采用基底皮肤电位（BSPL）程序，在3个表皮水化水平下，研究了青年和老年男性皮肤电位（SPL）的年龄差异。在水合作用最少的部位使用乙二醇培养基。蒸馏水和琼脂溶液是在另外2个更多水合位点处的培养基，其也在蒸馏水中接受0分钟或15分钟预处理。所有研究中心均使用浓度为0.5%的KCl电解质。年龄和水合作用的显著影响取决于进行比较时记录会话中的点。老年男性有显着较低的SPL比年轻男性在开始记录与乙二醇电解质介质，有没有显着的年龄差异，在开始记录与琼脂培养基，或在BSPL与任何水合条件。水化显着影响SPL幅度在开始记录，但不是在BSPL。在记录中的某些点用乙二醇介质记录的SPL与老年男性的户外活动显着相关。这种效应与心血管状态的差异无关，心血管状态与乙二醇SPL无显著相关性。老年时汗腺电位降低，这只有在记录条件产生高表皮电阻时才能观察到。这种降低的汗腺潜力与户外活动水平低有关。
Age differences in skin potential level (SPL) of young adult and aged men were investigated using basal skin potential level (BSPL) procedures at 3 levels of epidermal hydration. A glycol medium was used at a site of least hydration. A distilled water and agar solution was the medium at 2 other more hydrated sites which also received either 0 min or 15 min pretreatment in distilled water. A 0.5% KCl electrolyte concentration was used at all sites. Significant effects for age and hydration were dependent on the point in the recording session when comparisons were made. The old men had significantly lower SPL than did the young men at the start of recording with the glycol electrolyte medium; there were no significant age differences at the start of recording with the agar media, or at BSPL with any hydration condition. Hydration significantly affected SPL magnitude at the start of recording, but not at BSPL. SPL recorded with the glycol medium at certain points in the recording was significantly related to outdoor activity among the aged men. This effect was independent of differences in cardiovascular status, and cardiovascular status was not significantly correlated with glycol SPL. There is a reduced sweat gland potential in old age which can only be observed when recording conditions produce high epidermal resistance. This reduced sweat gland potential is related to low levels of outdoor activity.
