: Selenium (Se) is a trace mineral element with important roles in enhancing athletic performance and athlete recovery. : This study aimed to observe the differences in plasma, urinary, erythrocyte, and platelet Se concentrations between sexes and analyze the variations in Se concentrations during the soccer season. The main hypothesis was that significant differences in Se levels would be observed between male and female athletes and that these differences would fluctuate throughout the season due to varying training loads and nutritional factors. : Twenty-two male (20 ± 2 years; 1.76 ± 0.06 m; 14.73 ± 3.13 years' experience; fifth Spanish division) and twenty-four female soccer players (23 ± 4 years; 1.65 ± 0.06 m; 14.51 ± 4.94 years' experience; second Spanish division) participated. Three assessments were conducted during the season. Evaluations included anthropometry, body composition, fitness (cardiorespiratory and vertical jump), and nutritional intake. Venous samples of blood and urine were obtained. The concentrations of Se in the plasma, urine, erythrocytes, and platelets were analyzed through inductively coupled plasma mass spectrometry. : No differences in Se intake were observed. The Se concentrations in the plasma, urine, and platelets were found to be higher in males, while females showed elevated levels in their erythrocytes ( < 0.05). Throughout the season, plasma and platelet Se concentrations exhibited a progressive increase ( < 0.05). : Assessing Se status during the season is essential for evaluating nutritional supplementation to maintain performance given Se's vital role in the immune and antioxidant systems.
硒（Se）是一种微量矿物质元素，在提高运动表现和运动员恢复方面具有重要作用。本研究旨在观察男女之间血浆、尿液、红细胞和血小板中硒浓度的差异，并分析足球赛季期间硒浓度的变化。主要假设是，男女运动员之间的硒水平会存在显著差异，并且由于训练负荷和营养因素的变化，这些差异会在整个赛季中波动。22名男性（20±2岁；身高1.76±0.06米；有14.73±3.13年经验；西班牙第五级别联赛）和24名女性足球运动员（23±4岁；身高1.65±0.06米；有14.51±4.94年经验；西班牙第二级别联赛）参与了研究。在赛季期间进行了三次评估。评估内容包括人体测量、身体成分、体能（心肺功能和垂直跳跃）以及营养摄入。采集了静脉血样和尿样。通过电感耦合等离子体质谱法分析血浆、尿液、红细胞和血小板中的硒浓度。未观察到硒摄入量的差异。发现男性血浆、尿液和血小板中的硒浓度较高，而女性红细胞中的硒浓度较高（P<0.05）。在整个赛季中，血浆和血小板中的硒浓度呈逐渐上升趋势（P<0.05）。鉴于硒在免疫和抗氧化系统中的重要作用，在赛季期间评估硒状态对于评估营养补充以维持运动表现至关重要。
