Abstract

PURPOSE

To assess the effect of low-to-moderate-intensity exercise on specific blood biomarkers and blood acidity in young Saudi Arabian professional soccer players.

METHODS

A total of 43 professional soccer players participated in the current study. A cross-sectional research method was used to compare the changes in the following blood biomarkers: calcium, magnesium, glucose, anion-gap metabolic acidosis, and carbon dioxide, after a range of low-to-moderate intensity training sessions. Measurements were taken in two soccer training sessions (Day 1, and Day 2). The exercise intensity was estimated by heart rate percentage of maximal heart rate. Wilcoxon signed-rank testing was used to analyze the results.

RESULTS

Significant differences were found between and pre-and post-training sessions for anion-gap metabolic acidosis: Day 1: 12.55 vs 15.4 mmol/L; Day 2: 14.15 vs 16.35 mmol/L; and magnesium: Day 1: 0.82 vs 0.74 mmol/L; Day 2: 0.85 vs 0.74 mmol/L. Exercise caused anion-gap metabolic acidosis concentrations to rise post-training; magnesium levels decreased after training sessions on Day 1 and Day 2.

CONCLUSION

The concentrations of anion-gap metabolic acidosis and magnesium were significantly affected by exercise intensity in the subjects, the former rose post-training while the latter fell. More studies are required to investigate the effects of different exercise intensities on other blood biomarkers in soccer players.

摘要

目的

评估低至中等强度运动对沙特阿拉伯年轻职业足球运动员特定血液生物标志物和血液酸度的影响。

方法

共有43名职业足球运动员参与了本研究。采用横断面研究方法，比较一系列低至中等强度训练课程后以下血液生物标志物的变化：钙、镁、葡萄糖、阴离子间隙代谢性酸中毒和二氧化碳。在两次足球训练课（第1天和第2天）进行测量。运动强度通过最大心率的心率百分比来估计。采用Wilcoxon符号秩检验分析结果。

结果

训练前后阴离子间隙代谢性酸中毒存在显著差异：第1天：12.55 vs 15.4 mmol/L；第2天：14.15 vs 16.35 mmol/L；镁：第1天：0.82 vs 0.74 mmol/L；第2天：0.85 vs 0.74 mmol/L。运动导致训练后阴离子间隙代谢性酸中毒浓度升高；第1天和第2天训练课后镁水平下降。
