@blahness and others,
you need to observe just the millisecond of actual contact to get whats really going on. Ask yourselves if the ball can be affected when the bat is not in contact! About Timo saying "wraparound". does he say specifically WHY he wants the kid to wraparound? I would guess its for reasons of Transition and readiness for next shot. German speakers please help! Its a fundamental of good stroking that the racket angle should be constant through contact. Otherwise errors would result. The "wraparound" exhibited in yr Ma Long example is a function of Ma Long 's follow through which enables him to have good transition (to balance and readiness) by pulling the racket by folding his elbow. Also in this case the impression of "Wraparound" is exaggerated by his "hooking" the stroke to send the ball wider to the fh. But again this "Hook" does not involve changing the contact angle during the stroke it just means setting the angle before contact. Edited by pingpongpaddy - 04/11/2021 at 4:32am |

Actually he also curves the stroke path, it is not a straight line. It's easier to see it when it's hooking it, but in fact it is present in every single loop stroke. Watch closely below: |

again I would suggest you ask yourself how the ball can be affected by the stroke when not in contact! I wonder if the Flat Earth Society is looking for members? ![]() But seriously look no further than these ideas of yours for lack of progress in your game. Once you start to smell the coffee things will get better |

Umm, all of the super high level players I've played with teaches the wrapping of the ball. Even higher level players like Timo Boll, coach Meng from WRM table tennis channel (ex table tennis champion from China). I'm not sure how high level of a player you can be without understanding the wrapping of the ball. As you can see from the slowmo of Ma Long's loop, he closes the racket angle at contact.

you can refer to high level players all you want. In the end its what they do that counts not what they say. In watching yr video of ML i see him executing a quality closed racket contact without changing the angle during the contact phase. its worth remembering that not every high level player is also a high level analyst of tt technique whether his own or other peoples. Its worth remembering that the words you read or listen to may have been misinterpreted by you. On the other hand the video of ML represents the truth i am 72 i am no superstar, but back in the days before computer rankings I beat my national ranked no 23. During my career I have had the opportunity to converse with all kinds and levels of players and coaches and the consensus is that the stability of the wrist at the contact phase is vital otherwise errors result. Thus if the arm is swinging through contact at 46 degrees then the whippyness of the wrist should not be changed to 48 degrees. rather it should also be brushing at 46 degrees. Indeed I remember refusing to coach a promising junior because he had similar ideas to you. All the coaches agreed that he had a "wobble" in his stroke at vital moments causing errors but he wouldnt listen to us, so, in spite of his woderful bh he did not progress i watched the video . no wrap. no wobble. Just ML with his very simple excellent no frills technique with racket at same angle through stroke Edited by pingpongpaddy - 04/11/2021 at 6:09am |

No wonder, you come from the pre-inverted era which explains a lot.... wrapping is not very effective unless it's with modern inverted rubbers. That ML slowmo video is super clear imo, you can see that change in angle easily by him curving the stroke path. It is subtle (ie you have to look for it), but definitely there. Also wrapping the ball is extremely basic Chinese TT looping technique, all the tutorials teach that lol... How about this (watch from 3 mins onwards, and 6:50 onwards for coach Meng's demonstration)

when coach meng hits the ball for real his stroke is normal and stable. When he shadow strokes he demonstrates something like your theory his japanese mate is the same. He is unfortunately one of those coaches who has not considered that he is trying to teach something that he himself does not do in practice. its a pity because though his heart is in the right place his classes lead people like Blahness who dont have the habit of critically analysing incoming advice right up the garden path into error. Moral:: no matter who advises you, dont forget to use your own ability to think for yourself. here is a real coach. no bs no diagrams. just commonsense chinese olympic coach i played with inverted from 1960' to 1977- lp and tackiness up to 1979 then sp thereafter some tt history:- the modern style of playing with inverted began with hasegawa(1967) bengtssen (1971) when the heavier topspin briefly overcame the chinese sp hitting style of zhuang de dong. In 1977 the chinese recovered their dominance using lp play and looping play to be interrupted by the swedes later on. the first high performance inverted rubbers were sriver, super sriver and mark v which arrived about 1971- 72 btw I can recall doing that same practice that ML demonstrates 4 or 5 times a week with my practice partners in the early 70's. I would have been using mark v 2mm. There was no internet so we learnt the techniques from studying motion analysis photos from butterfly report. In those days we were loop crazy even more than today, partly because at the the time we saw the loop as something that overturned china dominance. We loved the round the net play of Jonyer and Gergely. However the the play of today shows that the fundamentals of tt tactics from china in the 60's - close to the table early striking have reasserted themselves in the advanced topspin of the 21st century we are starting to repeat ourselves. good luck in yr career Edited by pingpongpaddy - 04/11/2021 at 9:11am |

This video and another one posted on another thread are not talking about wrapping the ball. Those explain the Chinese drive-loop need more hitting through and the traditional spiny loop needs brushing/wrapping . By the way, Ma long is famous for its curve out topspin. His swing path is on another level : curving out rather than straight and curving in.

