| Research Abstract |
Longitudinal relaxation time (T_1) determined by 3.0-T magnetic resonance imaging of the tibialis anterior and extensor digitorum longus muscles increased gradually with muscle fatigue caused by three 120-s periods of repeated ankle dorsiflexion separated by 5洋in rest periods. T_1 values decreased in the recovery period, although they remained higher than the preexercise values. T_1 values for the soleus muscle were unchanged throughout the experiment. Results suggest that muscle T_1 values increase with increasing muscle fatigue.
