OK, I think I understand you. I do appreciate the links to those discussion, but if you could be a little less cryptic at times I'd appreciate it.
I believe you have valuable insight to add to the discussion, but just referring people to other discussions without giving an overview of why that discussion is helpful is often annoying.
http://asmiforum.proboards.com/thread/2104/shoulder-orientation-overhead-baseball-tennis brings the simple argument that one has to understand skills in TWO sports
and prove that those skills are very close to each other in TWO sports.
You are simply NOT addressing this issue
There is a bad of a story.I ran some experiments related to what you are trying to do.The article you cited showed both similarities and differences between throwing a tennis ball and serving. The operative question is not whether the two are exactly the same - I believe most of us here agree that they're not - but whether throwing a football is useful as a training practice to help develop serve power.
If a controlled study showed they were, then I'd accept that it is a very worthwhile practice. At the moment we have anecdotal evidence that it works, which you can easily be skeptical of. I'm not as quick to dismiss Serena as a potential example because whatever criticisms you might have, she seems to be the best woman server in the world at the moment.

The basic problem is to design a sensible drill before I would fired at the club I work forPerhaps you could tell us about your experiment and also the training you do with modified medicine balls.
My experience throwing the football was interesting but not conclusive. I did hard football throwing and then hit particularly hard serves two days later. I don't regularly throw a football and don't particularly have a strong throwing arm. I do believe I got increased speed gains from training with the speed chain, too. But again, I didn't keep careful data and had an injury that set me back for some time.
I have been using football throwing as part of a serve warmup with a few students, but I haven't done any careful study of it. At least the students seem to enjoy it as a warmup. We don't spend a lot of time at it. Most of my students still have technique errors that need to be corrected and most of the work is focused on ingraining a proper motion pattern.
You are a very smart coach.Julian's posts give me a headache. It's like a roundabout with no exits.
I recall Ballin Bob posting videos of throwing a football. He was having to learn technique but it would be interesting to hear if he noticed a gain in serve pace from that practice?

It gets interesting- are you saying that all three: a topspin serve, a slice serve and a flat serve do have a spiral component?Football throwing is considered the gold standard for throwing training of any sort - because the need to get a spiral reinforces proper mechanics.. My coaches use footballs too - its very common. Its not new information at all - likely something her Dad or her coach did with her at an early age.. Essential tennis guy has some videos on this.

Systemic Anomaly discussed three different kind f spins: one of them being a spiral spin.Apparently one of the things mentioned in Serena's master class is that she spent a lot of time as a child throwing a football (American pigskin) and credits much of her serve success to her ability to throw a hard good spiral.
This isn't the only place I've heard this. 5263 mentioned that his son (who won several fast serve contests as a junior) believed that throwing a football helped him develop a lot of pace on his serve. And more than that, the Legendary LeeD has boasted about his ability to throw a football for distance as a small teenager, and he was known for his lefty bomb serve in his youth.
I've started using football throwing as a training aid with my students. I tend to think the NFL sized balls are too big for most people's hands, but the junior balls can be reasonably held by most. I also find that throwing for distance is the most useful practice as it creates more of an upward arm path like a serve. Also, the properly thrown spiral uses a an internal rotation motion at the release in order to create spin to stabilize the ball, something that you don't necessarily need to do when throwing a baseball.
Does anyone else use football throwing as part of your serve training?
It is interesting that you misrepresented Ballin Bob. Please read his post.Ballin Bob tried it for a couple months. Never showed his progress, because he threw onto an open field.
Most people don't throw high enough, but somewhere between 35 to 45 degrees seems obtimal for longest distances.
And like a javelin thrower, if you want to throw for distance, you need a running 7 step full speed run before you release the ball. The runup adds at least another 1/3 to your throw distance, compared to taking just one step.
I"m down to around 47 yards, first throw, no warmup. Since I can't push off with my bad left ankle, broken my left collarbone twice, and separated my left shoulder 3 times, I've aged very ungracefully. Also, I can't run or jog at all, taking a huge distance off my football throws.

Let me make it as simple as possible-I do not see any reason to teach a spiral spin for tennis.
So I do have a problem with using a football throw for teaching purposes.
We can try to bring Systemic Anomaly into this conversation.
Sorry I'm late to the party. The football training went on for 6 months. I never was able to lower my elbow on serve, but I did see an increase in serve pace. It also gave my serve a much needed rhythm. I found it easy to translate my throwing rhythm into my serve and it made the serve a lot more simple.
Still use the football to warm-up before a match. I do recommend it.

Basically your last sentence explains some difficulties of using non-tennis balls for teaching serve.I think SA's discussion of spiral spin had to do with hitting the American twist serve. The spiral spin, as I understand it, explains why the ball appears to be a topspin slice but then kicks the opposite direction on contact.
The spiral on a football is the result of the internal rotation and pronation imparting a spin to the ball on release. As you noted on the study you cited, the timing pattern perhaps is different, but the motion does seem analogous to the internal rotation on a properly hit tennis serve.
The related post by GuyClinch above is a bit confusing on the subject of mechanics and spiral.I think SA's discussion of spiral spin had to do with hitting the American twist serve.

