100 mph...

Does anyone else think it's kinda funny how the variation of speeds of pitchers seems to be a 100mph maximum (with a few obvious exceptions)?

Was that just a coincidence, or were the baseball diamond dimensions specifically built so the fastest anyone could throw was around 100? It just seems kinda weird that people would stop getting faster right around a nice round number.

 

Which also gets me thinking about why a normal pitch count, or even a set pitch count is usually 100. Again, was that planned at all?

I guess the real question is, though,

if the home team notices that the opposing pitcher is nearing the 100mph mark in the 1st inning, can it either move the mound back to 84 feet 3 inches, or redefine home plate to be the spot where the ballgirl sits in left field?

OH YEAH WELL SHOW ME IN THE RULEBOOK WHERE THEY AREN’T ALLOWED TO!

What's that you say?

Pitchers just happen to be throwing that hard at the moment. I remember in the late 80s when a guy who came out of the bullpen and threw 90-93 was a real fireballer. Aside from Nolan Ryan, there weren’t many guys that we would still consider power pitchers. You were lucky if one guy on your club could break 96.

Nowadays, every team has a couple relievers throwing 97-100 and starters are routinely living above 95. There are two possible explanations, either speed guns were all calibrated wrong, in which case Nolan Ryan was probably throwing 115, or guys just didn’t throw as hard. I’m going with the latter.

15 years from now, the power closers will probably be throwing 105+ and people will wonder why 97 used to seem so fast.

Yeah but

I’ve also read that ~104 is the theoretical “maximum” given the stress-handling abilities of the human shoulder.

If that’s true the whole “THE MAXIMUM IS SORT OF A ROUND NUMBER” thing is somewhat valid to talk about

by Simon Phoenix on Jan 18, 2009 9:40 PM PST up reply actions   0 recs

Even if the maximum is sort of a round number

that doesn’t imply that the dimensions of a baseball diamond were built to accommodate it.

Not really.

Even if there was any compelling reason to believe that 104 mph was the maximum a human could throw, that isn’t a very round number. There’s also no compelling reason to believe that 104 mph is the speed limit. Not unless you think that Joel Zumaya is the pinnacle of human evolution.

The commonly held belief (backed by an understanding of basic physics) is that your height and arm length increase velocity. By having long arms, you are launching the ball from a bigger lever, so the force you apply is essentially multiplied by the distance from your shoulder.

If you have a really long arm, you can throw harder than if you had a really short arm, without placing any additional stress on your shoulder. That alone makes it completely impossible to have a limit on how fast a person can throw. Besides, when you see a 5’10" guy throwing as hard as any other starter in baseball, you gotta wonder how hard he’d be throwing if he were 8 inches taller.

And even if all of that wasn’t the case, if there was a demonstrable speed limit that actually was a round number and no one could throw any harder than that, it still wouldn’t mean anything. When the dimensions of a baseball field were developed, there wasn’t even any way to measure ball speed, let alone perform the medical tests and incredibly complex physics equations required to determine what the maximum velocity would be.

It would just be a coincidence. But since there isn’t any evidence of a speed limit, or any reason to believe that it would be a round number, there isn’t even a coincidence. Just a common human tendency to see patterns in random data.

by Vatinius on Jan 18, 2009 10:00 PM PST up reply actions   0 recs

I over-simplified, but it's mass that adds stress, not length

Angular momentum and total work in the system are unchanged by alterations in length, only mass. An increase in length directly increases the torque, adding release energy without putting additional stress on the arm. The argument is predicated on the assumption that people can have sufficiently different body types that one has arms thinner and longer, but with equal mass.

At that point, the argument becomes whether a thinner longer arm is able to be as strong / withstand as much torsion as a thicker arm. I’m not a kinesthesiologist so I really don’t know how that shakes out, but I would be surprised if the loss of a little bit of girth would seriously weaken the structure of an arm.

If two people have arms of the same mass but different lengths, the additional stress through the shoulder is extremely negligible*. Stress on the arm is greater due to the increase in centripetal force, but not so much that it would put the arm under more stress than the shoulder.

*Moment of inertia increases with length, but that just makes it more difficult to accelerate your arm, it doesn’t have any effect on the forces at play once you have accelerated it. This creates the argument that perhaps there is a point at which the increased energy needed to accelerate the arm becomes so great that it outweighs the increase in potential angular momentum. i.e. there isn’t sufficient time (given the relatively short length of a pitchers delivery) to fully accelerate your arm.

I’m not claiming that I have some crazy computer model to prove that there isn’t a maximum speed, I’m saying that there’s no reason to believe that there is a demonstrable maximum speed (specifically, one that would be imposed by a structural weakness in the shoulder).

by Vatinius on Jan 18, 2009 10:59 PM PST up reply actions   0 recs

Also, I'm not sure what role centripetal force plays on the shoulder

My whole point is based on the assumption that torsional stresses are the primary force at play damaging a pitcher’s shoulder. Such that the stress is caused by the transfer of force, by the muscles, through the shoulder to accelerate and control the arm.

