Goggle Straps Causing Drag?

Goggle Straps Causing Drag?

Mark Sptiz
Mark Spitz – Olympic Gold Medalist

It was not that long ago when Mark Spitz won all of his gold medals wearing only a nylon brief swimsuit. Goggles, swim caps, and even shaving were not necessary to beat his competition. When I say he did not shave, I am not talking about shaving his body down, I am talking about just shaving his mustache. It makes me wonder if I put on a LZR suit, goggles, and a cap — would I be able to beat Spitz?Goggle straps worn outside of the cap add about 2 – 3 per cent drag. So swimmers should always make sure that their goggle strap is inside the cap when they race and not on the outside.The difference in winning and losing a race is now so small that swimmers

everywhere are doing anything they can to reduce drag and increase speed. We have seen the difference that caps make and the new Speedo Aqua V cap is the next technological advancement in head wear. By using different densities of silicone, the Speedo Aqua V Cap is not only hydrodynamic, but also remains comfortable and lightweight when being worn. The multi-density design reduces drag 5% by eliminating wrinkles and holding its shape during competition. Speedo has even designed this new swim cap to allow your goggle straps  to become even more hydrodynamic under the cap.

The amount of increase in drag may not seem like a lot, but the small changes in drag have big impacts on ultimate performance. If they didn’t the Speedo LZR wouldn’t have that many world records under its belt already.

The First Step in Regulating the Speedo LZR and Blue Seventy Nero

The First Step in Regulating the Speedo LZR and Blue Seventy Nero

 

FINA meet this weekend and drafted the Dubai Charter which is the first step in regulating the controversial swimming suits like the Speedo LZR Racer, TYR Rise, Blue Seventy Nero, and the Aqua Zone Renegade. FINA is laying the ground work for new regulations that will start popping up in the next few months and years to come. The idea is to insure that the sport of swimming remains fair and that the playing field or pool is equal for all swimmers.

 

 

DUBAI CHARTER on FINA requirements for swimwear approval

As the world governing body for aquatic sports, FINA has the authority and responsibility to issue regulations applying to its five disciplines. This includes the determination of the specifications applying to sport equipment. In the context of the discussion in connection with swimsuits development and their alleged impact on sport, FINA reaffirms that it will continue monitoring the evolution of the sport equipment with the main objective of keeping the integrity of the sport.  

In doing so, FINA wishes to recall that the main and core principle is that swimming is a sport essentially based on the physical performance of the athlete. This is the fundament which FINA has and will continue to preserve as its main objective and priority. FINA brings together athletes from around the world to compete on equal conditions and thereby decides the winner by the athlete who is physically the best.  

This does not however imply that swimming, like all other sports, should not integrate the natural progress and improvements in technology where this helps, bettering the conditions under which the athletes compete and optimising their athletic performances. 

FINA also acknowledges the significance of the contributions manufacturers are bringing to the sport at all levels, including to the federations, athletes, coaches and event organisers. This co-operation is essential to continue to develop and remain a major sport worldwide.  In a rapidly evolving world, regulations need to progress as well to address new emerging issues. Before any discussion arose, FINA had initiated a process in view of adapting the equipment regulations. To improve their quality and credibility, FINA has not only consulted the manufacturers but has also sought the support of independent scientific experts of worldwide reputation who will notably assist in the determination of meaningful tests.  

With the support of independent experts, FINA will set up a long term monitoring project with the mid/long term objective to allow an ongoing control on equipment development.  

The FINA Bureau, after considering the conclusion of the meeting with the Swimsuit Manufacturers held in Lausanne (SUI) on February 20, 2009, where the full support from the FINA Athletes, Coaches and Legal Commissions was also received on this matter, has decided to revise the requirements for swimsuit approval with the aim of making them more clear, simple and transparent. 

1. Amendments to existing FINA requirements for swimwear approval (valid until December 31, 2009) 

a. DESIGN: The swimsuit shall not cover the neck and shall not extend past the shoulders nor past the ankles. 

b. MATERIAL:  

  • i. When used, the material shall follow the body shape; 
  • ii. The application of different materials shall not create air trapping effects. 

c. THICKNESS: The material used shall have a maximum thickness of 1 mm. The measurement method is in accordance with ISO Standard 5084 for textiles. 

d. BUOYANCY: The swimsuit shall not have a buoyancy effect of more than 1 Newton (100 gr). 

  • The value to be observed applies to all swimsuits sizes. 

e. CONTROL: FINA has established its own independent control/testing programme. Scientific testing on thickness and buoyancy will be conducted by a neutral team led by Prof. Jan-Anders Manson, from the Swiss Federal Institute of Technology (EPFL) and Laboratory of Polymer and Composite Technology. 

f. CONSTRUCTION: Any system providing external stimulation or influence of any form (e.g. pain reduction, chemical/medical substance release, electro-stimulation, or others) is prohibited. 

g. CUSTOMISATION: All swimsuits of an approved model must be constructed in an identical fashion with no variation/modification for individual swimmers from the samples submitted for approval. Any modification before use is prohibited; it is clarified that an adaptation of size does not constitute customisation.  

h. USE: The swimmer can only wear one swimsuit (FINA Rule GR 5.3). 

i. SWIMSUITS TO BE SUBMITTED: All swimsuits to be used during the period of application shall be submitted, even if previously approved. The only submission deadline under these rules is March 31, 2009. 

j. APPROVAL: Approvals issued under these rules remain valid until December 31, 2009. Manufacturers must indicate the approval on the product in use through a method to be implemented by FINA. The purpose is to check that the swimsuits used in competition are approved models.  

