研究目的：

本研究旨在构建基于真实1RM、负荷速度特征、RIR和RPE信息的卧推与平行深蹲最大力量评估与预测框架，系统比较不同信息条件下最大力量预测方法的准确性和应用价值。具体目的包括：测定卧推和平行深蹲在不同相对负荷下的平均速度、RIR和RPE特征，分析其与真实1RM的关系；评估单一亚极限负荷下重复动作速度损失对1RM预测的价值；在不依赖速度设备的条件下，基于负荷、RIR、RPE、身体形态、体成分和训练背景信息构建1RM预测模型；采用可解释机器学习方法识别影响卧推和平行深蹲最大力量水平的关键预测因子，为抗阻训练监控、训练负荷安排和个体化力量评估提供依据。  

Objectives of Study：

This study aims to develop a maximum strength assessment and prediction framework for the bench press and parallel squat based on true one-repetition maximum, load-velocity characteristics, repetitions in reserve, and rating of perceived exertion. The specific objectives are to examine mean velocity, RIR and RPE characteristics at different relative loads and their associations with true 1RM; to evaluate the predictive value of velocity loss during repeated repetitions under a single submaximal load; to develop and validate 1RM prediction models without relying on velocity-measuring devices by using load, RIR, RPE, anthropometric characteristics, body composition and training background; and to identify key predictors of maximum strength using interpretable machine learning methods. The findings may provide evidence for resistance training monitoring, individualized load prescription and practical strength assessment.
