Strength and Conditioning for Young Athletes

Rhodri Lloyd, PhD, is a Professor of Paediatric Strength and Conditioning and co‑founder of the Youth Physical Development Centre at Cardiff Metropolitan University, which offers after‑school strength and conditioning provision to around 200 young athletes. His research interests surround the impact of growth and maturation on long‑term athletic development and the neuromuscular mechanisms underpinning training adaptations and injury risk in youth. Rhodri has published more than 190 peer‑reviewed manuscripts, 40 book chapters, and 4 textbooks on the topics of paediatric strength and conditioning and long‑term athletic development, including the ACSM Essentials of Youth Fitness. He is a Fellow of the National Strength and Conditioning Association (NSCA) and has been recognised both nationally and internationally for his contributions to research and education, including the 2024 William J. Kraemer Outstanding Sport Scientist Award from the NSCA.Jon Oliver, PhD, is a Professor of Applied Paediatric Exercise Science, Associate Dean Research, and co‑founder of the Youth Physical Development Centre at Cardiff Metropolitan University. He is also an Adjunct Professor at the Sports Performance Research Institute New Zealand and Strength and Conditioning Research Lead for the Welsh Institute of Performance Science. He has been at the forefront of leading research and informing practice on the long‑term athletic development of youth. This has been supported by experimental research examining how growth and maturation interact with the development of physical fitness, responsiveness to training, injury risk, overtraining, and the health and well‑being of young athletes. Professor Oliver has collaborated with many schools and professional organisations nationally and internationally in a variety of youth sports, working with populations from grassroots to the elite level.
