Hydration in the heat for young athletes

Young athletes, parents and coaches frequently ask about safe ways to hydrate in the heat. They want to know how much—and what—to drink to safely perform at their best.

The answers aren’t simple. The scientific research is inconclusive, and experts disagree.

To help sort out the science and provide practical advice, we talked to E. Randy Eichner, M.D., professor emeritus of medicine at the University of Oklahoma Medical Center and former team internist for the Oklahoma Sooners football team. Eichner spent 14 years caring for Sooners football players in dauntingly hot conditions. And for three years he also served as a physician for the Hawaii Ironman, one of the longest, most grueling, and hottest athletic competitions in the U.S.

Sudden Cardiac Arrest: Six Key Facts

Sudden cardiac arrest is the number one cause of sudden death in exercising young athletes.

It usually strikes without warning in individuals with a structural or electrical abnormality of the heart, often inherited. Males, African-Americans and male basketball players appear to be at increased risk.


No method of detecting heart problems in athletes is perfect.

A complete medical history and physical exam are required for all young athletes before they participate in sports. Some medical experts are adding a screening electrocardiogram (EKG) to the standard pre-participation physical exam.

In some cases, warning signs or symptoms can help identify an athlete at risk of a sudden cardiac arrest.

Signs of a potentially risky heart condition include fainting or passing out during exercise; extreme shortness of breath or chest pain with exercise; palpitations (heart racing) for no reason; and unexplained seizures.

Until proven otherwise, you should suspect sudden cardiac arrest in any collapsed and unresponsive athlete.

Unless effective emergency steps are taken immediately, the athlete will die or be left with serious brain damage.

Every team should have—and practice—an emergency action plan for sudden cardiac arrest.

It is critical that your coach review and practice the emergency action plan in the preseason with all of the people who may be involved in the emergency response.

Life-saving measures include calling 9-1-1, immediate chest compressions (cardiopulmonary resuscitation), and shocking the athlete with an AED as soon as possible.

Early initiation of all of these measures is important. Early shock (defibrillation) with an automated external defibrillator (AED) is the most important factor for survival. A few minutes’ delay can be the difference between life and death.

Sudden cardiac arrest: Know the danger

Every two to three days in the U.S., a young athlete dies as the result of sudden cardiac arrest. In fact, sudden cardiac arrest is the number one cause of sudden death in exercising young athletes.

In most cases, the arrest occurs with no warning. In the midst of play or practice, the athlete suddenly collapses. And if appropriate action is not taken within minutes, the athlete will die or be left with serious brain damage.

This information is for you if you want to learn about the causes of sudden cardiac arrest and the athletes who are at greatest risk. Being aware of the danger is the first step in preparing to save a teammate’s life.
