Relative strength (RS) was calculated for each athlete with the following equation: (kilograms lifted) / (body . The cross over hop had high predictive validity, similar to the 6m timed hop test. In fact, one study found police recruits with the lowest vertical jump in their cohort had a 37% absolute increase (or a three-fold relative increase) in risk of injury.22 While the SLVJ and the Keiser are capable of measuring explosive leg power, they are mechanistically different and do not produce identical BAI as shown in this study. As an injury predictor, leg power is accurately measured with the Keiser Air420 seated leg press.Purpose: To measure and analyze lower leg asymmetry in healthy collegiate athletes across each test battery.Methods: Eighty-eight healthy student-athletes (44 males, 44 females) across 14 varsity teams at Wake Forest University performed the SLHD, SLVJ, and the Keiser. The seat was positioned so that 90 knee flexion was obtained. Use our testing guide to conducting, recording, and interpreting fitness tests. That is, the height of the jumper's c.m. Am J Sports Med. They could take as long as they needed between trials. Objectives: Perform an appropriate warm-up. 24. The KOOS Sports and Recreation subscore was weakly correlated with the triple hop test (0.2) and single hop test (0.2). Prior to starting, each participants height (cm), weight (kg), and age were recorded into the Keiser interface, and the participant was then instructed on how to operate the Keiser leg press. 2017;12(1):e0170627.
