“…For reliability analyses, a repeated-measures, within-subject design was followed whereby players completed the simulation protocol on two separate occasions, with a minimum of 4 days and a maximum of 14 days between trials. While testing time was randomly allocated to players, each player was assessed at the same time of day in each trial (when completing repeated trials) to avoid any circadian variations in physical performance as documented previously in basketball players ( Gaos et al, 2023 ). For discriminant validity analyses, a cross-sectional, between-subjects design was followed whereby players were only required to complete the simulation protocol on a single occasion.…”

Activity simulation protocols offer useful applications in research and practice; however, the specificity of such protocols to basketball game-play is currently lacking. Consequently, this study aimed to develop a game-specific basketball activity simulation protocol representative of typical playing durations and assess its reliability and discriminant validity. The simulation protocol was modified from an original version (i.e., Basketball Exercise Simulation Test) to incorporate regular breaks indicative of time-outs, free-throws, and substitutions. Twelve competitive male and female adult basketball players competing in the fourth or fifth Spanish basketball division underwent repeated trials of the simulation protocol (min. 4 to max. 14 days apart) for reliability analyses. In turn, 13 competitive male (fifth division), 9 competitive female (fourth division), and 13 recreational male adult basketball players completed the simulation protocol to assess discriminant validity via comparisons between sexes (competitive players) and playing levels (males). A range of physical, technical, and perceptual-physiological variables were collected during and following the simulation protocol. Several physical and heart rate variables displayed the strongest reliability (intraclass correlation coefficient [ICC] = 0.72–0.96; coefficient of variation [CV] = 1.78–6.75%), with physical decrement, technical, blood lactate concentration, and rating of perceived exertion (RPE) variables having the weakest (ICC = 0.52–0.75; CV = 10.34–30.85%). Regarding discriminant analyses between sexes, males demonstrated significantly greater physical outputs in several variables and lower RPE compared to females (p < 0.05, moderate-to-large effects). Comparisons between playing levels revealed competitive males had significantly greater physical outputs across many variables, alongside higher mean heart rate and lower RPE than recreational males (p < 0.05, moderate-to-large effects). This study presents a novel game-specific basketball activity simulation protocol replicating actual playing durations and game configurations that might be successfully applied for both training and research purposes. Reliability statistics are provided for several variables to inform end-users on potential measurement error when implementing the simulation protocol. Discriminant validity of the simulation protocol was supported for several variables, suggesting it may hold practical utility in benchmarking or selecting players. Future research on this topic is encouraged examining wider samples of male and female basketball players at different levels as well as additional forms of validity for the protocol.

“…Effective assessment methods focus on improving strength, speed, balance, jump performance and power characteristics against the risk of injury for basketball players are essential for optimizing their performance during matches [5][6]. The importance of jumping for basketball players goes beyond just elevation and emphasizes the need for a comprehensive assessment that includes balance [7].…”

Background: Hamstring flexibility significantly influences athletic performance, particularly in dynamic actions like vertical jumps and balance. This study seeks to uncover the connection between hamstring shortness and the dynamic interplay of vertical jump height and balance in these youth basketball athletes. Material Method: The study included 84 male youth basketball players with hamstring shortness. Participants underwent assessments including hamstring flexibility, hip flexed and knee extended (HF-KE), Sit and Reach Test, popliteal angle measurement, vertical jump measurement with the Optojump device, and balance measurement with the Y balance test. Results: The findings from our study indicate a significant association between the results of the vertical jump test and both the left HF-KE (p < 0.001) and the popliteal angle (p < 0.001). Y balance was significantly correlated with the test (p=0.011). Multiple regression analysis revealed a relationship between right HF-KE and jumping performance (β= 0.363, R² = 0.213; F = 10.798, p =0.002) and between left HF-KE and jump (β= 0.523, R² = 0.472; F = 35.712, p< 0.001). Conclusion: In conclusion, our study underscores the crucial role of hamstring flexibility in vertical jump performance among youth basketball players. The significant associations found between left HF-KE and popliteal angle with vertical jump performance highlight the importance of addressing hamstring shortness in training programs aimed at enhancing jump performance. These findings emphasize the need for targeted interventions to improve hamstring flexibility, which could ultimately contribute to better athletic performance and injury prevention in this population.
