The maximal volume of air that can be breathed in 1 min. It is the highest amount of ventilation that can be achieved during exhaustive exercise. In males, VEmax increases until physical maturity (from about 40 l min−1 at age 6 to more than 110 l min−1 maturity) and then decreases with ageing (to about 70 l min−1 for a 65-year-old). Females have a similar pattern of change, but generally have a smaller maximal expiratory volume at each age.
