Physical Activity, Dietary Intake and Bone Status in 6-12 Years Children

The sample of this study was healthy pre-pubertal boys and girls (N=210) who had training age 0-1 years. Data collection included anthropometric measurements, blood sampling, body composition, bone measurements and physical performance measurements. Nutritional intake was recorded for seven consecutive days in order to evaluate nutrient intakes using an appropriate software and habitual physical activity was measured for the same days using accelerometers. Pubertal stage determined by Tanner scale. All measurements were made only once at the beginning of school year.
