Actually, most swimmers at this level of competition wear two caps. Dana Vollmer, who won gold with a new world-record time in the 100m butterfly, actually lost her outer cap in the pool on the return leg of that event. Thus, the first reason; redundancy. These caps are latex rubber, which doesn't mix well with chlorine and will eventually degrade, and as ...

The two caps are also made of different materials. The inner cap is latex, which stays on the head better, but wrinkles. The outer cap is silicone, better for reducing drag. "The outer silicone cap better maintains the shape and does not wrinkle as much, thereby causing less drag," Salo told Yahoo! Sports. - Why do Olympic-level swimmers wear two caps?...

How much are you kicking? Try holding a flutterboard/kickboard/buoy between your legs and continuing the arm motion of front crawl. This does two things. Removes the leg muscles from the equation Keeps your legs up, which makes swimming MUCH easier. The main trick in efficient swimming is to learn to swim downhill. You want to 'Press the Buoy' which is ...

This might seem a stupid question, but are you breathing out when your head is underwater? Most swimmers that I see struggling to catch their breath are holding their breath when their head is in the water, and then trying to both breathe out and in when they turn their head above water. There's not enough time to do both in crawl and they inevitably ...

It is for speed- if you have your goggles on over your cap it upsets water flow, so the second cap over that holds the goggles safely on and streamlines the head. Sure, it's an infinitesimally small benefit, but at that level it is important. Additionally, some sports manufacturers make some specifically to be worn like this to reduce drag further.

A good bet is that this is probably caused by being nervous, and you might be hyperventilating. Given your fitness level, there's probably not a physical reason for getting out of breath - and I bet your breath very quickly returns to normal when you grab the side of the pool. The good news is that this is 100% fixable - and you've already taken a big step:...

Since crickets were chirping in here I did a little more research, and found that chlorine itself will cause irritation and irritated sinuses are more likely to become infected. This seems true to me, because I don't often hear of athletes getting infections from long open water swims in rather dirty water. Ear and nose plugs are not very useful while ...

When I started swimming seriously, about 4 years ago, I struggled with exactly the same problem. It took me a long time to break the 100m barrier for front crawl, doing bi-lateral breathing. Uni-lateral breathing was a little better but I still struggled with a sensation of panic and being out of breath. Once I had broken the 100m limit, suddenly it became ...

The reason the fastest swimmer is placed in the center lanes is because it's believed to be the "coveted" lane. This is due to the fact that from lanes 4-5, you have the greatest visibility of swimmers in the other lanes. This is an advantage because in competitive races, athletes are known to perform better when they realize a competitor is close. Also,...

For short course triathlon as you suggest it is not worth worrying this much about shoes. Either use pedals with clips and straps (cages if you will) and ride in your running shoes, or else switch shoes in transition. For your runners, they sell stretchy laces so you can slip the shoes on, no need to retie the laces. This will minimize transition time. ...

This is clear in the rules of swimming. For example, take the USA Swimming (official web site) rules, which follow from FINA. In section 102.24, Timing Rules one finds: 102.24 TIMING RULES Requirements for Official Time A. Performance Requirements (1) An official time can be achieved only in USA Swimming sanctioned or USA Swimming ...

Ultimately this goes back to David Berkoff, a US Olympic backstroker in the '88 and '92 games. He realized that by dolphin kicking underwater he could go faster than swimming on top of the water (no surface tension to slow you down). Using this technique, he was able to set several world records and an NCAA championship. The problem was, this underwater ...

It used to be that lanes 1 and 8 were considered slower due to reflected waves off the side, but modern pools have wave reduction systems so this is no longer the case.

I'm in a similar situation, albeit I only run half-marathons and bike up to 60km. When I started swimming I had the exact same problem, that I couldn't breathe according to what felt a good swim effort. In the end I relaxed my swim speed as well as allowed my self to breathe every time I pulled back with an arm. I really focused on my breath and feeling ...

It is definitely a good idea to take a day in the week to rest. Just like someone who lifts during the week or has a serious workout regiment, a rest day is necessary for the muscles to recover and gain strength.It is a good idea for you to take that day to let your body re cooperate. THis should definitely help you gain strength in your arms and legs for ...

To be fair, David Berkoff didn’t quite invent the underwater swimming dilemma, but he had a large part in making it an enough of an issue that FINA had to institute the 15m rule. Pre-dating Berkoff was a swimmer named Jesse Vassallo, who in 1976 was lined up against future Olympian John Naber. At a considerable height advantage, Vassallo figured he could do ...

You should be swimming facing directly down or slightly forwards. If you can imagine an axis going from the top of your spine straight up through the top of your head then when breathing you should rotate your head about this axis. In other words you don't move your head left or right, simply rotate your head to breath. No matter how far you have to reach ...

I'm pretty sure it shows the world record pace, rather than the position of the holder at that point in the race - i.e. it advances at a constant speed. Unless the TV company had exact positional data on every world record swim, it would be impossible to plot the position of the swimmer. The only reference I can find is at http://forums.usms.org/archive/...

The circles are actually the result of a purported recovery practice called cupping. Practitioners claim that it aids in blood flow and recovery to various body parts. Considered a form of alternative medicine, there’s no study evidence for its efficacy. It seems to be the latest fad for high level athletes.

Ok, I found it. It's a term relating to triathlons and it's called an Australian Exit.

Nimrod Shapira Bar-On came second in his qualifying heat in the 200m freestyle, Shapira Bar-On had put Jonathan Koplev‘s name on his swim cap – Koplev was supposed to participate in London-2012 Olympic but had his appendectomy burst and made ​​him stay home (Source). The first reason you can think about is a gesture of Nimrod Shapira Bar-On to Jonathan ...

That sounds like too much swim training to me for a 7-year-old. My kids do competitive swim training and I can't imagine getting them up for a 5AM start ! For one thing, what time will she to bed at night ? Getting enough sleep is just as important, if not more so, than the 3 elements you mentioned. It seems that young swimmers are pushed very hard at an ...

Without elaborating on the technical differences, because I'm probably not qualified to give a full answer in that respect, I'll answer the first part. The reason butterfly has a higher peak speed is that you are pulling with both arms at once. When pulling with both arms, you're going faster than the one arm pull of freestyle. When recovering both arms, ...

When you allow someone to complete their entire swim as a glide you do a few things that are not considered good for the sport You emphasize swimsuit technology over strength and speed Emphasizes lung capacity over strength and speed Don't use half the body Swimming is a total body sport about strength and speed. If you allow someone to go the whole way ...

When I started swimming I had the same problem. I come from an ultra running background so I had very little flexibility in my ankles and poor technique. The following worked for me: do lots of stretching to get some flexibility back in my ankles. You must try to point your toes to the back and not down; Take a look at this page http://www.feelforthewater....

It comes down to a couple things. Ankle flexibility is huge. Your ankles are what creates propulsion in your kick. Not your thighs, not your calves. Your ankles. The more flexible they are the more water they push back (and not down, as is typically practiced). Kicking and swimming with a narrow profile. Most swimmers feel like they have to kick big and ...

I use a tiny device similar to this: You push the button at every turnaround. The device counts the lengths and records the time for each. You can view the times, as well as the average etc, at the of the session. Some of the functions (e.g. pausing the clock) are a little awkward to use on my lap counter. However, I don't find this to be a major ...
