What is a result of resistance training in adolescents?

Research consistently shows that resistance training in adolescents produces significant gains in muscular strength, primarily through neural adaptations such as improved motor unit recruitment and coordination rather than muscle hypertrophy. Major organizations including the NSCA and AAP recognize supervised resistance training as safe and beneficial for youth when properly designed.

Adolescents, particularly pre-pubescent youth, do not significantly increase muscular bulk from resistance training because they lack sufficient circulating anabolic hormones such as testosterone to drive substantial hypertrophy.

Resistance training actually has a positive effect on bone mineral density, reducing osteoporosis risk rather than increasing it, due to the mechanical loading stimulus on bone tissue.

Properly supervised and age-appropriate resistance training does not cause permanent musculoskeletal damage; this is a widely debunked myth, and evidence supports its safety for adolescents.
