Fat and Health

Wednesday, October 10th, 2012

Fat is associated with health problems, but it may not be the cause of those problems. Fat may be a defense mechanism against unhealthy eating:

If merely the amount of excess fat is the direct cause of metabolic dysregulation then removing that fat through surgery should obviously result in metabolic improvement. Unfortunately, this is not the case. In fact, an excellent prior study has shown that liposuction does not make obese individuals healthy.

[...]

Obese individuals with metabolic problems who are prescribed a class of drugs called thiazolidinediones or TZDs for short, actually grow more fat cells, get fatter, but also get healthier.

Currently, the emerging theory of why obesity is associated with metabolic disease risk suggests that it is not the excess amount of fat that results in problems – but rather, it is the inability of the fat tissue (specifically subcutaneous) to expand enough via the development of numerous, healthy adipocytes or fat cells to store all the excess calories being ingested (more details on that here).

Forget About Helmets

Saturday, October 6th, 2012

If you fall off a bike, a helmet can reduce your risk of serious head injury — but ordinary cyclists rarely fall, which is why cyclists rarely wear helmets unless forced:

On the other hand, many researchers say, if you force or pressure people to wear helmets, you discourage them from riding bicycles. That means more obesity, heart disease and diabetes. And — Catch-22 — a result is fewer ordinary cyclists on the road, which makes it harder to develop a safe bicycling network. The safest biking cities are places like Amsterdam and Copenhagen, where middle-aged commuters are mainstay riders and the fraction of adults in helmets is minuscule.

“Pushing helmets really kills cycling and bike-sharing in particular because it promotes a sense of danger that just isn’t justified — in fact, cycling has many health benefits,” says Piet de Jong, a professor in the department of applied finance and actuarial studies at Macquarie University in Sydney. He studied the issue with mathematical modeling, and concludes that the benefits may outweigh the risks by 20 to 1.

He adds: “Statistically, if we wear helmets for cycling, maybe we should wear helmets when we climb ladders or get into a bath, because there are lots more injuries during those activities.” The European Cyclists’ Federation says that bicyclists in its domain have the same risk of serious injury as pedestrians per mile traveled.

Obviously wearing a helmet to get into the bath is counterproductive, but wearing a helmet while climbing isn’t crazy.

Jerky Renaissance

Sunday, September 30th, 2012

We’re witnessing a jerky renaissance, as consumers shift toward high-protein snacks:

Sales of jerky rose 13.6% to $760.2 million for the year ended Aug. 12, according to SymphonyIRI Group, a Chicago market-research firm. That follows several years of growth, including a 13.4% sales rise in 2011.

Whether they are looking to build muscle or slim down, consumers are exhibiting a growing appetite for protein-rich snacks. In a 2010 survey of 2,000 consumers, 38% said they “always or usually choose foods or beverages because they are high in protein,” compared with 22% in 2002, according to HealthFocus International, a St. Petersburg, Fla., food market-research firm.

Meat jerky “is like Greek yogurt for men,” says Lu Ann Williams, head of research for Innova Market Insights, based in the Netherlands.

Last year alone, Innova tracked 140 “meat snack” introductions compared with 75 two years earlier. Other protein launches last year included 55 new hummus products, compared with 33 in the earlier period, and 240 new protein bars, compared with 130 earlier.

A serious hurdle, though, stands in the way of jerky’s upward sales trajectory. “We call it jerky shame,” says Tom Ennis, chief executive of Oberto Brands, of Kent, Wash., which has relaunched its jerky line with seven “all natural” products, including Hickory Beef and Spicy Sweet.

Perky Jerky’s maker was surprised to discover that 60% of its customers are women — lululemons in their marketing argot.

Slim Jim’s still focused on young men:

It’s a male rite of passage with teen guys to buy the first stick “you can afford with the change you have in your pocket,” Mr. Marple says. (The standard Slim Jim “Giant Stick” retails for around $1.30.) “It’s ‘I’m becoming a man,’ ” Mr. Marple says. But then something happens to guys in their 20s, he says. “They seek variety in snacking, and they’re moving to chips and Tostitos.”

