| 摘 要： | 糖是体内最主要最能快速动员的供能物质，赛前（运动前）和赛中（运动中）及时补充糖类对保持运动能力具有重要意义。一般使用糖原负荷的方法提高糖原储备的长期补糖。赛前补糖的目的主要是优化肌肉和肝脏糖原储备，维持运动时血糖稳定，保障60 min内快速运动能力和长时间末期的冲刺力；赛中补糖可显著改善糖代谢环境，提高机体运动能力，运动时间长于1 h的运动项目应在补充的液体中加人适量的糖和电解质。对于冰球等高强度、间歇性运动项目进行赛前和赛中补糖有利于运动员提高赛场竞技能力，对于一次性大强度或一次性的力量性运动以及高强度以无氧代谢占优势的一些专项（大于80% Vo2max的有氧代谢为主）一般不主张在比赛前专门补充糖，补糖不当反而有损其运动能力。
