Increased Leap Performance With No Change to Knee-Drop Landing Kinetics, Following a Verbal Cueing Intervention

Area of Science:

• Biomechanics
• Dance Science
• Motor Control

Background:

• Knee-drop landings in contemporary dance are common but biomechanically understudied.
• Limited research exists on optimizing these landings for performance and injury prevention.

Purpose of the Study:

• To investigate the effect of verbal cueing on the performance and kinetics of knee-drop landings in contemporary dance.
• To assess if cueing improves jump height and flight time without increasing musculoskeletal loading.

Main Methods:

• A quasi-experimental design with 8 pre-vocational dance students.
• 3D motion capture and force plates were used to collect kinematic and kinetic data.
• Data collected pre and post a verbal cueing intervention during a dance leap and knee-drop landing.

Main Results:

• Statistically significant increases in jump height and flight time were observed post-intervention.
• No significant differences were found in peak vertical ground reaction forces (vGRFs) or loading rates before and after the intervention.
• The intervention optimized performance without adverse effects on landing impact forces.

Conclusions:

• Verbal cueing effectively enhanced dance leap performance (jump height, flight time) without increasing detrimental landing forces.
• The findings suggest a positive influence of cueing on dance execution and musculoskeletal loading.
• Caution is advised due to the small sample size and lack of a control group, limiting generalizability.
