Area of Science:

  • Endocrinology
  • Adolescent Medicine
  • Sports Physiology

Background:

  • Male adolescent development involves significant physical changes driven by hormonal axes.
  • Understanding the interplay between energy balance and these axes is crucial for adolescent health.

Purpose of the Study:

  • To describe physical growth and sexual maturation in adolescent males.
  • To elucidate the roles of the hypothalamic-pituitary gonadal and GH/IGF-I axes.
  • To examine the impact of high energy output with low energy input, using scholastic wrestlers as a model.

Main Methods:

  • Review of physiological changes during male adolescence.
  • Description of hormonal axis function (hypothalamic-pituitary gonadal, GH/IGF-I).
  • Analysis of energy balance in athletic adolescent populations.

Main Results:

  • Adolescent males undergo distinct pubertal development stages.
  • Hormonal axes orchestrate growth, sexual maturation, and body composition changes.
  • Scholastic wrestlers exemplify how extreme energy demands can interact with pubertal development.

Conclusions:

  • Male adolescent development is a tightly regulated endocrine process.
  • Energy availability significantly influences the hormonal regulation of growth and sexual maturation.
  • Further research is needed on the long-term effects of energy imbalance in adolescent athletes.
