Trace mineral element concentrations are under homeostatic control. Selenium (Se) is a very important micronutrient for the antioxidant and immune system. Se metabolism could be modified due to physical training. This research aimed to analyze the extracellular (plasma, urine and serum) and intracellular (platelets and erythrocytes) concentrations of Se in athletes and to compare it with subjects with low levels of physical training. Forty young men divided into a control group (CG; n = 20; 19.25 ± 0.39 years) and a training group (TG; n = 20; 18.15 ± 0.27 years) participated in this study. The TG was formed by semi-professional soccer players. The analysis of Se was determined by inductively coupled plasma mass spectrometry. The TG obtained higher values of maximum oxygen consumption and muscle percentage (p < 0.05). The TG showed reduced absolute (p < 0.01) and relative (p < 0.05) Se concentrations in erythrocytes and platelets in comparison to CG. Trace element assessments should not be limited only to extracellular compartments as there could be deficiencies at the intracellular level.
痕量矿物质元素浓度受体内平衡控制。硒 (Se) 是一种非常重要的抗氧化剂和免疫系统的微量营养素。由于体育锻炼，硒的新陈代谢可能会发生变化。本研究旨在分析运动员细胞外（血浆、尿液和血清）和细胞内（血小板和红细胞）的硒浓度，并将其与低水平体育锻炼的受试者进行比较。40 名年轻男性分为对照组 (CG; n = 20; 19.25 ± 0.39 岁) 和训练组 (TG; n = 20; 18.15 ± 0.27 岁)。TG 由半职业足球运动员组成。通过电感耦合等离子体质谱法测定 Se 的分析。TG 获得了更高的最大耗氧量和肌肉百分比值 (p < 0.05)。与 CG 相比，TG 显示红细胞和血小板中的绝对 (p < 0.01) 和相对 (p < 0.05) Se 浓度降低。痕量元素评估不应仅局限于细胞外隔室，因为细胞内可能存在缺乏。
