Help KSI Prevent Sudden Death in Sport

This Web site is the public face of the Korey Stringer Institute, a labor of love, and legacy for my late husband, Korey Stringer. In 2001 Korey died of complications after an exertional heat stroke that occurred during football practice.


Exertional heat stroke is the most dangerous of several heat-related illnesses, and is only recognizable if you know what to look for.  Many modifications can be made to prevent a case of exertional heat stroke, and if it does ever occur, rapid and proper treatment has yielded a 100% survival rate.  The recent statistics regarding exertional heat stroke are not encouraging since they show that death from exertional heat stroke it is more prevalent than ever.


My goal in founding the Korey Stringer Institute is to ultimately minimize sudden death in sport for any reason, beginning with exertional heat stroke. This can only be accomplished through awareness, education and research into the best ways to prevent, recognize and treat symptoms quickly and accurately; and, it can only happen with the help of the entire sports community, athletes, and athletic and medical advisors who can set policies, require education and create emergency action plans for and within their communities and organizations. 


I would like Korey’s legacy to be about life and saving lives. I don’t know a better way than to offer sports-related professionals and lay-people alike a go-to resource they can use every day for the latest information, tools, and educational opportunities they need to save lives.


Dedicated with hope and love,
Kelci Stringer

Korey Stringer's Story

In August 2001 Korey Stringer, a Minnesota Vikings offensive lineman, died from Exertional Heat Stroke. Korey Stringer played for the Minnesota Vikings and during his five-year tenure earned pro-bowl honors. Since the time of Korey’s death, Korey’s wife, Kelci Stringer, has worked tirelessly to develop a heat stroke prevention institute to honor her husband’s legacy. To that end, she has joined forces with Exertional Heat Stroke expert Douglas Casa, Ph.D, ATC from the Neag School of Education at the University of Connecticut, Department of Kinesiology to make this dream a reality.

What is Exertional Heat Stroke?

Exertional heat stroke death is one of the leading causes of sudden death in sport. During certain times of the year, it is likely the leading cause of death. Many cases of exertional heat stroke could be prevented if strategies to enhance the health and safety of athletes i.e., focus on hydration, phase-in programs for heat acclimatization, access to on-site medical care, etc., were improved. Additionally, when an exertional heat stroke does occur – not all cases could ever be prevented within the confines of athletes performing intense exercise in the heat – proper recognition, treatment and emergency action-plans need to be in place to assure athlete survival.


The crux of the problem is that current polices for decreasing the incidence of exertional heat illness are extremely ineffective, and the potential for inappropriate care continues to be a large threat. The Korey Stringer Institute will strive to help resolve these problems.
