课次主观疲劳度(Session Rating of Perceived Exertion，sRPE)是一种通过评价运动过程中的感知努力/疲劳程度来量化运动负荷的方法。尽管评分者一致信度不佳，但sRPE重测信度较高。sRPE在不同运动项目、性别、年龄中都有高的效度。采集方式、训练分组的数量、咖啡因、环境温度、触觉、脑力疲劳和昼夜节律对sRPE都存在影响。建议在横向和纵向使用中，采用Category Ratio 10(CR 10)量表，固定运动后5～30 min内的某个时间采集运动员的主观疲劳度，并将准备活动、主课训练和整理活动全部纳入运动持续时间。对不能控制但存在影响的因素进行详细记录，并在后期分析过程中进行参考。未来研究将进一步发挥sRPE在损伤预防和表现提升中的价值。
Reliability and Validity of Session Rating of Perceived Exertion and Methodological Influencing Factors
Session rating of perceived exertion ( sRPE) is a method to quantify training load by evaluating perceived exertion/fa-tigue during exercise. Despite the poor scorer reliability, the retest reliability of sRPE is high. SRPE has high validity in different sports, gender and age. Collection method, number of training groups, caffeine, ambient temperature, tactile sensation, mental fatigue and circadian rhythm all have effects on sRPE. It is suggested to use CR10 scale in horizontal and vertical use, collect RPE of athletes within 5-30min after exercise, and include all preparation activities, main course training and finishing activities into the exercise du-ration. The factors, which cannot be controlled but have an impact, should be recorded in detail and referred to in the later analysis process. Future studies could further explore the value of sRPE in injury prevention and performance improvement.
