运动对皮肤屏障功能的影响

Effects of exercise on skin barrier function

目的探究运动是否对人皮肤屏障功能有影响。方法将符合纳入排除标准的28名青少年长跑运动员和28名健康非运动员作为研究对象。对其额中部、胸部、肘窝及腹股沟的皮肤表面pH值、经皮水丢失(transepidermal water loss,TEWL)值、皮脂含量和角质层含水量进行检测,并分别根据是否为运动员、性别(男性组、女性组)、年龄(≥14岁组,<14岁组)进行分组比较。根据运动员是否有使用润肤剂的习惯进行分组,比较上述5项指标。结果在所有5个分组中,运动员组的皮肤表面pH值显著高于对应的非运动员组(P<0.001)。运动员组在胸、肘窝、腹股沟的TEWL平均值显著高于健康非运动员组相应部位的TEWL平均值(P<0.05)。运动员组胸和肘窝的皮脂含量均显著低于非运动员组(P<0.05)。运动员组在额中部、胸、肘窝、腹股沟的角质层含水量平均值显著低于健康非运动员组相应部位的角质层含水量平均值(P≤0.001)。使用润肤剂组肘窝皮脂含量较高,腹股沟TEWL值较低,角质层含水量较高(P<0.05)。结论运动员的皮肤生理屏障功能较健康非运动员差,使用润肤剂对运动员的皮肤屏障功能有一定的修复作用。

Objective To explore whether exercise has an effect on skin barrier function.Methods Twenty-eight adolescent distance runners and 28 healthy non-athletes who met the inclusion and exclusion criteria were included as subjects.Skin surface pH,transepidermal water loss(TEWL)value,sebum content and water content of stratum corneum in the forehead,chest,elbow and groin were detected according to whether it was athlete,gender(male or female group),age(≥14 years old or<14 years old group)were compared.We also compared the above five indicators according to whether the athletes have the habit of using emollients.Results In all five subgroups,the skin surface pH of the athlete group was significantly higher than the corresponding non-athlete group(P<0.001).The average TEWL of the athletes in the chest,elbow and groin was significantly higher than the TEWL mean of the corresponding parts of the healthy non-athletes(P<0.05).The sebum content of the chest and elbow in the athletes group was significantly lower than that of the non-athlete group(P<0.05).The mean water content of the stratum corneum in the forehead,chest,elbow and groin of the athlete group was significantly lower than that of the corresponding part of the non-athlete group(P≤0.001).Compared with the non-emollient group,the sebum content of the elbow was higher,the TEWL value of the groin was lower,and the water content of the stratum corneum was higher in the emollient group(P<0.05).Conclusion The skin barrier function of athletes was worse than that of healthy non-athletes.Using emollients can help to repair the skin barrier function for athletes.