Slim Jim launched a “man medicine” ad campaign last year, lampooning men whose increasing life responsibilities lead them to wear baby carriers and lug shopping bags. For such lapsed “menergy levels,” one spot says, “reach for a Slim Jim.”

So, young men move up from jerky to chips? Odd.

Throwing like a girl

Tuesday, September 25th, 2012

I am shocked — shocked! — to learn that girls do indeed throw like girls:

Janet Hyde, a professor of psychology and women’s studies at the University of Wisconsin at Madison, has studied the gender gap across a broad spectrum of skills. She believes that men and women aren’t as different as they are often portrayed, and she has mined data on social, psychological, communication and physical traits, skills and behaviors to quantify the gap. After looking at 46 meta-analyses, Hyde found what she defined as a “very large” difference in only two skills: throwing velocity and throwing distance.

The throwing gap has been researched for more than half a century, and the results have been consistent. According to Jerry Thomas, dean of the College of Education at the University of North Texas in Denton, who did the throwing research Hyde cites in her paper, “The overhand throwing gap, beginning at 4 years of age, is three times the difference of any other motor task, and it just gets bigger across age. By 18, there’s hardly any overlap in the distribution: Nearly every boy by age 15 throws better than the best girl.”

Around the world, at all ages, boys throw better — a lot better — than girls. Studies of overhand ball throwing across different cultures have found that pre-pubescent girls throw 51 to 69 percent of the distance that boys do, at 51 to 78 percent of the velocity. As they get older, the differences increase; one U.S. study found that girls age 14 to 18 threw only 39 percent as far as boys (an average of about 75 feet vs. about 192 feet). The question is why.

The power in an overhand throw — and in a golf swing, a tennis serve or a baseball swing — comes from the separate turning of hips and shoulders. The hips rotate forward and the body opens, and then the shoulders snap around. Women tend to rotate their hips and shoulders together, and even expert women throwers don’t get the differential that men get. “The one-piece rotation is the biggest difference,” says Thomas. “It keeps women from creating speed at the hand.” Even when women learn to rotate hips and shoulders separately, they don’t do it as fast as men.

There doesn’t appear to be a muscular or structural reason for the difference.

Mammal Radiators

Thursday, September 13th, 2012

Black bears are extremely well-insulated animals, with a thick fur coat over a thick layer of fat. This keeps them quite warm in the winter:

But once spring arrives and temperatures rise, these same bears face a greater risk of overheating than of hypothermia. How do they dump heat without changing insulation layers?

Heller and Grahn discovered that bears and, in fact, nearly all mammals have built-in radiators: hairless areas of the body that feature extensive networks of veins very close to the surface of the skin.

Rabbits have them in their ears, rats have them in their tails, dogs have them in their tongues. Heat transfer with the environment overwhelmingly occurs on these relatively small patches of skin. When you look at a thermal scan of a bear, the animal is mostly indistinguishable from the background. But the pads of the bear’s feet and the tip of the nose look like they’re on fire.

These networks of veins, known as AVAs (arteriovenous anastomoses) seem exclusively devoted to rapid temperature management. They don’t supply nutrition to the skin, and they have highly variable blood flow, ranging from negligible in cold weather to as much as 60 percent of total cardiac output during hot weather or exercise.

In humans, AVAs show up in the face, feet, and hands — which means that a refrigerated glove can cool humans quickly:

The newest version of the device is a rigid plastic mitt, attached by a hose to what looks like a portable cooler. When Grahn sticks his hand in the airtight glove, the device creates a slight vacuum. The veins in the palm expand, drawing blood into the AVAs, where it is rapidly cooled by water circulating through the glove’s plastic lining.

The method is more convenient than, say, full-body submersion in ice water, and avoids the pitfalls of other rapid palm-cooling strategies. Because blood flow to the AVAs can be nearly shut off in cold weather, making the hand too cold will have almost no effect on core temperature. Cooling, Grahn says, is therefore a delicate balance.

“You have to stay above the local vasoconstriction threshold,” said Grahn. “And what do you get if you go under? You get a cold hand.”

Even in prototype form, the researchers’ device proved enormously efficient at altering body temperature. The glove’s early successes were actually in increasing the core temperature of surgery patients recovering from anesthesia.

