ABSTRACT

As estratégias adotadas pelos corredores de "rua", durante as provas, sofrem interferência da distância da corrida e dos níveis técnico e físico dos competidores. Assim,o objetivo deste estudo foi de examinar os efeitos bioquímicos da Creatinina (C), Ácido Úrico (AU), Creatina Kinase (CK) e da Taxa de Filtração Glomerular (TFG) provocados por uma prova de corrida de "rua" de 6 (seis) Km. Participaram n=(15) atletas masculinos (40,53±8,65 anos) separados em 3 grupos: Grupo 1 Melhores Tempos (G1MT) n=5; Grupo 2 Tempos Intermediários (G2TI) n =5; Grupo 3 Piores Tempos (G3PT) n=5. Foram coletadas amostras de sangue 30 min antes e imediatamente após a corrida. Os dados foram analisados através da ANOVA Two-Way, Wilcoxon e Mann Whitney. Consideraram-se os níveis significativos (p<0,05). Os resultados permitem concluir que ocorreram aumentos significativos intragrupos nas atividades séricas de (C) no G1MT pré: 1,18±0,04 mg.dL-¹ pós: 1,60±0,15 mg.dL-¹; G2TI pré: 1,04±0,15 mg.dL-¹ pós: 1,56 ±0,21 mg.dL-¹; G3PT pré 1,08±0,13 mg.dL-¹ pós 1,52±0,32 mg.dL-¹ e no (AU) G1MT pré: 3,80±0,75 mg.dL-¹ pós 4,56±0,94 mg.dL-¹; G2TI pré 4,36±1,62 mg.dL-¹ pós 5,0 ±1,69 mg.dL-¹; G3PT pré 4,62±1,08 mg.dL-¹ pós: 5,42±0,86 mg.dL-¹, enquanto a (CK) e a (TFG) não apresentaram diferença significativa.


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.
