Meta-Analyze of the Scientific Papers on the Sport Balls Repulsion Depending on the Air Pressure within

J. Anthr. Sport Phys. Educ. 2019, 3(1), 55-57 | DOI: 10.26773/jaspe.190110

Abstract

The main goal of the research was to make one Meta-analyze of original scientific papers, who dealt with the identification on the sport balls repulsion depending on the pressure within. Sport balls of standard dimensions was released on the flat solid surface from the height of nine meters for four times. At the first release the air in the sport balls was under prescribed pressure. At the second release the pressure in the pumped sport balls is reduced by 5%, at the third reduced by an additional 5%, at the fourth reduced by another 5%. The setting of the experiment was carried by cinema shooting of free fall of the prescribed sport balls and a series of rebounds after the rejection of solid surfaces. One can conclude that the distance crossed and the total duration of four successive bouncing mostly dependent on inner pressure. In this study, the initial speed of a sport ball were unchanged and only inner pressures were changed. It was determined how much the height of the rebound is reduced and the duration of the rebound, respectively, depending on the reduction of inner pressure. This Meta-analyze shows that the initial speed of the ball can be increased by increasing the inner pressure in the balls.
