摘要：

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-mm 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. (c) 2012 Elsevier Inc. All rights reserved.
