Fastest punch
Appledog
Anyone faster? Any and ancedotes welcome.
I wonder what the fastest speed the hand or foot can travel at under
the body's own power. Ancedodes are welcome.
This is for a noble cause.

logically nolan ryan could punch 100 miles an hour.
a baseball cannot accelrate after it leaves a ptchers hand, so when
its thrown 100 the hand must be going at least 100.
if you took the ball from his hand and had him make a fist it would
have to be going around that fast...ok i could get into more miner
details that may vary the speed a tiny fraction, and one could debate
if he throws it like that is it a punch or a slap? punch if his fist
is closed i say.

I dunno, I've heard hitters say that thrown with
heat, like Randy Johnson, the ball might still be
accelerating as it crosses the plate.

The way a pitcher throws, the hand trails slightly...
for a punch, the hand must lead. So it's not
comparable.

The only part of a pitcher's hand that travels as fast as the ball
at release is his fingertips, and that's only because he puts every
muscle in his body between his toes and his fingertips into it:
There's just no way in hell he can rearrange the effort to make his
whole hand move that fast.
I remember somewhere seeing an analysis of Muhammad Ali throwing his
so-called "anchor punch" on film- came out to around 35 mph.
Since nobody could see it coming in time to block it, I think that's
plenty fast.

I know how a whip works. A finger is not
a continuous flexible medium.
A better analogy would be nunchuk.
The mechanics of nunchuks might explain
the hand speed of a baseball pitcher. Which
obviously wouldn't apply to a straight punch.
But looking at the wrist posture, I don't
think you could convert a pitch into a punch.
Possibly a karotty chop, though... Nolan
Ryan might be able to perform a 100 mph
karotty chop...

tons of control to hit right (though I thoroughly admit ignorance in

it would likely hit like hand-spaghetti.. Painful but not controlled.

That is physically impossible, obviously.
The rising fastball and accelerating fastball are optical illusions.
You should watch my son strike kids out with a simple circle change
and fastball combo. I throw the same sets of pitches to them and the
things work like magic.
A good circle change fools the shit out of you...it comes off the hand
looking like a fastball. I catch for my son when we practice and I
swear the ball dies halfway to me whereas the 4 seam seems to rise.

The baseball throw is similar to the big overhand iron palm - in fact, I
wrote a piece here years ago emphasizing that very point. The key
feature is that the hand is "thrown" with a whipping motion and achieves
much higher velocity than a punch.
As for control, baseball pitchers obviously exercise enough fine hand
control to determine within inches where the ball passes 60+ feet away
at home plate - less control would be necessary to direct where a palm
hits on a human target at only arm's length.
There are differnces, of course, such as that for overhand iron palm
neither leg is lifted off the ground.

control, of course, but the pitcher doesn't have to worry about a hard
contact on the hand at the end of the throw. an iron palm strike ends in
a massive contact, which the hand would have to be prepared for, no?

Yes, iron palm training generally involves hand conditioning so that it
can withstand the wear and tear of delivering such a powerful strike.
However, the *overall body mechanics* of performing an (overhand) big
iron palm are remarkably similar to a baseball throw, especially the
whipping action where the elbow precedes the wrist which only catches up
and passes it later.
However, the standard initial training for iron palm projects the hand
downwards, not forwards (usually onto a bag filled with beans, sand,
etc. on a low very sturdy support). To mimic this downwards whip
(without any hand/palm contact and the accompanying wear and tear) do
the following as either a gedanken or real experiment:
Stand with feet somewhat wider than shoulder width, right hand holding a
large round stone (tennis ball size or so - not a light pebble)
somewhere near waist level. In one smooth continuously-accelerating
whip-like motion raise your hand above your head and then "throw" the
rock downwards as if trying to bury it as deeply as possible in thick
mud at your feet. At the point of release your hand should be a foot
or less above the ground and you will be squatting in a "horse"
position.
Or, as a different approach, consider performing this side-arm version
of the iron palm (it's the version that, in my experience, most people
find best to "get the feel of" iron palm):
Swing your right arm/hand in a sideways horizontal whipping motion *as
if you were trying to throw a pebble really fast to "skip" as many times
as possible on a pond.* If you wish, you can then try this same
whipping side-arm on, say, a heavy bag, but giving a "power slap" with
your palm (you will start offset a bit sideways from the bag). Yes, it
stings, but, with practice, you will find it lands with a hell of a
wallop (far, far heavier than an ordinary slap - it's a power blow, not
just a stinger). But, yes, if you do it right your hand will really
burn (it may take you back to 7th grade and getting the strap :-) You
can tense you palm/arm *a tiny bit* on impact but any more than a tiny
bit will slow you down a lot and reduce power greatly. If in doubt
throw it completely relaxed, especally at first, as a "dead hand" on
impact. Whiplike speed first, impact control second, should be your
goal.

