Heat Safety

The loss of electrolytes such as sodium and potassium through sweat can lead to muscle cramps, nausea, vomiting and even death.  Electrolytes are minerals (sodium, potassium, calcium, magnesium, and chloride) which send messages to nerves and muscles throughout the body,  and are involved with muscle contraction and relaxation during exercise, so that an imbalance can impact the actual contraction of the muscle itself.

During pre-season, staying hydrated is one of an athlete's top priorities. Accurate hydration regulates body temperature, fluid, and electrolyte balance, and is essential for comfort, optimal performance, and safety. Hot humid weather, padding and uniforms, along with two-a-days can increase sweat and electrolyte losses tenfold.

Dr. Lindsay Baker, a senior scientist at the Gatorade Sports Science Institute, answers frequently asked questions about sports drinks and  why it is important for young athletes to stay hydrated and consume carbohydrates to perform at their best.

Does your child know his sweat rate?  Turns out it is the key to replacing fluids lost during exercise, according to several studies presented 2010 annual meeting of the American College of Sports Medicine in Baltimore, with experts recommending that athletes replace 150% of the weight loss from sweating in the first four hours after sports.

With summer temperatures soaring, the National Athletic Trainers' Association (NATA) has prepared a list of important tips that people of all ages can follow to enjoy physical activity and exercise and also reduce the risk of exertional heat illness that may occur from activity in the heat of summer. This is especially timely in July and August when young athletes are participating in summer and pre-season sports programs and back-to-school games are just around the corner.

After birth every baby is tested for a wide variety of conditions and diseases. One of the tests looks for the condition called "Sickle Cell Trait."  Ordinarily, a relatively benign condition, sickle cell trait can have potentially devastating implications for youth  engaged in sustained, intense exercise, such as in sports practices, which can result in a life-threatening condition called exertional sickling.

MomsTeam hydration expert, Dr. Susan Yeargin, debunks five common heat illness and hydration myths about children exercising in the heat.

Hyponatremia occurs where sodium levels in the blood become dangerously low due to excessive water consumption.  Blood sodium levels that drop too low can lead to seizures, coma, and even death.  To prevent hyponatremia usually occurs in endurance and ultra-endurance events follow these guidelines.

A child's sports hydration status can be affected, positively or negatively, by beverage type, flavor, container type, accessibility, and parental and coach attitudes about hydration.
