ABSTRACT
OBJECTIVES:
To investigate the effects of a foot training program on muscle morphology and strength as well as running biomechanics in healthy recreational runners.DESIGN:
Proof-of-concept, single-blind randomized controlled trial. SETTINGS Runners were allocated to a control (CG) or an intervention (IG) group. The intervention focused on strengthening the intrinsic foot muscles and their activation during weight-bearing activities. All participants were assessed at baseline and after 8-weeks.PARTICIPANTS:
Twenty-eight healthy recreational long-distance runners not habituated to minimalist running shoes or barefoot running. MAIN OUTCOMESMEASURES:
Outcomes were hallux and toes strength; foot function, cross-sectional area and volume of the abductor hallucis (ABH), abductor digiti minimi (ABV), flexor digitorum brevis (FDB), and flexor hallucis brevis; medial longitudinal arch range of motion and stiffness; vertical and antero-posterior propulsive impulses during running.RESULTS:
Compared to the CG, an increase was found in the IG for the volume of all muscles investigated and for vertical propulsive impulse during running. Correlations were found between vertical propulsive impulse and volume of ABH(r = 0.40), ABV(r = 0.41), and FDB(r = 0.69).CONCLUSION:
The foot exercise protocol effectively increased intrinsic foot muscle volume and propulsive forces in recreational runners. This shows that intrinsic muscle strengthening affects running mechanics and suggests that it may improve running performance.Palabras clave
