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. Convection is the transfer of heat energy between a solid surface and the nearby movement of a liquid or gas (such as air). As fluid motion goes more quickly the convective heat transfer increases. The presence of bulk motion of fluid enhances the heat transfer between the solid surface and the fluid.onduction. Conduction is the transfer of the heat through a solid object, liquid or gas. In order for the heat to be conducted, there should be physical contact between particles and some temperature difference.
