Skill Development

Peak Height Velocity (PHV) is used as a marker in identifying early, normal or late maturers, and as a guide for determining direction in training programs.

This diagram is an example of training programs related to maturation timing of on-time maturers (girls and boys). When an athlete is identified as an early or late maturer, his training schedule and regiment needs to shift accordingly.

2022 – Optimizing long-term athletic development: An investigation of practitioners’ knowledge, adherence, practices and challenges

Kevin Till, Rhodri S. Lloyd, Sam McCormack, Graham Williams, Joseph Baker, Joey C. Eisenmann

PLOS ONE 17(1): e0262995

Conclusion: These novel findings can help inform policy to optimize long-term athletic development and to support the complex problem of developing a healthier, fitter and more physically active youth population

2021 – Estimating is not measuring: the use of non-invasive estimations of somatic maturity in youth football

Job Fransen, Sabrina Skorski, Adam Dominic George Baxter-Jones

Conclusion: Researchers and practitioners should carefully … assign players into categories (i.e. pre, circum or post puberty), which can, alongside players’ chronological age, offer valuable insights to … practitioners concerned with football players’ growth and development.

2021 – Youth injuries – Gymnastics, A large percentage of injuries are overuse & over training in gymnastics, with risk typically increasing with age and competition level! Increasing lower limb strength and improving jumping & landing mechanics would help decrease the risk of injury!

2022 – YOUTH INJURIES – FOOTBALL, a quick breakdown of common injuries in youth football! 66% of injuries are ‘non-contact’, this includes sprinting, changing direction & ball striking! Strength training can help improve the bodies ability to cope with physical & locomotor demands!

2021 – YOUTH INJURIES – ’THROWERS’ SHOULDER. This stress injury to the proximal humeral growth plate is prevalent across many sports with repetitive overhead movements! Strengthening shoulder tissues & managing load along with improving throwing mechanics will help reduce prevalence!

2022 – YOUTH INJURIES – RUGBY UNION

As the start of the rugby season gets closer it’s important we understand how many common injuries occur! Strength training can help reduce injury risk by developing locomotor skills, single leg stability & increasing structural load tolerance!

2022 – The influence of exposure, growth and maturation on injury risk in male academy football players

David M. Johnson a,b, Sean P Cumming a , Ben Bradleyb and Sean Williams,

 a Department for Health, University of Bath, Bath, UK; b Academy Sports Science and Medicine Department, AFC Bournemouth, Bournemouth, UK

A heat map showing the combined effects of growth rate and percentage of predicted adult stature on estimated a) injury likelihood and b) injury burden

Conclusion: Practitioners should monitor the timing and rate of the growth spurt and exposure time to identify players at greater injury risk.

Training Load

2022 – Training Load dose-responses in adolescent male football: the importance of biological maturation

Jamie Salter, PhD ASCC CSci Senior Lecturer at York St John University United Kingdom

Conclusion: Practitioners should actively seek opportunities to integrate biologically classified training activity alongside chronologically categorized sessions within their training schedules. In doing so they may alleviate the consistent stress placed on less mature players as part of standard chronologically categorized sessions without compromising the development of those more mature and able to tolerate greater workloads.

2022 – Maturity status influences perceived training load and neuromuscular performance during an academy soccer season

Jamie Salter, Ross Julian, Stijn V. Mentzel, Alastair Hamilton, Jonathan D. Hughes & Mark De St Croix (2022):, Research in Sports Medicine, DOI: 10.1080/15438627.2022.2102916

Conclusion: Maturity-specific load prescription may prevent significant within age-group differences in accumulated load, possibly reducing injury risk and/or burnout.

Relative Age

2021 – Maturity Has a Greater Association than Relative Age with Physical Performance in English Male Academy Soccer Players

John M. Radnor, Jacob Staines, James Bevan, Sean P. Cumming, Adam L. Kelly, Rhodri S. Lloyd and Jon L. Oliver

Conclusion: Maturity status should be considered when comparing fitness scores in players to ensure practitioners are not comparing early and late maturers within the same age group, but rather are comparing boys of the same maturity status
