Muscle Cramps Can Occur at Any Time

As growing athletes participate in sports practice, they may experience issues like muscle cramps as a result of dehydration and improper stretching or warm-ups.

“Muscle cramps are involuntary contractions of the muscles that can occur at any time, interrupting a workout or game in the blink of an eye,” says Lindsey Ream, MEd, LAT, ATC, Athletic Training Manager, Children’s Healthcare of Atlanta Sports Medicine Program.

What causes muscle cramps?

Muscle cramps may be caused by extended periods of exercise, general overuse muscle fatigue, dehydration or muscle strain. And, they can occur anywhere on the body but typically target the lower extremities like calves or feet.

3 tips to prevent muscle cramps

  1. Drink plenty of fluids.
    • Pre-hydrate 30 minutes before an activity. Drink until no longer thirsty, plus another 8 ounces.
    • Drink 5 ounces every 20 minutes of activity for kids and teens weighing less than 90 pounds.
    • Drink 8 ounces every 20 minutes of activity for kids and teens weighing more than 90 pounds.
    For activities that last longer than an hour, a fluid with carbohydrates (sugar) and electrolytes is best. Gatorade and Powerade were designed specifically for rehydration during exercise and contain the right amount of carbohydrates (about 6-8%). We do not recommend drinking fruit juice or soda, as they contain too much sugar for effective hydration and can cause cramping.
  2. Stretch your muscles every day.
    It is important for growing athletes to warm up properly, whether that be a dynamic warm-up or activity specific stretching, ideally before and after an activity. While kids are still growing, stretching before bedtime is also recommended, because they tend to get night cramps.
  3. Don’t suddenly increase activity or the amount of exercise.
    Increase an activity over time and make sure to properly warm up before beginning exercises. Also, an athlete should gradually start an activity they have never tried before or haven’t done in quite some time. We recommend slowly getting back into the activity over a few weeks’ time.

How to treat muscle cramps in teen athletes

If a growing athlete does get a muscle cramp, stretching and massaging the area can help alleviate pain. Most cramps subside within a few seconds, if not a minute. If a muscle cramp gets to be too painful, the athlete can take an over-the-counter medicine, such as Tylenol or Ibuprofen. Be sure to follow the dosage instructions.

If the muscle cramp doesn’t go away and is non-emergent, we recommend following up with your child’s pediatrician. Typically, muscle cramps are not an emergency, but if they persist, it wouldn’t hurt to check with your child’s doctor to make sure there’s not an underlying issue.
