Abstract

The purpose of this study was to conduct simultaneous measurement of counter movement vertical jump height using the XOS motion capture system and the Vertec system. Ten participants (body height: 170.17 cm ± 13.4, body weight: 79.76 kg ± 17.72) from the Marshall University student body comprised the testing group. Participants were instructed on proper counter movement vertical jump technique. Five practice jumps at 50% effort were conducted. Participants donned a compression suit with reflective markers. The paired t-tests indicated that a difference existed in counter movement vertical jump height measured between the Vertec and the XOS vertical jump was (p < 0.001), SEM of 1.4 with a .823 correlation and the Vertec and the XOS center of gravity was also (p < 0.001), SEM of 1.42 with a correlation of .788. A marked difference exists between the XOS SportMotion capture system’s methods of measuring counter movement vertical jump height when compared to the Vertec measurement.
