Abstract：
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.
摘要：
活动模拟协议在研究和实践中提供了有用的应用；然而，目前缺乏此类协议对篮球比赛的特殊性。因此,本研究旨在开发一个代表典型比赛持续时间的特定篮球活动模拟协议，并评估其可靠性和判别效度。仿真协议从原始版本(即，篮球运动模拟测试)纳入指示超时的定期休息时间，罚球,和替换。在第四或第五西班牙篮球分区中竞争的十二名男女成年篮球运动员经历了模拟协议的重复试验（最小。4到max间隔14天)进行可靠性分析。反过来,13名竞争男性（第五师），9名竞争女性（第四师），13名休闲男性成年篮球运动员完成了模拟协议，以通过比较性别（竞技运动员）和比赛水平（男性）来评估判别有效性。一系列的物理，技术,在模拟协议期间和之后收集感知生理变量。几个物理和心率变量显示出最强的可靠性（组内相关系数[ICC]=0.72-0.96；变异系数[CV]=1.78-6.75％），随着物理递减，技术,血乳酸浓度，和感知劳累(RPE)变量的评级最弱(ICC=0.52-0.75；CV=10.34-30.85%)。关于两性之间的判别分析，与女性相比，男性在几个变量中表现出显着更高的身体产出，而RPE则较低（p<0.05，中等到较大的影响）。比赛水平之间的比较显示，在许多变量中，有竞争力的男性的身体输出明显更大，与娱乐性男性相比，平均心率较高，RPE较低（p<0.05，中度至重度影响）。这项研究提出了一种新颖的针对特定游戏的篮球活动模拟协议，该协议复制了实际的比赛持续时间和游戏配置，可以成功地应用于训练和研究目的。为几个变量提供了可靠性统计信息，以便在实施仿真协议时通知最终用户潜在的测量误差。对几个变量支持仿真协议的判别有效性，这表明它在基准测试或选择球员方面可能具有实际效用。鼓励对该主题进行未来的研究，以检查不同级别的男女篮球运动员的更广泛样本以及该协议的其他有效性形式。
