STUDY ON CENTRE OF GRAVITY IN LANDING CONDITIONS AFTER SPIKING IN VOLLEYBALL

Mr. Sunil Kumar Singh and Dr. Ratnesh Singh

Abstract

To compare whole body centre of gravity (CG) height in two distinct landing conditions after spiking in volleyball.  Method: Study area: Birbhum district in West Bengal, India. Subject: 10; age ranged 20-26 years.  The subjects were taken conveniently and they were the current intervarsity volley ball players who represent Visva-Bharati in the year, 2013.  The subjects were right-handed. Criterion measures: Whole body CG height at different conditions in two distinct landing condition.  Videography techniques were employed to collect data. Statistics: Mean, Standard Deviation and Independent t-test were used as statistical tool. Level of Significance was set at 0.05. Findings: The t-value of maximal CG height, CG height at horizontal velocity and CG height at vertical velocity of two distinct landing conditions after spiking volleyball were 1.042, 10.985 and 1.408 respectively. Result and Conclusion:   It reveals that CG height at horizontal velocity in long landing condition had significantly higher than normal landing condition after spiking volleyball.
