Summary

Intensive sports training, particularly ballet, can negatively impact young female dancers' growth and puberty. Inadequate nutrition and disordered eating are linked to delayed development in these athletes.

Area of Science:

  • Sports Medicine
  • Pediatric Endocrinology
  • Sports Nutrition

Background:

  • Intensive training in sports emphasizing aesthetics may affect adolescent development.
  • The long-term consequences of early-onset training on growth and puberty are not fully understood.
  • Female athletes in sports like ballet face unique pressures regarding body composition and performance.

Purpose of the Study:

  • To investigate the longitudinal effects of intensive sports training on growth and pubertal development in young female dancers.
  • To compare the physical development of dancers with a control group over a five-year period.
  • To identify potential risk factors associated with training-related developmental changes.

Main Methods:

  • Longitudinal study of 97 young female dancers over 5 years.

  • Monitoring of height, weight, and pubertal development.
  • Comparison with a non-athletic control group.

    • Main Results:

    • 16% of dancers exhibited decreased growth velocity during pre-puberty.
    • Delayed puberty was observed in dancers compared to controls.
    • Dancers with reduced growth and delayed puberty had inadequate nutritional intake and were slimmer, despite similar training durations.

    Conclusions:

    • Moderately intensive dance practice can contribute to eating disorders and weight control issues in childhood.
    • These issues may have significant, yet poorly understood, consequences on physical development.
    • Monitoring weight and height in child athletes involved in aesthetic sports is crucial for early detection of anomalies.
