Pros and Cons of New Omega Backstroke Starting Platform
Take Home Points:
1. The new Omega backstroke starting platforms will likely benefit swimmers by at least 0.2 s.
2. The new Omega backstroke starting platforms may provide more safety than the traditional start
3. Omega backstroke starting platforms are positively received by Olympic swimmers.
Not too long ago, FINA approved a new Omega backstroke starting platform. This device has not undergone vigorous testing, but has received backing from most countries including USA Swimming, despite a lack of information about the costs and dimensions of this device.
Jeff Cummings of Swimming World Magazine, wrote a short piece on this device in June (EXCLUSIVE VIDEO: TESTING NEW BACKSTROKE PLATFORM AT USA SWIMMING NATIONALS) and notes he doesn't "want to go back to doing a backstroke start without it again (Cummings 2013)". Now, before praise is given, an investigation and consideration of the ramifications of these platforms is necessary to prevent potential flip-flopping and contradiction like the Fastskin suits. This article can not provide all the pros and cons with this equipment, as repeated testing and trials are necessary for that, which have not been done. This is what occurred with the Fastskin suits, a new product was brought to market, approved by the governing bodies, and eventually banned due to poor foresight. Once again, this foresight is impossible without proper testing.
Cons
For example, the omega track starts (OSB 11) were approved by FINA and now we know the OSB11 improves starts by ~0.2 seconds (a 4% improvement) (Biel 2010; Honda 2010). This significant improvement is massive in a 50 - m freestyle race, potentially skewing the record books, yet few discuss this advantage like the Fastskin suits. Now, it is obvious the Fastskin suit is far different than either of these new starting platforms. However, it is clear these technological advancements will increase swimmers times. These time improvements must be taken into consideration, as many swimmers will go best times and the sport will undergo further progression.
Pros
Now, there are benefits which must also be considered, the first being safety. Personally, I've never heard of anyone getting hurt during a backstroke start, but many swimmers do slip. This slippage has the potential of causing hyperextended knees and/or hip subluxations, both likely rare occurrences. Another benefit is the comfort of the swimmers. Mike Unger of USA Swimming noted Olympians such as Ryan Lochte and Matt Grevers "loved the blocks", allowing them to fully concentrate on the start (Unger 2013).
Summary
Further testing should be performed on new swimming technologies should be performed before implementation. This testing can help prevent "flip-flopping" of rules, regulations, and records. At this time, these starting platforms appear to benefit the sport, but expect faster times and a few more unknowns to unravel at major competitions.

| Nevem, če prav razumem ampak meni se zdi, da je to kot neko naslonjalo za noge pod vodo. Čeprav tega nikoli nisem probal, jaz sem ZA, ker na štartu pri tehniki na hrbtno je edini problem, ker ti lahko zdrsnejo noge na štartu in to se lahko še kako pozna pri časih, in še posebej v kratkih razdaljah. |

Kaj pa ta način, kakšen se vam zdi ?

Meni se zdi tole veliko boljše, kot pa štartni blok OMEGA, ki je naveden zgoraj.
