Abstract

The purpose of the study was to verify the possibility applicable for exercise theraphy of underwater by investigation of exercise effect on the basis of result of kinematic analysis according to the loads of %BW of SCUBA apparatus loaded in underwater activities. The experimental method was based on 3D cinematography analysis on repeative gaits(3 times) according to the load of %BW of SCUBA apparatus with very skilled diver in underwater activities in pool of 5m underwater depth(25m X 25m X 5m). When considering kinematic variables from analysis, load increase of %BW was resulted in more stable gait by generating a negative buoyancy counteracting effect of positive buoyancy. Also It could be considered that a method minimizing buoyancy & resistance of water in course of propulsion was to increase to a specific level of the load of %BW. That resulted in more stable & efficient gait. When considering the above, It will be assumed that improvement of exercise and therapy effect of underwater could be elevated by proper application the relationship of resistance & propulsion in condition submerged of whole body.
