Cool, air blown under football shoulder pads reduces body temperature and heart rate, research finds
Date:7/9/2008

ORLANDO, Florida Cool, dry air flowing between the athlete and their football pads reduces core body temperature and heart rate dramatically, thereby reducing the likelihood of heat-related illness, a study released today at the 2008 American Orthopaedic Society for Sports Medicine Annual Meeting at JW Marriott Orlando Grande Lakes shows. The study found that air forced under the uniform, rather than misted, cool air blown on to the uniform, could be a helpful measure to avoid heat-related illness in football players. This study, funded by a grant from NFL Charities, represents a novel advancement in the pursuit of methods to decrease the incidence of heat related illness.

"Heat stroke in football players has unfortunately been brought to national attention following the deaths of five football players between 2001 and 2004," said lead author Mary Beth Horodyski, EdD, Associate Professor and Director of Research for the Department of Orthopedics and Rehabilitation at the College of Medicine at the University of Florida. "We wanted to look at this new technology for cooling the athlete by blowing cool, dry air underneath their uniform to see how it would affect body temperature and heart rate."

Heat-related illness happens when the systems used by the body to regulate heat become overwhelmed and cannot compensate. Under these conditions, heat and body temperature climbs uncontrollably. Since 1995, 31 football players have died from heat stroke (23 high school, 5 college, and 2 professional, and one sandlot*).

This study monitored 15 athletes wearing shoulder pads, shorts and football helmets who participated in two testing sessions: on one day no air was blown under their shoulder pads and on another day cool, dry air was blown under the shoulder pads during rest periods and the recovery session. Three, 15-minute exercise cycles, separated by 10-minute rest periods were followed by a 20-minute recovery session. The exercise cycles consisted of jogging and sprinting on a treadmill in a room with a heat index of approximately 92 degrees Fahrenheit.

The study found that on the testing session day when the athletes had the cool, dry air blown under their shoulder pads, there was as much as 1 degree Fahrenheit reduction in core body temperature. The most dramatic difference in core body temperature was during the third recovery period. The athletes' average core body temperature was 100.3 degrees Fahrenheit for the cool dry air testing sessions, but for the same time period the average core body temperature was 101.7 degrees Fahrenheit without the cool dry air.

Additionally, with the cool, dry air the athletes had a significantly lower heart rate of about 8 to 10 beats per minute than without the cool, dry air.

"Obviously when the air was blown underneath the uniforms, the athletes benefited," said Dr. Horodyski. "Any small amount of reduction in core body temperature and decrease in heart rate could be the difference between an athlete suffering a heat-related illness or not. We need to continue investigating new technology such as this to prevent heat illness."