Randy Johnson is 6' 10" tall and the ball is always travelling
downward with the height of the mound included. Since gravity is still
in effect when the ball crosses the plate, it can be accelerating due
to gravitational force and the rising effect of the fastball is just
the "levelling off" of the ball as it becomes parallel to the plane of
the field. N'est pas?

Uhh, you seem a little "physics challenged."
You see, gravity acts *downwards* and does *exactly dick* towards
increasing or decreasing the *horizontal* speed of the ball. In short,
gravity has got dick to do with the matter.
Regards,
PS It doesn't matter whether the pitcher is 8 feet tall or 3 feet tall -
the ball must pass over the plate in the strike zone between knees and
armpits (roughly 2 to 4-1/2 feet above the plate). To achieve this a
slow pitch must have some initial *upwards* velocity in addition to the
forward velocity while a very fast pitch (95 mph or so) can leave the
pitcher's hand nearly horizontally (and will drop 3 feet by the time it
reaches the plate).

What about the levelling off of the pitch as it goes

"Levelling off" Say what?
A 95 mph fastball leaving a pitcher's hand horizontally will fall
roughly 3 ft before it crosses home plate (near the lower limit of the
strike zone). Ignoring air drag, the forward (horizontal) velocity will
be the *same* as when it left the pitcher's hand (including drag it will
be less). The ball will be falling (not level!) as it crosses the
plate. Gravity has dick all effect on forward velocity.
In fact, the flight path of ANY ball crossing home plate in the strike
zone (say 2' to 4.5' above the plate - knees to armpits) MUST be
inclined somewhat downwards. No human can throw a ball so fast and from
so low a release height (i.e, besides being superhumanly fast he would
need to be in a pit, not on a mound) that it would *climb* after release
and then just level off as it crosses the plate in the strike zone 60.5
feet away!
More simply, if the ball leaves the pitcher's hand at a height somewhere
around shoulder height (say 5 feet) how the fuck would you expect it to
be travelling "level" as it goes through the strike zone (height only 2'
to 4.5') at the plate 60.5 feet away?
More simply yet, since:
a) the upper limit of the strike zone is about 4.5'
b) the ball is released at an equal or greater height (say 5')
c) the ball MUST be on the downwards leg of its parabolic trazectory as
it crosses the plate (if it were on a rising first half of the parabolic
trajectory, the ball would NECESSARILY be at a height greater than that
at which it was released and therefore ABOVE the strike zone)
ERGO: The ball CANNOT be in level (or rising) flight as it crosses home
plate - it MUST be falling.
Sheesh!

No such thing...the magnus effect on a 4-seam pitch merely reduces the
drop due to the lift imparted by the spin.
The rising fastball or accelerating fastball are optical illusions
based mostly upon parallax effects.
If you watch the pitches from the dugout, you see completely
differently.
Seriously, my eldest son pitches and throws fastballs and changeups.
They look completely differently in terms of the apparent speed and
motion of the ball as viewed from the side versus from the plate.
Your brain plays tricks on you. For example, a well-thrown circle
change is indistinguishable from a fastball in terms of the body
mechanics and armspeed of the pitcher. Consequently, a batter's brain
fools him into believing that the pitch is in fact a fastball, and he
times his hitting motion to account for that, unless he is reading the
grip or is looking for that particular pitch.
When I catch for him, occasionally he will throw a changeup when I
signal fastball. In this case, I get fooled too. The ball appears to
be a fastball for the first 1/3 of the ball's flight, and then it
appears to hang in the air, die and dive. When viewed from the side,
the changeup is obvious from the outset based upon the ball's flight
path. Sometimes, I signal changeup and he throws that pitch and my
initial reaction from the ball off his hand is why did he throw me a
fastball when I just signaled circle change.
Likewise, the relative motion of the 2-seam versus 4-seam fastball,
the latter appears to rise. You find yourself lifting your glove into
the terminal point of the pitch instead of merely being stationary.
This is how the high fastball strikes out batters; they misjudge the
amount of drop and chase pitches that are above the strike zone. But
there's no magic in it.

