THE EFFECT OF PHYSICAL GROWTH, BIOLOGICAL MATURATION AND ETHNICITY ON CARDIAC PRE-PARTICIPATION SCREENING IN MALE PAEDIATRIC ATHLETES
… investigations, Study 3 (Chapter 6), employed ‘biological’ age (by radiological X-ray) assessment to T-wave inversion (TWI) interpretation on the paediatric athletes ECG. TWI confined to V1–V3 was predicted by black ethnicity and biological age <16 years, but not chronological age <16 years. …

The effects of biological maturation and training experience in upper and lower limb power of young basketball, football and handball players
Σκοπός της παρούσας μελέτης ήταν η διερεύνηση της επίδρασης της χρονολογικής ηλικίας, της βιολογικής ωρίμανσης και της προπονητικής εμπειρίας, στην ισχύ άνω και κάτω άκρων σε αθλητές καλαθοσφαίρισης, χειροσφαίρισης και ποδοσφαίρου. Ειδικότερα, εξετάστηκαν οι διαφορές μεταξύ αθλητών 13 και 14 ετών …

An exploration of one former elite UK football academy player’s lived experience of ‘being bio-banded’, through narrative inquiry: A focus on body- self relationships and identity construction
… the process of grouping players based on biological maturation as opposed to chronological age, led the focus of inquiry where early maturing players are chosen to ‘play-up’. To date we know very little about the experience and long-term impact of being ‘bio-banded’ on academy footballers. …

Selection biases within an English football academy: implications of the Elite Player Performance Plan
… literature demonstrates that relative age and biological maturation are responsible for selection biases within youth football, where both factors exert an influence on anthropometry and physical performances. However, there is limited research that has examined the aforementioned factors over …

Teenage Clumsiness: Does it exist?
… their body size and movement was influenced by biological maturation, and whether adolescent awkwardness could be detected in performance of sport specific skills independent of strength. An endpoint matching task was used to measure awareness of foot position in space by measuring the distance …

Assessing the applicability of the Greulich and Pyle (1959) skeletal age estimation method to South African children between 0 and 13 years
… serves to estimate the degree of development and biological maturation of a child. This is a suitable and frequently used technique, as skeletal age is a valuable indicator which can be analysed from birth until the attainment of the fully-developed adult body form. Radiographs of the hand-wrist …

Standards for epiphyseal union in South African children between the ages of 6 to 24 years using low dose X-ray (lodox)
Skeletal age is a measure of biological maturation and is based on the stages of formation of bones. As age increases, skeletal maturation progresses and the various hard tissue changes which take place are uniquely identifiable and defining to each stage of development. Age assessment using …

Maturation, playing position and genetic variation: injury risk factors in high-level youth soccer
… varied in YSP between different nations; (ii) if maturation status, playing position and/or genetic variation were associated with injury risk in YSP. The injury audit (Chapter Three) revealed that non-contact injuries to skeletal muscle were amongst those frequently recorded, with most injuries …
