Prescriptive Verbal Cues and Their Immediate Effect on Jump-Landing Techniquea
Study |
Cue |
Focus of Attention |
Result |
Cowling et al43 (2003) | “Land with your knee bending” | Internal | Reduced peak GRFs compared with baseline and other condition |
“Turn the muscles at the back of your thigh on earlier and more before landing” | Internal | Increased peak GRF compared with baseline and other condition | |
Favre et al44 (2016) | “Land softly” and “increase knee flexion angle during landing after the block jump” | External and internal | Increased knee-flexion and -adduction angles |
Reduced knee-flexion and -adduction moments | |||
Reduced vertical GRFs | |||
Khuu et al36 (2015) | “Reduce contact time” | External | Decreased sagittal-plane hip, knee, and ankle range of motion throughout ground contact time compared with other conditions |
Decreased frontal-plane knee motion compared with other conditions | |||
Increased vertical GRFs, vertical stiffness compared with other conditions | |||
Decreased knee-abduction angle compared with other conditions | |||
“Maximize jump height” | External | No difference between triple-extend cue | |
“Triple-extend the hips, knees, and ankles when jumping” | Internal | No difference between cues | |
Milner et al18 (2012) | “Land softly” | External | Decreased vertical GRFsb |
Increased peak knee-flexion anglec | |||
“Knees over toes” | Internal | Increased peak knee-flexion angle | |
“Equal weight distribution on both your feet” | Internal | Decreased vertical GRFs | |
Increased peak knee-flexion anglec | |||
Wernli et al42 (2016) | “Land quieter” | External | Increased ankle and knee excursion compared with baseline |
“Land louder” | External | Decreased ankle excursion and increased hip excursion |
Abbreviation: GRF, ground reaction force.
Includes those studies that only used prescriptive verbal information.
Greater than “knees over toes” and “equal weight distribution on both your feet.”
Greater than “knees over toes.”
