e in the non-oxidative metabolism zone. More blood glucose means a higher r-value. In Figure 2C, women show a higher level of free fatty acids in the blood over the course of time. This is by a descent margin. Once again, this correlates with all of the other figures thus far. Women are using more fat as a source of fuel than men. Figure 3A and B deal with hormones found in both genders. Epinephrine and norepinephrine are hormones released by the body that stimulate the release of glucose into the blood from cells. Higher levels of glucose indicate that a higher metabolism of carbohydrate. Once again, this shows that women have a higher fat metabolism than men do when exercising at the same relative intensity. This study has produced a numbers of results that can lead to a conclusion on the effects of endurance exercise on metabolism depending on gender. During endurance exercise, there are many factors that all contribute to women having a lower r-value than men, and thus using more of a fat metabolism at the same relative intensity level. ...
