Overuse injuries in youth sports have become common

Youth sports have evolved over recent decades. Among the most obvious changes are the higher levels of competition. It is not uncommon for an athlete to compete for several different teams during the same season. This uncontrolled exposure to injury often results in overuse orthopedic injuries in children.

Overuse injuries are the result of chronic repetitive trauma to a joint. As opposed to an acute injury, the symptoms are subtle and gradually worsen, making diagnosis of these injuries more challenging.

Typically, these injuries affect the bones, muscles and tendons in a joint. They include sprains, strains and stress fractures. Treatment includes rest, ice and anti-inflammatory medications.

A recent study presented at the American Orthopedic Society for Sports Medicine looked at 149 Japanese pitchers ages 7-11. None of the athletes entered in the study had elbow pain at the beginning of the season. Those who threw more than 50 pitches a day and 200 pitches per week while playing in more than 70 games per year were more likely to develop elbow pain.

Some American little leagues do not allow an athlete to throw more than 50 pitches per game. Another solution to overuse is to play multiple sports that use different skills and biomechanics.

“Pain is the principal sign that it’s time to take a break,” reports Dr. Ashok Kotaratharra, a local pediatrician at UCFS. “Trying to hang in despite discomfort may lead to permanent injury.”

Parents should carefully monitor workout schedules and be sure that young athletes receive proper coaching to avoid overuse injuries that can shorten a potentially stellar sports career.

Be careful when exercising in the hot weather this summer

Athletes accustomed to performing their regular outdoor training regimens often continue despite drastic changes in climate. During summer months, this persistence can result in severe injury.

The human body strives to maintain an ideal body temperature of 98.6 degrees Fahrenheit. This requires the interaction of temperature receptors in the skin that relay information to the brain.

The hypothalamus is the area of the brain that interprets this information and, in the case of elevated temperatures, signals muscles and sweat glands to begin a cooling process. Any malfunction in the process, or subjecting the body to overwhelming temperatures, can result in heat-related illness.

Heat stroke is the most severe of the heat-related illnesses. It typically occurs when the body temperature rises in excess of 103 degrees.

The body responds by increasing the heart rate to pump more blood to the skin, where it can become cooled. It also pumps more blood to muscles to keep up with metabolic demand.

In an effort to lower the core temperature, blood is diverted from the brain and other essential organs. Symptoms include a racing heart rate, lightheadedness, muscle cramps, headache and confusion. If ignored, these symptoms can lead to a loss of consciousness.

“Here are three tips for exercising in hot weather,” reports Dr. Douglas Casa, Professor of Kinesiology at the University of Connecticut. “1) Take it easy — you can not push as hard as you can in cool conditions, so back off a little; 2) If you ever start to feel something is amiss, listen to your body and lower your intensity and seek cooler conditions; 3) have cold fluids and cooling towels at the ready for you or your children when exercising in the heat.“

Caution when exercising in extreme heat can avoid serious injury.
