Training at VO2 max intensity causes the cardiovascular system to adapt by increasing cardiac output through increased stroke volume, and training also develops more capillaries in and around muscles which increases blood flow and enhances lactic acid clearance, thereby increasing lactate threshold

Dr. YeohEvidence Quote
“as your body increases its demand for oxygen from intense exercise your cardiovascular system begins an adaptive response to deliver more oxygen but increasing cardiac output through an increase in stroke volume another adaptive response to exercise and training is that you develop more capillaries in and around your muscles which allow increased blood flow to and from exercising muscles”
