3 main concepts to understand Energy systems VO2/training adaptations Cardiac output q = SV x HR Cardiac output Q = SV x HR What is cardiac output? amount of blood from the heart Deliver oxygen and minerals and nutrients to the tissues Deliver things to tissues also brings carbon dioxide back (metabolic byproducts) What dictate levels of cardiac output? Demand. How much energy your muscles need. Intensity , measured by VO2. Volume of oxygen consumed. VO2 max test tests how much oxygen your body you can cconsume the more oxygen your body needs, the more its gonna stay in the body 100% VO2 is the highest functioning capacity of my body Intensity measured by vo2 has a direct correlation to cardiac output Maximally, if i want to increase cardiac out, i can control my stroke volume. Max HR = 220-age If I'm 45, and I train for 2 months, I raise my VO2 max, my max cardiac output increases, which means my SV and HR increase. If HR is a constant at 175 (220-45) then stroke volume is the variable. Know anatomomy Main focus is the heart in cardio and cardiac
