'What we should be concerned about is not G forces, but the effects of rapid head acceleration – the rotational force on the brain that occurs as the body quickly changes directions,' said co-author David F. As the researchers point out, an average person could momentarily experience eight to ten Gs by plopping down onto the couch to watch Top Gun. High G maneuvers on roller coasters, however, rarely last more than three seconds. But these effects are from sustained Gs over an average of 43 seconds. The biggest risk of high Gs is a loss of consciousness as blood pools in the limbs and away from the brain. Just as unsuspecting car passengers are forced against the door during sharp turns, pilots feel accelerations as they make quick maneuvers – except for pilots, these accelerations can be as much a five to nine times the force of gravity (or Gs).

Most people are familiar with the dangers of G forces as they affect pilots, as popularized in film and television. In fact, G forces really aren't the issue here.' 'To our knowledge, no peer-reviewed studies have definitively linked brain injury in healthy individuals to riding the latest, and most powerful roller coasters.

Smith, MD, from the Department of Neurosurgery and the Head Injury Center at the Penn School of Medicine and co-author of the study. 'We should step back and separate the facts from the hype,' said Douglas H. Their findings are presented in the October issue of the Journal of Neurotrauma. House of Representatives.Īccording to a pair of researchers at the University of Pennsylvania, however, medical science does not support the notion that roller coasters produce forces large enough to harm the brains of riders. Already the State of New Jersey has enacted legislation limiting G forces, and similar legislation has been proposed by members of the U.S. But do bigger thrills come with added risks of injury? Published medical case studies have proposed a link between roller coaster forces and brain injury. (Philadelphia, PA) – To meet the growing expectations of thrill-seekers, amusement park rides have been built bigger, faster, and more exciting.
