PUROPOSE: To assess the response in two different field balance tests, one static requiring hip mobility (SEBT) and one static and walking (USTB), to a strengthening protocols aimed at core strengthening and peripheral strengthening on a population of young female dancers. METHODS: 21 female dancers aged 6 - 14 years took part in the study. Mean age 9.6 ± 2.2 years, weight 38.3 ± 9.6 kg, height 140.4 ± 16.20 cm, sitting height 74,5 ± 7.8 cm, lower limb length 66.1 ± 8.4 cm. Subjects underwent a 24 weeks, twice per week, 1 hour ankles, legs and abdominals muscles strength training. The protocol consisted in crunches exercises, ankle exercises, hops and jumps as previously described. Subjects were tested in the pre and post training conditions with the static balance star excursion test (SEBT) and the US naval test battery (USTB), in a random order. Pre-post T test for paired samples was performed with the software SPSS v.21. RESULTS: The subjects shows an improvement between the pre and post test conditions both in the SEBT test (mean 2.3 cm, 2.1 - 2.7 cm range) than in the static USTB test, while showed a worsening in the USTB walking test (mean 5 s, mean 1 - 15) (Student T -7.17/-8.01 p < 0.001). Any correlation was found between the results of the two test batteries. CONCLUSIONS: We found the strengthening of core and ankle muscles to be effective in improving static balance in growing female dancers; we observed a significant improvement in both tests after a 24 week, 2 hours per week of training of abdominals, legs and ankles muscle groups. The SEBT and USTB tests showed to be totally independent each other in assessing body balance; any correlations between the tests results were found. This can be explained with the requirements of the two tests and with the involvement of hip mobility in the SEBT. Walking balance require specific training and it is not influenced by strength training of core and lower limbs in young dancers. When assessing balance in young dancers, it is reccomended to include a walking test, in order to have a complete profiling of balance capacities
