The Effect of a 12-Hour Fast on Maximal Aerobic Performance

Abstract

**Please note that the full text is embargoed** ABSTRACT: Maximum aerobic capacity (VO2max) is an indicator of physical fitness and a measurement of an individual’s ability to transport and utilize oxygen. It is measured in absolute terms in (L/min) and can be normalized with weight in (ml/kg/min). Often times food may not be considered a contributing factor to an individuals VO2max, however, ones diet could have a direct effect on their ability to perform incremental exercise to max. Research suggests fasting may have detrimental effects on individual’s ability to exercise, resulting in a lower VO2max and a quicker time to fatigue.
