Abstract
Hematological values, selected blood chemical parameters and some urinary excretion of solutes were studied in 9 male athletes who participated in 10,000 meter running competition during 14th Physical Education College Sport Competition 1989, with age ranging from 18-22 years (20.0+0.5 yrs) and their maximum oxygen uptake (Vo(,2) max) were 56.0+2.8 ml/min/kg. By studying comparison between prerace and postrace conditions and concomitant compared with non-athlete controls, 10 male students with age ranging from 18-23 years (20.2+0.4 yrs) and their maximum oxygen uptake were 38.4+1.4 ml/min/kg. Body weight and height of these two groups are not different. The race started at 07:00 p.m. with ambient temperature of 27.5 C and relative humidity of 59%. After 10,000 meter race only 7 runners completed the race with body weight loss of average 2.65% and the time for complete the race were ranging from 33.0-57.13 min. Venous blood and urine samples were collected before and after the race. In each blood sample, red blood cells and white blood cells count, hematocrit values, hemoglobin concentration, plasma hemoglobin concentration, plasma osmolarity, total plasma protein, albumin, globulin, blood glucose, uric acid blood urea nitrogen (BUN), and creatinine concentration were determined. From some hematological values, mean corpuscular volume (MCV), mean corpuscular hemoglobin (MCH), and mean corpuscular hemoglobin concentration (MCHC) were calculated. Urinary excretion of solutes were estimated with Combus 8 Test, eight-patch test strip for the determination of nitrite, pH, protein, glucose, ketone bodies, urobilinogen, bilirubin, and blood/hemoglobin in urine. If was found that hemoglobin concentration in athletes were significantly higher than the controls (P<0.01), RBC count in athletes after the race were significantly decrease from prerace values (P<0.01). Plasma hemoglobin concentration was significantly higher in athletes when compared with non-athlete controls (P<0.01). From blood chemical analysis, total plama protein, albumin and uric acid concentration were significantly lower (P<0.01), whereas blood urea nitorgen (BUN) was significantly higher than the values were found in non-athlete controls. An increase in plasma globulin, creatinine and uric acid whereas blood urea nitorgen (BUN) concentration was decreased in athletes after the race were observed. However, there was a markedly increase in urinary protein after the race. It is likely that proteinuria was occurred after 10,000 meter race in well trained distance runners and hemolysis was observed during training and competition.
