Read up on the form for these exercises and consult an experienced trainer. Deep squats aren't necessary to build leg power, though many injuries occur here. As the other fellow stated, build up gradually. Many injuries can be sustained during squats due to the premature addition of weight, which will cause leg wobbling due to the lag in the development of your stabilizers. Some may suggest the Smith machine for safety, but this safety is left behind in the weight room. You may notice that after training on such machines, your legs will be wobbly during actual activity such as sprinting as your stabilizer muscular development has not kept pace with that of your prime movers. There is a lot of research in progress in the reduction of injuries that are incubated in the weight room. Injuries are costly to professional sports, so you can understand the motivation. >to full extension). One leg at a time.

It's good for light weights, but anything more than that will strain your knee in a manner that does not mimic similar loading vertically, as in a squat. Be careful with this machine. Also, the high degree of quadricep isolation offered by this machine appeals to body builders, but really, it doesn't develop muscles in coordiation with the rest of your body. Your quads are stronger, but other than the bicep, other leg muscles are largely neglected. --__--__-- Message: 2 Date: Mon, 2 Aug 2004 05:06:26 -0700 (PDT) From: Nate Defensor To: Eskrima Digest Subject: [Eskrima] Greco-Roman Wrestling Reply-To: eskrima@martialartsresource.net Anyone out there know of any Greco-Roman Wrestling clubs/Schools/Groups or associations?

Thirdly, I assume that your Body Mass Index is near 20. Fourthly, how much time have you allowed for the pains to go away? I had to stop all of the above activities for the same reason. After about a year I can now walk down the stairs without pain. BTW, yes, you can expect functional decline not just in your knees, but heart, lungs, brain, you name it. After 25 you are pretty much past your peak. I hope that, if not helpful, you found this message uplifting. ==================================== (1) Yep, a couple of times, and he had me pass through a sports fitness clinic each time (2) I "retired" from the SCA several years ago, and pretty-much gave up jogging...although I still do jog a bit occasionally, but only after having gotten a copy of "ChiRunning" by Danny Dreyer, on my Tai Chi sifu's recommendation. Jogging is now possible again because the mechanics are different. Possible, but not painless. (3) I have no idea what my Body Mass Index is, but I just turned 49, stand 5'11", and am ~25 lbs over-weight (I weigh 205 lbs). I need only look in the mirror to know that I am not aging gracefully. :( (4) Well, the last X-Ray was in the summer of 2003, and the pain ain't gone yet. Some days are better than others, frankly. I still retain much of my mobility, until it comes time to do some kind of squat -- and then my knees start grumbling enthusiastically. Well, any message with good information in it is appreciated. I realize that the system as a whole is destined to succumb to entropy, and there's not much I can do about it, but I don't want to "fade quietly into the night." ==================================== Crafty Dog wrote: A yoga teacher of mine says "Knees are escape valves for hips." The tighter and more imbalanced the hips, the more that too much is asked of the knees. Also look to the foot for imbalances there. ==================================== One of my fellow Tai Chi students is a chiropractor, who recommended that I start buying inserts for my shoes. Tried it for a whole year, in all of my shoes. Again, I didn't see a whole lot of difference. He didn't say how long I needed to wear them, or when I would notice any improvement. Perhaps I am just too impatient, and the point of these efforts is to slow the deterioration, not restore lost functionality.... ==================================== Tom Valesky wrote: Since I started doing powerlifting and added squats into my workout, my knees have never felt better. I wish I'd have started when I was a teen; maybe I wouldn't have had to put up with injury-prone knees. If you go this way, start with light weights and high reps (i.e. 20 reps or so) and increase the weight gradually. Focus on form. ==================================== I was doing deadlifts regularly over the last winter, following the advice of my Arnis teacher, as explained in the book "Power to the People" by Pavel Tsatsouline. While I felt the exercises were beneficial (and I really should get back into the routine once school starts), I can't ascertain that it did my knees a whole heck of a lot good.

By the way, I wear an old pair of wrestling shoes for both Arnis and Tai Chi, because I like the ankle support. Thanx, folks, for responding to my questions. It's much appreciated -- particularly knowing that I'm not the only middle-aged athlete out there still trying to stay in the game.

I had a tear in some of the cartlidge surrounding my knee in 19991-92. Happened when running to cadence with some friends in a heavy Iowa sleet/snow in January with a 70lb pack. What I suggest readers of this list do: (1)If you have any questions with regard to your knees or pain in and arround the knee I suggest that you have them scoped and if necessary deburred. The process is very quick and so is the recovery. Bone spurs and fragments that lodge in and around the soft tissue have a way of chewing up the pads that are directly under the knee cap when you go back into running or heavy lifting/squats. If you chew the originals up that God gave you - you will need to have an artificial knee put in if you let it go for too long. (2) Dittos on the leg extensions. I was told by a doctor at the Mayo clinic that leg extensions help to positively reinforce the legs natural movement through the arc that it was designed to. (3) After a warm up and stretching of the ligaments of the legs use lower reps with moderate to heavy wieghts. High reps can cause more damage...just don't overdo the weight used.

