Abstract Objective: A high unilateral load to the musculoskeletal system is specific for formation dance. Due to the lack of data the aim of this study was the side-related (right – left) analysis of strength- and balance capability subject to injuries, gender and performance standards. Methods: N = 51 dancers (m: n = 24, f: m = 27) of two performance levels participated in this cross-sectional study. Double-sided tests of the isometric maximal strength of relevant muscle groups and the balance capability were carried out. The tests were supplemented by a self report questionnaire. Results: Tests of the isometric maximal strength in the elite performance level showed significant differences between either side of the body. As to the balance capability, no significant side-related differences could be found in. Correlations between the strength capability and the injuries could be observed in either group. Conclusion: The significant strength differences are presumably caused by the right-sided load in the dancespecific movements. The cautious conclusion that movement patterns challenge the stability of either side of the body likewise may be allowed. The increased injury frequency at the muscularly stronger side of the body primarily results from an overload. An additive muscular training should be considered as a preventive measure.

Background Dance sport is the competition- and performance-oriented variant of ballroom dancing. Within dance sport, which is one of the technical/compositional and aesthetic sports, formation dance is a further discipline in addition to single-pair dance [1]. As a result of the 1950s, formation dance sport has become established in its present form with a 5-level league system and annual national and international championships. As in single pair dancing, a distinction is made between standard and Latin American formations. The aim of formation dancing is to have the 8 couples of a team moving synchronously and precisely on the dance floor during the five Latin American dances (Samba, Rumba, Jive, Cha-Cha-Cha, Paso Doble) [2]. In contrast to the single pair dance, a performance in formation dance lasts six minutes, 4.5 min of which are allotted to the main part relevant for the evaluation with the * Correspondence: [email protected] 1 Institute of Occupational, Social and Environmental Medicine, Goethe-University Frankfurt Main, Theodor-Stern-Kai 7, 60590 Frankfurt am Main, Germany Full list of author information is available at the end of the article

Jive) into the maximum stress range, with high demands being conductive to injuries [3, 4]. In contrast to single pair dance, there are formation dance-characteristic element
