With over 30 years in the fitness industry, a couple of hundred dollars spent annually on professional fitness research sites, and a few thousand dollars each year spent on attending conferences to listen to updated information, I am hardly quoting "something I heard on the web."
However, since you have ordained yourself as the ski fitness expert, the skiing expert, the boot fitting expert, the resort expert and the expert about everything in life, I see no further need for my humble comments on this topic. In fact since you have arrived, I see no further need to participate on Epicski whatsoever, so this is my final post. Every intelligent conversation that has happened on epic has been ruined by your know it all jibberish. Not only is it predictable, it's just so boring.
I used to be able to just ignore it, but now that you are claiming to be an expert and posting irresponsible advice that will set people up for very serious injuries, I can no longer look the other way. My only choice is to not be here at all. No need to comment, since I will not reply, nor will I bother to read this. As some may know, I've recently discovered that there is a small possiblity that my life my be shorter than I expected. In the case that this is true, I do not wish to spend my final days seeing a community I once loved being destroyed by the ramblings of Jonestown type pseudo-guru!
Please spare me the cliches, such as don't let the door hit you on the way out. I'm sure I won't be missed. After all, I'm sure that forum members are looking forward to reading your beautifully written posts, free of all spelling and gramatical errors, along with your ee cummings use of the perpetual lower case.
Fare Thee Well!
first: lower case is de rigeur on the 'net.
ee cummings was a hack with a gimmick...they seem to be popular with you.(smileycon)
thirdly, the angle of the upper and lower leg whilst seated on a chairlift, is rarely less than 90o. further, on a chairlift, the knees are NOT higher than the waits, as they often are on the upwardly-tilted leg extension apparatus. the legt-extension apparatus starts with the leg angle more acute than 90 o, which is where the 'shearing forces, by anti-virtue of the patella 'pulling ' up and out when the leg is at an acute angle, occurs. this is why we teach folks who squat to go only to a 90o angle in the legs, so as not to created a situation whereby 'shearing forces' exert themselves on the various support vectors of the knee.
seated position, in a chairlift, going from 90o to 180o, virtually no so-described (
: ) 'shearing forces'.
this is why this move is promoted by so many ski trainers, as it only serves to strengthen the patellar support tissues. try it, and you'll see what i mean. night and day difference form the leg-extension apparatus.
or, you can ignore the actual experience of performing the exercise, and the advice of many ski trainers and othopaedic surgeons and sports physicians, and follow your own personal guru. that's your own choice. i didn't profess to be a fitness expert, i merely passed along what was passed on to me by past us ski team orthopedes, weltcup ski coaches, many weltcup athletes, and trainers.
i've never discussed my own background in exercise kinesiology, which is merely in-the-flesh practice of advice passed on to me by these characters, and by a summer, in '83, spent living in venice, california, and working out daily with tom platz (former mr. olympia), bartering training from dr. franco colombo (past mr. olympia, then master chiropractor, and movie actor, and co-star of
'pumping iron'). i was a physical fitness freak who moved to venice after a cold, long winter of teaching, and i wanted to train at the meccas: namely, "the Pen" on muscle beach, and the original Gold's on hampton.
I met dr. colombo on the beach, and, after a few chats, got a job helping him restore a classic motorcycle, in return for free training.
good guy, for a sardinian (
not sure why you're being so thin-skinned, lisa-marie. you accused me of doling out 'dangerous' advice. that was more than just a bit offensive, as as well as erroneous.
my advice would have been more social than just dismissing my thoughtfullly -shared advice as 'dangerous'.
If you can't handle being called to task on your own attacks on the helpful advice of others, maybe you don't really belong on an internet forum.
thanks for trying to rally the troops at me, though.
lighten up, francis- it's not like someone jokingly accused you of killing a family friend.
it's only skiing, and the internet.
wake up and smell the open exchange of intelligent ideas.
