Scissor Kick Forehand?
 
Does anyone know who first invented/popularized this technique? Aside from handling high balls, are there other benefits to hitting a scissor kick forehand? I've read that it generates a lot of torque, but my understanding of physics isn't that great. Is this the same thing as saying that the opposing rotation of the hips increases the whipping around of the torso? If so, how much power does this technique add?

Form follows function.

I've heard of scissor kick on an overhead but I don't think there even is such thing as a scissor kick forehand. Perhaps you are referring to a jumping forehand? Post a link to a video where you have seen such a thing demonstrated.

Not sure what you mean, but I do do something funny with my feet on certain high ball when I'm going down the line. I'm not sure it's a scissor kick, though.

Cristophe has a good video about the "scissor-kick" FH here:

Here's a clip where various pros hit it:

I think it must be a modern technique since it is hit from an open stance and it uses the idea of torque and angular momentum as opposed to linear momentum. So I'm guessing that somebody "invented" it post-Borg but I don't know enough tennis history to know when it first appeared.

I see, it really isn't a particular technique or something you need to learn. It is just a jumping forehand where you naturally torque lower body to create the effect of a closed stance for an inside out forehand from the backhand corner or a down the line forehand from the forehand side.

the purpose of this is to decelerate hip and spine rotation before contact so that the energy goes into the arm.

when you hit with the leg on the ground you don't need to do that since the ground anchors you and allows for deceleration but in the air you have no anchor and thus kick the foot back a little when doing a jumping FH.

also seen in a 2HBH.

Funny you mention this saw a documentary on Agassi the other night and he hit this very shot on a service return so I would look at some tape from his matches

Jump into the air and Scissor Kick legs action force the hips clockwise rotation. According to the Law of Momentum Conservation upper body has to start rotation in opposite direction counterclockwise. So, upper body rotates faster in case of jump FH with Scissor Kick than just jump FH. IMO, this technique can add less than 10% to the RHS because upper body rotation is relatively slow.:confused:

Thanks for the responses. It's interesting to get a better technical understanding of what's happening. As a guy that stands 5'3" tall, I may give this technique a try the next time I'm on the court.