The light beam sensors like they use in stores have a fairly wide beam, who’s exact trip spot is affected by ambient light, and setting them up for distances not close to factory spec might require different focal length lenses, as well as lenses to keep the beam narrow enough. Unless one has a good grasp of optics(physics 103), in the applied sense, it can be a real and unnecessary headache. I built a light (and sound) triggered trip circuit for my camera flash to make some motion-arresting photos of breaking objects as well as duplicating Howard Edgerton’s famous milk-drop photos, so I can assure you, once the trip gap gets bigger than infrared-diode range, it becomes a mess of optical engineering I’d rather not repeat. Laser diodes are VERY cheap these days, so they would be the way to go on this method, however: As with groundwater modeling, while a 2-D approach can be tweaked to give a usable approximation, for exact data that is true to what is actually happening, 3-D systems require 3-D analysis, and this is truly a 3-D study. Also, the amount of data points availabe even with a big Frankensteinesque array of beams to swing through, is too limited to study the full range of motion and muscle action. Even keeping it 2-D, the problem is a bit more complex than F=ma. To account for the stick passing through the beam trap at an angle requires a little trigonometry. The time between any two beams must be multiplied by cosine (theta), where theta is the angle between the stick’s travel and the perpendicular. I really wouldn’t wanna be the guy sitting there with video stills, a protractor and a calculator doing all the calculations, or even the data input if a spreadsheet is used for calculations. While a professor can pimp his grad students for this laboria, grad student researchers have to do it all themselves. Your correction is almost there, acceleration is the change in velocity over the change in time a = dv/dt . (calculus notation, but simple enough an eq. to substitute delta) Velocity is found from a similar differential v = dx/dt. You can see how this limits the data points as one has to first calculate velocity from displacement, then acceleration from two adjacent velocity calculations. The formulae for differentiating and integrating these values back and forth is found in the first two chapters of any calculus-based physics 101 text so I don’t feel the need to reiterate them here, unless someone really wants them. J The beautiful thing about accelerometers, is that you can have 100 measurements (or a thousand) per second, and the computer will do all the mathematics for you, especially since integration is less fun to do by hand. It will also give you a nice graphic output of instantaneous v & a, with vectors! In regards to your email: Though the strike point force(F) needs to be measured (at various ranges), it is only for the before-and-after training results, to quantify if the analysis and derived training resulted in any improvement over a similar individual that trained by traditional methods. The real aim of this study(at least how I propose it), is the swing itself ( v and a, F having an additional variable making the calculated value different from the "real impact" value, see below). The actual impact has another variable I failed to consider: follow through. It is not just the velocity of the stick that causes damage. I think a look at the change in acceleration of the stick at impact will show who is striking through, and who is striking at. It is important to have a strike surface with constant compressibility, as this will affect the negative acceleration of the stick, and hence force measurements. This same technique could be applied to any repetitive-motion sport: baseball, golf etc. Like I said, this technology is already out there, so someone may have already done it for another sport, or a company for product development. The baseball and golf entities are quite well funded, so it may not be too hard to get a grant for this research if you do it under a different aegis. To make it a wider-ranging study( and get money to do it), encompass a few different sports, just don’t forget to squeak in Kali. --WitchDoctor ________________________________________________________________ The best thing to hit the Internet in years - Juno SpeedBand!

The best I’ve found is Bearwood products, they offer stock and custom weapons, as well as laminates that combine the best qualities of multiple woods, i.e. tough, flexible core with hard, dense outside. They use cocobolo, jatoba, purpleheart, ‘contact’ hickory, and Lignum vitae. http://www.bearwoodproducts.com/wood.htm Here’s a blank source for those with a lathe at home: http://www.gilmerwood.com/Caneblanks.htm There are many species locally known as "ironwood", however the mac daddy of them all, the densest wood is the world is known as Lignum vitae, the "wood of life". (how symbolic, from our point of view) It does not float in water, having a density of 1.37 (water = 1.0). Here’s a little info on L.vitae, for it’s applied use, see the Bearwood link above. http://www.righteouswoods.net/lignum_vitae.html http://www.cocoboloinc.com/vitae.html Someone recently posted about doing SLOW siniwalli drills with very heavy ‘sticks’ to build muscle. Wood being too light for this, one might automatically think of iron pipe. "¾ inch" threaded iron pipe, as what plumbers use for natural gas lines, has an outside diameter of approx. 1 inch, so it feels about right. Galvanized pipe wont rust like black pipe will. If more weight is needed, simply plug the handle end with cork, dowel or glue(best), fill with sand and cap the business end with a threaded pipe cap, hand tight. For greater weight, substitute steel or lead shot (from your local gun shop or sporting goods store) for the sand. Feel free to mix sand & shot for intermediate weights, as the pipe must be full to not change balance as it moves. For you extremists out there, the lead can be melted and poured into the pipe for the ultimate "heavy stix". As with any other weight training, go slow and concentrate on form. Talk about forearm pump! --WitchDoctor ________________________________________________________________ The best thing to hit the Internet in years - Juno SpeedBand!
