The 30-second answer
Bone rebuilds on the same thing that protects it: enough total food, every day, including the weeks the athlete is not running. A stress fracture is bone that was loaded faster than it could repair, and healing is an energy-expensive job that slows down when a rested athlete eats less because they feel they have not earned it. Keep three meals and snacks, keep a protein food at each meal, and put a calcium-rich food into most meals. Vitamin D matters for bone, but whether this athlete needs a test or a supplement is a question for the clinician, not a dose from a coach or a handout. The doctor, the athletic trainer, and the physical therapist decide when and how running returns.
What to do next
- 1
Keep the eating schedule the athlete used while training: breakfast, lunch, a snack, and dinner, and do not cut portions because the athlete is cross-training, in a boot, or resting.
- 2
Add a calcium-rich food to most meals in household units: a glass of milk or fortified soy milk, a cup of yogurt, cheese, calcium-set tofu, canned salmon or sardines with bones, or fortified cereal and orange juice.
- 3
Write the questions for the appointment before you go, and bring the recent training changes and a plain description of a typical eating day so the clinician can see the load and the fuel together.
- 4
Ask the school athletic trainer to hold the return-to-running timeline from the treating clinician so practice does not restart on the athlete’s own guess.
A healing day in household units
- Breakfast: oatmeal made with milk, a spoon of peanut butter, fruit, and a glass of fortified orange juice; or eggs, toast, and a cup of yogurt.
- Lunch and snacks: a sandwich with cheese or meat and a carton of milk; cottage cheese and fruit; hummus with pita; trail mix and a string cheese; leftovers in an insulated container.
- Dinner: rice or pasta with beans, chicken, tofu, or salmon, a cooked green such as broccoli or kale, and milk or a calcium-fortified alternative to drink.
- The questions for the clinician, written out: could how much the athlete has been eating, growth, or menstrual changes be part of this; should vitamin D or other labs be checked; what activity is allowed now; and what has to be true before running again.
What a coach can say
“Your job right now is to heal, and healing takes fuel, so nothing about how much you eat should shrink because you are not running. I am not going to guess why this happened or tell you what to take; those are questions for your doctor, and I want your parent or guardian to ask them. When your care team says you can run, we will build back slowly and I will follow their timeline, not the race calendar.”
What to avoid
- Do not tell the athlete to eat less while injured, and do not frame time off as a chance to get lighter for the comeback.
- Do not hand the family a vitamin D or calcium amount, a supplement brand, or a lab result to aim for; the clinician decides what to check and what to prescribe.
- Do not return the athlete to impact running because the pain is gone; the treating clinician and athletic trainer clear the return.
When general guidance stops
A stress fracture in a growing runner is a reason to look at the whole picture: how much the athlete has been eating relative to training, growth, menstrual changes, a previous bone injury, and any restriction around food. The pediatrician or sports-medicine clinician decides what to check and what to prescribe, a sports RDN builds the individual eating plan, and an eating-disorder-informed clinician joins when food rules or body distress are part of the story. A second bone injury, or one that is not healing on schedule, goes back to the clinician rather than into a longer rest.
Urgent boundary
Sudden severe bone pain, a limb the athlete cannot bear weight on, a visible deformity, numbness, or a suspected complete fracture during practice or a race needs the school emergency action plan and urgent medical care, not ice and a ride home. Fainting, chest pain, or confusion at any point is an emergency route now.