“We built a silly device, took it over to the recovery room and, lo and behold, it worked beyond our wildest imaginations,” Heller explained. “Whereas it was taking them hours to re-warm patients coming into the recovery room, we were doing it in eight, nine minutes.”

Overheating is a problem for athletes — and not just marathon-runners:

But the glove’s effects on athletic performance didn’t become apparent until the researchers began using the glove to cool a member of the lab — the confessed “gym rat” and frequent coauthor Vinh Cao — between sets of pull-ups. The glove seemed to nearly erase his muscle fatigue; after multiple rounds, cooling allowed him to do just as many pull-ups as he did the first time around. So the researchers started cooling him after every other set of pull-ups.

“Then in the next six weeks he went from doing 180 pull-ups total to over 620,” said Heller. “That was a rate of physical performance improvement that was just unprecedented.”

The researchers applied the cooling method to other types of exercise — bench press, running, cycling. In every case, rates of gain in recovery were dramatic, without any evidence of the body being damaged by overwork — hence the “better than steroids” claim. Versions of the glove have since been adopted by the Stanford football and track and field teams, as well as other college athletics programs, the San Francisco 49ers, the Oakland Raiders and Manchester United soccer club.

When I studied exercise physiology years ago, fatigue was described through the three energy systems: ATP depletion, or lactic acid accumulation, or glycogen depletion, etc. This new research suggests that temperature is the primary limiting factor for performance:

In 2009, it was discovered that muscle pyruvate kinase, or MPK, an enzyme that muscles need in order to generate chemical energy, was highly temperature-sensitive. At normal body temperature, the enzyme is active — but as temperatures rise, some of the enzyme begins to deform into the inactive state. By the time muscle temperatures near 104 degrees Fahrenheit, MPK activity completely shuts down.

So, cooling should improve performance, but it shouldn’t necessarily improve training, if you want to adapt to overheating.

Don’t Try This at Home

Wednesday, August 29th, 2012

Watching experts perform a skill is a great tool for improving your own abilities — but when it comes to weekend warriors watching the US Open, Tom Perrotta advises, don’t try this at home:

Pros swing the way they do and use the equipment they use because they have to.

They don’t have time to turn completely sideways and step into the ball with their front feet, so they hit most of their shots with an open stance, with their feet almost facing the net. They can’t afford to hit serves with their feet on the ground, as Evert did, so they propel themselves into the air. They barely have time to get to the net anymore, because the pace of the game is too fast and the passing shots too accurate. They need all the power and topspin they can get, and will sacrifice the feel of gut strings to get it.

Recreational players have more modest needs, ones that haven’t changed in decades: Consistent strokes that hit the ball deep in the court, patience, reliable footwork, well-placed serves and strategic acumen.

Jazzed up after two weeks of watching high-level tennis nonstop, that’s not what ordinary players want to hear.

“The worst two weeks in the life of a teaching pro are the two weeks after a Grand Slam,” says Greg Moran, an instructor for 35 years and the director of tennis at the Four Seasons Racquet Club in Wilton, Conn. “Everyone comes down with I-can-do-it disease, and you don’t want to tell them, ‘I know you can’t do it.’ “

The Last Hurdle in Sports

Wednesday, August 15th, 2012

The Olympics have always had problems figuring out who should be eligible for women’s events, Steve Sailer says, because men invented most sports as tests of manliness:

The basis of women’s sports is segregation by sex, a Plessy v. Ferguson-style separate-but-equal system. Therefore, women 800-meter runners argue that Semenya cheats them out of their rightful rewards. For example, Semenya’s participation in the Olympics cost third-place finisher Ekaterina Poistogova of Russia a silver medal and denied fourth-place finisher Pamela Jelimo of Kenya any medal.

But who cares about majority rights? Even women’s rights are a fairly old-shoe cause compared to the ascendant LGBTQIA crusade. Elite global opinion has thus rallied to Semenya’s right to the privileges of womanhood on the newfound principle that the world must accept the claim of anybody to be any sex.

What if the heavyweight boxing champion Klitschko brothers, Vitali and Wladimir, tire of fighting men and decide to enter women’s boxing in the 2016 Olympics? Should they be allowed to pummel women merely by declaring themselves the Klitschko sisters?

The Klitschko brothers would no doubt consider that unmanly and dishonorable. If you suggested it to them, they might hit you, and that could hurt.

Progressive moral preening is made plausible only by the survival of the majority’s old-fashioned morals.

Indeed, the Semenya cause is hardly about establishing principles. Instead, it’s the latest way to assert one’s sophistication over the unenlightened. It’s all part of the war on homophobia… or stereotypes… or maybe apartheid.

The elite rationalizations aren’t logical, but the mood music is irresistible: Minoritarianism has been a winning hand for so long that everybody knows you won’t get in trouble pushing even this reductio ad absurdum.

In this century, who has ever gotten ahead by demanding fair play for the majority?

Larisa Latynina

Sunday, August 5th, 2012

American swimmer Michael Phelps recently beat Soviet gymnast Larisa Latynina‘s record for most career Olympic medals. So, what was her athletic career like?

At the age of 19, she debuted internationally at the 1954 Rome World Championships, winning the gold medal in the team competition.

At the 1956 Summer Olympics, Latynina competed with Ágnes Keleti of Hungary to become the most successful gymnast of the Olympics. Latynina beat Keleti in the all-around event, and the Soviet team also won the team event. In the event finals, Latynina won gold medals on the floor (shared with Keleti) and vault, a silver medal on the uneven bars, and a bronze medal in the now discontinued team event with portable apparatus. Keleti also won six medals: four golds and two silvers.

After a very successful World Championships in 1958 (winning five out of six titles despite competing whilst four months pregnant), Latynina was the favorite for the 1960 Summer Olympics in Rome. In the all-around event she led the Soviet Union to take the first four places, thereby also securing a win in the team competition by a margin of nine points. Latynina also successfully defended her floor title, took silver medals in the balance beam and uneven bars events, and bronze in the vault competition.

Latynina won all-around titles at the 1962 World Championships, beating V?ra ?áslavská of Czechoslovakia. Still the defending World Champion at the 1964 Summer Olympics, she was beaten by ?áslavská in the all-around competition. Latynina added two more gold medals to her tally, winning the team event and the floor event both for the third time in a row. A silver medal and two bronzes in the other apparatus events brought her total of Olympic medals to eighteen — nine gold medals, five silver and four bronze. She won a medal in every event in which she competed, except for the 1956 balance beam where she came in fourth.

[...]

Latynina retired after the 1966 World Championships and became a coach for the Soviet national gymnastics team, a position she held until 1977. Under her coaching the Soviet women won team gold in the 1968, 1972 and 1976 Olympics.

South Korean Archery Training

Friday, August 3rd, 2012

South Korea dominates archery — despite its recent Olympic team performance — and relies on some unusual training methods:

Earlier this month, South Korea’s six Olympic archers held their final training session at a military base in Wonju, 71 miles east of Seoul. It was configured to look like the site where they will be competing this weekend.

Around 700 soldiers shouted, chanted and even booed during each shot as the archers competed under the tournament rules they will face in London.

“We thought soldiers would be more boisterous and distracting for the archers,” said Ban Mi-hye, a spokeswoman for Korea Archery Association.

[...]

In the buildup to London, the Korean archers have visited cemeteries late at night, undergone fitness training with Special Forces soldiers and conducted “wind-fighting” archery practice on Jeju Island, a windblown tourist island that gets some of the country’s most extreme weather.

The archers also spent a night on patrol at the Demilitarized Zone, the heavily fortified border between South and North Korea. “The exercise itself wasn’t very hard, but it made me mentally more mature by watching other soldiers working hard in harsh conditions,” said Im Dong-hyun, who set the men’s Olympic record score at the 2004 Athens Games and will be competing for the third time in London.

Then there was a six-hour walk along Seoul’s Han River during a winter night when the temperature was minus-4 degrees Fahrenheit. Twenty-one archers endured that drill, held months before the Korean team was narrowed to the six athletes who traveled to London.

