In this context, the study ‘Hematologic changes after short term hypoxia in non-elite apnea divers under voluntary dry apnea conditions’ provides new insights revealing exhaustive data on all three blood cell lines up to four hours after acute static apnea. [...]the World Anti-Doping Agency (WADA) uses a very strict blood collection procedure to set up the Athlete Biological Passport [11]. [...]the athlete has to remain seated with both feet on the floor for at least 10 minutes before blood collection.
