Abstract

The effects of strenuous exercise on lymphocyte beta-adrenoceptor density and responsiveness in nine men were biphasic. There was an initial increase in receptor density, seen immediately after exercise, with a subsequent decline to below pre-exercise values. In parallel, maximum isoprenaline-stimulated cyclic AMP production by lymphocytes was greatly increased at the end of exercise and decreased thereafter. The increases seen at the end of exercise may be of functional significance and may represent a response of the tissue to the demands placed upon it. After a time, however, a desensitization process takes over, possibly with a protective role.

摘要

剧烈运动对9名男性淋巴细胞β - 肾上腺素能受体密度和反应性的影响是双相的。运动后立即出现受体密度的初始增加,随后下降至运动前水平以下。与此同时,淋巴细胞对异丙肾上腺素刺激产生的最大环磷酸腺苷(cAMP)产量在运动结束时大幅增加,之后下降。运动结束时出现的增加可能具有功能意义,可能代表组织对其所承受需求的一种反应。然而,一段时间后,脱敏过程开始起作用,可能具有保护作用。
