| Outline of Final Research Achievements |
The purpose of this study was to determine whether or not microcurrent electrical neuromuscular stimulation (MENS) after high-intensity exercise (including eccentric contractions (ECC) ) promotes recovery from muscle fatigue in human muscle. We examined whether or not MENS treatment promotes recovery from muscle tensile weakness that occurs after two high-intensity exercise tasks: single-joint maximal volantary ECC exercise and high-intensity exercise with practical training. The results showed that the MENS treatment accelerated the recovery of muscle tensile weakness and delayed onset muscle soreness in the MENS group compared to the placebo group. The results of this study suggested that the MENS treatment can be used as a means of recovery from muscle dysfunction after high-intensity exercise, despite the lack of evidence for such recovery methods.

MENSの通電機器は，携帯可能なもの，値段が安価なもの，使用に特別な資格が不要なものも多い．そのため，時間，場所，人を選ばすに通電可能であるという，高い実用性と汎用性を有する．
MENSの通電により，筋機能，DOMSの回復促進が示されたことは，アスリートに対しては，素早い筋機能回復と傷害予防のために活用できる．一般の人については，ECCトレーニングは筋力増強のみならず，様々な疾病予防効果を有するため，運動後のMENSの実施は，DOMSや筋疲労を軽減させ，トレーニングの習慣化に貢献しうる．このように，多くの運動愛好家に対して生活の質を高め，医療経済面においても有用となるMENSの活用が可能となる．
