Vertical Jump Contributions from Hips, Legs & Ankles?

[Chas Tennis]

Don't try jumping in an unusual way. I did and it felt risky to the back.

The part played by the jump in the serve is often discussed. The part played by the 'legs' is usually associated with the jump and often discussed on the forum. But the hips also play a less obvious and discussed part in the jump and in other tennis motions.

I look at knee bend for the serve. But I don't study the hip angles and the part they play in tennis strokes and especially the jump on the serve.

I searched the subject of the standing high jump and started finding some interesting stuff.

If you have any information on jumping or jumping for the serve, forehand or other tennis strokes, please post.

Hips seem to help torso rotation only not the jump. No?

Quoting from the link on the the standing high jump

"The basic idea is the vert is mainly a combination of ankle extension (calf), knee extension (quadricep), and hip extension (glutes). Individual joint contribution to a typical standing bilateral vert will be around 40% hip, 40% knee, and 20% ankle. HOWEVER, the degree of individual muscle/joint contribution can change somewhat based on the individual."

That's 40% hip and 40% knee. The article says that different percentages will be seen in jumping.

The standing high jump is different than the serve but that is what the thread is about.

Makes sense although I had difficulty grasping the role of glutes at first.
