aerobics

The term "aerobics" is a modern scientific coinage, constructed from classical Greek roots to describe a specific biological concept. It combines 'aero-', meaning "air" or specifically the oxygen within it, with a modified form of '-bics' from 'bios', meaning "life." The literal construction thus means "pertaining to life with air (oxygen)." This term was adopted in the 1960s by exercise physiologists to designate physical activity that improves the efficiency of the body's cardiovascular system in absorbing and transporting oxygen. The popular exercise regimen, developed by Dr. Kenneth H. Cooper and popularized in the 1980s, takes its name directly from this scientific principle, as the exercises are designed to increase oxygen consumption and promote the health of life-sustaining systems.

Structure: aero (air) + bics (life, living) - aero: From Greek 'aēr' (air, atmosphere). In this word, it functions as a combining form meaning "air" or "gas." - bics: From Greek 'bios' (life). In this word, it is a variant of the combining form 'bio-', indicating a relationship to life or living organisms.
