Purpose: Mobility is a key component in the training of athletes. Being optimally mobile has proven to increase power and performance. In recent studies, being hypermobile increases the incidence of injuries in specific athletic populations. The purpose of this study is to find the ideal knee joint mobility for lower extremity performance. Methods: Twenty-nine healthy students (15 female, 14 male; mean age 21 ± 3 SD) were recruited from Bethel University in St. Paul, MN. Subjects completed an informed consent. Subjects’ knee joint angle was measured with a goniometer at lowest possible squat with heels remaining on the ground. Subjects were then tested using a triaxial accelerometer (Myotest SA) during the Counter Movement Jump (CMJ). Max Height (cm) was collected. Results: A Non-linear Regression Analysis was performed using SPSS. The data indicates no linear or curvilinear relation between non-active knee joint angle (mean 38.86 degrees ± 10.97 SD) and jump height (mean 36.10 cm ± 9.79 SD). Conclusion: Research has shown a quadratic relation to active knee joint angles during counter movement jumping activity. The current research demonstrates that there is no correlation with maximal knee joint angle not during activity and maximum jump height. This demonstrates the importance of analyzing knee joint angles during activity to individual knee joint angles for optimal training and performance.
