A recent paper has been published in the 'Physical Therapy in Sport journal' that has reviewed nine articles assessing the relationship between core stability and lower limb injury risk. The paper concludes that there is a link between impaired core stability and the development of lower limb injuries in healthy athletes.

This is certainly something I see clinically in my physiotherapy practice and why I always include core stability retraining with the athletes I work with.
Building core stability as part of an athletes (or anyone involved in sport) training program is an excellent way to to prevent lower limb and back injuries, something we call 'prehab'. I would encourage all athletes to build core stability training into their programmes.
In my injury prevention workouts, I focus on core stability and lower limb strength and control. All the key elements to injury prevention are included in these workouts.
