Physical explanation on NEW FOUND POWER: Lift when you extend contact

[ho]

On Hi-tech.com (excellent site) Jeff and Mr Doug King have said on a new new found power : Lift when you hold. I feel like i should have an insight math physic to explain that, and hope will contribute to Jeff and Doug for great jobs that they do.
accelerate horizontal when you hold create power, but not as much as you accelerate, hold and lift. As i state last week speed of the ball depends on time you hold and acceleration. Hold the ball horizontal do not have a lot of time as holding in vertial, due to gravity. And second more, acceleration in angle, can developed in 2 components: vertical and horizontal. It obvious that acceleration while lift is greater than horizontal. You may argue that acceleration horizontal is more than sloped acceleration. Sorry, not true. When you accelarte when you lift, you use more help from different muscle that you use when you do horizontally. More time, more acceleration, more muscle, that my humble explanation for the new found power that Doug and Jeff have contribute so much for the game.
I also take this opportunity to express my displeasure with the way this forum goes. Here is the place that we like discussion on tennis matters and learn, not a place to humiliate each other like uneducated thugs. Knowlege along with ethic contribute. Knowlege along with unethical behavior destroy.
Tennis Warehouse staff should do a better job of controlling these thugs. We or at least me do not need them , it's the people like Jeff and Doug that make we come here. After all UFC (unlimited fighting in the cage) is more interesting than TFC (tennis fighting in the cage).
Even i know that most people in this society will disagee with me. But i do my last stand.

What he said.

I think (my translation) is to swing at an angle so you can swing faster? Or perhaps it's sit and lift. He said lift a lot....

WTF dude??, WTF!!
oh, i did like your "After all UFC (unlimited fighting in the cage) is more interesting than TFC (tennis fighting in the cage)" analogy, ground and pound is where its at
but as far as your message goes, WTF man, say it in spanish if english is hard for you, works for me all datime

I guess what its mean is hold your racket like this / instead of \, cause that how i play and im the first to discover that and been playing like that since 2 years ago. I dont know what this post is talking about but to me, i lift up the ball (more like the racket hit the ball like this o/ instead of o\) like how you kicking the soccer ball with your leg, to me its give more deadly spin (like the speghitti string or so) and depending on your stroke will make the ball prenetrate. Will try to see if i can post up a video clip of how i hit with crazy spin, but the thing is how to post up video clip in here.

Ho, last week you said that length of time of contact between ball and racquet is a factor in the speed of the return shot. In other words, the longer the strings are touching the ball, the longer time you have to accelerate the ball. Now I think are you saying that by lifting while hitting, that allows more acceleration because of increase in time? Or increase in distance?

The forehand is still coming forward at the same speed regardless of whether you lift with your legs, but when you lift you add extra distance because the line of travel during contact is moving at an angle and not just a straight horizontal line. The horizontal distance is still the same, but the distance traveled during contact is greater by the vertical lift. Does that add acceleration if the time of contact and horizontal distance is the same?

Again, I don't think you have to understand the precise mechanics of tennis in order to play it well. Also, don't forget that it's not legal to deliberately carry a ball on your racquet.

Sit and lift is an "old power" source. He said new. I guess it was "lost in translation."
