Im Leistungssport gibt es verpflichtende und verbindliche Eignungsuntersuchungen, die sicherstellen, dass der heranwachsende Sportler\/die heranwachsende Sportlerin den Anforderungen gewachsen ist. Derartig verpflichtende Untersuchungen vor Beginn der Ausbildung gibt es im Ballett nicht. F\u00fcr erwachsene professionelle T\u00e4nzer*innen konnten aus der tanzmedizinischen Literatur muskuloskelettale Idealma\u00dfe isoliert werden. Es gibt jedoch kaum Studien, die muskuloskelettale Eigenschaften professioneller Ballettsch\u00fcler*innen beschreiben, und es ist nicht bekannt, in welchem Alter ein professioneller Ballettsch\u00fcler\/eine professionelle Ballettsch\u00fclerin diese Ma\u00dfe erf\u00fcllen sollte oder welche Abweichungen als normal gelten. Die vorliegende Studie hatte das Ziel, die Population professioneller Ballettsch\u00fcler*innen soziodemografisch und muskuloskelettal zu beschreiben und er\u00f6rtert, inwiefern bereits heranwachsende professionelle Ballettsch\u00fcler*innen diese Idealma\u00dfe erf\u00fcllen bzw. davon abweichen.<\/jats:p><jats:p>\n            Methodik In dieser Studie wurden n=414 weibliche und n=192 m\u00e4nnliche Sch\u00fcler*innen der John Cranko School (JCS) im Alter von 5\u201322 Jahren (MW \u00b1SD: 13,9 \u00b13,5) durch eine erfahrene Orthop\u00e4din und Tanzmedizinerin anamnestisch aufgenommen (Alter, Nationalit\u00e4t, Beginn mit Ballett\/Ausbildung) und k\u00f6rperlich untersucht (K\u00f6rpergr\u00f6\u00dfe\/-gewicht, Symmetrie von Schulterg\u00fcrtel, Wirbels\u00e4ule und Taillendreiecken, Beckenstand\/-neigung, Tibiatorsion, Bewegungsausma\u00dfe von Zeigefingergrundgelenk, Wirbels\u00e4ule, H\u00fcften, oberen Sprung- und Gro\u00dfzehengrundgelenken). Anschlie\u00dfend wurden die Ergebnisse der vorliegenden Studie mit Eignungskriterien f\u00fcr klassische B\u00fchnent\u00e4nzer*innen abgeglichen, die f\u00fcr einen fr\u00fcheren Artikel aus der tanzmedizinischen Literatur isoliert werden konnten.<\/jats:p><jats:p>\n            Ergebnisse Untersuchte kamen aus 49 verschiedenen Nationen. 34,6% der weiblichen Untersuchten (\u226516 Jahre) waren zwischen 165 und 170cm und 33,3% der m\u00e4nnlichen (\u226518 Jahre) waren zwischen 178 und 185cm gro\u00df. 45,0% der Untersuchten zeigten ein Untergewicht (&lt;10. Perzentil, BMI &lt;18,5kg\/m\u00b2). Der Rumpf von 61,0\u201384,8% der Untersuchten war aufrecht und symmetrisch, 25,2% zeigten eine Skoliose. Die H\u00e4lfte (53,5%) ma\u00df eine beidseitige Au\u00dfenrotation der H\u00fcften von mindestens 60\u00b0 und 68,7% eine beidseitige Innenrotation zwischen 20 und 50\u00b0. 87,3% pr\u00e4sentierten eine beidseitige Tibiatorsion zwischen15 und 40\u00b0. Ein beidseitiges en dehors von 90\u00b0 konnte f\u00fcr 25,0% errechnet werden. Das obere Sprunggelenk von 49,1% der Untersuchten zeigte eine Dorsalextension von mindestens 25\u00b0 und von 70,2% eine Plantarflexion von mindestens 70\u00b0. Das Gro\u00dfzehengrundgelenk von 88,0% lag beidseits bei 90\u00b0 (w) bzw. 80\u00b0 (m)<\/jats:p><jats:p>\n            Diskussion Die Ergebnisse der vorliegenden Studie konnten zeigen, dass bereits professionelle Ballettsch\u00fcler*innen viele Merkmale erwachsener, professioneller Ballettt\u00e4nzer*innen erf\u00fcllen. Die hohen Werte schon in jungen Altersklassen legen eine ballettspezifische Selektion nahe. Dennoch erf\u00fcllen lange nicht alle Sch\u00fcler*innen die theoretischen \u201eIdealma\u00dfe\u201c f\u00fcr den klassischen B\u00fchnentanz. Diese anatomischen Grenzen sollten in der Ausbildung individuell ber\u00fccksichtigt werden, um die heranwachsenden professionellen Ballettt\u00e4nzer*innen zu sch\u00fctzen. Die hohen ballettspezifischen anatomischen Anspr\u00fcche, aber vor allem die gro\u00dfe Anzahl untergewichtiger Sch\u00fcler*innen unterstreichen die Notwendigkeit von verbindlichen Eignungsuntersuchungen zu Beginn und regelm\u00e4\u00dfigen Kontrolluntersuchungen im Verlauf der Ausbildung, um Kompensationsmechanismen und deren Folgesch\u00e4den abzuwenden und auf Essst\u00f6rungen und St\u00f6rungen des Essverhaltens zu screenen.<\/jats:p>","DOI":"10.1055\/a-2277-8400","type":"journal-article","created":{"date-parts":[[2024,4,25]],"date-time":"2024-04-25T22:53:00Z","timestamp":1714085580000},"page":"79-88","source":"Crossref","is-referenced-by-count":0,"title":["Tanzspezifische Eignung professioneller Ballettsch\u00fcler*innen \u2013 Untersuchungen an einer Ausbildungseinrichtung f\u00fcr klassischen B\u00fchnentanz"],"prefix":"10.1055","volume":"38","author":[{"given":"Tobias","family":"Almasi","sequence":"additional","affiliation":[{"name":"Institut f\u00fcr Arbeits-, Sozial- und Umweltmedizin, Goethe-Universit\u00e4t Frankfurt am Main Fachbereich 16 Medizin, Frankfurt am Main, GERMANY"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Elisabeth","family":"Exner-Grave","sequence":"additional","affiliation":[{"name":"Dezernat Gesundheit, Verbraucherschutz und Gefahrenabwehr \u2013 Schwerbehindertenangelegenheiten, Kreis Soest, Soest, GERMANY"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Daniela","family":"Ohlendorf","sequence":"additional","affiliation":[{"name":"Institut f\u00fcr Arbeits-, Sozial- und Umweltmedizin, Goethe-Universit\u00e4t Frankfurt am Main Fachbereich 16 Medizin, Frankfurt am Main, GERMANY"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"David A","family":"Groneberg","sequence":"additional","affiliation":[{"name":"Institut f\u00fcr Arbeits-, Sozial- und Umweltmedizin, Goethe-Universit\u00e4t Frankfurt am Main Fachbereich 16 Medizin, Frankfurt am Main, GERMANY"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Eileen M.","family":"Wanke","sequence":"additional","affiliation":[{"name":"Institut f\u00fcr Arbeits-, Sozial- und Umweltmedizin, Goethe-Universit\u00e4t Frankfurt am Main Fachbereich 16 Medizin, Frankfurt am Main, GERMANY"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"194","published-online":{"date-parts":[[2024,4,25]]},"reference":[{"volume-title":"Vom Tanz zum Ballett: Geschichte und Grundbegriffe des B\u00fchnentanzes. 2nd new rev.
