Abstract

The use of isokinetic dynamometers has recently improved the study of muscle strength. In particular, this study used a specific isokinetic dynamometer to test trunk muscle strength in weight-lifters, boxers, wrestlers and body-builders. Preliminary results emphasise the high levels of extensor muscle strength in comparison to data from a sedentary population. Levels of flexor muscle strength, on the other hand, coincide with those in the sedentary population. Other preliminary results, such as the ratio between trunk flexors and extensors and the different peak torques in the various sports examined in comparison to joint angle, are of considerable interest and require further study. These findings represent an initial stage in the application of the isokinetic method in the study of trunk muscle strength in athletes. Verf.-Referat
