    The study analyzed cardiopulmonary exercise testing (CPET) metrics in 303 healthy children and adolescents across different age and sex groups.

  • 2

    Older age groups exhibited higher absolute peak values of oxygen consumption, work rate, and oxygen pulse, proportional to body size.

  • 3

    Weight-indexed peak values were comparable in males but significantly lower in older females compared to younger females.

  • 4

    Submaximal CPET parameters showed age-dependent trends in both sexes, with males demonstrating enhanced oxygenation efficiency with age.

  • 5

    Significant sex differences in exercise performance were noted in older adolescents, reflecting variations in growth and maturation.
