This investigation provides an insight into the physiological changes produced, and processes operating, during and after a typical interval exercise training regime. The role of interval exercise in the modulation of the plasma concentration of sex hormone binding globulin (SHBG) and the hormones beta-oestradiol, testosterone, prolactin and growth hormone was assessed. Eight trained male athletes [mean maximal oxygen uptake (VO2max) 64.3 (SD 3.8) ml.kg-1 x min-1, mean age 31.5 (SD 4.5) years] undertook an intense interval exercise (treadmill running) protocol to exhaustion. Subjects completed an average of 15.6 x 1-min runs. This interval protocol produced significant increase in the plasma concentration of SHBG and all four hormones (all P < 0.01) in the immediate post-test period. The plasma concentration of the hormones increased as indicated: beta-oestradiol (45%), testosterone (38%), prolactin (230%), growth hormone (2000%). These hormones have an established capacity to interact with components of many physiological systems and, as such, may provide a mechanism for the changes induced by intense exercise in many of these systems.
本研究深入探讨了在典型的间歇运动训练期间及之后所产生的生理变化以及相关作用机制。评估了间歇运动对性激素结合球蛋白（SHBG）以及β-雌二醇、睾酮、催乳素和生长激素等激素血浆浓度的调节作用。八名训练有素的男性运动员[平均最大摄氧量（VO2max）为64.3（标准差3.8）ml·kg-1·min-1，平均年龄31.5（标准差4.5）岁]进行了高强度间歇运动（跑步机跑步）直至力竭。受试者平均完成了15.6次1分钟的跑步。该间歇运动方案在测试后即刻使SHBG和所有四种激素的血浆浓度显著升高（均P<0.01）。激素的血浆浓度升高情况如下：β-雌二醇（45%）、睾酮（38%）、催乳素（230%）、生长激素（2000%）。这些激素具有与许多生理系统成分相互作用的既定能力，因此可能为剧烈运动在许多这些系统中引发的变化提供一种机制。
