摘要


本研究采用柔性可穿戴传感器，对自然跑步状态下的运动-呼吸耦合（LRC）进行实时动态监测。对28名无系统训练史大学生，依据基线LRC变异系数（CV）分层（高、中、低变异组及对照组，每组n=7），实施4周、每周3次的6次/分静态慢呼吸（slow-paced breathing，SPB）干预，系统观察800米跑中LRC参数、运动成绩及心理适应性变化。结果显示，SPB训练可显著降低跑步后主观疲劳感，且在基线LRC-CV较高个体中效果更显著，支持静态训练心理效益向动态运动迁移的假说；客观指标中，800米成绩与LRC参数（CV、高效耦合时间占比）虽呈积极趋势，但未达统计学显著。本研究证实柔性传感LRC定量评估可有效识别训练响应的个体差异。
