Foot and ankle structure differs between sprinters and non-sprinters

Wednesday, January 25, 2012

The skeletal structure of the foot and ankle differs significantly between human sprinters and non-sprinters, according to Penn State researchers. Their findings not only help explain why some people are faster runners than others, but also may be useful in helping people who have difficulty walking, such as older adults and children with cerebral palsy.

According to Stephen Piazza, associate professor of kinesiology, the research is the first to use magnetic resonance imaging to demonstrate that sprinters have significantly longer bones in their forefeet than non-sprinters and reduced leverage in their Achilles tendons than non-sprinters.

"We made the most direct measurement possible of leverage in the Achilles tendon and found that sprinters' tendons had shorter lever arms -- or reduced leverage for pushing their bodies off of the ground -- compared to non-sprinters," said Piazza.

Piazza explained that there may be a trade-off between leverage and tendon force when rapid muscle contraction is required.

"Imagine a wheelbarrow with 30-foot handles. Such long handles would provide you with great mechanical advantage compared to what you would get from a wheelbarrow with three-foot handles, but rapidly producing the same rotation of this wheelbarrow would be more difficult because you'd have to move the ends of the handles really fast. It is easier for your hands to generate these lifting forces when they move a few inches rather than a few feet in the same amount of time," said Piazza. "The Achilles tendons are like your hands; they are better able to lift your body (the wheelbarrow) when the handles are long enough to provide sufficient leverage without being so long that they prevent rapid force generation by the calf muscles."

According to Josh Baxter, graduate student, shorter Achilles tendon lever arms and longer toe bones permit sprinters to generate greater contact force between the foot and the ground and to maintain that force for a longer time, thus providing advantages to people with sprinter-like feet.

To conduct their research, the scientists studied two groups of eight males, for a total of 16 people. The first group was composed of sprinters who were involved in regular sprint training and competition. The second group consisted of height-matched individuals who never had trained or competed in sprinting. To be included in the sprinter group, individuals were required to currently be engaged in competitive sprinting and have at least three years of continuous sprint training. Of the eight sprinters, six competed in the 100-meter dash, with personal-best times ranging from 10.5 to 11.1 seconds. The other two men reported 200-meter personal best times of 21.4 and 24.1 seconds.

The researchers took MRI images of the right foot and ankle of each of the subjects. They then used specialized software to analyze the images. The scientists found that the Achilles tendon lever arms of sprinters were 12 percent shorter than those of non-sprinters. They also found that the combined length of the bones in the big toes of sprinters was on average 6.2 percent longer than that of non-sprinters, while the length of another foot bone, the first metatarsal, was 4.3 percent longer for sprinters than for non-sprinters. Their results are reported in the current issue of the Proceedings of the Royal Society B.

In addition to imaging the feet and ankles of sprinters and non-sprinters, the scientists also developed a simple computer model to investigate the influence of foot and ankle dimensions on muscle contributions to forward propulsion at various speeds. They found that longer forefeet and smaller Achilles tendon lever arms allowed the calf muscles to do more work, which is the goal during the acceleration phase that occurs at the start of a sprint race.

Baxter said that although the results might lead to tests that tell whether a person has the potential to be a sprinter, other factors such as body type, the dimensions of the limbs and the presence of fast-twitch muscle fibers also are important in determining if competitive sprinting is within the realm of possibility for an individual.

"In addition it is unclear whether the differences in foot and ankle skeletal structure are adaptations to sprint training or are hereditary," said Baxter. "There is evidence that human skeletal strength and form are altered by certain types of athletic training."

Piazza added that the results have implications beyond just understanding what makes sprinters run so fast.

"Our results may be useful in helping people who have difficulty walking, such as older adults and children with cerebral palsy," he said. "If we can better understand how the shapes of bones influence not only muscle leverage but also the ability to move, it may be possible to surgically alter the foot bones of people who lack mobility to help them move better. The results even might lead to screening tools for the general population as well; an MRI could determine if you are at greater risk for loss of mobility. If so, you might be more motivated to maintain your ankle strength with a strength-training program."

The MRI measurements made in the study were carried out at the Penn State Social, Life, and Engineering Sciences Imaging Center (SLEIC). Others involved with the research include Penn State undergraduate student Thomas Novack, graduate student Herman van Werkhoven and SLEIC staff member David Pennell.

Actor and comedian Tracy Morgan was hospitalized on Sunday night in Park City, Utah, where he was attending an awards ceremony as part of the Sundance Film Festival.

The "30 Rock" star?was taken to the Park City Medical Center, hospital spokeswoman Amy Roberts confirmed to NBC News.


Morgan, 43, was being honored at the Creative Coalition Spotlight Awards.

Entertainment news website TMZ quoted unidentified?sources as saying the actor "appeared extremely intoxicated during his award acceptance speech".

However,?TMZ later?posted a statement from?Morgan's publicist, Lewis Kay, which said: "Any reports of Tracy consuming alcohol are 100 percent?false. From a combination of exhaustion and altitude, Tracy is seeking medical attention."

