So long as we increase our exercise intensity slowly, we can maintain our muscles' dependence on aerobic metabolism, and we don't experience symptoms of fatigue. However, as exercise intensity increases, the need for energy release eventually exceeds that which can be supplied by aerobic metabolism.Our muscles simply need more reactions to support the energy demand. Therefore, anaerobic contribution to metabolism increases.o long as we increase our exercise intensity slowly, we can maintain our muscles' dependence on aerobic metabolism, and we don't experience symptoms of fatigue.

Radiant heat has considerable advantages over convected heat for comfort heating because: 1  Radiant heat has a higher âfluxâ (watts output per metre per degree centigrade of the heater) than convection heating. 2  A Radiant heater directly heats objects in an environment, not the air in between.
Convection. 1  Convection is the transfer of thermal energy through movement of particles from one location to another. 2  Usually occur in fluids (liquids and gases). 3  Example with boiling water: 4  Water at bottom of pan is heated first. 5  Heated water expands and density decreases. 6  Heated water begins to rise.
