The diagnosis of overtraining syndrome and overreaching poses a great challenge. Military training aims at improving the physical performance of the conscripts, but an excessive training load could also lead to overreaching. This study of Finnish conscripts provides new insights into the pathophysiology of overreaching and overtraining through amino acids concentrations. In addition to confirming the possible use of plasma glutamine/glutamate concentration to indicate and predict overreaching, we made a novel finding, i.e. low alanine and arginine concentrations might have a role in performance decrement and fatigue related to overreaching. Moreover, this study is the first to show the possible association between amino acids with putative neuronal properties and overreaching. Thus, the present findings might help to detect and prevent overreaching and offer a reliable diagnostic approach. In order to avoid overreaching, military training should be planned more periodically and individually, especially during the first four weeks of military service.

军事训练对血浆氨基酸浓度的影响及其与超标的关系。

对过度训练综合症和过度锻炼的诊断提出了巨大的挑战。军事训练旨在改善应征入伍者的身体表现，但过多的训练负荷也可能导致超标。这项对芬兰应征入伍者的研究为通过氨基酸浓度超范围和过度训练的病理生理学提供了新的见解。除了证实可以使用血浆谷氨酰胺/谷氨酸盐浓度来指示和预测超范围外，我们还做出了一项新发现，即低丙氨酸和精氨酸浓度可能与超范围有关的性能下降和疲劳。此外，这项研究是第一个显示氨基酸与推测的神经元特性和超范围之间可能联系的研究。从而，目前的发现可能有助于发现和防止超出范围，并提供可靠的诊断方法。为避免超车，应更定期和个别地计划军事训练，尤其是在服兵役的头四个星期。
