In elite sport, the Athlete Biological Passport (ABP) was invented to tackle cheaters by monitoring closely changes in biological parameters, flagging atypical variations. (frontiersin.org)
The further development of the Athlete Biological Passport with a careful monitoring of biological parameters still represents the most consistent approach to thwart athletes using undetectable prohibited substances or methods. (frontiersin.org)
Abnormal Blood Profile Score1
The estimate of doping prevalence was obtained by using a Bayesian network with seven variables, as well as "blood doping" as a variable mimicking doping with low-doses of recombinant human erythropoietin (rhEPO), to generate reference cumulative distribution functions (CDFs) for the Abnormal Blood Profile Score (ABPS) from the ABP. (frontiersin.org)
Hematological parameters5
This study estimates the prevalence of blood doping based on hematological parameters in a large cohort of track and field athletes measured at two international major events (2011 and 2013 WA World Championships) with a hypothesized decrease in prevalence due to the ABP introduction. (frontiersin.org)
Our results from robust hematological parameters indicate an estimation of an overall blood doping prevalence of 18% in 2011 and 15% in 2013 (non-significant difference) in average in endurance athletes [95% Confidence Interval (CI) 14-22 and 12-19% for 2011 and 2013, respectively]. (frontiersin.org)
This study describes a method to define blood doping prevalence with the analysis of robust hematological parameters. (frontiersin.org)
Longitudinal follow up of hematological parameters in different endurance sports, during the 1990s and early 2000s, has provided considerable suspicions about extensive blood manipulation, with performance enhancing effects. (dnf-is-no-option.com)
The Athlete's Biological Passport represents the progeny of the idea of an indirect approach based on long term monitoring of hematological parameters, thus making it possible to detect autologous blood doping and erythropoietin use after the substance is excreted. (dnf-is-no-option.com)

the present study aimed at revealing ABD-dependent changes of miRNA signatures in blood samples after ABD. (wada-ama.org)
Year1
Basso is no stranger to doping, but I am utterly stunned that Armstrong would be stupid enough to expect anything less than derision at the blood numbers he posted at the Tour last year. (cyclingnews.com)
Cells1
INTRODUCTION: Determination of blood volume (BV) using the dual-isotope (e.g., 99m Tc-labeled red blood cells [99m Tc-RBC] and 125 I-labeled human serum albumin [125 I-HSA]) injection method is limited in medicine due to the long isotope half-life. (bvsalud.org)

Delivery1
Erythropoiesis stimulating agents and autologous blood transfusions are used in synergy with substantial effect on the maximum oxygen uptake and delivery to muscles. (dnf-is-no-option.com)
Human1
The detection of illegal applied autologous blood transfusion is an everlasting and unsolved problem in the human doping scene. (wada-ama.org)
Predominantly2
The most important result of this project was the transfusion of autologous blood, predominantly with long-term storage for 7 weeks, lead to distinct changes of the RBC population shortly after transfusion. (wada-ama.org)
The non-cellular component of blood is the plasma, made up predominantly of water, but containing a large variety of proteins, minerals, and other substances. (athletesheart.org)
Oxygen5
The enhancement of oxygen transfer through blood transfusions was declared a prohibited method by the International Olympic Committee in 1984 and is banned by the World Anti-Doping Agency (WADA). (medscape.com)
Though there are acceptable ways to increase red blood cell counts like training at high altitudes and in low oxygen tents, autologous transfusions allow athletes to time their red blood cell counts to spike right before competing. (okorieokorocha.com)
The RBCs contain the iron-containing protein, hemoglobin , that allows the red blood cells to carry oxygen to the body's tissues. (athletesheart.org)
There is a feedback mechanism in which low blood oxygen levels stimulate production of Epo by the kidney, which in turn stimulates production of RBCs in the bone marrow. (athletesheart.org)
Doping6
In this context, the so-called 'neocytolysis' as a presumed selective destruction of young red blood cells (neocytes) was described as a process to possibly down-regulate hemoglobin mass when it is "excessive" or maladaptive for the environment and was seen as potentially important in blood doping settings. (wada-ama.org)
This project unfortunaly may not reveal a direct test for autologous blood doping at this stage. (wada-ama.org)
Of course now, most of the cheating is as a result of steroids, performance enhancing drugs and blood doping, but thanks to forensic toxicology, blood testing could be the answer to every sporting official's prayers. (okorieokorocha.com)
Though blood doping was frowned upon by officials, it wasn't illegal until 1985. (okorieokorocha.com)
Here's why blood doping is a problem: Athletes who receive an autologous transfusion, see up to a 25% increase in stamina. (okorieokorocha.com)
This is why forensic toxicologists from the World Anti-Doping Agency (WADA) have developed an " Athletic Biological Passport . (okorieokorocha.com)
Unequivocal1
Although autologous blood transfusions are a prohibited method, there is at present no unequivocal test and it seems from recent scandals that the technique remains a significant problem in various sports. (wada-ama.org)
Erythrocyte1
During the time course of a simulated cycling season (42 wk) including three major competitions (Classics, Grand Tour, World Championships), multiple autologous transfusions of erythrocyte concentrates were assigned in the doped group. (medscape.com)
Longitudinal2
The purpose therefore was to evaluate the performance of tHb as part of the adaptive model for the detection of autologous blood transfusions in a longitudinal blinded study. (medscape.com)
This project will consist of a cross-sectional and longitudinal part where multiple transfusions and a control group shall be included to test for reproducibility and specificity of the methods. (wada-ama.org)
Detection2
In this one-year project, our group focuses on the detection of autologous blood transfusion by a detailed analysis of red blood cell density fractions which could be altered in the time course after transfusion. (wada-ama.org)
Because of the elaborate preparations and short detection window (perhaps only valid for long stored blood). (wada-ama.org)
Direct1
While scientists can easily test for steroids and other hormones with blood and urine tests, they have no direct way of detecting autologous transfusions. (okorieokorocha.com)
Evaluate1
Flow cytometry with measurement of red blood cell surface markers shall be used to further evaluate these shifts and to allow identification of a certain set of markers being specific for autologous transfusion. (wada-ama.org)
Important2
Systemic reactions to autologous transfusions were supported by the analysis of classical markers such as serum ferritin and hematology measurements showing significant changes which support the high value of serum ferritin as an important marker of autologous transfusion. (wada-ama.org)
The RBCs far outnumber the white blood cells (WBCs), and it is the RBCs that are important for today's discussion. (athletesheart.org)
Time1
Using biomarkers, this "passport" tracks changes in an athlete's body over time, rather than foreign substances in the body. (okorieokorocha.com)
Group1
In a pilot study, as an unexpected, but compelling and promising finding, our group was able to show that the transfusion of autologous blood leads to a distinct shift in the red cell density fractions with an increase of red cells of a high density. (wada-ama.org)
Officials can begin to breathe easy now that forensic toxicologists can track spikes in red blood cell counts and see which athletes have played by the rules. (okorieokorocha.com)
