Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Epo increases red blood cell production and hence the amount of oxygen that can be transported around the body. It is shown that prolonged use of synthetic Epo (rHuEpo) leads to an increase in the period of time a given physical work can be performed, therefore it will continue to be abused by athletes, especially in endurance sports.

The existing method for measuring the abuse of rHuEpo approved by the World Anti-Doping Agency (WADA) is based on differences in the sugar groups bound to rHuEpo and Epo produced in the body, respectively.

Proteomics is a method by which one can look at all the proteins in blood at the same time. Even proteins that have changed very little can be distinguished. The main objective of this project is to investigate the effect of prolonged treatment with rHuEpo on changes in blood proteins in healthy young men.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

No training + placebo

10 young men being investigated with 10 weeks apart. The will receive placebo injections twice a week. Blood samples, blood pressures as well as VO2-max tests will be obtained during the 10 weeks.

Group Type PLACEBO_COMPARATOR

Placebo

Intervention Type OTHER

placebo (saline) is administered using a small syringe under the skin every other day for the first 2 weeks, on 3 consecutive days during week 3, and once a week from week 4-12.

No training + EPO

10 young men being investigated with 10 weeks apart. During the 10 weeks participants will receive EPO injections twice a week. Blood samples, blood pressures as well as VO2-mas tests will be obtained during the 10 weeks.

Group Type ACTIVE_COMPARATOR

recombinant human erythropoietin

Intervention Type DRUG

rHuEpo (5000 IU)is administered using a small syringe under the skin every other day for the first 2 weeks, on 3 consecutive days during week 3, and once a week from week 4-10.

Training + placebo

10 young men will be trained for 10 weeks and investigated before and after. They will receive placebo injections twice a week. Blood samples, blood pressures as well as VO2-max tests will be obtained during the 10 weeks.

Group Type ACTIVE_COMPARATOR

Training

Intervention Type BEHAVIORAL

For ten weeks participants will receive supervised endurance training on a bike three times a week. Physical effect will be examined with VO2-max tests before during and after the training period.
