The second being the Anaerobic Glycolytic System which the body relies primarily
on anaerobic metabolism for the energy required to perform intensive exercise of greater than 12 - 15 seconds and less than 3 minutes duration (2).
Not exact matches
A disadvantageous consequence, however, is that the muscles in the limbs must then rely more
on anaerobic energy
metabolism to keep working, so they build up lactic acid and tire more rapidly than they would from comparable exercise at the surface.
The theorized
anaerobic life form, which is capable of performing reproduction and
metabolism in a manner similar to that of life
on earth, indicates that life is capable of thriving
on Saturn's moon Titan.
On the other hand all of the carbs used by the
anaerobic system can be created in the liver by fat

I slowly built up my level of training volume focusing

metabolism in my view is when glycogen stores are not completely full.
But the real truth it is right after the age of 25 years every 10 years your
metabolism drops at least 2 to 4 % and the only way to truly combat the natural metabolic decline that happens with after the age of 25 is being
on a consistent (aerobic &
anaerobic) exercise and sensible balanced nutritional program.
When you challenge your
metabolism with exercise when you don't have a lot of carbs to use for fuel, two things happen: your athletic output (which, in your case, depended
on carbs) drops because you only have fats to burn, and your energy levels also drop because when your fat - burning
metabolism gets exhausted, there's no other energy system to pick up the slack: even though the
anaerobic (sugar - burning)
metabolism isn't exhausted, it doesn't have any fuel to burn.
Buried in AVMA's 2013 Guidelines
on Euthanasia of Animals is the admission that has been in its previous Euthanasia reports: «Reptiles, amphibians, and diving birds and mammals have a great capacity for holding their breath and
