Porpoising in F1 racers, which are the cars' sometimes-violent undulations, is due to the new aerodynamics of this year's cars. While other teams said [Wolff may be exaggerating](), according to *[Motorsport.com]()*, Wolff cited a study that claims drivers risk brain damage from the constant bouncing. "The FIA has commissioned medical work on the porpoising. The summary of the doctors is that frequency of 1-2 Hz, sustained over a few minutes, can lead to brain damage. We have 6-7 Hz over several hours." Wolff said. While Wolff claims he was shown that study during a meeting, and doesn't cite the study itself, there could be some truth to his claims. According to the [Journal of Stroke and Cerebrovascular Diseases](), there may be a link between constant vibration and brain injury. In a[ 2015](), motor vehicle-induced whole-body vibration can cause significant brain injury, mostly by causing cerebral vasoconstriction, which limits blood flow and oxygen to the brain. The study was done on nine groups of rats, to see if vibrations from motor vehicles could cause long-term brain injury. Four of those groups were subject to whole-body vibrations of 30Hz and 0.5G acceleration for four hours per day, five days per week, for several weeks. Afterward, all rats were subject to behavioral, physiological, and histological brain studies. ![]() *Mercedes' Lewis Hamilton during the Hungarian GP | (Photo by Arthur Thill ATPImages/Getty Images)* All of the rats in the study, including both the vibrated rats (a phrase I never thought I'd type) and the non-vibrated rats in the control groups were physically fine. However, the vibrated rats all showed a decline in cognitive ability compared to the control rats. Maze tests proved the vibrated rats were consistently more hesitant to make decisions and were often more confused. They also suffered weakened grip strength, a slower reaction to heat, and a slower reaction to pain. Although Wolff may have been talking about another study, a possible link between vibration and cognitive ability is there. The issue has gotten better over the past few weeks, with fewer drivers mentioning porpoising issues. However, Wolff says that point is moot. “The argument is we haven't had any porpoising and bouncing in the last few races. But it doesn't count because Silverstone, Paul Ricard, and Austria aren't exactly tracks that we bounce at anyway.” he said. Other teams, such as [Red Bull ]()and [Ferrari](), have learned how to overcome the bouncing issue and claim it isn't a safety issue but an engineering one. But Wolff and the FIA seem to think that a change needs to be made next season. ## Author Nico is a writer and reviewer from New Jersey who probably thinks he’s a lot funnier than he actually is. His love of cars began when he was just a kid playing Gran Turismo 3, grinding out enough race wins with a Mazda Miata to save up for an in-game RUF 911. That passion for small, lightweight sports cars drove his desire to learn more about the industry, get his hands on as many cars as he could, and bring those experiences to life on the page. He cut his teeth writing about BMWs, Volkswagens, and Audis, mostly, and has owned far too many of each. He’s on his fourth 3 Series sedan, but all of his old, cheap German cars have forced him to learn more about car maintenance than his mechanical capability can handle. Too many late nights have been spent scrambling to get a car running by morning so he could get to work. For some reason, he never seems to learn that old Bimmers probably aren’t the best daily drivers. But he loves more than just old German cars. He’ll gladly drive and discuss anything with four (or even three) wheels. Cars aren’t his only passions, though. Nico is also a big nerd and loves movies, video games, comic books, and cares far too much about the New York Giants. So don’t be surprised if you see football references or dumb, obscure movie quotes in any of his car reviews. ### Author social links [Instagram]() [LinkedIn]()
