Twelve weeks of sprint interval training increases maximal cardiac output

The improved maximal oxygen uptake (V̇O2max) after traditional moderate intensity continuous training (MICT) is generally attributed to increased maximal cardiac output (Q̇max). Sprint interval training (SIT) increases V̇O2max similar to MICT despite a lower training volume, but the effect on Q̇max is unclear. Purpose: To determine the effect of ~30 sessions of SIT over 12 weeks on Q̇max and its association with the change in V̇O2max. Methods: …
