NCT00946855

Brief Summary

Repeated blood sampling within a regular soccer season of German first league clubs shall serve to define soccer-specific reference values for routine parameters determined from venous blood. It was hypothesized that only for a minor number of parameters common reference values will have to be adapted for soccer players during their competitive season.
