To characterize the physical and physiological responses during different basketball practice drills and games.
Male basketball players (n=11; 19.1+/-2.1 y, 1.91+/-0.09 m, 87.9+/-15.1 kg; mean+/-SD) completed offensive and defensive practice drills, half court 5on5 scrimmage play, and competitive games. Heart rate, VO2, and triaxial accelerometer data (physical demand) were normalized for individual participation time. Data were log-transformed and differences between drills and games standardized for interpretation of magnitudes and reported with the effect size (ES) statistic.
There was no substantial difference in the physical or physiological variables between offensive and defensive drills; physical load (9.5%; 90% confidence limits+/-45); mean heart rate (-2.4%; +/-4.2); peak heart rate (-0.9%; +/-3.4); and VO2 (-5.7%; +/-9.1). Physical load was moderately greater in game play compared with a 5on5 scrimmage (85.2%; +/-40.5); with a higher mean heart rate (12.4%; +/-5.4). The oxygen demand for live play was substantially larger than 5on5 (30.6%; +/-15.6).
Defensive and offensive drills during basketball practice have similar physiological responses and physical demand. Live play is substantially more demanding than a 5on5 scrimmage in both physical and physiological attributes. Accelerometers and predicted oxygen cost from heart rate monitoring systems are useful for differentiating the practice and competition demands of basketball.
描述不同篮球练习和比赛中的身体和生理反应。
男性篮球运动员(n=11;19.1+/-2.1 岁,1.91+/-0.09 米,87.9+/-15.1 千克;平均值+/-标准差)完成了进攻和防守练习、半场 5 对 5 混战和竞技比赛。心率、VO2 和三轴加速度计数据(身体需求)按个人参与时间进行归一化。数据进行对数转换,并对训练和比赛之间的差异进行标准化,以便解释幅度,并使用效应大小(ES)统计量报告。
进攻和防守练习之间的身体或生理变量没有实质性差异;身体负荷(9.5%;90%置信限+/-45%);平均心率(-2.4%; +/-4.2%);最大心率(-0.9%; +/-3.4%)和 VO2(-5.7%; +/-9.1%)。与 5 对 5 混战相比,比赛中的身体负荷略高(85.2%; +/-40.5%),平均心率更高(12.4%; +/-5.4%)。实际比赛的耗氧量明显大于 5 对 5(30.6%; +/-15.6%)。
篮球练习中的进攻和防守练习具有相似的生理反应和身体需求。与 5 对 5 混战相比,实际比赛在身体和生理属性方面的要求都要高得多。加速度计和基于心率监测系统预测的耗氧量对于区分篮球的练习和比赛需求非常有用。
