Yleisurheilupyörätuolit

Yleisurheilupyörätuolit, often translated as athletics wheelchairs or racing wheelchairs, are specialized pieces of equipment designed for athletes with disabilities to compete in track and field events. These wheelchairs are distinct from everyday mobility devices and are engineered for speed, maneuverability, and stability during athletic performance.

The design of an athletics wheelchair typically features a lightweight frame, often made of aluminum or carbon fiber, to maximize speed and minimize the effort required by the athlete. They have a low profile to reduce wind resistance and a reclined seating position for optimal aerodynamics and power transfer. The wheels are a critical component, usually featuring large, spoked wheels with high-pressure tires to reduce rolling resistance. Cambered wheels, where the wheels are angled outward at the top, are common to provide stability during high-speed turns and to allow for more efficient propulsion.

Athletes propel these wheelchairs using their arms, pushing on the handrims attached to the rear wheels. The handrims are designed for grip and efficiency, allowing athletes to generate maximum force. The specific design of the wheelchair can vary depending on the event, with some being more specialized for sprinting, middle-distance, or longer-distance races. They are also adapted for field events such as javelin, discus, and shot put, where stability and a solid base are paramount.

The use of athletics wheelchairs has revolutionized para-athletics, enabling athletes to achieve incredible speeds and compete at elite levels. They are a testament to the integration of engineering and sports science to enhance athletic performance for individuals with physical impairments.