Students create world's largest video game controller (Digital Trends)

giant-NES-controller-London

Currently on display at?London?s Liverpool Street Station in relation to the release of?Guinness Book Of World Records Gamer?s Edition 2012, engineering students Benjamin Allen, Stephen van?t Hof, and Michel Verhulst?has created a working, twelve foot long Nintendo Entertainment System (NES)?controller that?s 30 times the size of a standard controller. Weighing approximately 265 pounds, the controller requires at least two people to operate both the?directional?pad and the red ?A,B? buttons. According to Allen?s team, the planning phase for the controller took approximately five months, but the controller was constructed in about four weeks. While the buttons can simply be pushed with hands to operate NES games like Super Mario Bros and Tetris, the controller is also strong enough to handle people standing on the giant structure to jump on the buttons similar to a Dance Dance Revolution pad.

nes-ben-controllerSince operating the controller requires vastly more force than a standard NES controller, Allen?s team had to include a?light-based system within the $6,000 controller rather than the?mesh found on the original controller?s circuit board. When a button is pushed on the huge controller, a beam of light is broken and a sensor feeds the?appropriate?response into the NES. The controller is built around a steel frame and designed to look identical to the original controller except for one detail. Above the two red buttons on the right side, Allen?s team painted the word ?NEStalgia.? The three students built the controller to celebrate the?105th anniversary of their electrical engineering student association?at the Delft University of Technology in the Netherlands.

Other?Guinness Book record holders that came to view the enormous NES creation included?a Super Mario Kart fanatic that has the record for the fastest lap and the man that hold the record for most?Street Fighter competition wins. The event also celebrated the longest video game marathon in the world, a ridiculous 109-hour record set while playing?Assassin?s Creed: Brotherhood.

Costa CEO says captain misled company, crew (AP)

ROME ? The cruise captain who grounded the Costa Concordia off the Tuscan coast with 4,200 people on board did not relay correct information either to the company or crew after the ship hit rocks, the cruise ship owner's CEO said Friday as the search resumed for 21 missing passengers.

CEO Pierluigi Foschi told Italian state TV that the company spoke to the captain at 10:05 p.m. (2105 GMT; 4:05 p.m. EST), some 20 minutes after the ship ran aground on Jan. 13, but could not offer proper assistance because the captain's description "did not correspond to the truth."

Capt. Francesco Schettino said only that he had "problems" on board but did not mention hitting a reef.

Likewise, Foschi said crew members were not informed of the gravity of the situation.

Passenger video shown on Italian TV indicates crew members telling passengers to go to their cabins as late as 10:25 p.m. (2125 GMT; 4:25 p.m. EST). The abandon ship alarm sounded just before 11:00 p.m. (2200 GMT; 5:00 p.m. EST).

"That's because they also did not receive correct information on the gravity of the situation," Foschi said.

The $450 million Costa Concordia was carrying more than 4,200 passengers and crew when it slammed into well-charted rocks off the island of Giglio a week ago. Eleven people have been confirmed dead.

The Concordia shifted again on its rocky perch Friday, forcing the suspension of diving search operations for the 21 people still missing and raising concerns about the stability of the ship's resting place. But the search in areas above the waterline resumed in the evening after the ship was deemed stable.

The remarks by Costa CEO Foschi are the latest to indicate a lack of proper communication with authorities on land as the emergency unfolded.

An audiotape of the Concordia's first contact with maritime authorities has a Concordia office repeatedly replying that the ship had experienced a blackout, even though it had hit the reef more than half an hour earlier.

Italian media reported the officer on the call was Schettino, but that could not be independently confirmed.

Costa Crociere SpA, which offered support to the captain in the hours after the emergency, has now turned its back on the man who is under investigation for manslaughter, causing a shipwreck and abandoning his ship. Schettino, who was jailed after he left the ship, is under house arrest near Naples.

Costa in recent days has suspended Schettino, announced it is no longer paying his legal fees and has signed on as a civil party in the prosecution, a move that positions it as an injured party and would allow it to seek damages in the case of a guilty verdict.

Coast Guard spokesman Cmdr. Cosimo Nicastro said crews will evaluate the ship's stability Saturday morning to see if the diving operation can resume, focusing on an area where passengers would have sought lifeboats, Nicastro said.

It was not clear if the slight movements registered by sensors placed on board the Costa Concordia were just vibrations as the ship settles on the rocks off the Tuscan island of Giglio or if the massive ocean liner is slowly slipping off the reef. Salvage experts suggest it could be because of pockets of air gradually escaping.

The sensors detected that the ship's bow was moving about 15 millimeters (half an inch) an hour and the stern about 7 millimeters (one-quarter inch) an hour, said Nicola Casagli of the University of Florence, who was called in by Italian authorities to monitor the ship's stability.

The Concordia's movements are being watched since any significant shift could be dangerous for divers trying to locate those missing since the Concordia ran aground Jan. 13. An additional fear is that movement could damage tanks holding a 500,000 gallons of fuel oil and lead to leaks.

The sea floor drops off sharply a few meters (yards) from where the ship is resting, and Italy's environment minister has warned it risks sinking.

On Friday, relatives of some of the 21 missing were at Giglio's port getting briefings from rescue teams.

Casagli told Sky TG24 that some movement in the Concordia was only natural given the immense weight of the steel-hulled ship, which is being held in place by two huge rocks at bow and stern.

But the latest movements indicate it isn't stable, he said. "These are small, regular movements that are being monitored because they're going in the same direction," he told Sky.

Late Thursday, Carnival Corp., the U.S.-based company that owns Costa, announced it was conducting a comprehensive audit of all 10 of its cruise lines to review safety and emergency response procedures in the wake of the Costa disaster. The evacuation was chaotic and the alarm to abandon the ship was sounded after the Concordia had capsized too much to get many life boats down.
