I agree the footsteps are very similar to walking or running motion. But I used to compare it with riding a horse, sitting on a saddle with your feet out on the stirrups. The close stance forehand of Rune, in the option, there’s two situation: 1. When the left leg just almost landing, your left joint should be extended, the thigh is twisted clockwise from the perspective of player. When you land, body weight is just shifted from back to front leg, then you twist the front leg thigh anti-clockwise, your left hip joint flex,your right arm firing foreward. 2. When the front leg land on ground too long, and you are MISSING the momentum of body weight shift from back to front, all you can do is rotate your right hip a bit clockwise, then immediately the front leg thigh will retain its momentum to twist anti-clockwise, the left hip joint flex, then fire the right arm forward. It always happen when distance between front and back legs are too short. Many people think “back kick”generate power, actually it’s not. It only helps to put back stored energy to your front leg. When your front leg release the power, the opposite arm explode! Anyway, left leg right arm, right leg left arm. One hip joints in extend, other in flex. I think it’s complicated but actually very simple and logical.
＞When your front leg release the power, the opposite arm explode! Yes, that's unquestionably true!!!!!! and･･･many people (and me)think that the triggering movement to create the situation is the work of the backfoot,I guess. In Japan, the word “backfoot” has been seen quite often. How is it where you live? I really appreciate your deep comments.
@@teikyu-funny.squarethe biggest problems are we can’t use our eye to find out how a players body motion mechanics is. Roger Federer looks like he is pushing up his right leg in open stance forehand, but I think it’s just a side effect. Secondly, people see things from their perception rather than the truth. They think it works in that way, then what they saw becomes that way. Most people push right legs when doing forehand, back kick in two hand backhand. It’s a human instinct and daily lives experience, they don’t know too much about their body. Backkick is working in certain situations. Roger Federer is a real genius and chosen by god to play tennis. I study him, using my knowledge in martial arts and other sports and physics…… Believe in me what he did is out of peoples mind. So different and innovative. His footwork and power generation are same as Chinese martial art Tai chi. His arm work is perfectly aligned with mechanics theory. His last action before contact the ball, there’s a theory discovered in outer space can explained it. Human muscle contraction cannot make a ball spin at 5000 rpm with such body motion.They must be something else.
To really understand Federer, (not play like him, I think only young kids maybe possible) we need to answer a few questions: 1. Why the lateral hop happens in forehand wide ball? 2. Why his forearm and upper arm maintain approximately 90 degree. 3. Why his neck bend to right doing forehand? 4. Why his left arm not extend out like others in backhand? 5. Why his eyes looks like stay at the ball before ball contact? 6. Why his backhand slide can comes down almost vertically? 7. What make him so good at no-look-overhead forehand with his back facing his opponent? 8.what makes his racket head so dynamic right before ball contact.
I think Federer is a divinely chosen tennis player, but I also have a lot of respect for the research you're doing. Amazing, that's a really deep analysis. It's going to be difficult for tennis players to do these, but I think it's just as difficult for coaches to fully verbalize your 8 questions.
@@teikyu-funny.square I remember you have a video showing 3 Federer forehands motion side by side, all their take back timing is the same. It’s amazing. I felt so much watching this video. It took me a long time to learn this but still will shank the racket sometimes. Imagine you don’t have any muscle contraction and the forward motion is totally driven from your body motion. First you have to fight your unconsciousness, not to muscle your arm to hit the ball. It’s a very very difficult job. Secondly, when you can stop muscle contraction, the eye/arm coordination by your bran to help you address the ball NO LONGER working. That means you have to keep your eye on the ball, for example, when the ball reaches a point is 20cm before bounce on ground, you have to land your right feet final step on the right spot and start the backswing. Once the backswing is start, it is a point of no return, your swing path is fixed and you can no longer change it. Your right feet land on a wrong spot, you will miss the ball. The backswing timing is wrong, you will miss the ball. Imagine how painful it is for an adult to give up his habit and learn this. Almost impossible. By the way, I study Federer is for teaching my 11 years old son. He ask me if there’s a way to swing the ball without effort. I said yes, but every stroke you need to prepare 10 things before hit the ball. But the ball will fly and spin wherever you want it to be.
We don’t 捻 on ground, we push on ground. That 捻is probably coming from ridding a horse, your foot stepping on a stirrup the you will 捻。different is your are holding a racket not a weapon.
