- Abstract
The physical effort of athletes has been widely studied e.g. in soccer (Bangsbo, Krustrup and Mohr, 2006), but has not received much attention in dance. Consequently the physical demands of six ballroom (BR) dance couples (three adult International couples ("Adult") and three elite youth couples ("Youth")) were analysed when performing BR dances. The dances were recorded directly onto DVD using one camera located directly above the dance floor at a frequency of 25 frames per second. The recordings were analysed with the SAGIT tracking system to determine the trajectories, distance and speed of the dancers. A comparison of the Adult and Youth couples' trajectories showed that the younger, less experienced dancers used the basic choreographic form through the circle while the Adult couples consistently used the inner space of the dance floor. The biggest differences between the two sets of dancers were found in the Waltz, Tango and Quickstep. The dynamics of movement (distance covered and speed) tended to decrease in line with the experience of the dancing couple involved. The Adult couples made longer and faster trips than the Youth couples for all dances except the Foxtrot. These performance differences seemed to relate to the softness in the complex movements which was apparent in the speed of the Adult dancers whereas the simpler movements of the Youth dancers did not allow this feature to be distinguished.
