The purpose of this study was to examine the transversus abdominis and lumbar multifidus thickness among Argentine Tango dancers in different functional dance positions. A secondary purpose was to compare muscle thickness at rest and contraction between dancers and untrained participants. Ten trained dancers and ten untrained women aged 33.8 ± 6.09 years participated in this study. Using ultrasonography, the transversus abdominis and lumbar multifidus muscle thickness were measured at rest and during contraction in three different dance positions: Basic in Open embrace, Basic in Close embrace, and Volcada. The results showed a significant increase in muscle thickness during contraction compared to thickness at rest for both muscles (p < 0.05). The group of dancers showed a greater transversus abdominis thickness than the untrained group (p < 0.05). Further, transversus abdominal thickness progressively increased from Basic in Open embrace to Basic in Close embrace position, as well as from Basic in Close embrace to Volcada position in dancers (p < 0.05), while fewer changes between positions were found for the untrained group. Multifidus muscle thickness also differed between positions, but no group differences were observed (p > 0.05). Training exercises in these Argentine Tango positions may be beneficial for the performance and prevention of low back pain, especially in Argentine Tango dancers.
