Trusted head injury prevention technique debunked

10.01.2006


Contrary to popular thinking in athletics, traditional neck muscle resistance training may not protect athletes from head injuries.

For eight weeks, kinesiologists at Temple University worked with male and female Division I intercollegiate soccer players to see if a resistance training program would reduce the player’s head acceleration during impact. According to Ryan Tierney PhD, director of Temple’s Graduate Athletic Training Program, head impacts experienced during soccer cause head acceleration, similar to what a person experiences during a car crash. These impacts may cause mental impairment or accumulate and lead to permanent disability.

His findings are published in the current issue of the Journal of Athletic Training and will be highlighted at the Eastern Athletic Trainers’ Association’s Annual Meeting in Philadelphia, Pa, January 7-10.


"We did see a change in the player’s neck muscle strength but these changes made absolutely no difference in their ability to stabilize their heads when force was applied," said Tierney.

Every year, 1.4 million Americans suffer from a traumatic brain injury caused by a blow or jolt to the head. Moreover, previous research conducted by Tierney found that women are more susceptible to these types of injuries than men. Before Tierney’s latest findings, many scholars and trainers believed that resistance training could reduce these instances among drivers, firearm users and those who participate in sports.

Though traditional resistance training failed with this group, Tierney does not rule out the possibility that other types of training such as plyometrics (higher intensity exercises used to develop power that involve explosive muscular contractions) could be used to combat this problem.

Im Focus: Data use draining your battery? Tiny device to speed up memory while also saving power

The more objects we make "smart," from watches to entire buildings, the greater the need for these devices to store and retrieve massive amounts of data quickly without consuming too much power.

Millions of new memory cells could be part of a computer chip and provide that speed and energy savings, thanks to the discovery of a previously unobserved...

Im Focus: Lethal combination: Drug cocktail turns off the juice to cancer cells

A widely used diabetes medication combined with an antihypertensive drug specifically inhibits tumor growth – this was discovered by researchers from the University of Basel’s Biozentrum two years ago. In a follow-up study, recently published in “Cell Reports”, the scientists report that this drug cocktail induces cancer cell death by switching off their energy supply.

The widely used anti-diabetes drug metformin not only reduces blood sugar but also has an anti-cancer effect. However, the metformin dose commonly used in the...

Im Focus: New Foldable Drone Flies through Narrow Holes in Rescue Missions

A research team from the University of Zurich has developed a new drone that can retract its propeller arms in flight and make itself small to fit through narrow gaps and holes. This is particularly useful when searching for victims of natural disasters.

Inspecting a damaged building after an earthquake or during a fire is exactly the kind of job that human rescuers would like drones to do for them. A flying...
