AI 中文摘要
公开水域游泳属于热相边界问题，代谢产热与环境散热相互竞争。我们推导了一个标度律，可预测临界水温，并说明体型、游泳速度和隔热性能如何改变该边界。纵向的暖水和冷水数据显示，瞬态动态超出单室模型预测，但可由核心-外周生理机制自然解释。综上，研究表明热安全取决于游泳者个体特征和游泳条件，而非仅由水温决定。
英文摘要
Open-water swimming defines a thermal phase-boundary problem in which metabolic heat production competes with environmental heat loss. We derive a scaling law that predicts the critical water temperature and shows how body size, swim pace, and insulation shift this boundary. Longitudinal warm- and cold-water data reveal transient dynamics that exceed single-compartment predictions, but emerge naturally from core--peripheral physiology. Together, our results suggest that thermal safety depends on swimmer-specific characteristics and swimming conditions, not on water temperature alone.