I’m not an expert on pitching mechanics, so it’s certainly possible that the primary stress is in fact centripetal, in which case the force on the shoulder would increase due to both the increased length and the increased angular velocity. If that is the case, then yes I am wrong about not adding any stress, but it still wouldn’t add so much that going from 104-105 would be impossible.

I guess my confusion stems from the statement that this is a limit on attainable speed. If it becomes a debate about whether the centripetal force will become too damaging, then that wouldn’t affect the ability of a person to throw that fast, it would just wreck their arms. Two people with arms of equal mass, but different mass, could apply the same amount of force and throw at different velocities.

Maybe the long arm, harder throwing guy’s shoulder would give out first, but that isn’t really a speed limit. Though given that most pitchers wreck their arms anyways, I still don’t think it’s particularly compelling evidence.

by Vatinius on Jan 18, 2009 11:10 PM PST up reply actions   0 recs

What?

Double the lever arm and you double the force couple, increasing stress in whichever ligaments are carrying the forces. In addition, the deceleration at the end of the pitching motion becomes much, much harder.

But what would I know. It’s not like I have a masters in structural biomechanics*.

*Oh wait I do.

by Graham on Jan 18, 2009 11:23 PM PST up reply actions   0 recs

So which is the primary force causing damage?

This is the part that I’m not clear on. It sounds like you’re saying that the primary limiting factor in pitch velocity is the capacity of the tissues in the shoulder to withstand centripetal force. My background is in physics not biomechanics, so I’ll take your word for it, I’d just like a little better explanation.

I assumed that the tension in the muscles from accelerating the arm would act against centripetal force. Does this not happen, or are the muscles involved simply too weak to counter the outward force? And how significant is the torsional stress from total work applied compared to the centripetal force?

Also, are you arguing in favor of the speed limit or just pointing out that I don’t know the inner workings of the shoulder? Because even if the stresses on various bits of shoulder structure increase by a significant amount, the increased length still acts as a force multiplier, and increases the velocity of your hand.

I can’t see how the increase in rotational stress could be dramatic enough impose a maximum velocity.

by Vatinius on Jan 19, 2009 12:13 AM PST up reply actions   0 recs

Essentially, looking at biomechanical systems as pure force problems doesn't make sense

It’s not the physics that’s wrong, it’s the framework.

There is a speed limit somewhere in the windup/release of the baseball based on the ability of the human body to store and release potential energy without any failure of the soft tissue (or I guess you could bend/shear the bones too), but treating the arm like a lever out of the shoulder doesn’t make a whole bunch of sense – it’s way too simplistic.

In essence, the more impulse the hand transmits on the ball, the more stressed the arm will be, no matter how long or short that it is. The real advantage height has is in gravitational potential energy and a release point closer to the batter.

Stupid question

Do most the pitching muscles get torn under acceleration or deceleration of the pitching motion?

by Edgar for Pres on Jan 19, 2009 6:12 PM PST up reply actions   0 recs

I don't know, but I'd guess deceleration is where most rupture occurs.

It’s not really the muscles you ought to worry about though, it’s the ligaments and tendons.

Said employer needs to be able to depend on you to be at your productive maximum. They have every right to check to see if you’re intoxicated on the job because you are then violating that trust. On the flipside you get things like workers comp and workman’s laws that ensure you are working in a fair workplace. They have every right to make sure that their employee is treating them fairly by not being intoxicated.

Verlander and a couple others have hit 101-102 on the gun, don’t they?

by Gomez on Jan 18, 2009 10:14 PM PST reply actions   0 recs

Gun times are (largely) bogus

There’s a roughly 10mph difference between the out-of-hand speed and the across-the-plate speed, thanks to air resistance slowing the ball during flight. So depending on where you make your measurement, you can get a wide variety of results for the same exact pitch. This is also why I don’t like the term “fast gun” and “slow gun” because the instrument taking the reading is likely calibrated properly 99% or more of the time, it’s just that there seems to be no consistent standard for where they should measure the pitch speed.

Fangraphs had Verlander at 95.5mph on his average FB three years ago (just 93.6mph this year, though), so I’m sure that his out-of-hand velocity was over 100mph on more than one FB back in 2005. If you take the average speed of the ball from his hand to the catcher’s mitt, my guess is that he’s never as high as 100mph.

Fangraphs has Zumaya at 98.6mph in 2006, so it seems plausible that he could have dialed it up for a few pitches at 100mph. There are probably a handful of other pitchers that do this from time-to-time.

by ubelmann on Jan 18, 2009 11:36 PM PST up reply actions   0 recs

Thats because

there is no consistent standard release point from pitcher to pitcher or in some cases from pitch to pitch. The only consistent place to measure from would be the front of home plate and nothing would be less sexy then dropping everyone’s pitching speed down 10 mph

I guess I could have been slightly more explicit and instead said “it seems plausible that [Zumaya] could have dialed it up for a few pitches at or above 100mph.”

Radar gun data doesn’t really help the discussion, though, since it’s so inaccurate and pitch f/x exists. Someone with better database skills than I have can probably go through last season’s data and find a handful of pitches that topped 100mph.

except that if home plate was 10 feet or 100 yards away from the mound it would not affect how hard pitchers throw. And pitch counts are not usually set at 100. Actually, I’m not sure this post has any grounding in reality or logical thought process.
