Strength, or resistance, training for young athletes has become
one of the most popular and rapidly evolving modes of enhancing
athletic performance. Early studies questioned both the safety
and the effectiveness of strength training for young athletes,
but current evidence indicates that both children and adolescents
can increase muscular strength as a consequence of strength
training. This increase in strength is largely related to the
intensity and volume of loading and appears to be the result
of increased neuromuscular activation and coordination, rather
than muscle hypertrophy. Training-induced strength gains are
largely reversible when the training is discontinued. There
is no current evidence to support the misconceptions that children
need androgens for strength gain or lose flexibility with training.
Given proper supervision and appropriate program design, young
athletes participating in resistance training can increase muscular
strength and do not appear to be at any greater risk of injury
than young athletes who have not undergone such training.
