To investigate clothing-induced differences in human thermal response and running performance, eight male athletes participated in a repeated-measure study by wearing three sets of clothing (CloA, CloB, and CloC). CloA and CloB were body-mapping-designed with 11% and 7% increased capacity of heat dissipation respectively than CloC, the commonly used running clothing. The experiments were conducted by using steady-state running followed by an all-out performance running in a controlled hot environment. Participants' thermal responses such as core temperature (T), mean skin temperature ([Formula: see text]), heat storage (S), and the performance running time were measured. CloA resulted in shorter performance time than CloC (323.1 ± 10.4 s vs. 353.6 ± 13.2 s, p = 0.01), and induced the lowest [Formula: see text], smallest ΔT, and smallest S in the resting and running phases. This study indicated that clothing made with different heat dissipation capacities affects athlete thermal responses and running performance in a hot environment. Practitioner Summary: A protocol that simulated the real situation in running competitions was used to investigate the effects of body-mapping-designed clothing on athletes' thermal responses and running performance. The findings confirmed the effects of optimised clothing with body-mapping design and advanced fabrics, and ensured the practical advantage of developed clothing on exercise performance.
为了研究服装对人体热反应和跑步表现的影响，八名男性运动员参与了一项重复测量研究，他们穿着三套服装（CloA、CloB和CloC）。CloA和CloB采用了人体映射设计，与常用的跑步服装CloC相比，散热能力分别提高了11%和7%。实验通过在受控的高温环境中进行稳态跑步，然后进行全力性能跑步来进行。测量了参与者的热反应，如核心温度（T）、平均皮肤温度（[公式：见正文]）、蓄热（S）以及性能跑步时间。CloA的性能时间比CloC短（323.1±10.4秒对353.6±13.2秒，p = 0.01），并且在休息和跑步阶段诱导出最低的[公式：见正文]、最小的ΔT和最小的S。这项研究表明，具有不同散热能力的服装会影响运动员在高温环境中的热反应和跑步表现。从业者总结：采用模拟跑步比赛实际情况的方案，研究人体映射设计的服装对运动员热反应和跑步表现的影响。研究结果证实了采用人体映射设计和先进面料的优化服装的效果，并确保了开发的服装在运动表现方面的实际优势。
