The purpose of this study was to examine the relationship between bilateral countermovement jump (bCMJ) asymmetry and asymmetries in lower extremity flexibility, anthropometry, strength and single leg jump performance. Three criteria were identified for each of these attributes. Thresholds were determined to diagnose asymmetry in all criteria based on exceeding the mean ± sd of the absolute difference between limbs. A total of 145 subjects across a variety of sports were tested. The overall agreement in diagnoses compared to bCMJ were 49.7% flexibility, 58.6% anthropometry, 66.9% strength and 70.3% single leg jumps. Individual attributes had associations of between 27.5-32.5% with actual bCMJ asymmetries and this rose to 72.5% when all attributes were combined. 82.9% of subjects possessed at least one lower extremity asymmetry.Downloads
