Our objective was to evaluate complex hormonal response in ball game and cyclic sport elite athletes through an incremental treadmill test, since, so far, variables in experimental procedures have often hampered comparisons of data.
We determined anthropometric data, heart rate, maximal oxygen uptake, workload, plasma levels of lactate, adrenaline, noradrenaline, dopamine, cortisol, angiontensinogen and endothelin in control (n = 6), soccer (n = 8), handball (n = 12), kayaking (n = 9) and triathlon (n = 9) groups based on a Bruce protocol through a maximal exercise type of spiroergometric test.
We obtained significant increases for adrenaline, 2.9- and 3.9-fold by comparing the normalized means for soccer players and kayakers and soccer players and triathletes after/before test, respectively. For noradrenaline, we observed an even stronger, three-time significant difference between each type of ball game and cyclic sport activity.
Exercise related adrenaline and noradrenaline changes were more pronounced than dopamine plasma level changes and revealed an opportunity to differentiate cyclic and ball game activities and control group upon these parameters. Normalization of concentration ratios of the monitored compounds by the corresponding maximal oxygen uptake reflected better the differences in the response level of adrenaline, noradrenaline, dopamine and cortisol.
我们的目的是通过递增式跑步机测试评估球类运动和周期性运动精英运动员的复杂激素反应，因为到目前为止，实验程序中的变量常常妨碍数据比较。
我们基于布鲁斯方案，通过最大运动类型的心肺运动试验，测定了对照组（n = 6）、足球组（n = 8）、手球组（n = 12）、皮划艇组（n = 9）和铁人三项组（n = 9）的人体测量数据、心率、最大摄氧量、工作量、血浆乳酸、肾上腺素、去甲肾上腺素、多巴胺、皮质醇、血管紧张素原和内皮素水平。
通过比较测试后/测试前足球运动员与皮划艇运动员以及足球运动员与铁人三项运动员的标准化均值，我们发现肾上腺素分别显著增加了2.9倍和3.9倍。对于去甲肾上腺素，我们观察到在每种球类运动和周期性运动活动之间存在更强的、三倍的显著差异。
与运动相关的肾上腺素和去甲肾上腺素变化比多巴胺血浆水平变化更明显，并且揭示了根据这些参数区分周期性运动和球类运动活动以及对照组的机会。通过相应的最大摄氧量对所监测化合物的浓度比进行标准化，能更好地反映肾上腺素、去甲肾上腺素、多巴胺和皮质醇反应水平的差异。
