A kinetic analysis of the triple step in recreational swing dancers.

Despite its increasing popularity, swing dancing has not been fully studied biomechanically, imposing challenges in understanding the movement patterns associated with swing dancing. The purpose of this study was to examine the biomechanics of the triple step, one of the most common swing dance elements. We intended to determine whether dancing with a partner affects kinetic measurements and if these measurements are different among the three steps. Eight recreational swing dancers completed three triple steps to the right and the left with and without a partner. The loading rate of the vertical ground reaction force was calculated for each step, and bilateral lower limb joints moments and powers were determined. Results illustrated that dancing with or without a partner has limited effect on the kinetic measurements. However, the outcome measurements differed among the steps: a higher peak vertical ground reaction force during the first and second steps, a greater loading rate during the second step, and the greatest joint power absorption at the ankle and knee during the second step were observed. The findings extend our understanding of the biomechanics of swing dancing, and could provide preliminary guidance for understanding swing dance-related injuries and improving performance of swing dancing.
