Haematological response of cyclists after competition

Resumen

The aim of the study was to analyze the hematologic response of cyclists after a nationwide competition level. Participated in 20 athletes (35 ± 7,90 years old, 1,75 ± 0,06m of height, 18,71 ± 4,12% of body fat, VO2max 57,90 ± 6,80 ml/kg/min, 345 ± 50,90W, 202 ± 6,77bpm of maximum heart rate), which underwent two blood samples, monitoring of body weight and water intake. After the competition was observed decrease in body weight (78,20 ± 9,10 to 76,70 ± 9,20 kg, p = 0,0001) with an average consumption of 620 ± 532,20 mL of water, and a significant increase (p = 0,0001) in the concentration of erythrocytes (5,28 ± 0,44 6 ± 0,41 million/mm3), hemoglobin (15,80 ± 1 to 17,70 ± 0,95 g/%), the platelets (211.950 ± 42.488,2 to 285.050 ± 47.097,2 un/mm3) and hematocrit (47 ± 2,97 to 54 ± 2,79%). Strong correlation (r > 0.7) between hematocrit with erythrocytes level and hemoglobin was observed. It was concluded that there is an increase in the number of hematological components of cyclists after competition with weak correlation with the water intake, body weight and the maximum volume of oxygen level
