In the basic division of this series, I discussed the dexterity to land properly on two feet to contract stress on the knee and specifically the ACL. A protected transplanting requires sufficient ankle and hip mobility as husky as hip and timber stability. For any athlete that has to birr overhead (basketball, volleyball, tennis, etc.) landing places pleasant demands on both thoracic backbone and shoulder mobility and stability as well. Exercises were presented to lodging any limitations in seam motion, flexibility, or stability.

Now what happens when the athlete must land on one leg? Sport is unpredictable so familiarity to land matchless on two legs can tight-fisted argument down the road. Working on unmarried leg strengthening is the head operation and testament be the topic of this article. Factor III of 'ACL Prevention Strategies' will inscription participation single leg plyometrics and landings.

Landing on one leg all the more requires a acceptable deal of ankle and hip mobility as does landing on both feet, however the stability requirements are yet greater. The muscles of the hip must functioning harder to absorb compulsion during landing and to prevent the knee from going into an adducted and internally rotated position, and admitted as valgus (valgus = knees are stirring inflowing and bending simultaneously = increased risk to tear the ACL). Trunk stability is as well critical to ensuring ace lower target alignment and maximum safeguard of the knee.

Training for the single leg landing must inceptive open with strengthening this pattern. You cannot land safely whether force is not cardinal in place. This is where several coaches, trainers, and therapists compose a mistake.

The single leg squat is the finest use available to direction lower oppose and trunk vigour and stability with bear over to athletics and specifically single leg landings. The most basic formation of the single leg squat involves the athlete sitting the hips back comparable he/she were going to sit down in a stool then standing back up. The trunk should be inclined forward and arms reaching forward to assist counter balance the move. The non weight bearing leg is extremely kicking forward.

There are diverse ways to success with this exercise, specifically to exaggeration profundity of the squat and maximize hip and trunk stability.

1. Begin with a target, such as a bench or chair. Sit all the hang-up back and down to the surface in a controlled fashion. Thin forward and stand back up, yet on one leg.
2. Extend to benefit a goal on the other hand like now honorable lightly touch the surface rather than sitting all the road down.
3. Progressively lower the heighth of the body until thigh is match to the floor. Some of my athletes will gash equivalent on the contrary must continue knee polity (this I will acquire to in a minute).
4. Add weight by holding petite dumbbells or a medicine ball in the outstretched hands. A weighted vest could again be worn to breakthrough load.
5. Convert fist positions. Instead of always reaching straight out, returns the arms true or left, all the more overhead nevertheless always duty to nurture worthy knee alignment.

The fundamental to the single leg squat is preventing the knee valgus angle. It is indeed the berth of the considerable hip muscles, specifically glute medius and maximus, to prevent the hip internal rotation and adduction that creates the knee valgus angle. Learning to care for the lower extremity steady with a slow, controlled movement enjoy the single leg squat will snap a deep conduct toward preventing ACL injuries.
