Around the world, the way that young talent is identified is often done without an understanding of how young athletes develop. We talk to Norwegian researcher in the field, Eirik Halvorsen Wik, PhD, from Cape Town's Institute of Sport and Exercise Medicine at Stellenbosch University, for a close look at the challenges faced by young sporting stars, why there may be a better way to make selections at youth level and how to ensure the best athletes are given the best chance at long term success. Wik has previously worked at the Norwegian School of Sport Sciences and the Oslo Sports Trauma Research Centre.SHOW NOTES:A news story on the Ultra runner who took a car trip for 2.5 miles mid raceThe paper in which coaches are revealed as not being all that good at spotting good running economyOur guest Eirik Wik’s study on injuries in adolescent athletesAnother paper published by Dr Wik, describing different injuries with age in elite adolescent footballers:

Mental and muscle fatigue is part of every sporting endeavour. But what is fatigue? What happens in the body when we get tired and is it possible to push beyond our perceived limits?

Respected sports journalist and writer Clinton van der Berg talks about his journey writing his book 'Guns And Needles: A Journey into the heart of South Africa's sport's steroid and drug culture." Van der Berg shares how he managed to get sports people, accused and convicted of doping, to tell their story; how he found out about the shocking incidences of doping in school and junior sport and why both young and old are susceptible to the performance benefits of illegal supplements and drugs. It's a cautionary tale for amateurs and professionals alike no matter what country you come from.Note: We are aware the sound on this one from Clinton is really poor. We had major connectivity problems over the recording and try as we might to correct it post-recording, we just couldn't. We are really sorry, it's hugely frustrating and does detract from the listen and the content. We can only apologize for it and commit to making sure it doesn't happen again in future.