I dunno... I recall a seeing a wildlife documentary

he was going so fast, he went like 100 feet

In martial arts, there is what is known as the 1 inch punch. This is a
punch which starts from an inch away but, yet, is powerful to break a
board in half. Bruce Lee was able to do it.
At my fastest reaction speed, when someone threw a projectile at me
from behind (it was in an office and was part of the horseplaying the
cubicle dwellers routinely do), I first became aware of it when it hit
my back.
In the time between when the collision started to take place and
before it was finished colliding, I had already turned around and
snatched it out of the air.
Then came the ominous moment. Office mates gasping at the surprising
speed (and the ominous background music playing in the background as
it always does), I slowly placed my hand out toward the aisles and
opened it up -- showing for all to see that the projectile was in my
hand.
The reaction was so fast that nobody even knew it happened until it
was all past. The arm and hands moved so fast in the air that it made
the same kind of cracking sound a whip makes -- just like the sound
effects in martial arts movies.
When the office mates asked what it was, I told them what I thought
(at the time it was) -- the arm moved so fast that the sound barrier
was actually broken and they were hearing a sonic boom.
The truth of the matter is that the arm was moving so fast that the
ligaments popped and made the characteristic sound they do. I don't
know how fast the reaction was, but you only need to estimate -- by
watching a high-speed video, say -- the time an impact takes place
during a collision (particularly the amount of time something makes
contact with the body while it's bouncing off) and match this against
the amount of time it takes to turn around, to swing the arm around
and catch the object. It's well over 100 MPH.
But, one thing I can say for certain. I was aware of the passage of
time at the speed the reaction was taking place at. Subjectively it's
as if the world comes to a slow-down or dead stop. The inertia of
everything goes up BIG TIME. In effect, the effective inertia goes as
the inverse square of the time scale. So, even a moderate speed-up and
you're suddenly weighed down.
It is awfully damned difficult to move anything in the "slow-motion"
world, even the slighest effort requires significant exertion at that
speed. Hence the sound you hear "arumph!" often when reacting fast.

With no propelllant or other force on the ball it CANNOT be still
accleerating. As soon as it leaveas the piotcher's hand it begins to slow.
Air resistance and gravity act on the ball. as soon as it is released.
Simple physaics. Take care

Bruce Lee was able to do it? What about us mere mortals?

There can be only ONE!

You learned this after you faster-than-sound arm trick?

That's the sound your mom makes.

At one point in my life, near forty years ago, I was totally
convinced that such accounts had to be unphysical BS, and that all
films of same had to be SPFX.
Then, one day I stepped out of my bedroom in a house I shared with
some roomies. They didn't know I was in there, and had hung a
dartboard on the outside of the door. As I stepped out, the first dart
was thrown from not quite twenty feet away (the door was at the end of
the hallway). Fortunately I was eyes-front when I stepped out and saw
the dart at maybe arm's length away. I reached up and snatched it out
of the air barely a foot from my face. From spotting the dart coming
to grabbing it, I saw the world go into slow-mo, though I didn't feel
any unusual resistance; instead it seemed that I was paying *real
close* attention and moving *extra carefully* so as not to miss.
When my mind caught up with what had happened my heart went into
overdrive (too late, of course); then I saw the expressions on my
roomies' faces, which made me relax and laugh aloud instead of
throwing the dart back.
They claimed my arm made the same whipcrack sound, though I didn't
hear it.
