Definition

Land soft and balanced — absorb through ankles-knees-hips with the knees tracking over the toes; a stiff or inward-collapsing landing is the main plyometric injury risk.

Detail

Sound landing mechanics are the single most important safety skill in plyometrics, jumping, and deceleration, and a poor landing is a primary mechanism of non-contact knee (ACL) injury. The goal is to dissipate large ground-reaction forces over a short, controlled range.

Key elements of a safe landing:

  • Soft, "quiet" landing: contact on the balls of the feet then settle through the whole foot, flexing ankles, knees, and hips to absorb force (a "give" into a partial squat) rather than landing on stiff, locked legs.
  • Knees over toes — no valgus: the knees must track in line with the toes; inward (valgus) collapse of the knees is the dangerous fault to eliminate. The gluteus medius/hip abductors control this.
  • Balanced and symmetrical: land with even weight, a braced trunk over the base, hips back, and the COM over the feet — "stick" the landing under control before progressing to reactive (fast-rebound) landings.
  • Eyes/trunk: head up, chest over the knees, no excessive forward trunk collapse or backward lean.

Teach landings before jumping height: master a controlled "stick" landing from low drops, screen for valgus/asymmetry (e.g., tuck-jump assessment), then progress to reactive landings with short contact times only once control is solid.

Key facts

  • Land soft/quiet, absorbing through ankle-knee-hip flexion (not stiff legs).
  • Knees track over toes — eliminate inward (valgus) collapse (key ACL mechanism).
  • Land balanced/symmetrical, hips back, braced trunk, COM over the feet.
  • Master controlled "stick" landings before fast reactive contacts.
  • Screen and correct landing faults (valgus, asymmetry) before progressing intensity.

Gluteus Medius
A fan-shaped hip abductor under the gluteus maximus, important for balance in walking.
Quadriceps
The four knee extensors — rectus femoris, vastus medialis, vastus lateralis, vastus intermedius (rectus femoris also flexes the hip); the leg-extension arc is ~90° (knee bent to straight).
Deceleration
The controlled, eccentric braking of body momentum — a trainable skill that limits change-of-direction speed and protects the knee when done well.
Depth Jump (Drop Jump)Closely related
Step off a box, land, and immediately rebound into a maximal jump — the highest-intensity plyometric and the classic reactive-strength drill.
Plyometric Prerequisites & Readiness CriteriaClosely related
Before high-intensity plyometrics, an athlete should have a base of strength, sound landing/balance technique, and (for lower-body work) the ability to squat a meaningful multiple of body weight.
Plyometrics (Definition)Closely related
Quick, powerful movements that use a rapid eccentric pre-stretch immediately followed by an explosive concentric action — training the stretch-shortening cycle to produce more power.
Knee–Toe Relationship Rule
In the squat, manage where the knees travel relative to the toes — keeping the knees from passing the toes versus keeping the spine vertical — and find the "happy medium."
Proper Form as Injury Prevention
Proper form is an injury-prevention measure — especially in squats, deadlifts, and the bench press — and form-breaking advanced systems are not recommended for beginners.
