How Roller Coasters Effect The Human Body Introduction: My presentation will show how riding roller coasters can affect the human body in following areas: The Heart The Neck & Back The Mind
The GG-Force Effect On The Heart Definition: force is the force created when a high speed object changes direction. The change of direction usually follows a curved path. On a roller coaster G-forces constantly push and pull at our bodies. If we go fast enough, the force of gravity can stop the flow of blood to our brains and eyes, causing blackouts or temporary blindness. The American Heart Association says riding a roller coaster can speed up the heart-rate in many individuals. Researchers believe that the increased heart-rate is a result of psychological stress, triggered by fear of the roller-coaster, as well as the G- forces acting on the riders. For most people, especially young people, an increased of the heart-rate is not a problem. An increased heart rate can lead to an irregular heartbeat. This can be dangerous for those who, may or may not know that they have heart problems which can cause them to have a heart attack if they ride a roller coaster.
Whiplash Injuries Because roller coaster rides can make quick, and sudden movements, it can cause spinal injuries known as whiplash in some people. Typically, the effects of whiplash dont show until maybe a day or two after the person leaves the ride. Whiplash injuries can cause pain in the neck or back, as well as reduced movement in the arms.
Psychological Effect For some people the very idea of getting on a roller coaster can be very frightening . They don’t know whether to go on the ride or not. Even before the ride, this psychological reaction has a physical side-effect, causing people to sweat more than usual. Your heart starts to beat faster, your bladder starts to take control, and you have a feeling something bad might happen.
So why do we do it? In spite of all the craziness, we ride the roller coasters anyway because we like it and its FUUUUNNNN!!!! (-:
