The secrets to making a sleeker, speedier swimmer
Science turns to nature and high-tech materials for cutting-edge suits

High-tech swimsuit mimics the wings of a kingfisher

From practically naked to full-bodied, in the four years since the 2000 Sydney Olympics has passed, there has been a radical shift in swimsuit design for Olympic swimmers. Advances in fabrics and stitching have allowed swimmers to wear suits that reduce drag even more effectively than human skin. This year's summer games in Athens will be witness to the never-ending evolution in developing the perfect swimsuit - one that moves like a second skin and provides the lowest water resistance possible.

1. Hi-Tec → Hi-Tech
2. 以下の引用符 ' ' はなくてもよい。
3. Let's use "water" rather than "fluid" since the suits are being made to deal with, and only with, water. Also, "water resistance" rather than "water-resistant," which means 耐水。
4. more → greater
5. stillは不要。

1. 出だしの部分はa little wordy. Swimsuit design for competitive swimmers…とする。
2. I don't think the swimsuits were being made close to human skin. Four years ago elite swimmers were wearing very little fabric; they were almost naked. Now, the trend has gone in the opposite direction. These new swimsuits are known as "full-body" suits.
3. going through evolution → evolving

1. High-Tech
2. Tiny grooves 0.5 mm wide are etched at an interval of 1 mm to reduce water resistance
3. The 2000 Olympics was a turning point for the swimsuit industry's competitive swimwear divisions. OR, the 2000 Olympics was a turning point in the evolution of competitive swimwear.
4. mimic bare skin, but now they are pursuing
   Let's make this a little less wordy… "Previously, the goal (aim) was to make a swimsuit…"
5. The major reason
6. with less drag
7. thanks to state of the art fabrics
8. greater mobility

2. a smoother bodysuit は、a bodysuit smoother に訂正。
3. 以下の“”は削除。また、””全体は単に a full-bodied suit とすることができる。
4. The 2004 Olympic Games と the を追加。

1. First, love the word "skimpy"! Second, maybe you want to make this a subtitle since it doesn't stand as a complete sentence by itself.
2. I thought most Olympic swimmers in 2000 wore very little fabric, but now the trend has changed to full-bodied suits.
3. I wonder if we should use present tense since these suits and technologies are still very new.
4. I would use "sleek" rather than "smooth" although the nuance is subtle. However, let’s stay away from comparing swimmers to "squid". It does not connote the elegance or sleek design of a dolphin. Yes, squid are remarkably flexible swimmers but unfortunately, most people are grossed out by them.

Sports apparel maker Asics unveiled on June 29 a new swimwear that features built-in water-repelling processing. "We've managed to incorporate the same water-repelling filaments you find in a fishing rod into the swimsuit", noted one of the team's project engineers.

1. 2004 は不要。We can assume it is this year unless otherwise mentioned.
2. "Novel" is probably not the best word to use here. I think "cutting-edge" or "high-tech" or "state-of-the-art" are more powerful words to describe this technology.

1. 2004は削除。We can assume it’s this year unless otherwise noted.

Also getting into the fray is sportswear designer, Descente, as they announced the latest product in their "Arena" brand of swimwear, the "aile - bleue" swimsuit, its coloring and sleek form inspired by one of nature's most adept divers, the kingfisher.

Mimicking the fine protrusions that project from the wing of a kingfisher, thus making it such a natural in water, are incredibly tiny ceramic beads weaved into the suit's fabric. These microscopic irregularities throughout the suit, called the "bead print", form a diamond-like pattern that can adjust water flow dynamics, reducing drag by 5.5% when compared to conventional swimwear.

Q: Is this usage of "such" OK?
A: "Such a natural" is correct and common usage.

For example, "She is such a natural in the water that I wonder if she wasn't a mermaid in another life."

It is a way to describe an ability so fine-tuned, so well-crafted that it must be innate, that is natural.

1. Aile-Bleue → the Aile-Bleue swimsuit
2. feather → feathers でも、feather だと wing 以外の場所の feather も入ってしまうので、wing (または feathers of the wing) のほうがよい。
3. kingfishers → a kingfisher
4. Asperities is a really high-level word. Perhaps "projections" or "protrusions" would be better. Technically, it is OK.

Using the same high-tech computer analysis found in F1 auto racing and avionics, the sport of swimming is now using this advanced technology to study the incredibly complex motions of water as it interacts with a competitive swimmer. New style, full-bodied suits that feature a blend of flat-seam stitching and "sharkskin" fabric allow swimmers to cut through the water more fluidly than normal fabric, reducing drag in male swimmers up to 4% and female swimmers about 3%.

Q: Repetition of 'using' seems somewhat strange.
A: You are right. I should have avoided using "using" twice in the same sentence. Perhaps I could have started the sentence with "From".

Q: competitive → competing?
A: "Competitive swimmer" is acceptable, although I can see where the confusion lies. I wanted to clarify that this computer analysis is not being done on just any swimmer, but on elite, cream-of-the-crop swimmers. Those competitive swimmers are going to generate completely different dynamics than just an average swimmer, and if the money and research being poured into this computer technology is going bring any results, then the very top, competitive swimmers need to be analyzed. Perhaps it wasn't the best choice for that particular sentence.

1. Who are "They"? もちろん訳出部分以外の和文を読めば分かるが、このように抜き出して訳す場合、誰だか分からない。Researchers... などの別の単語を使うなど工夫するべき。
2. FS2も訳出以外の和文を読めば分かるが、(1) と同様。This is the first time you mention “FS2” so the reader probably needs an explanation as to what it is.

1. Who are "They"?
2. get along with → regulate / adjust
3. shark-skin-surface → sharkskin-surface

1. race car
2. water flow
3. the 削除。
4. water resistance
5. for men's full-bodied suits
   I think the word choice here is a little confusing. The cutting method relates to the cut of the fabric in the suit. You use the verb "tailor" for regulating water flow, but "tailor" is usually used in clothes. Perhaps you would want to rewrite it as "The resulting cutting method tailors the suit to regulate water flow by combining scaly, sharkskin-like material with flat-seam stitching to successfully reduce the water resistance…"
