The purpose of the study was to model the longitudinal development of knee extension (KE) and flexion (KF) strength in adolescent soccer players. A mixed-longitudinal sample composed of 67 soccer players aged 11.0-13.9 years at baseline was followed on three-to-five occasions over 5 years. Stature, body mass and several skinfold thicknesses were measured. Fat mass was estimated from skinfolds and fat-free mass (FFM) derived. Skeletal age was estimated with the TW2-RUS protocol. An isokinetic dynamometer was used to obtain peak torque of KE and KF from concentric assessments at an angular velocity of 180°/s...

Meredith Wilson, Zaneta Thayer
BACKGROUND: Human biologists have a longstanding interest in understanding the biological and health impacts of migration. Acculturation, the cultural adjustment that a group or individual experiences when previously separate cultures interact, has been found to be one pathway through which migration may impact human biology and health, not only for the migrants themselves, but also their descendants. AIM: The authors conducted a pilot study to examine the relationship between acculturation and perceived stress, self-esteem and depression among young Middle-Eastern American adults...

BACKGROUND: This study relies on the discovery of two pit burials (LTA and LTB) of the Bronze Age Cogotas I archaeological culture (circa 3600-2950 BP) in Spain. LTA was a single burial and LTB contained three skeletal remains of two adults and a newborn or foetus at term. AIM: The central question posed by this find was whether the LTB tomb constituted a traditional nuclear family (father, mother and son or daughter). METHODS: Ancient and forensic DNA protocols were employed to obtain reliable results...
