OBJECTIVES To longitudinally assess bone mineral content (BMC), bone mineral density (BMD), and whole-body lean mass obtained through bone densitometry by dual-energy X-ray absorptiometry (DXA) in preterm newborns (PTNs) and compare them with full-term newborns (FTNs) from birth to 6 months of corrected postnatal age. METHODS A total of 28 adequate for gestational age (AGA) newborns were stud...
b a ckground: previous studies have suggested that sex may be a factor influencing basal metabolic rate (bmr) in adults and school age children. however, few data are available about the effects of sex on bmr in pre-school children. in the present study, we investigated whether sex differences contribute to variations in bmr in pre-school age children. m et h o ds : measurements were made on th...
the phenomena of extensive air shower (eas) are produced by the collision of primary cosmic rays (cr) with energy more than ev with the atmospheric molecules. as a result the electron and muon components (cascades) of eas develop through the air. the study of such cascades gives important information about the primary cr mass composition as well as its astrophysical origin models. one of the e...
The purpose of this study was to determine the effects of body mass-based squat training on body composition, muscular strength and motor fitness in adolescent boys. Ninety-four boys (13.7 ± 0.6 yrs, 1.60 ± 0.09 m, 50.2 ± 9.6 kg) participated in this study and were randomly assigned to training (n = 36) or control (n = 58) groups. The training group completed body mass-based squat exercise trai...
Scale insects generally display enhanced survival rates in the presence of tending ants, but studies of ant and scale–insect interactions typically examine a single tending ant species. This study investigated the successive changes in tending ant species during the lifespan of two species of scale aggregations, a monophlebuline margarodid and an Eriococcus sp. (Eriococcidae) on the Plunkett ma...
PURPOSE An increase in the prevalence of obesity has been observed in children and adolescents. As remarkable changes in body composition occur with growth during the adolescent period, it is important that changes in body composition be monitored. The purpose of this study was to propose reference percentile values for body composition indices including body mass index (BMI) in children and ad...
OBJECTIVE To assess the association between the built environment and physical fitness and physical activity in adolescents. METHODS The study included 3528 adolescents, aged 12.5-17.5 years, who participated in the Healthy Lifestyle in Europe by Nutrition in Adolescence (HELENA) study. The health-related physical fitness components were assessed using the physical fitness tests. Participants...
