Sachithra D. Samarawickrame

 
Research Interests
 

My research focuses on identifying the biomechanical and physiological risk factors associated with lower-extremity injuries in athletes. Specifically, I am interested in muscle and tendon adaptation in response to fatigue and eccentric overloading. I am currently using barefoot running as a model to study these adaptations.  My research will ultimately contribute to the development of effective strategies that reduce the prevalence and severity of injuries related to myotendinous injuries related to sports participation
