The purpose of the study was to assess the contribution of upper leg length (ULL) and lower leg length (LLL) to leg power (LP) and vertical jump (VJ) measurements. Male (n = 11) and female (n = 15) students completed three trials of VJ and LP tests. ULL was measured from humeral trochanter to knee joint line; LLL was measured from knee joint line to lateral malleolus. VJ was measured with a Vertec. A modified Smith machine with an attached accelerometer was used to measure LP. LP was determined from a supine by kicking the bar as high as possible. Reliability for leg dimensions and performances were high (ICC>0.974). Correlations between leg lengths and VJ and LP were not significant in either gender. These results suggested that leg length have little influence of ability to perform jump and power maneuvers in either men or women.
