These shoes had soft leather on the top, had a durable rubber sole, and the collar of the shoe was padded for comfort. PURPOSE: The purpose of this study was to examine the biomechanical differences exhibited by collegiate cheerleaders while performing balance testing and step-down, landing tasks in “old” and “new” cheer shoes. Until now, no detailed biomechanical analysis of back handspring has been reported.

Also the stability of the flyer is affected by the height of the stunt. This begun to be dangerous once they tried to add tumbling skills or stunts to their cheers. The flyer is able to remain more stable within a double base position rather than in an extended position. It can range from chanting slogans to intense physical activity. The flyer is going in a linear motion upwards while being thrown. The final technological advancement would be in uniforms. , 31:881-888, Nov/Dec 2003. For example cheerleading shoes are now made of extremely light material in comparison to the older shoes, they weigh about 0.25 pounds. Isometric Contractions: In this type of muscle contraction the muscle remains in the same length the entire time of the contraction. Attendance at summer camps has grown to more than 500,000 participants annually, and tens of thousands train for regional and national competitions each year, with championships and even college scholarships on the line.

Coaches will … During a kick double basket toss you are using this general motion. Biomechanics Cheerleading is an extremely complex sport and can involve a neverending list of various stunts, jumps, dances, and cheers that incorporate a number of different movements. This study is an attempt to provide biomechanical sup port for the athletic practice of warming up prior to an exercise task to reduce the incidence of injury. This can be demonstrated by front handsprings, back handsprings, backtucks, fronttucks, etc. The flyer is able to remain more stable within a double base position rather than in an extended position. Incorporated within the paper will be a case study describing the mechanism of injury of a professional cheerleader as well as risk management techniques to address injury prevention.
