Kukla's Korner Hockey

Next week, a group of businessmen and a podiatrist will unveil, at the Hockey Hall of Fame, what has been dubbed a “revolutionary” step in the protection of athletes’ heads – the noggin, a form-fitting black skull cap outfitted with cushioning gel packs that athletes can wear under their helmets….
But one word not likely to be uttered at Tuesday’s press conference is “concussion” – even though the company previously claimed in promotional material that wearing the $29 polyester and spandex cap under a helmet “significantly reduces the chance of concussions and mild traumatic brain injuries.”
The noggin, some neurologists and biomechanical engineers say, is the latest example of an overhyped attempt to solve hockey’s concussion epidemic with protective equipment – a trend preying on parents’ worst fears.
Here’s the website for the Noggin if you want additional information.

Reebok-CCM dubs its next-generation gear “Crazy Light.’’ The Crazy Light shoulder pads weigh 750 grams. Traditional shoulder pads weigh 1,000-1,500 grams. The pads feature a softer material called UFoam instead of hard plastic.
The line is undergoing testing. Select players, including Reebok-CCM endorsers, tested the new pads in the 2011-12 season. The advantage to the Crazy Light line, according to Dube, is how it protects the wearer while also spreading out impact.
“It’s more diffuse,’’ Dube said. “There is a reduced stress of impact. It also absorbs more impact. It reduces the angular acceleration, which is key.’’
According to Shanahan, some players have tested the softer shoulder pads. Like Dube, Shanahan does not have a timetable as to when such pads will become standard.
“We’re going in a different direction now, where we’re trying to make it more streamlined, where it’s as protective, but softer and safer,’’ Shanahan said.

Goaltending styles evolve over time. Some of this evolution is based on the success of goalies who have a certain style that gives them success and then other goalies play the copycat game.
Patrick Roy had great success with the butterfly style and most of the goalies coming out of Quebec emulated his style. The emergence of the butterfly goalie is not just about copying a Hall of Famer like Roy, but related to a host of issues that created the drop-and-block style.
In the late 1980’s, goaltending equipment was revolutionized. Heavy and bulky pads stuffed with deer hair were replaced with light foam pads. Pads went from 12 pounds a pair to four and that is significant.
This allowed goalies to be more mobile and lengthened many careers. Goalies could remain mobile as they approached their mid 30’s, allowing them to make east-west type saves.
Bigger goalies obviously cover more net. But with the heavy pads of the 80’s, they had trouble with movement. Welcome the newer lighter pads and big goalies could become quick and big.
Size and quickness is a great combination and it is now the trend in the NHL to have big goalies who cover a ton of net and can move east to west.

More details are coming in about the new stick being developed by TaylorMade and hockey equipment manufacturer CCM. Already in use by a couple of NHL players, the RBZ stick will be introduced in June at the NHL Entry Draft and should be available at retail this fall. Unlike the company’s new line of metalwoods and irons, the RBZ does not stand for “RocketBallz,” but rather “RocketBladez.”
According to TaylorMade chief technology officer Benoit Vincent, the stick uses a fundamentally different structure than typical hockey sticks.
“The blade on a hockey stick, which is analogous to the club head on a golf club, is responsible for making contact with the puck and imparting the energy stored in the shaft during a player’s swing,” Vincent wrote in an email to Golf Digest this morning. “By understanding how a metalwood club face is designed to maximize COR [coefficient of restitution, or spring-like effect, the rule limiting the speed-producing potential of a clubface], we drew upon this concept to develop the very first completely hollow, or air-core, structure in a blade.
“Traditionally, hockey stick blades have been a sandwich structure comprised of composite skins adhered to an inner core made of polymer foam. By removing the foam through a novel structural design and manufacturing process, we have not only improved the mass distribution in the stick for a faster swing speed, but the unsupported region on the blade face increases COR. We combine these blade improvements with a shaft that has a finely tuned stiffness profile to return maximum energy at puck release.”

Kris King, the NHL’s senior vice-president of hockey operations, said even though the league and the NHL Players’ Association mandated soft-cap elbow and shoulder pads, with at least half an inch of padding over any hard plastic caps, over the last several years, and reduced the size of the shoulder pads, efforts are continuing to make the shoulder pads smaller yet. The NHL made soft-elbow pads mandatory in 2003 and did the same with shoulder pads for the 2010-11 season. The CHL introduced them this season as part of a strategy to reduce concussions.
King said the NHL’s statistics show the number of concussions from blows by elbows to the head is “enormously reduced” since 2003. However, he said the statistics for those hits plus shoulder hits to the head that result in concussions will not be made public until the NHL’s annual general managers meetings in March.

Compared with state-of the-art composite materials favored by the other players on the ice, the age-old wooden material dampens the sting of vibrations more effectively, making it simply more comfortable for goalies to wield a wooden stick.
In Flint, Mich., Kettering University undergraduate student Linda Hunt studied the way goalie sticks respond to impacts along with her adviser, Daniel Russell. Presented earlier this month at the meeting of the Acoustical Society of America in San Diego, the project quantified a feeling often expressed by many goalies playing at higher levels….
Most NHL goalies use wooden sticks, officials from the Carolina Hurricanes and Columbus Blue Jackets said. Hurricanes equipment manager Bob Gorman explained that one of their goalies does use a composite stick, primarily because it weighs less than a wooden one.
The energy of a frozen puck traveling 100 mph is quickly absorbed by the thick padding of a goalie’s leg pads. But the sticks—wooden or composite—are not as forgiving. The puck transfers its energy to the stick, which vibrates violently.
[Please welcome high school hockey coach Dennis Boomer, who kindly tested the Easton Stealth RS and provided his thoughts on the stick for Kukla’s Korner readers.]
As soon as I picked up the stick I noticed how light it was. I prefer a heavy stick, but as I used the Easton Stealth RS, the light weight didn’t bother me as much. Also the shaft has a tacky finish to allow for a better grip, which helps in stick handling and doesn’t interfere with play like other tackified sticks.
But shooting the puck is where the Easton Stealth RS separates itself from other sticks. The wrist shots and snapshots are greatly improved because of the tapering of the shaft. The puck really jumps off the stick blade with far less effort than some of the older sticks.

Most helmets are designed to do one thing well: Prevent catastrophic head injuries.
And they do.
As for stopping concussions, that’s more of a work in progress.
Hoshizaki said that helmets are constructed to shield players from linear impacts, such as when a player falls backward and smacks his head on the ice.
But his research has shown that most concussions occur through what’s called angular acceleration, where a player suddenly turns into a big hit. That’s what happened to Crosby, who took an abrupt shoulder to the side of the head against Washington on New Year’s Day.
In his next game, Crosby was checked into the boards (more of a linear impact but his brain may have been still recovering, Hoshizaki said).
“Can the helmet do better? Yes,” said Hoshizaki, whose lab tests around 5,000 impacts a year involving football and hockey helmets, along with those used in Alpine skiing. “But they will never prevent concussions, just help decrease the risk of concussions.”
