The present study was carried out to examine the histochemical adaptations of the skeletal muscle fibers induced by standing high jump training. Twenty one Wistar-strain male albino rats were used, of which ten were used for the jump training group and the remainings were as controls (non exercised group). After training for eight weeks, animals were sacrificed, and their soleus and plantaris muscles were excised. Transverse sections from the midportion of the muscle were stained for alpha glycerophosphate dehydrogenase, and those serial sections were prepared for the examination with a light microscope. As the results, there were no significant differences between the jump trained and the control rats as compared with following parameters, changes in muscle weight per body weight, rate of various types of muscle fiber number and comparison of muscle fiber diameter. In the view of the fact that the jump training did not cause the significant hypertrophy of muscle fibers, it suggest that more long term training program and higher intensity of load are necessary to clarify the training effect in tissue level.
