[RCSE] Handlaunch Shoulder Syndrome???

2000-09-14 Thread Sean Porter


Wow!!
That sucks...I would really be pissed if my shoulder
did that. I guess the first day of the HL season I
will experience some tightness. Stretching usually
helps to eliminate it though. I hear alot of HL people
complain about the shoulder pain. I have never really
had it. Of course, I grew up on a tennis court, so
overhead serves and smashes were the norm. I probably
developed the tendon strength at a young age.

BTW... I think we should throw with our hips and legs,
not the shoulder anyway. When you watch the javelin
dudes, they rotate their hips and then the upper torso follows.

ll be able to improve faster than if you tried hard at the
 beginning.  I have coached a lot of athletes.  The first part of every
 season starts out with drill work.  The goal is to get the movement perfect
 not break down the body.  Nothing is hard, no one is tired at the end.  You
 just have to give the body 2 to 3 weeks to adjust.  I know I have gone on a
 bit on this point, but I have seen a lot of injuries in my time and if I can
 help anyone here break into HLG and not hurt themselves doing it, all the
 better!

 Good Hunting,

 Subject: Re: [RCSE] Handlaunch Shoulder Syndrome

 I must be making some progress with HLG-- my shoulder and elbow are getting
 sore.  I've been throwing an hour or two on Saturdays/Sundays and trying for
 a few minutes to a half hour on weekdays over the past three weeks.

 Flying the DJ Aero Chrysalis.

 I have been concentrating on getting a "good" setup, throw and followthrough
 (or at least what I perceive as "good", being self-taught for now).  I've
 not programmed an elevator launch preset on purpose so I can pay attention
 to getting a solid horizontal throw.  I have been putting a bit of "english"
 on the throw so it does throw "up" a  bit so I can fly the plane.
 Generally, I get about 15' altitude and about 40' out where the plane
 transitions from being thrown to gliding.  From there I'll bring the plane
 around 180 deg and catch it or land near my feet.  And then throw again.

 One "problem" is that I usually end up HLGing in a moderate 5-7 mph wind and
 it's a "bear" to bring the plane around back to me in the wind at low
 altitude-- the airspeed and penetration just ain't there.

 But this initial practice has been good to give me a feel for throwing.  And
 as time wears on I'll work on new throwing routines and, hopefully, get
 better at it.  In a little while, once I get my throwing style established,
 I plan to visit my chiropractor, who does sports medicine, and get an
 evaluation of the mechanics of my throwing technique.  Or sooner, if the arm
 gets real sore.  :)

 What sort of a throwing practice routine would you  (all) recommend?  The
 throw-circle-catch-throw routine is OK, but may become uninteresting
 eventually. ;)

 BTW, I've been directed to a WebSite on throwing "The Wonderful World of
 Throwing", which is javelin-oriented, but applicable to what we do:

 Take care,

 "I throw up."

 to the proverbial "Can't find his ass with both hands" situation.  One of
 the hands wasn't working.  Is that an excuse?

 I suspect that I am not alone in this problem, and I have been
 researching treatments.  So here is a three step program to cure Handlaunch
 Shoulder Syndrome that seems to be working for me.

 A.   Make a minor modification to your HLG, to help prevent further injury.
 Carefully locate the CG on the fuselage, and make a small mark at that
 point.  Drill a hole in the bottom of the fuse 1/4" ahead of that point and
 install a little towhook.

 2.  Naproxen, two tabs twice a day.

 III. A series of four very low impact and simple exercises.

-- bend over so your torso is more or less horizontal, let your arm
 hang down and gently swing your extended arm around in a circle, going first
 clockwise 12 turns and then counterclockwise 12 turns.  Don't do anything
 that hurts.  Each day, add a few circles.

 --  stand up and pretend you are using the arm on one end of a crosscut
 saw--12 or so push-pulls on the saw.   Each day add a few saw cuts.

 --hold your arms to your sides and gently flap like a bird.  If you are
 a severely wounded bird, like I was, just flap a foot or so up from your
 side, and do 12 or so flaps.  Each day flap the arms a little higher and a
 little longer.

 --shrug your shoulders, and from time to time pretend you are trying to
 hold a soccer ball between hour shoulder blades.

2000-09-14 Thread David A. Enete

Wow!!
That sucks...I would really be pissed if my shoulder
did that.

Even worse if your groin did that.  :)

BTW... I think we should throw with our hips and legs,
not the shoulder anyway. When you watch the javelin
dudes, they rotate their hips and then the upper torso follows.

I wonder about this.  Remember that in javelin throwing, the idea is 
to reach max speed and then impart max force on the javelin...without 
going over the arc marking the end of the runway.  We however don't 
have to try and stop our bodies after the throw (no balk line in 
handlaunch).  So, should the body "snap" like a whip, or flow like a 
catapult?  Wurts mentions "bending over" after his throws (3-Rs 
video).  But it is a natural extension of the follow-through.

I don't throw with as much force (or pre-throw speed) as most.  I 
think of my body as a wheel (legs spread, arms straight and 
extended).  Max speed happens when I accelerate one arm and let the 
other side of the wheel compress (think of a single bladed prop with 
a counter-weight that is close to the axis).  Longer time with the 
hands on the plane that way and energy is conserved...imparted to the 
plane.

On another related item.  I have seen what is probably the coolest 
way to do a soccer throw-in.  A woman at Stanford (?) on their soccer 
team meets the rules requirement of having both feet planted and both 
hands on the ball by holding the ball above her head, running 
forward, placing the ball on the ground (still in both hands), and 
doing a full somersault over the ball, onto her feet, before 
releasing it as her body whips.  Great speed!

Tom,
You can solve it with a simple one step solution. Get, or build, a modern
discus launch hlg.

Don't think so. I threw a Red Herring for a while and it is just a whole
other set of muscles and strains from that action. Jut takes working up
to it. Working out with a HLG can be Heaven or Hell. The better you get
a working lift the less you'll hurt. When the air is flat put it down
and wait. You know when there is lift!!!
