    INTRODUCTION: The foot and ankle are responsible for absorb shock when heel hits the ground. During the movement, the arch flattens and the foot adapts in the ground. Because it, the foot suffer biomechanical changes from global changes in posture. These alterations may encourage injuries, which can be primary and secondary. Thus, physical therapy have been prioritized as a treatment to strengthen the intrinsic and extrinsic muscles, however, it is not justified through assessment with specific devices for measuring muscle strength. OBJECTIVE: To compare the strength of muscles dorsiflexors, plantar flexors, invertors and eversors in differents foot postures and to compare the strength of muscles between dominant(DLL) and nondominant lower limb (NLL). METHODS: 50 young people, both genders and with an average of 22,08 (2,56) years old were assessment. We selected volunteers with moderate level of physical activity, analyzed through the International Physical Activity Questionnaire (IPAQ). Initially, they were submitted to Foot Posture Index (FPI), which divided the foot into three groups: foot hiperpronated (GPH), pronated foot (GPP) and neutral foot (GPN). The groups GPH, GPP and GPN respectively were composed by: eight, 61 and 31 foots. Moreover, test for muscle strength was performed in the following muscles: triceps surae, plantar flexors, invertors, eversors and dorsiflexors, through manual dynamometer. The comparisons of muscle strength between groups and the comparisons between DLL and NLL were performed by analysis of variance (ANOVA) and through Bonferroni test for discrimar differences. Firstly, comparisons between the groups was performed without considering the dominance and then the test was repeated considering the side of the member. RESULTS: The invertors, evertors and dorsiflexors muscles in the GPH are stronger than the muscles in the GPN. Moreover, the plantar flexores and triceps surae muscles in the GPH are weaker than in the GPN. However, there was not statistically significant difference in the three groups, considering the dominance (p= 0.44, 0.68, 0.08, 0.42, 0.17, respectively) and without considering the dominance (p=0.83, 0.66, 0.78, 0.58, 0.34, respectively). There was no difference when comparing the muscle strength between the DLL and NLL, with p-values respectively equal to: 0.95, 0.90, 0.53, 0.30, 0.23. In the order side, the FPI had significantly difference (p=0.001) when compared between the three groups. CONCLUSION: The dorsiflexors, invertors and evertors muscles, in the highly foot pronated, are the trongest. The plantar flexors and triceps surae muscles, in the highly foot pronated, are the weakest. Furthermore, the dorsiflexors, invertors, evertors, plantar flexors and triceps surae muscles in the dominant side are stronger than the nondominant side.
