthogonal Partial Least Squares Discriminant Analysis (OPLS-DA) identified significant variables. In the first three stages, the ASYM group showed significantly greater PTF and the ankle discrete relative phase (ADRP) than the CON group, with differences of 0.98, 0.79, 0.81kg•BW-1 (p < 0.001) and 7.34°, 11.24°, and 2.49° (p < 0.05), respectively. In the last three stages, the ASYM group had a higher knee co-activation index (KCAI) than the CON group, with differences of 0.33, 0.28, and 0.25 (p < 0.05). Correlations between PTF and the ADRP and between PTF and the KCAI were the highest, at 0.58 and 0.61, respectively. The OPLS-DA model effectively distinguished between the groups, suggesting potential applications in tendon health monitoring. The findings suggest that elevated PTF may be linked to tendinopathy in male amateur basketball players, highlighting the importance of comprehensive strategies, such as improving ankle symmetry and optimizing muscle coordination to mitigate tendon load and injury risk.","PeriodicalId":16055,"journal":{"name":"Journal of Human Kinetics","volume":"96 Spec","pages":"69-81"},"PeriodicalIF":1.9,"publicationDate":"2025-04-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12121886/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144199309","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
