Introduction We all learn in Biology 12 that physical activity increases our cardiovascular fitness that increases cerebral oxygen consumption via blood vessels. Moss and Scholey (1996) demonstrated improvements in memory with increase in level of oxygen supply to the brain before learning by oxygen administration. One suggested mechanism was increase in cardiovascular fitness could improve our cognitive function. Hill, Storandt, and Malley (1993) reported some studies which examined the effect of short-term exercise of two to four months …showed first 75 words of 1890 total…
