But pressing down and pushing up are very different aren't they, even though you use both as examples. I can hold my own body weight in a handstand quite easily but can't lift that same weight in a shoulder press. Aspirant Adam Ondras don't need to maintain that level of force for more than a second since the push effort is not continuous with a pole, it's very brief.
Finally, you're denying people's actual empirical experience with dodgy analogies.
Sooo jealous, always wanted to do a handstand
I realise i'm not going to change peoples minds, to be honest i don't want to
The whole purpose for the tread was to try and get some hard measurable data
For me, my use of hiking poles is pretty specific, no data either way is going to change my use
So i really don't have a horse in this race on either opinion
To sum up so far it seems that the main advantages offered so far
1/ Reduce impact of leg joints
The physiological aspects of what is needed to support a high proportion of your body weight on outstretched arms for hours on end interests me on this
I don't see how it's possible for the average hiker to have the upper body strength to take any noticeable support for extended periods of time
Be good to be convinced otherwise
2/ Stability
As millions of people have been walking unpaved roads for 10's of thousands of years so far i think this is more a psychological crutch rather than a real one (pun intended)
I'd also bring in the above about upper body strength being up to the task of supporting us
I do accept that with stream crossing and the like they will offer some stability though
3/ Propulsion
Way i see it so far is, nothing is for free, if we are providing propulsion with out upper body, from my admittedly very basic test my heart rate was higher using 1 pole
Be great to see some data or studies on this though
4/ Injury
As people are still getting injured using hiking poles, it's a certainty they don't stop injuries
Seems some folks are convinced it prevents some injuries though
As said, i think this is anecdotal as people do walk without hiking poles without falling over or getting injured
Also worth considering the injuries that are caused by poles when they break, certainly this is few and far between, but there are cases where people have been injured by falling on a broken hiking pole
Can't see it being possible to get any data either way on this, be happy to be proved wrong though
