. By attaching absorbent patches to the skin to collect sweat, an increase in local skin temperature () underneath the patches seems unavoidable. Yet this effect has not been quantified. The present study investigates the effect of absorbent patch application on localunderneath.. Ten healthy participants cycled for 60 min at an exercise intensity relative to their body surface area (40 W.m) in three environmental conditions (temperate: 25 °C 45% RH, hot-humid: 33 °C 65% RH and hot-dry: 40 °C 30% RH). The effect of short sweat sampling (i.e. from min 25-30 to min 55-60) onwas examined on the right scapula.of the left scapula served as control. The effect of continuous sweat sampling (i.e. four consecutive 15 min periods) onwas examined on the right upper arm.of the left upper arm served as control.. Neither short nor continuous application of absorbent sweat patches affectedunderneath the patches in the hot-humid and hot-dry condition ( > 0.05). In the temperate condition, continuous application led to a significant increase inunderneath the patches during the first and second minute. This increase remained throughout the experiment (1.8 ± 0.6 °C; < 0.001). Short application of sweat patches did not affect the localunderneath ( > 0.05) in the temperate condition.. To avoid a significant increase in localunderneath sweat patches, continuous application should be prevented in, especially, a temperate condition. Timely removal of sweat patches should be taken into account during longer periods of collecting sweat in field or laboratories settings.
. 通过将吸水性贴片附着在皮肤上以收集汗液，贴片下的局部皮肤温度（）升高似乎是不可避免的。然而，这种影响尚未被量化。本研究调查了吸收性贴片应用对局部的影响。. 十名健康参与者在三种环境条件下（温带：25°C 45%相对湿度、湿热：33°C 65%相对湿度和干热：40°C 30%相对湿度）以相对于体表面积的运动强度（40 W.m）进行了 60 分钟的骑行。研究了短时间汗液采样（即从第 25-30 分钟到第 55-60 分钟）对右侧肩胛骨的影响，左侧肩胛骨作为对照。还研究了连续汗液采样（即四个连续 15 分钟时间段）对右侧上臂的影响，左侧上臂作为对照。. 在湿热和干热条件下，无论是短时间还是长时间应用吸收性汗液贴片，贴片下的均无明显变化（> 0.05）。在温带条件下，连续应用会导致贴片下的在第一和第二分钟内显著升高。这种增加在整个实验过程中持续存在（1.8 ± 0.6°C；< 0.001）。在温带条件下，短时间应用汗液贴片不会影响局部（> 0.05）。. 为了避免贴片下局部明显升高，特别是在温带条件下，应避免连续应用。在野外或实验室环境中长时间收集汗液时，应考虑及时去除汗液贴片。
