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.
Radiation. 1  Radiation refers to the emission of energy in rays or waves. 2  Convection. 3  Convection is the transfer of heat by the physical movement of hot masses of air. 4  Conduction. Conduction is the transfer of heat within the material itself. Most metals are good heat conductors. Wood is a very poor conductor so it transmits heat very slowly. This can be illustrated by the fact that a wooden handle on a hot frying pan remains cool enough to be held by the bare hands.
