RELIABILITY OF A FLIGHT TIME MEASUREMENT INSTRUMENT DURING VERTICAL JUMP
Keywords: reliability, contact mat, flight time, vertical jump
AbstractResearchers and practitioners who evaluate performance of study participants, patients, athletes or other clients, should use tests with high reliability, because these are the only tests that can have high validity. The aim of this study was to determine the reliability of a contact mat (CM). For this, sixteen volunteers had carried out a series of three vertical jumps in the test and had repeated the same procedure one week later in the retest. The flight time was registered by CM and force plate (FP) simultaneously. The result of the Mann-Whitney test showed that did not have significant difference between the test and retest in two instruments, and the correlation values were high between test and retest and between the instruments. From these results, it is concluded that the tested CM is a reliable tool to measure the flight time of the vertical jump.
