: Hi Frank , thanks for your correction.
: I hope you enjoy the way we discuss on the Forum. Open but critical.
No one can ever hope to improve if all they hear is how smart they are. Critical is good as long as it is intellectual criticism and not mean natured.
: How about the restriction or the enhancement of certain muscles in certain body position to avoid turbulance in airflow.
: Think on specific breathing technique in people with scoliosis. The Turbulance may be caused not by specicifc tissue changes like in emphysema , but by mechanical bending of upper airways..
This is rarely an issue except in the most severe cases. These people are not elite athletes.
: This may also occure in extreme aerodynamic positions in certain sports like cycling. ( Front wheel lower as we had a few years back.( perhaps in rowing - mechanical pressure or cross country skiing )
No, the airways are ot restricted in these sports. The diaphragmatic motion could be restricted from increased intraabdominal pressure or chest wall motion could be restricted, but the airways themselves are hardly ever affected by positioning.
: The extreme position actual produces a mechanical pressure on some of the airways and reduces the amount or restricts the amount of air being able to reach the actual exchange place in the lungs.
No, extreme positioning can restrict the movement of the diapraghm or chest wall but does not restrict airways.
: Now there is a lot other " restiction " out there and I am sure we will find out more.( O 3 hazard in Athene during the olympics for all athletes reading here may be something to think about )
: Thanks once more for visiting the Forum and thanks for your great invention. We would not be there with some of our athletes without you invention. We may actually be your biggest Fan , because of you we steady find out some more " restriction " and can work on our weakness to improve.
: I hope you will see in Athene some good results out of this work and you can be proud to be a part of it.
I currently expect a minimum of 4 golds medals at Athens will be PowerCranks trained. Most will be in cycling or triathlon. There could easily be 6-8 and I am working on getting more, especially in track and field. Unfortunately, nothing we do can guarantee a specific result in competition.
