| Knee and Thigh motion |
1. Lower Extremity valgus at landing |
Frontal (F) |
No valgus |
Slight Valgus |
Obvious valgus: Both knees touch |
| 2. Thighs do not reach parallel (peak of jump) |
Lateral (L) |
The knees are higher or at the same level as the hips |
The middle of the knees are at a lower level than the middle of the hips |
The whole knees are under the entire hips |
| 3. Thighs not equal side-to-side during flight |
F |
Thighs equal side-to-side |
Thighs slightly unequal side-to-side |
Thighs completely unequal side-to-side (one knee is over the other) |
Foot Position
During Landing |
4. Foot placement not shoulder width apart |
F |
Foot placement exactly shoulder width apart |
Foot placement mostly shoulder width apart |
Both feet fully together and touch at landing |
| 5. Foot placement not parallel (front to back) |
L |
Foot (the end of the feet) placement parallel |
Foot placement mostly parallel |
Foot placement obviously unparalleled (one foot is over half the distance of the other foot/leg) |
| 6. Foot contact timing not equal (Asymmetrical landing) |
F |
Foot contact timing equal side-to-side |
Foot contact timing slightly unequal |
Foot contact timing completely unequal |
| 7. Excessive landing contact noise |
F/L |
Subtle noise at landing (landing on the balls of their feet) |
Audible noise at landing (heels almost touch the ground at landing) |
Loud and pronounced noise at landing (contact of the entire foot and heel on the ground between jumps) |
Plyometric
Technique |
8. Pause between jumps |
F/L |
Reactive and reflex jumps |
Small pause between jumps |
Large pause between jumps (or double contact between jumps) |
| 9. Technique declines prior 10 seconds |
F/L |
No decline in technique. |
Technique declines after five seconds |
Technique declines before five seconds |
| 10. Does not land in same foot print (Consistent point of landing) |
F/L |
Lands in same footprint |
Does not land in same footprint, but inside the shape |
Lands outside the shape |
