What is it about?
This study demonstrates the crucial influence of prtein intake on the response to enhanced physical activity and the importance of prepubertal years for modifiying, by environmental factors, the bone growth trajectory and, thereby, for achieving higher peak bone mass and greater strength in healthy male subjects.

Why is it important?
This over 15 year prospective study, from 7.4 to 22.6 years, shows the tracking of interactive envionmental determinants of peak bone mass and strength in a cohort of healthy males. It complements and corroborates findings of two previous reports that describe the positive effect of protein intake on the bone response to higher physical activity. In these two previous analyses conducted in boys belonging to the same cohort, the protein but not the calcium intake influenced the bone impact of increased physical activity.
Perspectives
The results further pinpoint the importance of prepubertal years for modifiying the bone growth trajectory through environmental factors and, thereby, for achieving higher peak bone mass and strength in healthy male subjects.
