Are we built to run barefoot & how does it affect injury risk?

Barefoot running is a hot topic for recreational runners these days & we get asked at SPACE about this frequently. A recent presentation at the American College of Sports Medicine symposium asked whether barefoot running can increase or decrease skeletal injury risk?

Currently there have been no major studies have been completed to show whether barefoot runners are injured more or less often than those wearing standard shoes. However it is a fact that 80% of runners are still sidelined with an injury each year. 


Kinematic and kinetic analyses show that even on hard surfaces, barefoot runners who fore-foot strike generate smaller collision forces than shod rear-foot strikers.


The human mechanics of running are changed quite significantly when shoes are used opposed to natural, shoeless human running where the lateral edge of the forefoot is the part which strikes the ground with the most force. Running in padded shoes typically alters this as more emphasis is placed on the heel and the area towards the back of the foot.


The official position on barefoot running by the American Podiatric Medical Association states that there is not enough research on the immediate and long term benefits of the practice, and that individuals should consult a podiatrist with a strong background in sports medicine to make an informed decision on all aspects of their running and training programs. SPACE has one of these in the excellent Andy Paul whom has consultations on a Friday afternoon in Edinburgh's West End.

Backward motion helps injured knees

39 subjects were tested for muscle strength, cardiovascular fitness, balance & flexibility in a study presented at the recent American College of Sports Medicine Meeting in Denver, Colorado. After 24 sessions there was little difference exhibited between the forward & backward pedalling groups in balance and flexibility, but those who pedaled backward averaged about nine percent greater aerobic capacity and also measured higher in improvements in quadriceps and hamstring strength. 


Our colleague and erstwhile SPACE physio Olli Finlay alerted us to this study, and the effects of using elliptical machines for participants with knee pain. Lea author from the study was Elmarie Terblanche, Ph.D. who concluded that backward motion "can be a significant aid in rehabilitation to know how to most efficiently strengthen the joints and muscles after injury".
