| Abstract | ||
| The current research aims at identifying the distinctive indicators of the comparative biomechanical efficiency for the Salto backward biked on balance beam during three levels of performance. The researcher used the experimental approach (one-group deign) through follow-up measurements. Sample (3 junior female gymnastics performers – 11- 12 old year phase) was purposefully chosen from the Military Institution Sports Club in Alexandria – Egypt. They were all beginners in learning the Salto backward biked skills. The researchers concluded the following distinctive biomechanical indicators to differentiated among the three three levels of performance (preliminary conformity – good conformity – master): Maximum fade out distinctive indicators are upper arm- forearm angle, horizontal acceleration, horizontal strength and resultant strength. Feet-off the beam distinctive indicators are foot-leg angle and resultant momentum. Flight and circling distinctive indicators are upper arm-trunk angle, thigh-leg angle, horizontal acceleration and resultant momentum. Feet-touching-the beam distinctive indicators are foot-leg angle and horizontal momentum. Stability and balance distinctive indicators are thigh-trunk angle, vertical momentum and resultant acceleration. Researchers also concluded the duration of performance for final phase and a predictive equations indicating the performance level of the Salto backward biked on the balance beam during three levels of performance | ||
