Abstract

PURPOSE To determine between-limbs differences in isometric rate of force development (RFD) measured during open- (OKC) and closed-kinetic-chain (CKC) strength testing and establish which method had the strongest relationship to single-leg vertical-jump performance and knee mechanics after anterior cruciate ligament (ACL) reconstruction. METHODS Subjects (n = 19) 1 to 5 years from ACL reconstruction performed isometric knee extensions (OKC), unilateral isometric midthigh pulls (CKC), and single-leg vertical jumps on the ACL-involved and -noninvolved limbs. Between-limbs differences were assessed using paired t tests, and the relationship between RFD, jump performance, and knee mechanics was assessed using correlation coefficients (r; P ≤ .05). RESULTS There were significant between-limbs differences in OKC RFD (P = .008, d = -0.69) but not CKC RFD. OKC RFD in the ACL-involved limb had a strong association with jump height (r = .64, P = .003), knee-joint power (r = .72, P < .001), and peak knee-flexion angle (r = .72, P = .001). CKC RFD in the ACL-involved limb had a strong association with jump height (r = .65, P = .004) and knee-joint power (r = .67, P = .002) but not peak knee-flexion angle (r = .40, P = .09). CONCLUSIONS While both OKC and CKC RFD were strongly related to jump performance and knee-joint power, OKC RFD was able to detect between-limbs RFD asymmetries and was strongly related to knee-joint kinematics. These findings indicate that isometric knee extension may be optimal for assessing RFD after ACL reconstruction.

前十字韧带重建术后开放式和封闭式动力学链的力量发展速度与跳跃成绩的关系。

目的确定在开放式（OKC）和封闭式动力链（CKC）力量测试中测得的等长力量发展速率（RFD）的肢间差异，并确定哪种方法与前十字韧带（ACL）重建后的单腿垂直跳跃成绩和膝关节力学关系最密切。方法受试者（n = 19）在前交叉韧带重建1至5年后分别进行了等长膝关节伸展（OKC）、单侧等长大腿中部牵拉（CKC）以及前交叉韧带受累肢体和非受累肢体的单腿垂直跳跃。使用配对 t 检验评估肢体间差异，使用相关系数 (r; P ≤ .05) 评估 RFD、跳跃成绩和膝关节力学之间的关系。结果OKC RFD 的肢体间差异显著（P = .008，d = -0.69），但 CKC RFD 的肢体间差异不显著。前交叉韧带受累肢体的 OKC RFD 与跳跃高度（r = .64，P = .003）、膝关节力量（r = .72，P < .001）和膝关节屈伸角度峰值（r = .72，P = .001）有密切联系。前交叉韧带受累肢体的 CKC RFD 与跳跃高度（r = .65，P = .004）和膝关节力量（r = .67，P = .002）密切相关，但与膝关节屈伸角度峰值（r = .40，P = .09）无关。这些研究结果表明，等长伸膝可能是评估前交叉韧带重建后RFD的最佳方法。
