... INTRODUCTION We investigated the density of mock blood in order to see the effect of exercise and altitude on the blood's efficiency at carrying the oxygen around the body. We tested out three mock blood samples. Sample A, the control sample, represents the blood of a normal, healthy adult male who lives at sea level. Sample B represents blood taken from the same male after he has undergone six months regular aerobic exercise. Sample C represents blood taken from the same male after he has spent three months undergoing aerobic training at high altitude. The relative density of protein-carrying fluids, such as blood, can be determined by measuring the rate at which drops of 'blood' fall under gravity through copper (II) sulphate solution, since a layer of copper proteinate forms around each drop, preventing the dispersal of the 'blood.'
