Introdução: o crossfit engloba variadas competências físicas, sendo o agachamento um gesto frequente desta modalidade que para ser executado corretamente é necessário ampla amplitude de dorsiflexão do tornozelo. Objetivo: verificar se a técnica de auto-mobilização de Mulligan (A-MWM) com a utilização de um cinto promove alterações na amplitude de movimento de dorsiflexão do tornozelo em atletas de crossfit. Metodologia: 33 participantes (19-54 anos), de ambos os sexos, praticantes da modalidade de crossfit com o mínimo de 3 treinos por semana, sem histórico de lesão nos membros inferiores, foram avaliados através do Weight-Bearing Ankle Dorsiflexion, no início do protocolo e após 4 semanas. Os participantes foram alocados aleatoriamente em 2 grupos: grupo de intervenção (A-MWM com cinto) e grupo placebo (A-MWM com Theraband com mínimo de tensão). Resultados: a amplitude de movimento ativa de dorsiflexão em ambos os tornozelos melhorou significativamente em cada um dos grupos após 4 semanas (0,015<p<0,077), no entanto não se verificaram diferenças com valor estatístico entre os ganhos de cada grupo(p=0,875 no pé dominante e p=0,570 no não dominante). Conclusão: a técnica de A-MWM com cinto não se mostrou efetiva no ganho de dorsiflexão em atletas de crossfit.
Introduction: crossfit includes several physical skills, and the squat is a frequent gesture of this sport that requires a wide range of ankle dorsiflexion to be executed correctly. Objective: To verify if Mulligan's self-mobilization technique (A-MWM) using a belt promotes changes in ankle dorsiflexion range of motion in crossfit athletes. Methodology: 33 participants (19-54 years old), of both sexes, practicing crossfit with a minimum of 3 workouts per week, with no history of lower limb injury, were evaluated using the Weight-Bearing Ankle Dorsiflexion at the beginning of the protocol and after 4 weeks. Participants were randomly allocated into 2 groups: intervention group (A-MWM with belt) and placebo group (A-MWM with Theraband with minimal tension). Results: Active dorsiflexion range of motion in both ankles improved significantly in each of the groups after 4 weeks (0,015<p<0,077), however, there were no statistically significant differences between the gains of each group (p=0.875 for the dominant foot and p=0.570 for the non-dominant foot).Conclusion: the A-MWM technique with a belt was not effective in increasing dorsiflexion in crossfit athletes.
