The research of hemoglobin mass on athletic biological passport for blood doping detection / 中国应用生理学杂志

OBJECTIVE@#To research the changes of blood parameters on different time points after micro-rHuEPO injection on young men and hope to provide evidences for Athletic Biological Passport (ABP) using in the detection of blood doping.@*METHODS@#Fourteen health young men were injected with micro-rHuEPO for 7 weeks, twice per one week.The subjects were treated with ferralia 105 mg every day during the injections.The control group was administrated with the same volume of saline solution injection and placebo 105 mg.The blood parameters (red blood cell, hemoglobin, reticulocyte, total hemoglobin, plasma volume, etc) were tested 11 times (7 days before the first injection, 3, 10, 17, 24, 31, 38 and 45 days after the first injection, 1, 2 and 3 weeks post the seventh week of last injection).By analyzed these total and concentration parameters, hope to know the effective of two kinds of parameters on ABP.@*RESULTS@#The levels of RBC and[Hb] were increased sharply after two weeks of injection and reached the peak in 5-6 weeks (9-10%, <0.01).It sustained till 3 weeks after the last injection.Total hemoglobin was increased significantly during the whole procedure of injections and reached the peak in week 5 (10%, <0.01) till 1 week after the last injection.Red blood cell volume was increased with the EPO injection and reached the peak in week 5 (<0.01), but blood volume wasn't increased significantly.Plasma volume was decreased with EPO injection and it was hemoconcentration.@*CONCLUSIONS@#It can enhance the total and concentration parameters through 7-week micro-rHuEPO injections and the total haemoglobin is more sensitive.So tHb can be used to detect blood doping in ABP.At the end of the last injection, the total blood parameters, such as the total hemoglobin, returned to normal, while the concentration index remained highly, possibly as a result of blood concentration.

Biometría hemática en el control médico del entrenamiento de deportistas cubanos de alto rendimiento / Hematic biometry in medical training monitoring of cuban high-performance athletes

Introducción: el control médico del entrenamiento deportivo lleva implícita la medición de parámetros hematológicos y de los índices eritrocitarios, incluido el conteo de reticulocitos, además de controles bioquímicos para velar por el estado de salud del deportista y obtener mejores resultados deportivos. Objetivo: analizar el comportamiento de las variables de los estudios hematológicos realizados a los deportistas de las preselecciones que participaron en los juegos Panamericanos Guadalajara 2011. Método: se realizó un estudio descriptivo transversal que tuvo como universo a 804 deportistas de alto nivel que integraban las preselecciones nacionales que se preparaban para constituir los equipos nacionales que participarían en los Juegos Panamericanos en Guadalajara, México, 2011. A todos se les realizó el perfil hematológico como parte del pasaporte biológico establecido para este tipo de competición. Además, a 328 se les realizó electroforesis de hemoglobina. Resultados: se encontraron cifras de hemoglobina y hematocrito significativamente más bajas en el sexo femenino. La concentración de hemoglobina corpuscular media presentó diferencias significativas por grupo de deporte. En los deportistas a quienes se les realizó electroforesis de hemoglobina se encontraron 15 AS. Conclusiones: los hallazgos de esta investigación son de gran utilidad para el diagnóstico y seguimiento de la salud de los deportistas de alto rendimiento sometidos a fuertes cargas físicas de trabajo(AU)

Introduction: medical management of sports training implies the measurement of hematological parameters, red cell indices, reticulocyte count and biochemical controls to care for the athletes´ health condition and to obtain higher sports scores. Objective: to analyze the behavior of the variables in hematological studies of athletes who participated in the presets Pan American Games Guadalajara 2011. Methods: a descriptive cross-sectional study was carried out with a universe of 804 high-performance athletes from national teams, who were training to participate in the Pan American Games in Guadalajara, Mexico, 2011. Hematological profile was performed as part of the biological passport established for this type of competition. Additionally, a hemoglobin electrophoresis was carried out in 328 of them. Results: significantly lower hemoglobin and hematocrit figures were found in females. The Mean Corpuscular Hemoglobin Concentration (MCHC) showed significant differences by group of sports. In athletes who underwent electrophoresis, Hb 15 AS were found. Conclusions: the findings of this research are useful for diagnosis and health monitoring of athletes of high-performance, under heavy physical workloads(AU)
