Influence of game side court on haematological and urinary biomarkers in professional padel players

Purpose: to analyze the influence of game side on court in haematological and urinary biomarkers after a simulated padel competition (SC) attending to possible gender differences. Method: pre- and post-SC serum creatinine, urea and creatine kinase (CK), and urine specific gravity and erythrocytes of twenty-nine professional padel players (16 women, 13 men) were quantified. A two-way ANOVA was used to show any differences in the studied variables (p values < 0.05). Results: significant differences were found before and after the SC for creatinine (p < 0.05) and erythrocytes (p < 0.01). Differences were found for creatinine (p < 0.001), CK (p < 0.01) and specific gravity between sexes (p < 0.05). No game side court effect was found. Conclusion: padel SC produced an increase in serum creatinine and hemolysis, probably caused by game dynamics. Sex differences were found in serum creatinine and CK, presumably due to anthropometric gender differences. Both sexes finished the SCs in a dehydrated state, affecting it more to men, something which should be considered to prevent and alleviate its potential negative effects in performance. More studies should be carried out to confirm these data.
