Take your shoes off to reduce patellofemoral joint stress during running
Barefoot running is a hot topic these days with many runners having tried it at some point. Barefoot running has been shown to alter foot-strike landing patterns and reduce knee extension moment, which in turn may be advantageous for reducing patellofemoral joint (PFJ) stress. PFJ stress reduction would be very important in runners, as their most common musculoskeletal complaint is patellofemoral pain syndrome (PFPS). The authors of this study hypothesized that barefoot running would reduce PFJ stress compared to shod running.
22 highly trained runners (14 male 8 female), averaging 33 miles/week were recruited. Candidates were excluded if they had any musculoskeletal or neurologic condition in the preceding 3 months. They performed 20 random running trials on an indoor track either barefoot or wearing the Nike LunaRacer. The authors found the barefoot runners had a significant reduction in PFJ stress along with shorter stride length and higher stride frequency.
Based on these findings, the authors thought barefoot running may reduce pain in people with PFPS due to the reduced PFJ stress, however, further studies are needed to confirm this. > From: Bonacci et al., Br J Sports Med 48 (2014) 425-428. All rights reserved to BMJ Publishing Group Ltd.
