Abstract：
BACKGROUND: A common tactic used by athletes to improve performance, lessen tiredness, and hasten recovery is dietary supplementation. We aimed to assess the role of a microalgae dietary liquid supplement additivated with Copper 22.5% NRV in water polo players\' performance.
METHODS: Twenty male water polo players were split into two groups: ten (spirulina group) took a twice-daily nutritional supplement containing 15 mL of spirulina liquid extract (titrated in Phycocyanin 1 mg/mL) and additivated with Copper 22.5% NRV for eight weeks, and ten (the placebo group) did not take the supplement. Subjective evaluations were finished using the Athlete\'s Subjective Performance Scale (ASPS). Levels of the biomarker creatine phosphokinase (CPK) were also assessed.
RESULTS: The spirulina group\'s mean total ASPS score increased significantly from baseline to follow-up and was significantly better than that of the placebo group (p < 0.001). Conversely, ASPS ratings in the placebo group slightly decreased. A positive correlation between spirulina supplementation and less severe ASPS was found using correlation matrix analysis. However, there was a slight difference in CPK levels from the baseline to the follow-up in the spirulina group.
CONCLUSIONS: A dietary supplement comprising spirulina and copper may help water polo players\' subjective performance measurements by lowering muscular tension. Larger, randomized controlled trials are yet required.

摘要：
背景：运动员用来提高成绩的常用策略，减轻疲劳,加速恢复是饮食补充。我们旨在评估添加了22.5％NRV铜的微藻饮食液体补充剂在水球运动员表现中的作用。
方法：将20名男性水球运动员分为两组：10名（螺旋藻组）每天两次服用含有15mL螺旋藻液体提取物（用藻蓝蛋白1mg/mL滴定）的营养补充剂，并添加22.5％NRV铜，持续八周，和10（安慰剂组）没有服用补充剂。使用运动员主观表现量表(ASPS)完成主观评价。还评估了生物标志物肌酸磷酸激酶(CPK)的水平。
结果：从基线到随访，螺旋藻组的平均总ASPS评分均显着增加，并且明显优于安慰剂组（p<0.001）。相反，安慰剂组的ASPS评分略有下降。使用相关矩阵分析发现螺旋藻补充与较不严重的ASPS之间存在正相关。然而,螺旋藻组CPK水平从基线到随访有轻微差异.
结论：包含螺旋藻和铜的膳食补充剂可以通过降低肌肉张力来帮助水球运动员的主观表现测量。较大,目前还需要进行随机对照试验.
