 note = {The aim of this study was to investigate whether physical fitness influences the quantitative ultrasound (QUS) parameters in children. A total number of 693 school children, including of 343 boys and 350 girls, between 6-12 years of age were studied. Height, weight, foot length, and heel width were measured for an anthropometric analysis and the total score (fitness score) of the Japan fitness test, consisting of grip strength (kg), sit-up (times), sit and reach (cm), side step (points), 20 m shuttle run (times), standing long jump (cm), 50 m dash (sec), and ball throw (m), was used as an indicator for physical fitness. Broad-band ultrasound attenuation ( BUA) and velocity of sound (VOS) at calcaneus were measured as the QUS parameters using CUBA Clinical^<TM> Paediatric Research. The correlation coefficients and linear regression analyses revealed that a significant correlation existed between the QUS parameters and age, height, weight, foot length, heel width, and fitness score, respectively in both sexes except between heel width and VOS in girls. Multiple regression analyses were used to determine factors influencing the QUS parameters. In boys, the fitness score, weight, height, and heel width were independent predictors for BUA and fitness score, heel width, and height for VOS. In girls, weight, foot length, and fitness score were independent predictors for BUA and heel width, fitness score, weight, and foot length for VOS. In conclusion, physical fitness was found to have a significant influence on the QUS parameters in children., 論文},
