In the high jump event, athletes jump over a horizontal bar using a technique that allows them to clear increasingly higher heights. The world record for the men's high jump is 2.45 meters (8 feet 0.46 inches), set by Javier Sotomayor of Cuba in 1993.

Finally, practicing regularly and receiving feedback from a coach or experienced jumper can help to identify areas for improvement and make necessary adjustments. **
