 note = {text, Hypertrophy of the rat soleus muscle was induced by exercise (jump or isometric) training for 5 weeks and myectomy (for 1, 3, and 5 weeks) of the synergistic gastrocnemius and plantaris muscle. Between pCa 7.0 to 4.0 on Ca2+ activated tension development and maximum velocity of shortening were examined in skinned single fibers from the rat soleus muscle. The training and myectomy caused the hypertrophy of muscle fibers, the rate of cross-sectional area(CSA) were 117, 137, 154, 156, 159% in jump, isometric, 1, 3 and 5 weeks postmyectomy groups, respectively. There was a significantly lower in maximum tension per CSA between 1 and 3 weeks postmyectomy groups than the other groups. The lower correlations between the fiber CSA and maximum tension were obtained only 1 and 3 weeks postmyectomy groups compared to the other groups. Thus there were significant differences in slope coefficient of regression equations between the both postmyectomy groups compared to the control, and exercise trained groups. No significant differences between the control group and all hypertrophied groups in respect to the contractile parameters, such as shortening velocities and pCa-tension relations. It was concluded that the time required to achieve a steady-state hypertrophy is established within 5 weeks and that the functional properties of hypertrophied muscle fiber undergoes only minor changes.},
