Document Summary
Oxygen consumption and cardiac output are intimately linked. No: a huge increase in ventilation is over and above what is required, to get oxygen into the blood with hemoglobin, cardiac output (oxygen delivery), this does limit maximal aerobic exercise. Need both to run fast: predominantly glycolytic. If we got to 400 watts on the test If we sprint for 10-15 seconds we could generate 600-700 watts. Powerful = 1400 watts: need a high power outout, need to work hard and run quickly for us to recruit those glycolytic fibers. Less than fast oxidcative fibers: 2b is in more animals, skeletal muscle, voluntary, cardiac muscle, controls itself with assistance, from the nervous and endocrine systems (adrenal gland), only in the heart, smooth muscles. Involuntary muscle: controlled unconsciously in the walls of blood vessels and internal organs: receptors in the smooth muscle that respond to changes in pp of o2, anatomy.
