Analyses of the following biochemical markers were carried out: total and bone alkaline phosphatase (tALP and bALP), osteocalcin, tartrate-resistant acid phosphatase (TRAP), type I collagen carboxy terminal telopeptide, lipids, calcium, 25-hydroxyvitamin D, insulin-like growth factor 1 (IGF-1), thyroid-stimulating hormone, free thyroxin and intact parathormone.Results: There was a significantly greater increase in serum IGF-1 in G-III than in G II (p < 0.01) or G-I (p < 0.05) during the study period, and a significantly greater increase in plasma tALP in G-III than in G-I (p < 0.05). Serum bALP behavior significantly (p < 0.05) differed between G-II (increase) and G-I (decrease). Plasma TRAP behavior significantly differed between G-II and G-I (p < 0.01) and between G-III and G-II (p < 0.05).Conclusion: Daily dietary intake of hydrolyzed collagen seems to have a potential role in enhancing bone remodeling at key stages of growth and development. %K Bone %K Children %K Protein %K Proteínas en la Dieta %K Colágeno Tipo I %K Marcadores Biológicos %K Fosfatasa Alcalina %K Niño %K Remodelación Ósea %K Proteínas en la Dieta %K Pruebas de Química Clínica %K Fuerza de la Mano %K Dieta %K Hidrólisis %K Femenino %K Masculino %K Humano %K España %K Pubertad %~