Those training sessions are aimed at enhancing concentration, preparing for distractions and building a fighting spirit.

To remind the archers that they mustn’t settle for less than perfection, the country’s archery team since the 1990s has been using a cutout that features only the two most inner sections of an archery target—nine and 10 points—during training.

The team’s record suggests the extreme training works. South Korea’s female archers have won the last six Olympic team gold medals. The men’s team has won the last three.

Steeplechase

Wednesday, August 1st, 2012

The steeplechase is a wonderful example of how all the interesting variation in a sport gets refined away over time:

The event originated in the British Isles. Runners raced from one town’s steeple to the next. The steeples were used as markers due to their visibility over long distances. Along the way runners inevitably had to jump streams and low stone walls separating estates. The modern athletics event originates from a two-mile (3.2 km) cross country steeplechase that formed part of the Oxford University sports (in which many of the modern athletics events were founded) in 1860.

It was replaced in 1865 by an event over barriers on a flat field, which became the modern steeplechase. It has been an Olympic event since the inception of the modern Olympics, though with varying lengths.

Never Mind The Anabolics!

Sunday, July 29th, 2012

The irreverent marketers at Brew Dog bring you Never Mind The Anabolics!

It is about time the greatest sporting event on the planet was not sponsored by fast food companies, sugary fizzy drinks producers or monolithic multi-national brewers. A burger, can of fizzy pop and an industrial lager are not the most ideal preparation for the steeple chase or the dressage (for human or horse).

So we decided to give the athletes something that was going to make them happier and better. A way to relax before a big event and at the same time increase the chances of winning.

This is Never Mind the Anabolics. A 6.5% India Pale Ale infused with creatine, guarana, ginseng, gingo, maca powder, matcha tea and kola nut.

Why waste time training hard? This little beauty does the hard work for you. Guaranteed to boost your sporting ability in an almost completely legal way. Most of the performance enhancing additives we infused into this ale are banned for professional athletes. But winning by any possible means is the name of the game here.

Albanian Weightlifter Is Banned for Doping

Saturday, July 28th, 2012

The first athlete to be sanctioned for doping during the London Games is an Albanian weightlifter, Hysen Pulaku, who tested positive for stanozolol, an anabolic steroid:

Pulaku was selected as part of random, out-of-competition testing, according to an IOC spokeswoman. He gave urine samples on July 23, which were analyzed separately on different days. Both came back positive.

[...]

Pulaku is the third weightlifter from Albania to test positive this year, a concerning pattern, Muca said.

Stanozolol is easy to detect, but only for a few weeks:

The primary metabolites are unique to stanozolol and are detectable in the urine for up to 10 days after a single 5-10 mg oral dose.

It has a history of (mis)use:

  • Ben Johnson was stripped of his gold medal in the 100 meter sprint at the 1988 Summer Olympics when he tested positive for stanozolol after winning the final.[5]
  • Olimpiada Ivanova was stripped of her silver medal in the 10 kilometer walk at the 1997 World Championships in Athletics after she had tested positive for Stanozolol, and she was banned for two years.[6]
  • Vita Pavlysh was stripped of her gold medal in shot put at the 1999 IAAF World Indoor Championships after she had tested positive for Stanozolol. 5 years later at the 2004 IAAF World Indoor Championships in Budapest, Hungary, she won the title again only to fail the drug test for the same reason. She was again stripped of her title and banned from athletics for life.[7]
  • Liudmyla Blonska, a Ukrainian heptathlete, tested positive for traces of Stanozolol shortly after finishing thirteenth at the 2002 European Championships in Athletics and in June 2003 was handed a two year ban, whereafter she returned to the sport.[8] At the 2008 Beijing Games, she was stripped of a silver medal and given a lifetime ban after testing positive for stanozolol again.[9]
  • Rafael Palmeiro was suspended 10 days from Major League Baseball on August 1, 2005, after testing positive for steroids.[10] According to the published report in The New York Times, Stanozolol was the steroid detected in Palmeiro’s system. This came not long after he testified before the United States House Committee on Oversight and Government Reform on steroid usage in baseball, and he denied ever using steroids.
  • Barry Bonds is accused of using Stanozolol in Game of Shadows, a book by Mark Fainaru-Wada and Lance Williams. The accusations were first aired on 7 March 2006 by Sports Illustrated, which published excerpts from the book.[11]
  • Salvador Carmona, footballer, tested positive for Stanozolol in 2005 and 2006. He was banned for life by the Court of Arbitration for Sport (CAS) due to repeated drug offences. Tribunal Arbitral du Sport.[12]
  • Magnus Hedman, footballer, was charged and convicted by Swedish court in June 2009 when he tested positive for Stanozolol. At the time he was a “ambassador” for Swedish anti-steroid organization Ren Idrott (“Clean Sports”) and sports commentator for Swedish TV4. He lost both assignments as a consequence.[13]
  • Phil Baroni, former UFC and PRIDE Fighting Championship fighter, tested positive for Stanozolol following his June 22, 2007 fight against Frank Shamrock at Strikeforce: Judgment Day.[14]
  • K-1′s 2007 World Grand Prix in Las Vegas finalist Zabit Samedov tested positive for Stanozolol following the August 11, 2007 event.[15]
  • Roger Clemens was reported to have been injected with stanozolol (Winstrol) by major league strength coach Brian McNamee during the 1998 baseball season.[16]
  • 2008 Triple Crown hopeful Big Brown was reported to have been injected with Winstrol, which is legal in some states in US horse racing, by trainer Richard E. Dutrow, Jr. [17]
  • Chris Leben, mixed martial artist, tested positive for the substance after UFC 89 where he was defeated by Michael Bisping and was suspended for 9 months.[18]
  • Kirill Sidelnikov, mixed martial artist, tested positive for the substance after Affliction: Day of Reckoning where he was defeated by Paul Buentello and was suspended for 1 year and fined $2,500.[19]
  • Tim Sylvia, mixed martial artist, tested positive for the drug Stanozolol after a Nevada State Athletic Commission test. As a result, Sylvia was stripped of his title, served a 6-month suspension, and was fined $10,000. Sylvia has stated that he used the drug to shed excess body fat and lose weight. [20]
  • Cristiane Santos tested positive for anabolic steroids and as a result of the banned substance, her fight against Hiroko Yamanaka result has been changed to a “No Contest” while Santos has had her license suspended and was fined $2500. Additionally, UFC president Dana White stripped Santos of her Strikeforce 145 lb. women’s championship belt. [21]
  • Hysen Pulaku, an Albanian weightlifter, was expelled from the London 2012 Olympics after testing positive for Stanozolol on July 23, 2012. [22]

Fastskin3

Sunday, July 22nd, 2012

The international swimming federation FINA outlawed full-body, impermeable suits in 2009, but Speedo’s Fastskin3 suits use different, still-legal techniques to improve performance:

They started at the top. “The cap and goggles are the first things that hit the water, so they can create turbulence downstream in a way that affects the performance of the suit,” said Santry.

The scientists scanned athletes to produce a three-dimensional, digital avatar. They then manipulated various parts of it — squeezing here, filling in there — and used computational fluid dynamics to calculate how each change altered drag “until we found a theoretically perfect body form.”

Take the cap. The standard model is a plain silicone bowl that wrinkles at the top. Those wrinkles, like any protuberance, create drag. But shaping a cap to the average human head shape — determined by the 3D head-scanning — minimizes wrinkles.

The new cap also has room to pack hair at the nape. That fills what is otherwise a dip between the head and the back. “That dip creates a pressure drag,” explained Santry: a region of lower pressure that ever-so-slightly sucks the swimmer backward. Packing the hair into the gap decreases that drag 3.4 percent compared to standard silicone caps.

The most hydrodynamic goggles shape — a full-face mask reminiscent of Batman’s — violates FINA rules. But the runner-up takes the water flowing over the head to the eye sockets and basically attaches that flow to the face, creating an ultra-smooth “boundary layer” of water.

Smoothness is key. Boundary layers naturally flow toward regions of low pressure, which can split up the layers and create turbulence, increasing drag. The optimal goggle design is shaped like a water droplet and turned up at the temples. “It’s unlike anything on the market,” said Santry.

