Low back pain is complex and is a problem among cross-country skiers. Practitioners, trainers, and athletes should prevent the cause of it with a holistic approach. 

Welcome to The byrizz Rehab & Performance Podcast, episode number eight. In this episode, I speak to three Swedish high-level athletes competing at the highest level in cross-country skiing; Anna Dyvik, Jens Burman, and Viktor Thorn, who recently retired just 25 years old. In addition, we also have the privilege to be guested by Marcus Bystedt, Sports physiotherapist and strength and conditioning coach, working today as the primary winter sports contact at the Swedish Olympic Committee (SOK).

Episode #8 theme: Low back pain and prevalence among cross-country skiers.

Overload injuries are common in today's elite skier, where injuries in particular to the thoracic spine, chest and lower back are the most dominant. Study results indicate that years of long and repetitive flexion or extension do not increase the risk of low back pain (LBP). However, research shows that high loads during previous exercise cycles and previous episodes with LBP are risk factors for developing LBP. Previous injury and repetitive training are two commonly reported injury risk factors in endurance athletes. Insufficient consensus about the incidence of injury and the risk factors for injury in endurance sports is today actual—the prevalence of injury and its prevention. The knowledge about incidence and prevalence of injury at an early age, 12-19 years old, is limited, and in most sports, unknown.


  • Low back pain: background and athletes history of injury
  • What is low back pain to them, and what does the Sportsphysiotherapist mean about the prevalence and cause of injury?
  • Panel discussion: Being well-trained should be a key factor in succeeding as a cross-country skier, but how much of the essential training (core and injury prevention) is been done at younger ages? Is this necessary to minimize the potential risk of low back pain?
  • Do Swedish athletes train too hard and wrong? Should the training be more individualized rather than be "one size fits all"? 
  • Actual strategies from the athletes when it comes to preventing the risk of re-injury. How does this type of training day look like?
  • What is the upcoming training period for the athletes towards the Olympic Games in Bejing 2022?
