3D KINEMATIC AND KINETIC ANALYSES OF TWO METHODS FOR GRAB START TECHNIQUE
Keywords: biomechanics, swimming, grab start, kinematic, kinetic
AbstractThis study compared two swimming start techniques of GI (hands between the feet grab start technique) and GO (hands outside the feet) utilizing 3D simultaneous and synchronized kinematic and kinetic analysis. Eight experienced university swimmers were subjects of a series of specified trials. The comparison has consequently been made through evaluation of 46 variables obtained from force plate and motion analyzer. The results indicate that greater reaction force, resultant force in CM. and resultant moment about CM were produced in the GO than in GI. However, significantly higher values in reaction moment about horizontal axis and CM vertical coordinates were associated with GI. It has been shown that although GO will result in lower performance.
