Twenty healthy men volunteered to participate in this study（ age，21.1±0.3years; height，170.5±5.5cm; weight，62.5±5.5kg）. The muscle stiffness， H-reflex amplitude， and M-wave amplitude were measured in the medial gastrocnemius （MG） and lateral gastrocnemius （LG） before and after NMES-induced repetitive muscle contraction condition（NMES condition）or control condition （20min rest）. The ratio of maximal H-reflex（Hmax）to maximal M-wave （Mmax）（Hmax/Mmax） was calculated. During NMES condition， the MG and LG were stimulated using rectangular pulses（ pulse width: 400μs; pulse frequency:80Hz） for 5s（on）with a rest time of 20s（off）between trains. This on-off cycle was repeated until the Mmax decreased to 80% for three consecutive times. The Hmax and Mmax of the MG， Mmax of the LG in the NMES condition， and Mmax of the MG in the control condition significantly decreased; however， there were no significant changes in Hmax/Mmax and muscle stiffness in both conditions. The results of this study revealed that， despite Hmax and Mmax significantly decreasing owing to NMES， muscle stiffness and spinal cord excitability does not change owing to NMES-induced repetitive muscle contraction.","subitem_description_type":"Abstract"}]},"item_19_publisher_35":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"新潟医療福祉学会"}]},"item_19_source_id_11":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AA11614531","subitem_source_identifier_type":"NCID"}]},"item_19_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"1346-8774","subitem_source_identifier_type":"ISSN"}]},"item_19_text_1":{"attribute_name":"Title
