Research Abstract

In order to develop vertical jumping ability, a new training method was conceived by the investigators of this project. I has been believed that the best way to develop vertical jumping ability is to strengthen one's leg muscles through resistance training such as squatting, leg extensions, bouncing, plyometrics, etc.. On the other hand, it was reported that free jumping was more effective training than resistance training for developing jumping ability. The new method conceived by the investigators is called suspension training. In the training, a subject is pulled upward by a rubber tubing which is attached to subject's hip-belt to reduce the weight load on the legs. Experiments utilizing male and female athletes as subjects statistically proved that this new training method is more effective than free jumping when trained under the condition of 10% body-weight reduction, 10 repetitions of jumping a day, 3 days a week and 8 week period. On the contrary, it was found that suspension t … More raining was not significantly superior to free jumping for non-athlete subjects. It also clarified that no significant differences were observed between suspension and free jumping trainings when jumping forms of subjects were regulated. Biomechanical analysis using foot pressure monitoring devices, goniometer, video motion analyzer reviled that the suspension training did not develop the leg muscle power out-put but also extended the kicking-time on the acceleration curve and increased the kicking-distance on the displacement curve of the center of gravities of the subjects. It was concluded that suspension training was superb training method for athletes for developing vertical jumping ability however application of the training to non-athletes was no more useful than free jumping. Three types of apparatuses were designed and constructed, one for the training in gymnasium which could be used by 6 people at one time, one for the training in out-door for athletes of various sports, and one for the training for high-jumper.
