ABSTRACT
The quantification and development of physical qualities of youth rugby players is vital to support athlete preparation and long-term development. This chapter summarises and presents the research quantifying the physical qualities and their development of male youth rugby union and rugby league players and compares between age grades and playing positions, whilst considering the effect on career attainment and coaches’ perspectives. A range of research presents the physical qualities of youth rugby players, including stature, body mass, body fat percentage, muscular strength, muscular power, linear speed, change of direction, and aerobic capacity. Differences are apparent by age grade and position. However, the research has several limitations, including the presentation of small sample sizes and lack of consistency in the measures used. Future research should consider the use of national standardised testing batteries due to the inconsistency in testing methods and small samples limiting the reporting of positional differences. Practitioners can use the results from this review to evaluate the physical qualities of youth rugby players to enhance training prescription and goal setting.
