Purpose of this study is to estimate speeds and directions of water molecules during muscle contraction. Dynamic DTI was performed in order to estimate speeds and directions of water molecules during electrically stimulated contraction. 1 and 2 values showed significant increase during the muscle contraction. These results indicate that rapid water movement occurred in the direction other than muscular long axis at least during the muscle contraction. This study suggests that the muscle contraction induced the movements of the rapid water molecules to muscular short axis direction as well as long axis.
