Instruction and Jump-Landing Kinematics in College-Aged Female Athletes Over Time

Instruction and jump-landing kinematics in college-aged female athletes over time.

CONTEXT Instruction can be used to alter the biomechanical movement patterns associated with anterior cruciate ligament (ACL) injuries. OBJECTIVE To determine the effects of instruction through combination (self and expert) feedback or self-feedback on lower extremity kinematics during the box-drop-jump task, running-stop-jump task, and sidestep-cutting maneuver over time in college-aged fema...

Immediate effects of real-time feedback on jump-landing kinematics.

STUDY DESIGN Randomized controlled trial. OBJECTIVE To determine if the addition of real-time feedback (RTF) to postresponse feedback (PRF) improves jump-landing kinematics compared to PRF alone and a no-feedback control group. BACKGROUND Injury-prevention programs to reduce risk of anterior cruciate ligament injury have shown promising results in altering jump-landing biomechanics. Real-ti...

The Effects of Instruction on Landing Strategies in Female College-Aged Dancers and Non-Dancers: A Pilot Study

Modifying spike jump landing biomechanics in female adolescent volleyball athletes using video and verbal feedback.

Landing awkwardly from a jump is a common mechanism of injury for the anterior cruciate ligament (ACL) of the knee. Augmented feedback, such as verbal or visual instruction, has been shown to cause an immediate, positive change in landing biomechanics in a laboratory setting. No data exist on the longer term effects of feedback on jump landing biomechanics in a sports-specific setting. The purp...

Effects of jump and balance training on knee kinematics and electromyography of female basketball athletes during a single limb drop landing: pre-post intervention study

BACKGROUND Some research studies have investigated the effects of anterior cruciate ligament (ACL) injury prevention programs on knee kinematics during landing tasks; however the results were different among the studies. Even though tibial rotation is usually observed at the time of ACL injury, the effects of training programs for knee kinematics in the horizontal plane have not yet been analyz...
