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.
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.
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 ( < 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.
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.
运动员常采用饮食补充剂来提高运动表现、减轻疲劳和加速恢复。我们旨在评估一种添加 22.5%NRV 铜的微藻饮食液体补充剂对水球运动员表现的作用。
将 20 名男性水球运动员分为两组：10 名（螺旋藻组）每天服用两次含有 15 毫升螺旋藻液体提取物（以藻蓝蛋白 1 毫克/毫升为标准）和添加 22.5%NRV 铜的营养补充剂，持续八周，10 名（安慰剂组）不服用补充剂。使用运动员主观表现量表（ASPS）完成主观评估。还评估了生物标志物肌酸磷酸激酶（CPK）的水平。
螺旋藻组的平均总 ASPS 评分从基线到随访显著增加，明显优于安慰剂组（<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 ASPS 评分较低呈正相关。然而，螺旋藻组的 CPK 水平从基线到随访略有差异。
包含螺旋藻和铜的饮食补充剂可能有助于降低肌肉张力，从而提高水球运动员的主观表现测量。还需要更大规模的随机对照试验。
