Dynamic balance is often assessed in athletes using either the Star Excursion Balance Test (SEBT) or the Y Balance Test (YBT). There is evidence that the results for the three common directions are not comparable. Thus, the question is open to debate as to which instrument is better suited to measure training-induced changes over time. The aim of this study is to compare the changes in the SEBT and the YBT, measured before and after six weeks of balance and strength exercise programmes in young and healthy athletes. A total of 30 young male athletes aged 15–17 years participated in this study and were involved in a six-week combined training, including balance and strength exercises. During pre- and post-training periods, the SEBT and YBT were conducted in random order. Paired-samples T-test was conducted to compare the changes in reach distances in dominant lower extremity between both tests. Pearson correlations, Bland–Altman assessment for agreement, and paired sample T-test were used to compare SEBT and YBT performance. The comparison between the changes in the SEBT and YBT with a paired sample T-test showed a significant increase in PM (P = 0.001) and PL reach directions (P = 0.000). No differences were observed in the A reach direction (P = 0.38). Based on our results, the conclusion that the responsiveness levels of the SEBT and YBT are similar is valid. Also, because of higher effect size value in the anterior direction in YBT compared with SEBT, this balance test could possibly be preferred in this direction for postural control evaluation.



Both Star Excursion Balance Test and Y Balance Test can be recommended for the evaluation of exercise programmes.
