Blood Flow Restriction/ Kātsu Training

[Gyakuto]

Is the cuff properly aligned and designed for the much larger leg? (assuming this is the "lower limb" you refer to)

Yes it is. The cuff is designed for upper- (arm) and lower- (leg) limb and thus is a bit cumbersome to apply to the upper limb with one hand!

It is a well known systematic error in all cuff based blood measurement that using a too small cuff, tend to overestimate the blood pressure.

Yes it’s an issue we’re made aware of in clinical practice, especially with increasingly obese individuals. The cuffs are much narrower than clinical pressure cuffs so they tend to bulge at the sides as the pressure was pumped up on the lower limb. I’ll use reported data for lower limb pressure and adjust it by feel. Not ideal but needs must.

It seems the issue was extravascular compression from isometrically contracted leg muscles. Measuring the pressures while lying on an unloaded leg gave more normal values for limb occlusion pressure.

Today I tried using the two pairs cuffs on my arms and legs simultaneously. There was a marked increase in my respiratory rate, startlingly so! I’m quite enjoying blood flow restriction training!

My sensei performed this on me - except he called it a "choke." I almost passed out, but I must admit it was enjoyable. To be honest, I'm not sure about this "katsu" thing - sounds like something Bruce Lee would have tried along with his muscle electrostimulation, extreme training, and drugs. Those seemed to work out well for him.

upper limb occlusion pressure (LOP = 155mmHg) with a doppler. 60% of that is 93mmHg

Just what I was thinking . One of the graphics from your book mentioned "laminar flow" and "shear stress." I studied those in my postgrad class on glaciers. Didn't understand that either. I'll just stick with hojo undo and kata.

I think you should keep this sort of thing between you, your sensei and those websites you like to frequent.

Yes some people don’t like a new idea that have been around for 50 years, has a huge body of peer reviewed scientific evidence to support it’ efficacy in a range of paradigms (some of which I’ve posted here for people to read), is being increasing used by Olympic athletes and the UK’s penny-pinching national health service is looking to roll out to actually save money in rehabilitation costs. These ‘new’ things are frightening and challenge our way of thinking and we cannot have that - after all, ‘doing the same thing over and over and expecting different results is the definition of…’ I can’t remember the rest of that quote.

Hmmm…you’re not painting a very good picture of your ability to understand information and thus the credibility of your opinion

I'll just stick with hojo undo and kata.

Yes, stones on the end of sticks sounds perfect for you, but you might want to check this new idea called ‘progressive weight training’…I’ve heard great things about it.

Yeah, I'm just a lump of coal trying to stay in shape and develop my karate. I train weights a minimum of 3 hrs/wk and just got back from the park practicing some weapons kata. Don't plan on entering the Olympics and have no need of electronic equipment or mathematical formulas to improve my performance. I'm quite satisfied with my current regimen.

Technical advances are fine. My car's windshield has "heads up" digital display and sensors that automatically turn on the wipers when it rains (how did I ever survive without those?). But perhaps better to have invested into better plastic to keep the folding center armrest from breaking. Now that's a 'frightening...way of thinking."
