A new study [1] revealed that single-arm amputee front-crawl swimmers produce approximately 20% less propulsion (tether force) than able-bodied swimmers with comparable training backgrounds.

Dividing the world record for my disability (IPC S9) (0:54,21) by the non disabled world record over 100m freestyle (0:46,91), an excess time of 116% of the arm amputee Cowdrey compared to the non disabled Cielo results. With that, my own personal best over 100m freestyle (1:10,21) is comparable to a non disabled 47 year old swimming 100m freestyle in 1:00,34.

Generally, it takes me some 98% of the 2014 qualifying or standard time for my non-disabled age group's FINA World Masters championship 100m freestyle LC, while my handicap slows me down by 16%. So if you have no handicap and you swim 98%/116%, that is, 84% of your non-disabled age group's qualifying time, then you are just as fast as I am, relative to age and handicap. In other words, I am on par with male swimmers without handicap that swim 0:53,8 (aged 25), 0:54,8 (30), 0:55,7 (35), 0:57,8 (40), 1:00,3 (45), 1:05,8 (50),  1:10,0 (55), 1:15,1 (60), 1:22,7 (70), 1:32,8 (75) and 1:42,9 (80). Female comparative times are 1:00,7 (25), 1:03,3 (30), 1:04,9 (35), 1:07,5 (40), 1:12,5 (45), 1:17,6 (50), 1:21,8 (55), 1:26,1 (60), 1:34,5 (65), 1:39,6 (70), 1:51,4 (75) and 2:10,8 (80).

Is Karate for amputees called 'partial arts'? - [link]

 

It was alleged recently that one required "technical" prostheses in order to "participate in international sports competitions" when having a physical handicap.

Here: [http://www.myhandicap.ch/cybathlon.html] "Der Cybathlon eröffnet Menschen mit Behinderung die Möglichkeit, an einem internationalen Wettkampf teilzunehmen, was bisher aufgrund der restriktiven Regeln gegenüber dem Einsatz von Technik im internationalen Sport ausgeschlossen war" - The Cybathlon opens up participation in international competitions to people with disabilities, which due to restrictive regulations was so far not possible in international sports. (...) -- Text: Prof. Dr. Robert Riener, ETH Zürich & Uniklinik Balgrist - 04/2013

With this preposterous and arrogant statement, these individuals go too far.

The ultimate currency is respect - and this statement here is quite simply the pure opposite.

This is, superbly politely put, total nonsense. What it really means and is, that goes a lot further. But to give a short overview:

  • The Cybathlon is the last thing that we need in order to open up any possibilities as far as we can see now. There are a few roboticists, admitted, but then what. What do they "open"? Worse, since when did they open anything for arm amputees?
  • The individuals behind the text do not know shit from shinola inasmuch as international sports is concerned. They have no idea about actual regulations in sports inasmuch as participation of handicapped people in international competitions is concerned. That is obvious. Why then write new regulations? If they do not even have an idea about current ones? Is that fundamentally necessary?
  • In fact, they probably know shit about sports and prostheses. Or let us rephrase. What prosthetic arms - model, make, year, motor type, etc. - actually and factually aid and support (rather than hamper), say, freestyle sprint swimming over, say, 50 meters? Was that a rhetorical question?

They may be right about some sports and about some people with some handicaps, at certain occasions. But written as generalization as above, they clearly overstep their boundaries. There are two simple case examples that quite simply prove otherwise, and a number of further illustrative examples, without any attempt to be complete or comprehensive.
