    HAHAHAHA, yes, and the eyes can process the incoming ball with exceptional detail to see it hit the strings despite what scientific studies show us and people in the know tell us.

    Yeah, I know. It is brainless babble. ;)

    Sort of. There have been many tests to see how fast a sensory response gets sent to the brain. We have the science and equipment to measure how fast the brain receives information from the touch or feel of something.

    These arent "things" that are pulled out of our ars. There is a lot of science behind vision therapy, training, and vision itself. We know a lot more than we do now and some things dont need further evidence and become the basis of new learning and research.

    First, the eyes can not physically move fast enough to process detailed information to the brain when a ball is within 4 - 5 feet of the player. By the time the eyes try to see the detail, the ball has already hit the strings and is headed back to the opponent.

    Obviously, this depends on how fast the ball is going. If the ball is moving very very slow, the eyes can keep up and provide the brain the sensory input handle the detail.

    This is a very simple thing to learn which is why you waiting for "more proof" is a bit absurd.

    Wave your hand in front of it and try to follow your hand. Wave it very slow and then very fast. This is what has been studied. The eyes can not keep up with a simple hand movement as it speeds up. The hand blurs.

    Now, some humans wil have better eye sight but you then have to divide the better vision they have into the categories that vision has been defined.

    However, in the end, when an object is close, small, and moving fast, the eyes can not move fast enough to process the information in detail.

    YOU ARE LEGALLY BLLIND WHEN THE BALL IS WITHIN 4 - 5 feet and the ball blurs.

    True, and I can count the times when we discover something, define it and use it as a basis to learn new things. I think gravity is one of those things. When we discover something from a physics perspective, we learn how to define our world. Eye movement, the size of the object, how fast the object is moving, and how close it is to the subject are things that is staple knowledge.

    I dont know how you can dismiss what has been tested and shown to be true. Do you still dismiss that the earth revolves around the sun?

    Uh, haven't we said all of this just a day or two ago?

    Couple thoughts:

    Take a look at BB's posts. I want you to REALLY look at them, meaning the quality of information and/or the amount of detail he goes into with every post. Now I want you to ask yourself, "could it MAYBE be possible that this guy's the real deal"?

    After you've done this, take a look at some of your posts. Do you perceive them as: more mature, less, somewhere in between? And how does the information and more importantly, the PRESENTATION of it compare to Bill's? Is it: more or less organized? Do you: frequently jump to conclusions that he has to clear up for you?

    And so on.

    I never said he never finishes over the shoulder. What are you talking about?

    I said on a standard Nadal forehand he finishes in the torso area, i.e. below the shoulder. BB posted a picture of Nadal in an extreme situation far behind the baseline with both feet off the ground. He then went on to say that I was wrong because he finishes over his head and shoulder often.

    Never once did I contradict this. I said on a standard forehand, meaning when balance, legs, and ball are all in optimal position, Rafael Nadal finishes below the shoulder. This isn't hard to understand, and was further confirmed by the videos I posted.

    But the discussion that I began with another poster, and you and BB decided to enter, was entirely a superficial argument. We were specifically talking about finishes.

    And? So what? I was talking about the finish. It was entirely important because that was our conversation before you decided to butt in. What you're talking about has NOTHING to do with what I was talking about. I was, indeed, talking about superficial matters.

    Excuse me? This has NOTHING to do with that guy. I was talking to another poster. Read posts #385 and #386. I never once said Nadal always finishes around the torso nor did I say he never finishes over his head or over his shoulder.

    I responded to a poster who said that both Nadal and Federer finish over their shoulders. He was speaking about their normal, standard forehands.

    Honestly boy, you've got a lot of nerve talking to me about maturity. A) You have nothing to do with this conversation as you don't even know how it started. I wasn't talking to you. B) You use BB language like "Einstein. It's embarrassing.

    It's downright comical how little you know about which you're talking. I was speaking specifically about superficial matters, i.e. where the racquet finishes. I was responding to another poster, i.e. not you or BB.

    It sounds like, instead of trying to win an argument, you need to actually read. Try posts #385 and #386. If you find something false in what I said, then quote it.

    For you students out there, this is what is called a "straw man argument".

    Notice in my first post I didn't exclude the possibility that "on many shots Nadal does finish over his shoulder". I said on a "standard forehand". He says "actually" to insinuate he's contradicting me, when I, in fact, never said that Nadal doesn't finish over his shoulder or over his head.

    On a standard forehand, when Nadal is in position, balanced, and the ball is at optimal height, Nadal's racquet will end up around the torso area.

    Bungalow Bill is the unequivocal King of the Straw Men, and his lackey, Djokovicfan4life, follows not far behind, nibbling on his scraps.

