MgCO3 is a fairly insoluble salt, but it will dissolve to some degree in water and in slightly acid conditions it should form Mg ions (a micronutrient) and bicarbonate (HCO3-). As an aside this bicarbonate may help buffer any lactic acid buildup that may be occurring during the workout. I'm not sure how quickly or how much chalk will dissolve in the lungs, but my guess is that the lungs are slightly acidic b/c the CO2 will form a weak acid in solution and help the above reaction allowing Mg to be absorbed into the blood. This dissolution, I'm guessing would prevent lung damage b/c it is the physical irritation of a particulate that causes problems (asbestos also punctures tissues initiating a damage response in lung tissues - scarring).

This is from a biology/chemistry perspective. Any second opinions from medical doctors out there?
