Abstract : A swimmer or diver encounters a variety of physiological stresses, including cold, fatigue and high partial pressures of oxygen, carbon dioxide, and inert gas. These of studies examine four such stresses: Resistance to gas-flow; immersion diuresis; hydrodynamic resistance; and the energy lost in accelerating the body while swimming through water. The common denominator among these is the generation of pressure, and the dissipation of energy required to generate this pressure. There are effects of the pressure gradients on the internal body structures.