    So what is a standard forehand for Nadal? And are you leaving it open for your "torso" word also so you cant fail? Here you go Einstein! LOL!

    http://www.youtube.com/watch?v=CkWiiuYmFqU&feature=related

    Seems to me the hand is up around shoulder area. But wait, dont let me put words in your mouth. LOL!


    Yeah, I am the king. LOL!

    Except Nadal's standard forehand IS the reverse forehand, especially on clay and slower surfaces. So you're logic is shot again.


    http://vimeo.com/1552633


    Roughly 70% of Nadal's forehands are reverse forehands, whether he is balanced or not. Nadal rarely uses the standarad forehand, unless he plans on attacking and driving through the ball alot.

    He will say that the arm magically teleports below the shoulder, just like how Federer can use his cybernetic eye in order to see an event that happens within millionths of a second.


    I mean seriously BB, didn't you know. If you can see light, which travels faster than anything known to man, that must mean you are able to track the light particles too! :D :D :D - Example of storm's logic, if you see it, even if it is a mirage or illusion, it must exist.

    Haven't been able to read all the posts here, but here is my 2 cents. First, I think "windshield wiper" is a nice term because it accurately describes the path the racket takes in the pro forehand. The strings of the racket face the net as the entire arm goes through and up the back of the ball and then rotates over.

    The obviously problem with the term is that you have to tease out cause and effect (a problem John Yandell has addressed from day one). My personal conclusion, which I wrote about on tennisplayer.net, is that the wiper forehand comes from engaging the shoulder, which pushes the arm and racket through as it lifts up, and then rotates over.

    The big problem you run into is if you just "roll" the racket over the ball. This doesn't work because you aren't driving through and up and then over - just slapping or rolling across the body. When players finish with the elbow in close to the body, you know they haven't extended through the ball.

    So I think there are dangers to a superficial understanding of the "windshield wiper" phrase. It obviously doesn't capture the linear, forward motion through contact, but it does capture the idea of arm rotation - which is to me the big advancement in forehand technique. Rather than just hitting through the ball and extending forward, you add in the rotation of the hitting structure and get more powerful moves and added topspin.

    You can't find a modern forehand today without SOME rotation from the shoulder. Sometimes it is extreme with the full wiper path. Sometimes it is mild rotation. But rotation of the arm is going to be there along with the essential linear motion through contact.

    Spin it? Like you spun my original post?

    Perhaps you're slow (okay, we know you're slow), but you spun my original post to mean that Nadal never finishes over his head. Perhaps you'd like to respond to that. Maybe then I'll address your other questions. If you expect me to sit back while you lie about my posts but then oblige yours then you're mistaken, "coach".

    What does this mean exactly? Are you implying that a) you know what I look like and that b) you find me unattractive?

    He didn't spin anything. You said when Nadal hits a standard forehand, he follows through across his body and underneath his shoulder. However; Nadal's "standard" forehand is not that type of forehand. His standard forehand is the reverse forehand, which he roughly hits 70% of the time (about 80% on clay).


    Also, you stated with optimal positioning, Nadal hits the "across the body" forehand. However, that's not true. Nadal will usually hit his reverse forehand in that situation, UNLESS he is going for a winner, or going to approach the net.

    I respectfully disagree.

    Nadal hits a lot of different forehands, and he plays the shot with the higher finish as a more defensive and safer shot, but in my opinion his standard shot goes across his body.

    http://www.youtube.com/watch?v=ZmolgoM4p-I

    Here he is practicing his forehand. Why would he hit it across the body almost exclusively if this weren't his standard shot? Only at the end when he is pushed a bit out of position does he finish over his head, and it only happens once. Is he just having fun? Messing around?

    Because he's trying to hit a flatter ball. Duh.

    Still being childish I see.

    My point was only about his finish. In my opinion, his standard forehand (whatever standard means to me) is a shot straight across his body, ending below the shoulder.

    By the way, a lower finish doesn't necessarily mean flatter. Sampras finished high all the time and hit a pretty flat ball. Federer finishes quite low and hits with more topspin than Sampras. There are a lot of factors involved.

    This hinges on what we are calling standard. Nadal hits ALOT more reverse forehands than the normal forehands. If we're saying standard is what stroke he uses more, he typically uses the reverse forehand finish more, especially on clay.


    If you mean standard as in the "normal forehand" yes, you can call that wrap around his "standard" forehand I guess. Although it would be ambiguous to some, which is why I say his reverse forehand is his standard forehand, and the "normal" forehand is his finishing forehand.

    He doesn't understand that what the pros do up until contact determines the finish, which in itself means nothing.

    Of course I do. I already stated that I did in an earlier post, and that I was only referring to his finish.

    Why do you insist on repeating this crap?

    If you want, you can quote any post I made that demonstrates otherwise. If you can't, then, once again, you're just talking smack, which is about all you're good for, other than being Bungalow Bill's "bungalow boy".
