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.
The key point here is that heat is transferred through air circulation. Radiant heat otherwise known as thermal radiation is the most efficient type of heat transfer and the best example in our kitchen analogy would be the use of a microwave. Radiant heat is generated when heat from the movement of charged particles within atoms is converted to electromagnetic radiation. In a home or building, radiant heat refers to heat radiated from objects and materials, such as incandescent lights, concrete flooring and the sun.
