This review focuses on the hormonal responses to resistance training in pre-pubertal and pubertal males with the aim to elucidate possible mechanisms that may be responsible for the increases in strength and power following systematic training in these age groups. Studies that have controlled for the confounding effects of growth and motor skill acquisition, have shown that resistance training results in significant increases in muscular strength even before puberty. Although the training induced muscle hypertrophy in pre-pubescents is possible, it is much less compared that of post-pubescents. On the other hand an equal or greater improvement in neuromuscular activation, motor skill and intrinsic muscular adaptations are reported in the pre-pubescents compared to the post-pubescents following resistance training programs. Resting serum testosterone concentration has been found to increase following 2-12 month resistance training programs and this is accompanied with an increase in muscle strength. Changes in strength and hormonal concentrations depend on the characteristics of the resistance training program, with the most important being exercise intensity and volume.
