Masaaki Tsuruike 


Professor Bio

I joined Department of Kinesiology as the Director of Graduate Athletic Training Education Program at SJSU in August 2012.  Before SJSU, I worked as a full professor in Graduate School and the Director of Athletic Training Course in undergraduate at Osaka University of Health and Sport Sciences in Japan for over 15 years, where I started to study physical education for my bachelor degree as well.  I graduated my master’s degree in Kinesiology emphasizing Athletic Training Specialization and PhD in Human Performance with major in Motor Control and minor in Neuroscience both from Indiana University, Bloomington.  At my former university I was involved with American football team as the team director to take responsibility for their official activity while supervising student athletic trainers in the team.  I also had an opportunity to assist Women’s basketball team as an athletic trainer for 5 years.  Meantime, I conducted research activity for the modulation of spinal motoneuron excitability by using conditioned H-reflex techniques to identify differences between elderly and young population during a variety of weight bearing positions.  Currently, I’ve been interested in the muscular activities attached to the scapula for overhead athletes.  Furthermore, I’ve been measuring the scapular muscle activities in the scapulohumeral rhythm with a variety of intensities for SJSU baseball team.  In addition, I’ve been enjoying collaborating with 13 clinical sites for our graduate students working as graduate assistantships in GATEP.  Such clinical sites include a variety of institutes from D1 universities to private high schools all over in Bay area, Santa Cruz, and Monterey as well as SJSU.  Last, I enjoy practicing judo with SJSU Judo Team members and playing tennis with my wife in private.
