The aim of this study was to assess physiological demands of competitive basketball by measuring oxygen consumption (VO2) and other variables during practice games. Each of 12 players (20.4 +/- 1.1 years) was monitored in a 20-min practice game, which was conducted in the same way as actual games with the presence of referees and coaches. VO2 was measured by a portable system during the game and blood lactate concentration (LA) was measured in brief breaks. Subjects were also videotaped for time-motion analysis. Female and male players demonstrated respective VO2 of 33.4 +/- 4.0 and 36.9 +/- 2.6 mL/kg/min and LA of 3.2 +/- 0.9 and 4.2 +/- 1.3 mmol/L in the practice games (P>0.05). They spent 34.1% of play time running and jumping, 56.8% walking, and 9.0% standing. Pre-obtained VO(2max) was correlated to VO(2) during play (r=0.673) and to percent of duration for running and jumping (r=0.935 and 0.962 for females and males, respectively). This study demonstrated a greater oxygen uptake for competitive basketball than that estimated based on a previous compendium. The correlation between aerobic capacity and activity level suggests the potential benefit of aerobic conditioning in basketball.
本研究旨在通过测量氧耗量（VO2）和实践比赛期间的其他变量来评估竞技篮球的生理需求。对 12 名球员（20.4 +/- 1.1 岁）进行了 20 分钟的实践比赛监测，该比赛与实际比赛相同，有裁判和教练在场。比赛期间通过便携式系统测量 VO2，短暂休息时测量血乳酸浓度（LA）。还对受试者进行了时间运动分析的录像。女性和男性运动员在实践比赛中分别表现出 33.4 +/- 4.0 和 36.9 +/- 2.6 mL/kg/min 的 VO2 和 3.2 +/- 0.9 和 4.2 +/- 1.3 mmol/L 的 LA（P>0.05）。他们在比赛中 34.1%的时间在跑动和跳跃，56.8%的时间在行走，9.0%的时间在站立。预先获得的 VO（2max）与比赛中的 VO（2）相关（r=0.673），与跑动和跳跃的持续时间百分比相关（女性和男性分别为 r=0.935 和 0.962）。本研究表明，竞技篮球的耗氧量大于以前的综合研究估计的耗氧量。有氧能力与活动水平之间的相关性表明，有氧训练对篮球有潜在的益处。
