Nutrition for Children and Adolescents Who Practice Sport: A Narrative Review

Open access

Abstract

At a developmental age, adequate physical activity is fundamental to overall health and well-being and preventing obesity. Moreover, establishing active behavior can help children and adolescents meet their growth and neurodevelopmental goals. Nutritional requirements vary according to intensity, frequency, and practiced physical activity or sport; therefore, pediatricians should give children and adolescents and their families adequate counseling, avoiding both nutrient deficiencies and excessive or inadequate supplement intake. The focus should be not only on sports performance but also on the child’s well-being, growth, and neurodevelopment. Our narrative review aims to discuss the nutritional needs of children and adolescents who practice physical activity, non-competitive sports activity, and elite sports activity while also analyzing the role of food supplements and the risk of eating disorders within this category of subjects.

Overview

CoChat Summary

TL;DR

This narrative review discusses nutritional needs of children and adolescents engaged in physical activity, non-competitive sports, and elite sports, including macronutrients, hydration, micronutrients, supplements, and eating disorders. It concludes that age-appropriate nutrition and hydration are usually sufficient for non-elite young athletes, while elite athletes require multidisciplinary support and only selected supplement use under medical/nutritional supervision.

Key findings

  • Energy requirements vary by activity, growth, and development; general estimates for adolescent athletes are approximately 3640 ± 830 kcal/day for males and 3100 ± 720 kcal/day for females, with physical activity contributing about 25–30% of total daily energy expenditure in non-athletic individuals. PAL adjustments of 0.15, 0.3, or 0.6 are suggested for children doing 30 min moderate activity ≥5 days/week, 60 min vigorous sports 5 times/week, or intense aerobic competitive sports, respectively.
  • Carbohydrate recommendations include 50–55% of intake (about 6–10 g/kg) for normal physical activity, at least 50% for high-performance sports, and up to about 70% for exceptionally intense exercise; competition-day timing includes 4 g/kg in the 3–4 h before activity, 0.5–1 g/kg in the hour before, 0.7 g/kg/hour during activity in 15–20 min intervals, and 1–1.5 g/kg post-activity. For elite athletes, endurance exercise of 1–3 h/day requires 6–10 g/kg/day CHO, extreme exercise of 4–5 h/day requires 8–12 g/kg/day, and post-exercise recovery uses 1–1.2 g/kg per hour of training.
  • Protein should contribute 10–15% of daily calories; post-exercise recovery may require about 0.11 g/kg/hour or roughly 1.5 g/kg/day (e.g., about 0.3 g/kg at five mealtimes). Elite adolescent athletes are advised to follow adult protein guidelines of about 1.3–1.8 g/kg/day, and usual intake of 1.2–1.6 g/kg/day is consistent with adult recommendations, so protein supplements are not necessary.
  • Hydration and micronutrients are emphasized: 13 mL/kg per hour of exercise is suggested, water is sufficient for activities under 60 min, calcium intake of 1300 mg/day is recommended for ages 9–18 years, vitamin D at least 600 IU/day for ages 1–18 years, and iron supplementation is recommended for deficiency or anemia. Supplement use is common in young athletes (82.2% in one study, 60.6% male; 43 of 44 swimmers reported at least one dietary supplement), while eating disorder data include 44.9% of 78 elite swimmers positive on at least one ED questionnaire, 24% of 36 female figure skaters with a clinically significant ED, and 11% of females versus 3% of males in elite handball.

Methods

  • Narrative review; MEDLINE–PubMed was searched for publications from 1990 to 2024, including randomized placebo-controlled trials, controlled clinical trials, double-blind randomized controlled studies, and systematic reviews.
  • Keywords combined nutrition/nutritional habits, children/adolescents/pediatric, physical activity/non-competitive sports/elite sport/eating disorders/dietary patterns/food supplements/energy drinks/sports drinks; reference lists were manually searched, and only English-language full papers were included.
  • The paper synthesizes guidelines, position statements, trials, and observational studies rather than conducting a systematic review or meta-analysis.

Limitations

  • The paper states that there is a lack of randomized controlled trials on creatine safety in adolescents, little data on protein demand in elite young athletes, limited evidence on sports drinks among adolescent athletes, and a lack of rigorous studies on omega-3 supplements in pediatric athletes; it also notes inconsistent findings on supplement prevalence and calls for larger sample sizes and longer observation periods.
  • It is a narrative review, not a systematic review, with no described risk-of-bias assessment or formal quality appraisal; this limitation is evident from the text.
  • Many recommendations are drawn from adult athletes or general public health guidelines because pediatric-specific evidence is limited; the paper states, for example, that most available protein-demand studies refer to the adult population and that competitive adolescent athletes should follow elite adult athletes’ protein guidelines.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

A language model drew the claims from the paper on 2026-11-14, under version 3 of the claim definition (model deepseek-v4.1-flash, prompt extract-v3).

A second model labelled each claim on 2026-11-14 (model jev-1.13-20260917, definition revision gold-guideline-v0.2).

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
