In reply to cb294:
I'd say that any studies you do come across should be scrutinised carefully
before jumping to a conclusion.
There are many variables, task specificity being an obvious one, but here's another fundamental issue:
The upper limbs are 'guy roped' to the ribcage by muscles. These muscles not only consume energy by their activity, but also impact on the efficient action of respiration itself.
The limbs do not hang lifelessly down by your side when you walk- there is a natural and reciprocal swing as each stride is made. With this natural pattern, barring pathology, breathing remains effortless until more oxygen is required. But alter the way that the upper limbs act, and the pattern of breathing changes irrespective of the energy demands. To illustrate this, try the following:
Sitting in your chair, with the upper limbs and shoulder girdles relaxed, take a relaxed deep breath and attend to the feeling of the front of your chest expanding and the distance between your shoulders increasing.
Now reach out horizontally with your arm and try and do the same thing.
The pattern of breathing has changed. It's no longer relaxed; more effort is required.
Transfer these findings to pole use.
Many people do not know how to use poles efficiently. By pulling themselves forward, they alter the pattern of breathing to a much more inefficient pattern.
Even walking normally, without poles, each of us is somewhere on the continuum of relaxed 'abdominal' breathing- shallow, inefficient breathing. I'd offer that the degree to which (inefficient) pole use affects this is not likely to be equal across the board.
Then there's the purely practical benefit of any prop. Give a sedentary person with anxiety and poor balance some poles and the confidence factor provided by the extra propping of poles will get them further down the Pyg Track. Even though their pole technique may be rubbish and inefficient, because they're less anxious, they're less short of breath. Power output increases.
Give the 'gazelle' poles for the same task, and they may just be carrying around extra weight.
Next, irrespective of technique, there's then the poor ergonomic design of most poles. Correctly used, the design of Pacerpoles taps into the normal gait pattern and efficient breathing is readily accessed. It's not just about propelling with arms and legs. But I'm sure someone else will have a different opinion.
Look on the Pacerpoles website if you want empirical data that poles help individuals perform well when attempting long treks that require stamina. Could say that's about consistency of power output.
As to the assertion that poles ruin core stability and balance, I'm happy to meet up in Snowdonia and demonstrate that this need not be the case.
p.m. me.
