Plasma testosterone, noradrenaline, and adrenaline concentrations during three bicycle ergometer tests of the same total work output (2160 J X kg-1) but different intensity and duration were measured in healthy male subjects. Tests A and B consisted of three consecutive exercise bouts, lasting 6 min each, of either increasing (1.5, 2.0, 2.5 W X kg-1) or constant (2.0, 2.0, 2.0 W X kg-1) work loads, respectively. In test C the subjects performed two exercise bouts each lasting 4.5 min, with work loads of 4.0 W X kg-1. All the exercise bouts were separated by 1-min periods of rest. Exercise B of constant low intensity resulted only in a small increase in plasma noradrenaline concentration. Exercise A of graded intensity caused an increase in both catecholamine levels, whereas, during the most intensive exercise C, significant elevations in plasma noradrenaline, adrenaline and testosterone concentrations occurred. A significant positive correlation was obtained between the mean value of plasma testosterone and that of adrenaline as well as noradrenaline during exercise. It is concluded that both plasma testosterone and catecholamine responses to physical effort depend more on work intensity than on work duration or total work output.
在健康男性受试者中，测量了他们在三次自行车测力计测试期间血浆睾酮、去甲肾上腺素和肾上腺素的浓度。这三次测试的总功输出相同（2160焦耳/千克），但强度和持续时间不同。测试A和B分别由三次连续的运动回合组成，每次持续6分钟，运动负荷分别为递增（1.5、2.0、2.5瓦/千克）或恒定（2.0、2.0、2.0瓦/千克）。在测试C中，受试者进行了两次运动回合，每次持续4.5分钟，运动负荷为4.0瓦/千克。所有运动回合之间均有1分钟的休息时间。持续低强度的运动B仅导致血浆去甲肾上腺素浓度略有增加。递增强度的运动A导致两种儿茶酚胺水平均升高，而在强度最大的运动C期间，血浆去甲肾上腺素、肾上腺素和睾酮浓度显著升高。运动期间血浆睾酮的平均值与肾上腺素以及去甲肾上腺素的平均值之间存在显著正相关。得出的结论是，血浆睾酮和儿茶酚胺对体力活动的反应更多地取决于工作强度，而不是工作持续时间或总功输出。
