Muscle Cramps in Teens: Causes and Care Tips - Neurology

Cramping in the thigh and calf muscles?


My daughter is 14 years old.
Two days ago, she participated in a relay training session and experienced mild cramping three hours later.
The next day, during the official competition, after warming up and attempting to run, she suffered severe cramps in her thighs, calves, and sides of her abdomen, making it impossible for her to move.
After canceling the competition, her legs became stiff, and any slight movement or bending resulted in further cramping.
This condition has persisted for 36 hours.
What could be the cause, and how should she be cared for? Is there a need for medical attention?

To: Katherine
A 14-year-old girl experiencing muscle cramps after exercise training may be due to muscle fatigue.
Other factors, such as low calcium levels, can also cause similar symptoms.
If there is no improvement after resting, it is advisable to seek medical attention.

More Info


Muscle cramps, particularly in teenagers, can be a common occurrence, especially during physical activities such as relay training or competitive sports. Your daughter's experience of experiencing cramps in her thighs, calves, and abdominal sides after an intense training session is not unusual. Let's explore the potential causes of these cramps, care tips, and when it might be necessary to seek medical attention.


Causes of Muscle Cramps in Teens
1. Dehydration: One of the most common causes of muscle cramps is dehydration. During intense physical activity, especially in warm weather, the body loses fluids and electrolytes through sweat. If these are not adequately replaced, it can lead to muscle cramps.

2. Electrolyte Imbalance: Along with fluids, electrolytes such as sodium, potassium, calcium, and magnesium are lost through sweat. An imbalance in these minerals can contribute to muscle cramps.

3. Overexertion: Engaging in prolonged or intense physical activity, especially if the body is not accustomed to it, can lead to muscle fatigue and cramps. This is particularly relevant in your daughter's case, as she participated in a three-hour training session followed by a competitive event.

4. Poor Conditioning: If a teen is not adequately conditioned for the level of physical activity they are participating in, they may be more prone to cramps. This can be exacerbated by inadequate warm-up or cool-down routines.

5. Inadequate Warm-Up: Failing to properly warm up before engaging in strenuous activities can increase the risk of muscle cramps. Warm-ups help prepare the muscles for exertion and can prevent injuries.


Care Tips for Muscle Cramps
1. Hydration: Ensure your daughter is well-hydrated before, during, and after physical activity. Encourage her to drink water or electrolyte-replenishing drinks, especially if she has been sweating heavily.

2. Stretching: Gentle stretching of the affected muscles can help alleviate cramps. For example, if her calf muscles are cramping, she can try standing on a step with her heels hanging off the edge and gently lowering her heels to stretch the calves.

3. Rest: Allow her to rest the affected muscles. Avoid any strenuous activity until the cramps subside.

4. Heat Therapy: Applying a warm compress or heating pad to the cramped muscles can help relax them. A warm bath may also provide relief.

5. Massage: Gently massaging the affected area can help increase blood flow and relieve tension in the muscles.

6. Nutrition: Ensure she is consuming a balanced diet rich in vitamins and minerals, particularly those that support muscle function, such as potassium (found in bananas), calcium (found in dairy products), and magnesium (found in nuts and leafy greens).


When to Seek Medical Attention
While most muscle cramps can be managed at home, there are certain situations where medical attention is warranted:
- If the cramps persist for more than 24 hours without improvement.

- If your daughter experiences severe pain, swelling, or bruising in the affected areas.

- If she has a history of medical conditions that could complicate her symptoms, such as kidney issues or metabolic disorders.

- If she experiences other concerning symptoms, such as weakness, numbness, or changes in sensation.

In summary, muscle cramps in teens can often be attributed to dehydration, electrolyte imbalances, overexertion, or inadequate warm-up. By ensuring proper hydration, stretching, and rest, you can help alleviate her symptoms. However, if the cramps persist or worsen, it is advisable to consult a healthcare professional for further evaluation and management.
