Intense exercise evokes a spleen contraction releasing red blood cells into blood circulation. The same mechanism is found following acute apnea, increasing [Hb] by 2 to 5%. The aim of this study was twofold: [1] to identify the optimal apnea modalities to acutely increase [Hb] and [2] use these modalities to examine whether pre-race apnea can improve a 3km time trial (TT).

Abstract
Intense exercise evokes a spleen contraction releasing red blood cells into blood circulation. The same mechanism is found following acute apnea, increasing [Hb] by 2 to 5%. The aim of this study was twofold: [1] to identify the optimal apnea modalities to acutely increase [Hb] and [2] use these modalities to examine whether pre-race apnea can improve a 3km time trial (TT).
