Land like a Dancer

[Michie 1.228]

In dem Video geht's darum, dass Athleten viel öfter ihre Sprunggelenke verletzen als Tänzer, obwohl beide oft springen und - unausweichlich - oft landen. Die Unterschiede der Landetechniken werden kurz erörtert, ich schätz es gibt dazu dann auch noch weiterführende Studien, die sicherlich interessant durchzulesen sind:

Video ist mittlerweile leider privat

schwer genial

Die Trainieren auch kompllet anders, das ist drill bei denen!

Barbara kann davon viel berichten als ex-Staatsopern Ballet Tänzerin

Comparison of landing biomechanics between male and female dancers and athletes, part 1: Influence of sex on risk of anterior cruciate ligament injury.
Orishimo KF, Liederbach M, Kremenic IJ, Hagins M, Pappas E.
Am J Sports Med. 2014 May;42(5):1082-8. doi: 10.1177/0363546514523928. Epub 2014 Mar 3.
PMID: 24590005 [PubMed - in process]
 
BACKGROUND:

The incidence of anterior cruciate ligament (ACL) injuries among dancers is much lower than among team sport athletes, and no clear disparity between sexes has been reported in the dance population. Although numerous studies have observed differences in landing biomechanics of the lower extremity between male and female team sport athletes, there is currently little research examining the landing biomechanics of male and female dancers and none comparing athletes to dancers. Comparing the landing biomechanics within these populations may help explain the lower overall ACL injury rates and lack of sex disparity.

RESULTS:

Dancers of both sexes and male team sport athletes landed similarly in terms of frontal-plane knee alignment, whereas female team sport athletes landed with a significantly greater peak knee valgus (P = .007). Female dancers were found to have a lower hip adduction torque than those of the other 3 groups (P = .003). Dancers (male and female) exhibited a lower trunk side flexion (P = .002) and lower trunk forward flexion (P = .032) compared with team sport athletes.

CONCLUSION:

In executing a 30-cm drop landing, female team sport athletes displayed a greater knee valgus than did the other 3 groups. Dancers exhibited better trunk stability than did athletes.



Comparison of landing biomechanics between male and female dancers and athletes, part 2: Influence of fatigue and implications for anterior cruciate ligament injury.
Liederbach M, Kremenic IJ, Orishimo KF, Pappas E, Hagins M.
Am J Sports Med. 2014 May;42(5):1089-95. doi: 10.1177/0363546514524525. Epub 2014 Mar 4.
PMID: 24595401 [PubMed - in process] :

BACKGROUND:

Fatigue is strongly linked to an increased risk of injuries, including anterior cruciate ligament (ACL) ruptures. Part 1 of this study identified differences in the biomechanics of landing from a jump between dancers and team athletes, particularly female athletes, which may explain the epidemiological differences in ACL injuries between dancers and team athletes and the lack of a sex disparity within dancers. However, it is not known if these biomechanical variables change differently between team athletes and dancers in the face of fatigue. PURPOSE/ HYPOTHESIS: The purpose of this study was to compare dancers' and team athletes' resistance to fatigue and its effect on the biomechanics of single-legged drop landings. The primary hypotheses were that dancers may be more resistant than team athletes to the onset of fatigue and/or may have different biomechanical responses than athletes in landing tasks once fatigue has been achieved.

CONCLUSION:

Dancers took significantly longer to reach fatigue than team athletes. Female athletes consistently exhibited landing patterns associated with a risk for ACL injuries when compared with the other 3 groups. Fatigue changed landing mechanics similarly in both dancers and athletes, such that all groups landed with worse alignment after being fatigued.

CLINICAL RELEVANCE:

Dancers are more resistant to lower extremity fatigue than athletes, and this may partially explain the lower incidence of ACL injuries in both male and female dancers compared to team athletes. The extensive training in landing technique and daily practice that dancers undergo from a young age may be responsible for the higher levels of endurance.

Geil danke Michie!

Fazit:

• Aufs Alignment/Beinachse achten beim Training, vor allem gegen Ende des Trainings noch mehr verstärkt.
• Mehr Coretraining einbauen für die Stabilität!
• Frauen noch verstärkter darauf achten, dass Knie nicht nach innen wandern beim Absprung und beim Landen. 

 

Die Studie ist nicht auf Parkour ausgelegt und deswegen nicht direkt übertragbar. Aber Coretraining und Beinachsenperfektion kann so stehen bleiben meiner Meinung nach
