c cart and Hans Rudolf masks. Measurements were made continuously for periods of 30 min, with recalibration performed between measurements. Blood samples were drawn for the determination of circulating substrate and hormone levels every 30 minutes on exercise day, and every hour during control day. Results were obtained and conclusions were able to be drawn a follows.Although a cross sectional study had been conducted, the trained and untrained aspects of the experiment resulted to be less significant than intended. In other words, in comparing trained men against trained women, and untrained men against untrained women, no significant differences could be drawn due to training. There was significant change in the dependent variable from the data obtained that conclusions were drawn from. The first is shown in Figure 1. The relationship shows the fat free mass of each gender against the subject’s resting metabolic rate. The resting metabolic rate on cycling and controlled days were averaged for all figures. For women, r=. 52 and for men, r=. 67. This already shows that women have a lower value and are more likely to have a greater lipid metabolism than men. As exercise intensity increases, the value of r increases toward a value of one. This is an anaerobic, carbohydrate-metabolizing zone. Figure 2A is a comparison of lactate levels against time for both genders. Men show a higher level of lactate throughout the entire timeline. Lactate, or lactic acid, is a result from the non-oxidative production of ATP, also know as glycolysis. The source for this is glucose, which comes form carbohydrates. It can inferred that men were using more CHO and less fat in their metabolism than women. Figure 2B shows that men had a significantly higher level of glucose in the blood over time. The reason for this is the same as mentioned above. Men were at a higher r-value than women and thus were closer to the value of one and wer...
