Survey Reveals Misconceptions About Beverages And Hydration

According to a recent survey, almost 80 percent of U.S. adults believe they need to drink eight glasses of water each day to stay hydrated while 72 percent do not believe they get adequate amounts of water from their daily diets and typical drinking habits.

Blowing Cool, Dry Air Through Football Shoulder Pads Reduces Heat Illness Risk

Blowing cool, dry air flowing under and through football shoulder pads reduces core
body temperature and heart rate dramatically, thereby reducing the likelihood of heat illness,
says a 2008 study.

Football Players At Greater Risk of Heat Illness

While deaths of football players from heat stroke are down (with only one during 2012-2013, compared to 5 in 2011 alone), eat stroke is an ever present concern in the sport because, according to an 2008 study by researchers at University of Florida, there are eight factors that make football players especially vulnerable to heat illness.

Dehydration At Summer Sports Camps Common, Studies Say

If your child is heading off to sports camp this summer, experts say that the chances are he or she will be dehydrated at camp.  According to studies at the University of Connecticut, between 50 and 75 percent of boys and girls attending summer sports camps are significantly dehydrated, with 25 to 30 percent of the campers studied showed signs of serious dehydration, putting them at increased risk of heat-related illnesses.

Too Hot to Play Sports? Depends on Heat Index

When the heat index is above 95 degrees, athletes, especially children, are at increased risk of heat-related illness. Cancelling or modifying practices and games, or taking others to reduce the risk of heat illness, should be taken.

Dehydration: Signs and Symptoms

Dehydration can begin when an athlete loses as little as 1 percent of body weight. In a 70-pound child, that is less than 1 pound of weight lost through sweat. As little as a 2% decrease in body weight from fluid loss (e.g. 1.2 lb for a 60-lb athlete, 2.4 pounds for a 120-pound athlete) can lead to a significant decrease in muscular strength and stamina.

 

 

 

 

Heat Illnesses: Basic Information

Athletes who exercise in hot or humid weather are prone to three different types of heat illnesses: heat cramps, heat exhaustion or heat stroke.

Reducing Heat Illness Risk in Youth Football

Youth football coaches should adopt practice modifications and employ a strategy to acclimatize players to perform in the heat, along with a fluid replacement strategy in anticipation of young players who begin practice already dehydrated, according to new recommendations from the American College of Sports Medicine (ACSM), the world leader in the scientific and medical aspects of sports and exercise. The guidelines are outcomes from a recent expert panel convened for an ACSM scientific roundtable on youth football and heat stress.

Modify or Cancel Games or Practices In High Heat or Humidity

Extremely hot or humid weather may require that sports practices or games be modified or even cancelled because of the risk of heat illness. In deciding whether to do so, you should keep in mind that hot, dry weather can be extremely dangerous. Because sweat evaporates very quickly in such conditions, your child won't feel sweaty, and neither you nor your child may recognize how much water he or she has lost. As the relative humidity increases, the effectiveness of sweating in cooling the body also decreases. When the relative humidity is high, sweat drips off the skin so that the cooling benefit of evaporation is lost even at cooler temperatures, resulting in a build-up of body heat.

Ten Ways to Prevent Heat Stroke in Student-Athletes

Among the steps for preventing heat stroke among student-athletes are acclimatizing athletes to the heat, limiting or cancelling practices in hot, humid weather, and recognizing the warning signs of heat illness.
