The purpose of this study was to define the optimal lower-limb flexibility data for 20 female futsal players. Therefore, the flexibility of the major lower-limb muscles was evaluated throughout 7 different passive range of motion (ROM) assessment tests. The results of this study define the optimal ROM ranges for field players as: 43º-52º for the gastrocnemius, 48º-54º for the soleus, 148º-154º for the gluteus maximus, 99º-118º for the hamstrings, 46º-56º for the adductors, 12º-20º for the iliopsoas, and 116º-129º for the quadriceps. For goalkeepers have obtained the following ranges: 40º-46º for the gastrocnemius, 40º-47º for the soleus, 150º-155º for the gluteus, 94º-118º for the hamstrings, 45º-54º for the adductors, 8º-12º for the iliopsoas, and 115º-133º for the quadriceps. Keeping in mind that optimal ROM values were defined as >80th percentile, only 4 field players and 2 goalkeepers presented this ROM values in each movement assessed .
