Aquatic based training can offer many of the same benefits associated with a land based exercises but water has certain properties that provide a more gentle and welcoming environment for exercising. Buoyancy in water counteracts gravity to support the weight of the subject and decrease the forces put on the joints. Viscosity of water can provide resistance proportional to the effort exerted and with gentle friction enhancing proprioceptive feedback. Immersing in warm water can cause an increase in body temperature due to specific heat and thermal conductivity, which can cause blood vessels to dilate. In addition, hydrostatic forces reduce edema, increasing venous return and healthy circulation. [Prins, 1999]; [Wilder, 1998]
