Profile

Dr. Martin earned his Ph.D. from the Pennsylvania State University in Kinesiology, with an emphasis in biomechanics and motor control.  He holds an M.S. in Mechanical Engineering and an M.S. in Kinesiology from the Pennsylvania State University.  Prior to graduate school his undergraduate work was in Mechanical Engineering at SUNY Binghamton.  Since 2016 he has served as the program director for the MS in Exercise, Fitness and Health Promotion degree program at George Mason University. His research interests are focused on improving the health of emergency responder populations. Dr. Martin has been the author a number of articles published in peer-reviewed journals and is actively involved with the National Strength and Conditioning Association (NSCA). He is currently serving on the NSCA Virginia advisory board and the executive council of the NSCA special interest group for tactcial strength and conditioning. Outside of work Dr. Martin enjoys training to improve his own health and fitness. 

Research Focus & Projects

My main area of research is focused on improving the fitness and health of tactical athlete populations (firefighters, police and military). These populations have physically stressful occupations and are a relatively higher risk of injury or other health related issues. The focus of my work is to address the injury and health problems. The first aim is to understand current movement abilities and fitness levels of these populations at various points in their careers. The second aim will be to use movement and exercise interventions to improve their overall health. This work is being performed out of the SMART Laboratory on the Science and Technology campus. Additionally, I have interests in the biomechanics and motor control of human movement.

I’m currently working on several projects. The first is an investigation of health and fitness of tactical athletes in Prince William County. This research focus is being conducted with the Prince William County Public Safety Department. The goals are to reduce injuries through implementing improved fitness programs that target causes of injury and promote a higher exercise program adherence rate. Several specific areas of interest are how baseline fitness, health and lifestyle impact: 1) successful completion of academies or basic training; 2) injury rates during these academies; and 3) long term fitness and health as a professional tactical athlete. Additionally, investigating the relationship between various components of fitness and the ability of emergency responders to perform occupational tasks. Firefighters and WPE as an example. 

Examining the biomechanical effects of the utility belt on core musculature in police officers. In the police force about 60% of all officers will experience lower back pain at some point in their career. Anecdotally, many police officers state that wearing a duty belt contributes to low back pain. However, literature investigating these claims is scarce to non-existent. This project is exploring acute changes in muscle activation due to wearing the utility belt.
