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.
It comes down to how the heat is distributed. Both convection and conventional ovens are powered by gas or electricity. But the heat source in a conventional oven is stationary, usually radiating from the bottom, while in a convection oven a fan circulates the hot air around the chamber. Convection ovens allow for even, fast cooking because the temperature stays more consistent, whereas conventional ovens can have pockets of warmer or colder air. Hot air rises, so when cooking food on both racks, dishes on the bottom rack may undercook while the food on top burns, explains Allison Eckelkamp, media representative at General Electric.
