Exercise in healthy adults has been shown to small but positive effects on cognitive function. Short term or working memory is a limited storage system in which a memory is lost or decays rapidly. Short term memory is believed to support an array of complex cognitive behaviors such as reading comprehension and mathematical problem solving (Beilock & Carr, 2005). The effects of exercise intensity on short term memory is varied, although submaximal and moderate exercise bouts have been shown to have a positive effect on memory. Exercise causes changes in cardiorespiratory, hormonal and metabolic processes that may increase the availability of oxygen, nutrients and glucose to the brain. The VO2 max test measures aerobic power. Every graded exercise test does not necessarily yield a true maximal oxygen consumption but will always result in a peak oxygen consumption. The Bruce Protocol, one of the earliest standard treadmill protocols developed, was used.
