Abstract:
BACKGROUND:Evaluation of vertical jumping ability is usual y only limited to height measurements. The measurements of parameters that describe kinetic factors may provide a better assessment of a patient’s jumping ability.
OBJECTIVE:To determine the deficit in one-legged vertical jumping ability and to clarify the relationships between the maximum jumping height and the maximum power, force and velocity during one-legged vertical jumps after anterior cruciate ligament reconstruction.
METHODS:Twenty-five healthy subjects (10 males and 15 females) and 25 anterior cruciate ligament reconstructed patients (10 males and 15 females) participated in this study. The isokinetic quadriceps femoris strength and one-legged vertical jumping ability were evaluated by the height, power, force and velocity in al subjects.
RESULTS AND CONCLUSION:(1) The maximum height of the one-legged vertical jumps was only significantly correlated with the maximum force in the healthy subjects (P<0.05). (2) However, for the reconstructed and unreconstructed legs in anterior cruciate ligament reconstructed patients, the maximum jumping height was significantly correlated with the maximum power, force and velocity during one-legged vertical jumps (P<0.05). (3) These findings suggest the importance of a knee strategy during one-legged vertical jumps for rehabilitation after anterior cruciate ligament reconstruction. Assessment of the jumping ability after anterior cruciate ligament reconstruction may be determined by the maximum power instead of the maximum jumping height.
