    heat gain in a human systems while exercing

    MintJulep - I think we will need to prescribe on watts/kg body weight. We have some data that suggest this may work. In 35C with low humidity (30%), two groups - large (91.5kg) and small (67.6kg), both working at slightly different metabolic cost - 2.14 l/min vs 1.8 l/min, but when converted...

    heat gain in a human systems while exercing

    Chicopee - Will do. Thanks. IRstuff - This is not for a school project. It is a research study. We are interested in body temperature and it's influence on glucose metabolism in diabetic populations. So you can see, we are particularly interested in the rate of increase of body temperature...

    heat gain in a human systems while exercing

    I meant to increase from 37 to 38.5 in 30minutes then adjust work output to keep at 38.5C..

    heat gain in a human systems while exercing

    Willard3 - Where can I look for these ASHRAE volumes? Liteyear - Yes, we expect gross efficiency to be about 17% in exercising humans. You are correct. Thermoregulation of humans are effective via skin blood flow and skin temperature will actually cool to help with evaporative cooling. I like...

    heat gain in a human systems while exercing

    Resting energy expenditure is about.2-.5Lmin/O2, and there are 5kcal per liter of O2, which is about 1-2.5kcal per min. We can measure this value indirectly for each person.

    heat gain in a human systems while exercing

    A quick question that someone may be able to help me with. I am designing a research study exercising humans in a hot environmental chamber. How would I go about figuring out heat gain during exercise. I will have external work output - in watts (they will exercise on a cycle ergometer). I...
