Changes in serum creatinine, uric acid, creatine kinase and glomerular filtration in street runners

Abstract

The strategies adopted by corridors "street" during the evidence from interference of the race distance and levels of technical and physical competition. The objective of this study was to examine the biochemical effects of Creatinine (C), Uric Acid (AU), Creatine Kinase (CK) and Glomerular Filtration Rate (GFR) caused by a test run of "street" of 6 (six) Km participated n=(15) male athletes (40.53 ± 8.65 years) divided into three groups: Group 1 Best Times (G1MT) n = 5, Group 2 Intermediate Times (G2TI) n = 5; Group 3 Times Worst (G3PT) n = 5. Blood samples were collected 30 min before and immediately after the race. Data were analyzed by Two-Way ANOVA, Wilcoxon and Mann Whitney test. It was considered significant levels (p<0.05). The results showed that there were significant increases in serum activities of intra-group (C) in G1MT before: 1,18±0,04 mg.dL-1 after: 1.60±0.15 mg.dL-1; G2TI before: 1,04±0,15 mg.dL-1 after: 1,56±0,21 mg.dL-1; G3PT before: 1,08±0,13 mg.dL-1 after: 1,52±0,32 mg.dL-1 and (AU) G1MT before: 3,80±0,75 mg.dL-1 after: 4,56±0,94 mg.dL-1; G2TI before: 4,36±1,62 mg.dL-1 after: 5,0±1,69 mg.dL-1; G3PT before: 4,62±1,08 mg.dL-1 after: 5,42±0,86 mg.dL-1, while (CK) and (GFR) showed no significant difference.