Nice discussion on using the football throw to train for serving (other than the roundabouts of course).Good to hear that you think it helped you. 5263 said his son felt throwing for distance like you were practicing really helped him with his timing and creating easy power on the serve. Of course, he was also spending a lot of time on perfecting his serve form.
One advantage of throwing a football is that it is a fun activity that can be done off court. In my area, I can just bring a ball and mess around when on the beach and perhaps still give my serve more pace.
Interestingly enough your last sentence is very vital for what wildvolley is talking aboutNice discussion on using the football throw to train for serving (other than the roundabouts of course).
Yes, Imo the high football throw is an extremely valuable training aid. My youngest son has been playing up a division into the 18s and is already quite a dominant server in most of his matches. I don't think he is quite where his big bro was, but actually may be getting more 1st serve aces per match. I just share this to show it was not just that the 1st son was a fluke or something and that the next son is right on track as well. Imo it can be taught and trained.
Imo that ISR/pronation that can be focused on by throwing a football, is the big motor for your serve. I would say that the football toss is best for developing timing of the chain and warm up, both of which will impact your ability to serve well consistently. I'd say that regular throwing with the right form would help your avg 1st serve and even 2ond serve speeds. I'm not as sure that it would affect your max recorded speed that much for a variety of reasons, but that is not as important Imo.
Burn Notice, are you asleep?
All I talk about is a running start compared to a standing start! Over and over, I stress that. I"ve mentioned a dozen times a javelin throw, 12 running steps, compared to a QB throw, ONE lead foot step.
When you come in late to a thread, don't diss the posters because YOU didn't read the posted threads.
Remember, I also keep posting about running steps for long jumps, javelin throws, baseball throws (outfielder compared to short stops), spear chuckers, and everyone who throws anything.
Actually I don't agree. I expect most players would be very happy to be able to consistently repeat their very best ever serve.Interestingly

Which would make a better training tool for tennis serve, a regular football or a weighted one (2 lb)?
Good question. I'm not sure we really know. It might depend on your fitness and training level already.
Ljubicic was throwing a weighted football in the photos I've seen online. I'd guess most people posting here have only worked with normal footballs.
Just pointing out my mistake above and the edit I made.Actually I don't agree. I expect most players would be very happy to be able to consistently repeat their very best ever serve.

Oops, I misread his comment and actually do agree, Sorry Julian.

I don't know that I can say that the ISR/pronation of throwing a football is responsible for the spiral, but when throwing a football properly, it uses ISR/pronation much like it should be done with the serve.Spiral spin is useful for twist serves, for some underspin specialty shots and, perhaps, for the banana shot in tennis.
I do not believe that GC was suggesting that imparting a spiral spin on a football somehow translates to developing a spiral spin for tennis strokes. I believe that he was suggesting the imparting spiral spin on a football will cause the hand/forearm to pronate when the ball is released. Is that true GC?

People can throw a baseball 115 meters?Baseball throw for distance is also good.
Most high schools have a 300' mark from home plate, at least as of 20 years ago when my g'f had a son at Tomales High School.
Roberto Clemente was rumored to have thrown 380 feet in the air, from a 410 warning track to the plate on one short hop.
I'm trying to understand why doing a motion from another sport would improve a motion from the sport you're trying to work on instead of doing more of the motion that you're trying to do.
This post has some information on the similarity between the throw and the serve. Both use rapid internal shoulder rotation for speed. ISR occurs at the shoulder joint and involves the upper arm bone rotating around its long axis (a line down the center of the upper arm). That upper arm rotation does not show directly in these pictures but the forearm is at an angle and it indicates the ISR rotation of the upper arm.The best practice for a tennis serve is throwing a baseball. Among my friends the best server has a background in baseball. He's left handed. He played baseball as kid, but the other kid he played with only has right handed gloves, which are left handed. So he learned to throw a baseball right handed. Fast forward to now, when he plays tennis, he serves with his right hand, but switch to his left hand to play.
The tennis racket is only the extension of the hand. He can put all kinds of spins and slices on the the ball.
You haven't watched the Karate Kid, the original, or Rocky IV. Chopping a tree down is exactly like chopping an opponent down.
Here are the pictures from a Pat Dougherty Youtube video.
For drilling the most difficult concept - rotating the upper arm with ISR, it looks as if a proper throw is very similar to the serve as you have often said. Here her upper arm and body orientation are even in the same position as for her serve.
A high speed video showing the throw and the serve instead of these blurred captures from a 30 fps interaced video (double images) would be great.
The ASMI link in reply #34 also has a very detailed response from a researcher very familiar with this issue. He points out similarities and differences.
