We proposed a randomized, prospective controlled and parallel clinical trial with blind assessment aiming to establish prophylactic measures for recreational runners while improving foot-ankle functionality and biomechanics.
To evaluate the feasibility of the proposed exercise protocol, and the effectiveness of the protocol on foot health and functionality, foot muscle trophism, and forces while running.

In general, better performance of the intervention group than the control subject
• CG = S005
• IG = S002, S003, S004
Intervention protocol
IN SUMMARY
• The protocol is Feasible;
• The population is interested and accessible;
• Results suggests certain biomechanical alterations on IG despite the short sample;
• Investigate foot dynamic deformation according to Perl et al. (2012);
• Improve the training protocol making it shorter;
• Calculate injury incidence in 12 months and 1000 hours of practice;
• Follow a larger sample (n=111).
