If you lose 2 pounds of weight during 30 minutes of aerobic exercise and do not ingest any fluid, estimate the fluid loss from ECF and ICF components and subcomponents, and the contributions from insensible and sensible mechanisms. Justify the loss from each compartment and each mechanism. Include changes in hormonal balance to facilitate the changes. Would you expect a greater change in fluid shift from diffusion, osmosis or facilitates diffusion? Why? Would you expect a greater fluid shift from running or swimming? Why? If you were working at 7 METS what is the maximal amount of metabolic water you can produce in 30 minutes why?
