This study investigated the impact of permanently tattooed skin on local sweat rate, sweat sodium concentration and skin temperature and determined whether tattoos alter the relationship between local and whole-body sweat sodium concentration.
Thirteen tattooed men (27 ± 6 years) completed a 1 h (66 ± 4% of [Formula: see text]) cycling trial at 32 °C, 35% relative humidity. Sweat rate and sweat sodium concentration were measured using the whole-body washdown and local absorbent patch techniques. Patches and skin-temperature probes were applied over the right/left thighs and tattooed/non-tattooed (contralateral) regions.
Local sweat rates did not differ (p > 0.05) between the right (1.11 ± 0.38) and left (1.21 ± 0.37) thighs and the permanently tattooed (1.93 ± 0.82) and non-tattooed (1.72 ± 0.81 mg cm min) regions. There were no differences in local sweat sodium concentration between the right (58.2 ± 19.4) and left (55.4 ± 20.3) thighs and the permanently tattooed (73.0 ± 22.9) and non-tattooed (70.2 ± 18.9 mmol L) regions. Difference in local skin temperature between the right and left thighs (- 0.043) was similar to that between the permanently tattooed and non-tattooed (- 0.023 °C) regions. Prediction of whole-body sweat sodium concentration for the permanently tattooed (41.0 ± 6.7) and the non-tattooed (40.2 ± 5.3 mmol L) regions did not differ.
Permanent tattoos do not alter local sweat rate, sweat sodium concentration or local skin temperature during moderate-intensity cycling exercise in a warm environment. Results from a patch placed over a tattooed surface correctly predicts whole-body sweat sodium concentration from an equation developed from a non-tattooed region.
本研究旨在探讨永久性纹身对局部排汗率、汗液钠浓度和皮肤温度的影响，并确定纹身是否改变了局部和全身汗液钠浓度之间的关系。
13 名男性纹身者（27±6 岁）在 32°C、35%相对湿度下完成了 1 小时（66±4%[公式：见正文]）的自行车骑行试验。使用全身冲淋和局部吸收贴技术测量排汗率和汗液钠浓度。贴片和皮肤温度探头贴在右/左腿和纹身/非纹身（对照）区域。
右腿（1.11±0.38）和左腿（1.21±0.37）以及永久性纹身（1.93±0.82）和非纹身（1.72±0.81mg cm min）区域的局部排汗率没有差异（p>0.05）。右腿（58.2±19.4）和左腿（55.4±20.3）以及永久性纹身（73.0±22.9）和非纹身（70.2±18.9mmol L）区域的局部汗液钠浓度也没有差异。右腿和左腿之间的局部皮肤温度差异（-0.043°C）与永久性纹身和非纹身区域之间的差异（-0.023°C）相似。永久性纹身（41.0±6.7mmol L）和非纹身（40.2±5.3mmol L）区域的全身汗液钠浓度预测没有差异。
在温暖环境下进行中等强度的自行车运动时，永久性纹身不会改变局部排汗率、汗液钠浓度或局部皮肤温度。贴在纹身表面的贴片的结果与从非纹身区域开发的方程预测的全身汗液钠浓度相符。