Actually it's neither of the both, before contacting the ball you have to go into it in a hitting movement to sink the ball reliably into the sponge (using the body), hence it will look like 2 pre-contact (but it's achieved with the body and not the arm), then after hitting the ball into the sponge then you need to wrap the ball to ensure max brush so it will look like 1 during and after contact, and it's achieved using pronation/supination... Zeio's diagram perfectly illustrates this.

1:The swing path of your racket combines all the movement of your leg, body, elbow, arms, wrist, finger, blade....
2: before contacting the ball you have to go into it in a hitting movement to sink the ball reliably into the sponge (using the body) Above is what exactly the 2 shows . Before contacting the ball there is a hitting movement 3:The traditional topspin/ loop is just what you talking about . We do see lots of wrapping loop in matches . Once a full speed hitting contact the ball and penetrate the sponge, the ball will be at its perk speed leaving your racket, the wrapping will barely have any impact.

Been held up by other stuff.
Posting the following just for now. Have quite a few other studies up my sleeve that will end the careers of some members here, especially the aspect of upward, forward, and lateral racket velocities. ![]() https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5950751/?tool=pmcentrez

GIVE UP ALL THE LOOPS . LEARN FORHAND DRIVES INSTEAD.
Japanese coach gave a new destroyer to ITO Mima hands, that is to drive the ball rather than looping. DRIVING the ball with a racket open face. This is the clue to Mima's super_power. Be happy. PS// Go and consult from Youtube video of Mima's training behind closed doors. |

Apologies if anyone is upset by my bringing this thread back to life. My 2 cents: The path traced by the center of the blade when looping, as viewed from the top and also from the side, IS curved, but that's just how the arm moves naturally. From the side view, the path will be more concave when the swing is shallower and more convex when the swing is steeper. Again, this happens naturally---it's how your shoulder joint and the rest of your arm move. It's detrimental to proactively effect a concave or convex swing shape. The swing shape is the combined effect of the upper arm swing, forearm and wrist movement, torso movement, direction of weight transfer, contact point on the ball, and direction of shot. Therefore, when discussing this topic, it's important to preface your comments/input by clarifying which component(s) you're talking about or whether you're referring to the whole. "Wrap" the ball with the overall swing shape is a different instruction from "wrap" the ball by pronating the forearm and/or by wrist flexion and/or radial deviation. "Hit into/engage the sponge" via forward weight transfer and/or torso rotation is a different instruction from doing so with the arm. When talking about changes in blade angle during the swing, we must first agree on the starting and end points of the swing being discussed. Players have their own idiosyncrasies and establish the forward approach blade and swing angles at different phases of their swing. Some set it early on, some set it after the forward swing has begun. I think the important questions are 1) During the 3" before, through, and 3"after contact, as viewed from the side, do and by how much the swing angle (as taken from the path of the blade center) and the blade angle change, respectively? 2) Are the swing and blade angles different during this window and if so by how much, and does the difference change or remain the same? 3) Are these angle changes consequential with regard to the short duraction of contact? 4) Are these angle changes execuated proactively by conscious arm/wrist movements?

Commercial unboosted DHS H3 is very playable up to at least the USATT 2000 level. If you feel different, the culprit is either your skills or your blade.

Name of video for searching on Youtube for whom the video does not load: Coaching Tips: Table Tennis Forehand Loop (Episode 3)The swing starts from the shoulder and initially looks like he's going to drive or counterhit the ball---the blade angle is noticeably larger than the swing angle and the swing angle is much less than 45 degrees. Mid swing or so, internal rotation of the shoulder and the partial closing of the forearm take over, drastically increasing the steepness of the swing angle, creating the convex shape, and also seemingly merging the swing angle with the blade angle. To me, at least with this swing, it seems like the swing angle increases through the forward swing to approach or match the blade angle, as opposed to the concept of starting with a blade angle larger than the swing angle and gradually reducing the blade angle through the forward swing to approach or match the swing angle. The degree of forearm movement greatly influences the changes in and relationship between swing and blade angles and the swing shape.

Can't see the video as the uploader hasn't made it available in all countries... Anyway, there is a closing of the blade angle throughout contact which is evident in all pro swings. There are a few mechanisms, including forearm pronation, shoulder internal rotation, as well as increasing the forward lean (the more you lean forward the more closed the blade angle will be when keeping everything the same).

Hey! That's an interesting question about forehand looping with a badminton racket.

From my experience, it really depends on the player's preference and playing style. Some players prefer to keep the badminton racket parallel to the path of the shuttlecock's travel, while others may have a more open racket angle. Personally, I tend to go for a slightly open angle to give my shots a bit more power and spin. How about you? Have you found a specific racket angle that works best for your forehand loop?

I may be all wrong, but I am going to throw this out there. I think that a stroke that "wraps the ball" optimizes your chances for the ball landing on the other side of the table. if your timing isn't perfect and you hit the ball late, with the curved stroke you hit a little lower or more on the back of the ball, more "drive" in a loop/drive. Conversely if you hit the ball a little early, more on top of the ball - more loop in the loop/drive.
