Abstract
It is well established that female athletes have a greater incidence of lower extremity injuries when compared to males of the same sport. There is interest in using the depth jump as a practical screen for lower extremity injury risk, however, prior research is inconclusive. There is evidence that males and females tend to adopt distinct motor strategies when anticipating and reacting to the landing impact phase of depth jumping. From this, it is reasonable to expect that depth jump kinetics are influenced by sex, yet there is a need for comprehensive analysis. Gaining a better understanding of which kinetic variables are most specific and sensitive to sex could improve the efficacy of using the depth jump as an injury risk screen. Thus, the purpose of this investigation was to evaluate the sensitivity and specificity of sex for detecting differences in the kinetics of depth jumps performed by NCAA Division I basketball athletes. Twenty NCAA Division I basketball athletes (male n = 9, female n = 11; 19.9 ± 1.1 years; 82.6 ± 13.9 kg; 188.6 ± 11.3 cm) volunteered to participate in this investigation. Participants performed 3 trials of depth jumping from drop heights of 0.51, 0.66, and 0.81m. For each trial, vertical ground reaction Forces were captured using a tri-axial Force platform. Dependent measures were estimated from Force data and included peak Force, rate of Force development, peak Force reduction, jump height, ground contact time, and the reactive strength index. The sensitivity and specificity of sex for detecting differences in dependent measures were evaluated using receiver operating curve analyses. The area under the curve for dependent measures ranged from 0.51 to 0.98. The area under the curve for jump height (0.81m DJ) was statistically significant (p < 0.001). The area under the curve for all other dependent measures was not statistically significant (p =0.08 – 1.00). Although the sample size in the present investigation was not sufficient for detecting variable specificity and sensitivity to sex, the findings may support further research and application of the depth jump as a tool to screen for lower extremity injury risk in competitive athletes. Presentation Time: Thursday, 9-10 a.m.