In addition to the amendments valid until December 31, 2009, the FINA Bureau approved the following: 

2. FINA requirements for swimwear approval (valid from January 1, 2010) 

a. SWIMWEAR SUBJECT TO APPROVAL: Any swimwear used in FINA competitions and Olympic Games shall comply with these new rules and shall be a model approved by FINA in accordance with these new procedures. It is further clarified that results achieved in other competitions may only be recognised as world records by FINA if approved swimwear has been used. 

b. PERMEABILITY: In addition to the thickness and buoyancy scientific independent tests already included in the previous requirements, FINA will define the use of non-permeable materials based on a ‘permeability value’ test. The non-permeable material can only be used for a maximum 50% of the total surface of the swimsuit for full-body models. For these models, the maximum surface of non-permeable material to be used on the upper and lower part of the swimsuit shall be respectively 25% on each part. Non-permeable material shall be distinguishable.  

c. SUBMISSION DATES: The first submission deadline under these rules is November 1, 2009, followed by a submission on August 1 every year (example: August 1, 2010; August 1, 2011). Submission to approval 12 months in advance of the forthcoming FINA World Championships or Olympic Games. Moreover, the approved model shall be available on the market at least 6 months prior to the forthcoming FINA World Championships or Olympic Games. 

d. LIST OF APPROVED MODELS: FINA will publish a list of approved models. The publication is without prejudice to the fact that criteria and conditions of approval must be effectively met by products in use.  

e. APPLICATION: These new rules are applicable from October 1, 2009. They are applied to swimwear to be used in competition from January 1, 2010. Further amendments, if necessary, shall be issued by the FINA Bureau.  

3. FINA Monitoring Programme on swimwear

FINA will continue monitoring the evolution of the sports equipment and watch innovations in shape, material and other elements which may need to be addressed. 

FINA will consult with its National Federations, its Athletes, Coaches and Legal Commissions, Swimming Committee and manufacturers on any further developments in this respect. 

FINA will consolidate the independent scientific support from Jan-Anders Manson and his team, from the Swiss Federal Institute of Technology (EPFL) and Laboratory of Polymer and Composite Technology.

Finding the Correct Swim Cap

Finding the Correct Swim Cap

Most people new to the sport of swimming think that swim caps just keep your hair dry, however they very rarely keep your hair dry at all. There are a few reasons to wear a swimming cap, it keeps your hair out of your face, it protects your hair from getting damaged by pool chemicals, and for the competitive swimmer it helps to reduce drag. Swim coaches and spectators like the swim caps so that they can easily spot their swimmers in the water and on the blocks.

Types of Swimming Caps:
Swimming caps come in all kinds of colors and fun designs, but the most important difference between swimming caps is the material.
Latex Caps:

 

These are the thinnest and cheapest and also the most common types of swimming caps, but also the least comfortable and most fragile. If you are allergic to latex, these are obviously not an a good idea for you. Latex swim caps will pull your hair more than any other type of swim cap. This is why so many people do not like swim caps, because they have only used a latex cap before. The price is the major reason why people still buy the latex swim caps. For around $3 you can purchase a latex cap. Many swim teams choose latex swim caps with their team logo or name. These custom latex swim caps are far less expensive than the alternative, silicone caps. Click here to see more latex caps.

 

Silicone Caps:

 

Over the past few years silicone swim caps have emerged as the best option for swimming caps. They are much thicker than latex caps and much more durable. The silicone swim caps are easy to put on without pulling your hair as much and they don’t break as easily as latex caps. They are also more expensive, around $10-15 at sporting goods stores, but you can find them for alotless online. The cheapest I’ve seen them is at djsports.com
Lycra Caps:
Lycra swim caps are made of swimsuit material. The only thing they can do for you is keep your hair out of your face. Some people like them because they are easy to get on but for almost the same price as a silicone cap they only last about a month. This is not a very good investment of your money.
Refuse to Fade

Refuse to Fade

Are you tired of your swimsuit fading and spending money replacing swimsuits every few weeks or monthly? Then you should look into getting a polyester swimsuit the next time you head down to the swim shop. Taking advantage of a unique polyester and PBT blend, the TYR Durafast swimsuits fit and perform like traditional Lycra swimsuits, but they last three times longer. The combination of polyester and PBT provides chlorine protection, sun resistance and quick drying capabilities to prevent color fade and degradation. But it’s not just a durable practice suit. Durafast’s remarkable fit and shape retention is an engineering treasure; a long-lasting poly suit that fits and performs so well you could race in it to.

Is that a Mermaid?

Is that a Mermaid?

Okay, maybe mermaids are fictional…  If you didn’t know any better though you would swear Nadya Vessey was the real thing.  Nadya’s longtime wish to become a mermaid came true thanks to New Zealand special-effects company Weta Workshop.  Nadya now has a fully functional mermaid tail with an attached suit for when she hits the water.  As of now there is no word on whether FINA will approve the tail for competitive use.

Don’t expect to get your hands on your own mermaid tail since Weta Workshop isn’t expected to put them up for sale anytime soon.  However, you can get similar training effects with the Finis Monofin.  The monofin is a great training device that benefits all swimming strokes and overall aquatic fitness.  It is ideal for lengthening the stroke, improving body balance, and core muscle conditioning.  Also, the Finis Shooter Monofin provides the same benefits while allowing for a quicker kick pace.  Monofins are available at D&J Sports, mermaid suits sold separately.
