why dancers have low ACL injury rates

Kim Shore-Bechard linked to this important video. Must watch.

NYU Langone’s Harkness Center for Dance Injuries (HCDI) performed a study on the biomechanics of jump landing, comparing athletes and dancers to learn more about the incidence of anterior cruciate ligament (ACL) injuries in both groups.

From this study, HCDI has been able to identify training methods that dancers implement early on that can be useful to athletes who experience a higher rate of ACL injuries than dancers.

Thanks for the video! It just makes me more sure that I’ve already found out in practice, dancers are extremely efficient with jumping and reduce the impact more professionally (and they keep lines and body tight in places which are not primary for absorption).

It’s probably the landing surface that is responsible for differences in landings, tougher surface teach you to treat landing with more respect/attention from the start, especially when you have to maintain the form and extensions.. tracers take off and landing is also a bit different from classically-trained gymnasts, they don’t count on re-bound that much.. I have been thinking and making some notes to myself about it recently, in terms of take-offs and explosiveness from the platform in diving, and discovered a ‘wheel’ – ballet dancers are amazingly efficient in terms of explosive jumps and proper technique for the take off (more calf, less squat, more extension, more effective ankle) and ‘Bam!’ this video where people talk about similar things for landings..

It should be noted that dancers, versus gymnasts, are not landing from tremendous height &/or rotating at the same time. If gymnasts were only required to leap & jump, their rate of ACL tear, like dancers, would be much lower.
I think comparing dancers’ landings to gymnasts’ landings is somewhat apples to oranges.

True, generally. Provided coaches take proper time and caution constructing good habits on take offs and landings. But it should be stressed for less experienced coaches or amateur athletes – develop proper jump, alignment, points to consider (like tight abs), etc. – don’t rush.
This video is good that it stresses it out one more time (at least to stir thinking about it) and raises a topic where some useful information can be shared. At least, for me.. But again, not a professional interest, only personal.

Plus, some of ballet jumps are quite intense – pirouetting after splits (all in air) and landing on one leg could cause torn anything without the proper technique.
