Efeitos de mobilizações e fortalecimento do foot core em praticantes de levantamento de peso olímpico.

Abstract

ABSTRACT: The Foot Core are a group of intrinsic muscles of the foot, acting in stabilization and force transference. Restrained in modern typical footwear, the Foot Core doesn’t receive the necessary stimuli to keep its function. OBJECTIVE: To identify the effects of a myofascial release and muscular training protocol aimed towards function and performance of the Foot Core in Olympic Weightlifting practitioners. METHOD: Series of cases, with a sample selected based on convenience, all practitioners of Olympic Weightlifting in a CrossFit box located in the center of Rio Grande do Sul. The FAOS questionnaire, the Navicular Drop Test and a 1RM test in the Front Squat exercise were applied, before and after the intervention protocol. The protocol was authorial and was composed by the Short Foot exercise, mobilizations with a Lacrosse ball, the use of Toe Spreaders and time spent barefoot. RESULTS: Three male participants, between the ages of 18 and 36. All presented less symptoms of dysfunction expressed by the FAOS questionnaire, especially in the “symptoms”, “functional recreation” and “living daily activities”. During assessment, subject A had excessive pronation of the right foot arch, but in reassessment the subject no longer had this condition present. Subjects B and C presented a lesser height difference in their foot arches during reassessment comparing to values obtained in assessment. Neither subject presented excessive plantar pronation during reassessment. All subjects had an increment of load in the Front Squat 1RM after intervention. CONCLUSION: The developed training protocol was effective in treating pain and other symptoms of Foot Core dysfunction, reducing excessive plantar pronation and obtaining a better performance during the Front Squat exercise in Olympic Weightlifting practitioners.