The goggles cut drag 2.2 percent versus other Speedo models.

The suit redesign addressed the fact that 80 percent of the drag on swimmers comes from their shape. That meant compressing fleshy areas like the thighs, rear end and, for women, the chest, all with Lycra panels sewn into the suit.

While other suits absorb water, Fastskin3 repels it. Less weight from the suit means each stroke propels a swimmer farther. So after four years and 55,000 hours of research and testing, the complete outfit reduces drag by 16.6 percent compared to standard gear, Speedo says.

That translates into an approximately .11 percent potential increase in speed. Not huge, but then the difference between winning gold and silver can be thousandths of a second. At Beijing, American Michael Phelps finished 0.01 second ahead of Serbia’s Milorad Cavic in the 100 meter butterfly. Phelps will be wearing Fastskin3, as will team mate Tyler Clary and Britain’s Rebecca Adlington./blockquote>

Strength Heaven

Monday, July 16th, 2012

The New Yorker doesn’t publish pieces on strongman competitions every day:

Early in March, I went to see [Brian] Shaw defend his title at the Arnold Strongman Classic, the heaviest competition of its kind in the world. The Classic is held every year in Columbus, Ohio, as part of a sports festival that was founded by Arnold Schwarzenegger and a promoter named Jim Lorimer, in 1989. Like its namesake, the festival is a hybrid beast — part sporting event and part sideshow — that has ballooned to unprecedented size. It’s now billed as the largest athletic festival in the world, with eighteen thousand competitors in forty-five categories. (The London Olympics will have ten thousand five hundred athletes in twenty-six sports.) Lorimer calls it Strength Heaven.

At the Greater Columbus Convention Center, that Friday morning, the main hall felt like a circus tent. Black belts in judo tumbled next to archers, arm wrestlers, and Bulgarian hand-balancers. A thousand ballroom dancers mixed with more than four thousand cheerleaders. In the atrium, a group of oil painters were dabbing furiously at canvases, vying to produce a gold-medal-winning sports portrait. The only unifying theme seemed to be competition, in any form; the only problem was telling the athletes from the audience. A hundred and seventy-five thousand visitors were expected at the festival that weekend, and half of them seemed to be bodybuilders. In the main hall, they made their way from booth to booth, chewing on protein bars and stocking up on free samples. “Yes, I can lift heavy things,” one T-shirt read. “No, I won’t help you move.”

Up the street, at the hotel where most of the strongmen were staying, the breakfast buffet was provisioned like a bomb shelter. One side was lined with steel troughs filled with bacon, potatoes, scrambled eggs, and pancakes. The other side held specialty rations: boiled pasta and rubbery egg whites, white rice, brown rice, potatoes, and sweet potatoes. This was “clean food,” as strength athletes call it — protein and carbohydrates unadulterated by fat or flavoring. The most competitive bodybuilders eliminate virtually all liquids and salt from their diet in the final days of the contest, to get rid of the water beneath their skin and give their muscles the maximum “cut.” “What do you think I’m doing here, having fun?” I heard one man shout into his cell phone in the lobby. “This is work. This isn’t playing around. My dad died, and I was lifting weights three days later. What am I supposed to do, go home and drop everything to take care of my girlfriend?”

If bodybuilders were the ascetics of the festival, the strongmen were its mead-swigging friars, lumbering by with plates piled high. “It’s a March of the Elephants kind of thing,” Terry Todd told me. “You expect that music to start playing in the background.” Todd and his wife, Jan, have designed the lifts and overseen the judging at the Arnold since 2002. (Like Terry, Jan works at the University of Texas and had an illustrious athletic career: in 1977, she was profiled by Sports Illustrated as “the world’s strongest woman.”) They take unabashed delight in the strongmen and their feats, but as educators and advocates for their sport they have found themselves in an increasingly troubling position. The Arnold, like most strongmen contests, doesn’t test for performance-enhancing drugs, and it’s widely assumed that most of the top competitors take them. (In 2004, when Mariusz Pudzianowski, the dominant strongman at the time, was asked when he’d last taken anabolic steroids, he answered, “What time is it now?”) The result has been an unending drive for more muscle and mass — an arms race unlimited by weight class.

