Temp regulation lab 4/7/08 1. The exercise period performed on the Vmax machine projected a mean RER of . 746. Using the chart, this value correlated with 84.4% fat, 15.6% CHO and every liter of O2 burned 4.739 kcals. (2). The total energy required for the entire exercise bout was 303.959 kcals and 38.864 grams of substrate. During the exercise bout, the Vmax subject lost.1 kg, the other 2 subjects lost .21 kg and .4 kg. The relationship clearly demonstrated that during 30min of exercise, the mass (grams) of substrate burned is WAY less than the amount of water you have remaining in your body, in other words, the majority of weight loss during exercise is due to water loss. 2. a.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
