摘　　要：目的:旨在对男子轮椅竞速T53/54级1 500 m比赛距离的供能特征进行研究。方法:招募了8名男子T53/54级轮椅竞速运动员(年龄24±5岁,身高174.4±5.9 cm,体重67.3±9.1 kg)在室外400 m田径场分别进行多级递增负荷测试和1 500 m模拟比赛测试,测试全程使用气体代谢仪记录每次呼吸的V O2,使用GPSports和心率带对受试者每秒速度和心率变化进行监控,运用最大累积氧亏法对模拟比赛过程中的能量供应进行计算。结果:受试者模拟比赛中,累积氧亏、峰值心率和净累积血乳酸分别为2 667.3±894.5 m L、188.9±9.0次/min和7.5±2.8 mmol/L。1 500 m全力运动下总供应量为205.5±29.2 k J,有氧和无氧供能量为146.6±21.6 k J(71.7%±7.1%)和58.9±18.9 k J(28.3%±7.1%)。运动员测试时间和净累积血乳酸具有边缘性显著负相关(P=0.057,r=-0.798)。结论:男子轮椅竞速T53/54级1 500 m是有氧供能为主导的比赛项目,目前对这一比赛距离供能特征的认识低估了有氧供能的重要性。Objective： The aims of this study is to investigate the energy contribution of T53/54 men＇s wheelchair racing 1 500 m. Methods：Eight T53/54 men＇s wheelchair racers（24±5 years, 174.4±5.9 cm,67.3±9.1 kg） participated in the research for a graded exercise test and a 1500 m all-out test. A portable gas analyzer was used to measure V O2 at every breath, and a GPSports and Polar heart rate（HR） belt was used to monitor speed and HR changes. The energetic contribution was measured with the maximal accumulated oxygen deficit（MAOD）. Result： The subjects＇ AOD, HRmax, and BLCnet were2 667.3±894.5 ml, 188.9±9.0 bpm, and 7.5±2.8 m M, respectively. The total energy contribution of the1 500 m test was 205.5±29.2 k J. The aerobic and anaerobic energy contributions were 146.6±21.6 k J（71.7±7.1%） and 58.9±18.9 k J（28.3±7.1%）, respectively. Significant marginal negative correlations were noted between race performance and BLCnet for the T53/54 men＇s 1 500 m test（P=0.057, R=-0.798）. Conclusion：T53/54 men＇s wheelchair racing 1 500 m is an aerobic-dominated event. The knowledge of energy supply in this event underestimates the importance of aerobic contribution.