“It’s a little frightening,” Todd told me. “The strength gains dictate that we make the weights higher, but at what point does the shoulder start to separate, or the wrist, or you get a compression fracture? We really don’t know how strong people can be.” Gaining weight has become an occupational necessity for strongmen. The things they lift are so inhumanly heavy that they have no choice but to turn their bodies into massive counterweights. “Centrifugal force is the killer,” Mark Henry, a professional wrestler and one of the greatest of former Arnold champions, told me. “Once the weight starts to move, it’s not going to stop.” Fat is a strongman’s shock absorber, like the bumper on a Volkswagen — his belly’s buffer against the weights that continually slam into it. “I wouldn’t want to be too lean,” Shaw said. When I asked about steroids, he hesitated, then said that he preferred not to talk about them. “I really do wish that there was more drug testing,” he added. “I would be the first one in line.” The same is true for most of the strongmen, Todd told me, but they feel that they have little choice: “You don’t want to take a knife to a gunfight.”

In the past five years, Shaw has added more than a hundred pounds to the svelte three hundred that he weighed at his first contest. “It gets old, it really does,” he said. “Sometimes you’re not hungry, but you have to eat anyway. Training is easy compared to that.” Pudzianowski once told an interviewer that his typical breakfast consisted of ten eggs and two to three pounds of bacon. “Between meals, I eat lots of candy,” he said. Shaw prefers to eat smaller portions every two hours or so, for maximum absorption, supplemented by “gainer shakes” of concentrated protein. (“His one shake is twelve hundred calories,” his girlfriend, a former model for Abercrombie & Fitch, told me. “That’s my intake for the entire day.”) Until he renewed his driver’s license last year, Shaw often got hassled at airports: the guards couldn’t recognize his ten-year-old picture because his face had fleshed out so much. “He’s grown into his ears,” one of his lifting partners, Andy Shaddeau, told me. “Those were not three-hundred-pound ears.”

Deep Catch vs. Scull

Friday, July 13th, 2012

In the 1960s, Indiana University men’s swimming coach, James “Doc” Counsilman, decided that lift, rather than drag, could and should provide a majority of the propulsion for human swimmers, and that the way to generate lift was to scull, or move the stroking arm through an S-curve underwater, rather than paddle in a “deep catch” style. Now the Johns Hopkins scientists who previously studied the breaststroke have moved on to studying the crawl:

They began by creating a virtual animated arm, using laser scans and motion-capture videos from Olympic-caliber swimmers. “We decided to separate the arm from the rest of the body so the we could study, in isolation, the underwater flow dynamics” around a swimmer’s arm during the freestyle stroke or backstroke, says Rajat Mittal, a professor of mechanical engineering at Johns Hopkins and a devoted recreational swimmer, who oversaw the study.

They then gathered underwater videos of elite swimmers, supplied by USA Swimming, which they categorized as displaying either a sculling or a deep-catch stroke.

The scientists ran their animated arm through multiple simulations of each stroke, requiring thousands of hours of computer time.

The result was “a bit of a surprise,” Dr. Mittal says. It turned out that lift was, as Doc Counsilman had maintained, important for efficient, and therefore fast, stroking. In all of the scientists’ simulations, lift provided a majority of the propulsive force.

But sculling did not supply much lift. In fact, it impeded both lift and drag. “Our shoulders won’t twist all the way around,” Dr. Mittal says, meaning our arms won’t lever about as ship propellers do, and the amount of lift we can create by sculling is small.

The better choice for human propulsion, he says, was the paddlelike deep-catch stroke, which actually produced more lift than sculling, along with a hefty dose of drag.

[...]

An effective deep-catch stroke requires considerable shoulder strength, which many swimmers lack, making a sculling-based stroke easier for them, at least until they develop robustly muscled shoulders.

“How you roll your body in the water with each stroke will also matter,” he says, as will overall fitness. “Sculling is less fatiguing,” so less-fit swimmers may opt to scull, he says.

But for fit, powerful swimmers, or those who aspire to become such, “my advice would be to use the deep-catch stroke,” he says.
