Geisinger becomes the first member of Risant Health

Knoebels has rides that’ll make your heart pound.

By Paula Franken

Ever scrambled to catch a line drive — or screamed for joy in your living room when your team made a game-winning goal? The adrenaline rush that comes with participating in (or watching) athletic activities is nothing new to Geisinger sports medicine specialist Ryan Roza, MD. “Adrenaline stimulates your heart to beat faster, prompts you to breathe more quickly and helps your blood vessels contract. Together, these changes enrich your blood with oxygen and redirect it to major muscle groups. This combination enhances strength! Adrenaline also provides temporary resistance to feeling pain,” he explains. “In a very rapid period of time, all this leads to a burst of better athletic performance.”

Luckily, these physical enhancements apply to your brain as well. A fully oxygenated brain is more focused, and this heightened state of awareness isn’t just efficient — it also feels great. “The feeling lasts long after the excitement is over,” explains Dr. Roza. “It’s something researchers call the ‘excitation transfer theory’ and it can leave your body wanting more.”

Adrenaline that’s released over long periods of time as a reaction to constant stress wears your body down, but short bursts actually boost your immune system, improving your ability to fight off infection, and can even lead to more antioxidants in your system to combat the free radicals that cause aging and tissue damage.

Knoebels, located in Elysburg, Pa., is a family-run business and America’s largest free-admission amusement park. And it’s been a favorite destination for people of all ages for generations.

Safety always comes first.

Always follow the park’s guidelines when it comes to height requirements, sit in designated seats and ride with a responsible party if required. Women who are pregnant and people with underlying health conditions should avoid these more intense experiences. But if you’re in good health and meet the height and age requirements, a thrill ride or two might be just what you need to snap you out of last summer’s COVID rut. Enjoy!
