Justin Keadle, B.S.

Lab Coordinator
(413) 577-4703

I am the lab coordinator for the Muscle Biology and Imaging Lab. Currently, I am working on the STOMP study (The Effects of Statins on Muscle Performance).  Others studies that I have assisted with include the Metabolic Syndrome study, Muscle Response study, Muscle and Connective Tissue study, Sport study, and Topical Gel study. I received my B.S. in Health and Exercise Science from Wake Forest University, Winston-Salem, NC.  

I am from Huntington Beach, CA where my mother, father, and two brothers currently reside. I am an ex-collegiate athlete who played in the minor league system of the New York Yankees. In addition, I have spent the past two years volunteering as an assistant baseball coach with the University of Massachusetts. My fiancé, Sarah, is currently pursuing her Ph.D. in Kinesiology here at UMass.

Muscle Response Research

Activation of NF-kb in cells outside the myofiber boundary, 3h following eccentric exercise (ECC). A. Confocal images of triple stained 10µm sections from a representative ECC sample for dystrophin (dys=blue), the p-65 subunit of NF-kb (p65=green) and nuclei (topro3=red). White square in merged image denotes the boundaries of the inset image. Scale bar in top 3 images and merged image = 20µm; scale bar in inset image = 10µm. Read the abstract.

Resistance Exercise and Cancer

Dr. Clarkson's research on resistance exercise during breast cancer treatment is featured in Medical Hypothesis, a journal of theoretical papers in the biomedical sciences. Read the abstract.


Rhabdomyolysis is a serious, potentially life-threatening condition that can develop unexpectedly under supervised conditions. Dr. Clarkson's 2009 paper in The Journal of Strength and Conditioning Research examines a case of rhabdomyolysis in a healthy, fit 18-year-old placekicker following a supervised practice session led by the team's strength and conditioning coach. Following eight days of hospitalization with intravenous fluids, the patient recovered without complications. View the full abstract.
