Without energy from respiration, organisms simply die. As an organism (in this case me, a human) does work, it needs more energy. Thus it will need more fuel and particularly more oxygen since glucose can be stored in the body. The oxygen intake increases as the rate of work done increases, up to a limit known as your VO2 max. VO2 max is the maximum volume of oxygen uptake (hence the V in VO2) anyone can use. It is measured in millilitres per minute per kilogram of body mass (mlO2 min-1 kg-1).
