The aim of this study was to examine the effects of maximal aerobic power (V(.-)O2max peak) level on the ability to repeat sprints (calculated as performance decrement and total sprinting time) in young basketball players. Subjects were 18 junior, well-trained basketball players (age, 16.8 +/- 1.2 years; height, 181.3 +/- 5.7 cm; body mass, 73 +/- 10 kg; V(.-)O2max peak, 59.6 +/- 6.9 ml x kg(-1) x min(-1)). Match analysis and time-motion analysis of competitive basketball games was used to devise a basketball-specific repeated-sprint ability protocol consisting of ten 15-m shuttle run sprints with 30 s of passive recovery. Pre, post, and post plus 3-minute blood lactate concentrations were 2.5 +/- 0.7, 13.6 +/- 3.1, and 14.2 +/- 3.5 mmol x L(-1), respectively. The mean fatigue index (FI) value was 3.4 +/- 2.3% (range, 1.1-9.1%). No significant correlations were found between V(.-)O2max peak and either FI or total sprint time. A negative correlation (r = -0.75, p = 0.01) was found between first-sprint time and FI. The results of this study showed that V(.-)O2max peak is not a predictor of repeated-sprint ability in young basketball players. The high blood lactate concentrations found at the end of the repeated-sprint ability protocol suggest its use for building lactate tolerance in conditioned basketball players.
本研究旨在探讨最大有氧能力（V̇O₂max峰值）水平对年轻篮球运动员重复冲刺能力（以表现下降和总冲刺时间计算）的影响。受试者为18名训练有素的初中篮球运动员（年龄16.8±1.2岁；身高181.3±5.7厘米；体重73±10千克；V̇O₂max峰值59.6±6.9毫升·千克⁻¹·分钟⁻¹）。通过对篮球比赛的比赛分析和时间动作分析，设计了一种针对篮球的重复冲刺能力测试方案，包括十次15米往返跑冲刺，每次冲刺后有30秒的被动恢复时间。冲刺前、冲刺后以及冲刺后加3分钟时的血乳酸浓度分别为2.5±0.7、13.6±3.1和14.2±3.5毫摩尔·升⁻¹。平均疲劳指数（FI）值为3.4±2.3%（范围为1.1 - 9.1%）。未发现V̇O₂max峰值与FI或总冲刺时间之间存在显著相关性。首次冲刺时间与FI之间存在负相关（r = -0.75，p = 0.01）。本研究结果表明，V̇O₂max峰值不是年轻篮球运动员重复冲刺能力的预测指标。在重复冲刺能力测试方案结束时发现的高血乳酸浓度表明，该方案可用于增强有训练基础的篮球运动员的乳酸耐受性。
