Adolescents are categorized into which age range?

Adolescents are typically defined as individuals in the age range of 10 to 19 years, which encompasses early adolescence (ages 10–14) and late adolescence (ages 15–19). The correct choice of 13-18 aligns most closely with the broader understanding of this developmental stage. During these years, adolescents go through significant physical, cognitive, social, and emotional changes, marking a transitional phase from childhood to adulthood.

While the other options may capture some aspects of adolescent development, they do not align as comprehensively with the recognized age range. For instance, the option that identifies ages 15-20 extends beyond the typical classification, as late adolescence usually concludes around age 19. Understanding this age range is crucial for exercise physiologists and health professionals, as it allows for the designing of age-appropriate interventions and programs that address the unique physiological and psychological needs of adolescents.
