Biological maturation determines the beneficial effects of high-intensity functional training on cardiorespiratory fitness in male adolescents.

ABSTRACT:

Background

During adolescence, between 15-18 years of age, biological maturation is associated with changes in body composition, blood pressure (BP), and cardiorespiratory fitness (CRF). Also, environmental factors may influence the trajectory of these changes. The rising prevalence of physical inactivity calls for the identification of effective exercise modalities to mitigate adverse health outcomes in youth. Although high-intensity training regimens are increasingly recognized for their benefits in school settings, the specific role of biological maturation in determining adolescent responses to such intervention in health outcomes remains insufficiently understood.

Aim

This quasi-experimental study investigated the effects of chronological age (CA) and maturity offset (M
