Effect of Soccer on Routine Urinalysis and Some Blood Biochemical Parameters
Abstract
The effect of soccer on routine urinalysis and some biochemical indices measured in laboratories has been studied, in order to review the changes that may result from such contact exercise. A total of 40 amateur soccer
players were used for this study in which urine and arterial blood samples were collected before and after soccer. The mean pH of urine decreased significantly (p<0.01) after soccer, while the mean post-soccer specific gravity of urine increased significantly (p<0.01), compared with the pre-soccer values. The post-soccer urine samples showed the presence of protein (albumin) ranging from 15-100mg/d1 in 37.5% of the players. There was also the presence of blood in the post-soccer urine (haematuria) ranging from 50 ery/μ1 and above in 15.0% of the players. The blood biochemical studies showed that the mean albumin level of the players was significantly higher (p<0.05) after soccer. There was significant increase (p<0.01) in the mean alanine aminotransferase (ALT) levels after soccer. The mean creatinine and haemoglobin values were significantly lower (p<0.05) when compared with their post-soccer values. None of the players developed significant hypernatraemia or hyperkalaemia after soccer. No changes were observed for aspartate aminotransferase (AST), alkaline phosphatase (ALP), total proteins, total bilirubin and conjugated bilirubin after soccer. Accordingly, health practitioners should particularly be aware of these potential biochemical changes that may result from contact exercise such as soccer.
