The story of the word

Pasteur named the thing in the early 1860s, after finding fermentation microbes that died when air reached them; French anaérobie came first and English followed. Sports science borrowed the word much later and stretched it: an anaerobic sprint has plenty of air in the lungs, just not enough oxygen reaching the muscle in time. The ἀήρ inside it is the same air as in aerial and aerosol.
