Outline of Final Research Achievements

I first measured the muscle strengths of lower extremity and trunk among elite soft tennis players, and then examined the relation between shot control ability and such muscle strengths. However no correlations could not be found. Further I tried to analyze 3D motion by using high speed cameras during the consecutive forehand and backhand series, especially trunk and head motion and their frequency analyses. However owing to bad health and serious injury due to the accident. I had to take a leave of absence from my job. Thus I could not gain any results.
