What weight proportion do muscles represent at adolescence?

During adolescence, muscles typically represent about one-third of an individual's total body weight. At this stage of development, significant physiological changes occur, including an increase in muscle mass due to hormonal shifts such as those driven by puberty. This is particularly evident during this time when both males and females experience growth spurts and an increase in muscle strength and endurance.

In contrast, the other proportions, such as one-sixth, one-fourth, or one-fifth, do not accurately reflect the substantial contributions of muscle weight during this pivotal growth period. The approximate one-third proportion is grounded in research and observations of body composition trends in adolescents, making it a reliable figure for understanding muscle mass's role in overall body weight during this developmental stage.
