Aragan-Vargas Evaluation of Four Vertical Jump Tests: Methodology, Reliability, Validity, and Accuracy in 'Measurement in Physical Education and Exercise Science' Dec 2000, 4(4): 215 - 228 Abstract: Vertical jump performance tests can give considerably different results, even when different methods are used to analyze the same jump trial from the same subject. To evaluate and compare 4 different methods commonly used to measure vertical jump performance, 52 physically active men each performed 5 maximal vertical jumps. Kinetic and kinematic data were used to analyze each trial using the 4 methods: a criterion test based on body center of mass displacement (VJPT), 2 methods based on vertical takeoff velocity as calculated from the force platform, and 1 method based on time in the air (JUMPAIR). All 4 methods showed excellent reliability (R > 0.97). Using VJPT as the criterion, the other 3 methods showed excellent coefficients of validity (R > 0.95) but poor accuracy: The obtained vertical jump height scores were statistically different among all methods (p < 0.01). JUMPAIR is considered a relatively simple and inexpensive method to obtain valid and reliable measures of vertical jump performance without an arm swing, provided the appropriate adjustments are made to the jump results. ----------------------- Dr Mel C Siff Denver, USA Quote Link to comment Share on other sites More sharing options...
