In general, the sport is viewed as similar to tennis and handball because many of such games rules are incorporated into racquetball. However, the truth is that this sport is unique. How did it originate? Joe Sobek, a US-based professional handball and tennis player, is credited for inventing the game in 1950. The IRF or International Racquetball Federation facilitates the entirety of the World Racquetball Championships which initially took place in 1981 along with the very first World Games. Three years later players across the world again took the grand stage and since then the event has been done biennially specifically in August. A served ball that strikes the front wall and on the rebound reaches the server so close that the receiver is unable to have a clear view is called a screen serve. There are also various forms of hinder in the game. Play is halted when the ball makes an abnormal bounce off a rough or irregular surface or when it makes contact with any portion of the court that was pre-determined as a court hinder. The principle of warming up is based on increasing the flow of blood across the muscles so as to promote readiness and strengthen their capacity in withstanding the workload during a game. Stretching and jogging are the common methods used. You only need to allot 10 to 15 minutes. At this point you can let your body have a feel of what the court condition is like. The ball will bounce to the floor nearly behind the center court heading to the other back corner. From there, it will make a second bounce after hitting the back corner wall. Other defenses There are other defensive moves done usually by the pros of the game. Some are combinations of these popular ones and some are variations. Finger formation Without the right knowledge on the proper and consistent grip of your racquet, you will remain clueless to the real feel of what a racquet is. The end result can be serious control problems in the future. For beginners, this can be a source of great frustration that can drive one away from the game altogether.
