Stretching

Since I've discussed flexibility and turnout, it's probably worth talking about stretching in a little more detail. We all stretch regularly, whether it's making a concerted effort in class, or for 60 seconds between barre and centre work, it punctuates our days at regular intervals.



How much you get from stretching and how safely you are doing it will vary greatly depending on the type of stretching you do:


Static vs Dynamic
Dynamic stretching should be done before class - not static stretching. Unfortunately bad habits and bad teaching practices mean that static stretching still appears more often than anything else at the beginning of rehearsals. Dynamic stretching warms the muscle up by performing dance-like controlled movements. Static stretching (stretches held in place for 30 secs) is useful AFTER class or rehearsal, however this type of stretching fatigues the muscle so there is no point in doing it before you need to work, you'll end up getting hurt.

Ballistic
I don't advocate ballistic stretching due to the increased risk of injury. Ballistic stretching involves "bouncing" to push your stretch further, it's something I often see people new to stretching doing, or dancers trying to really push themselves to gain another couple of inches. The risk of hurting yourself is too high to balance out the relatively small gains on offer. Don't do it.

PNF
PNF (Proprioceptive Neuromuscular Facilitation) stretching is probably the most effective. It can produce significant long term gains in flexibility. PNF stretching requires you working with someone that knows what they're doing, otherwise you're going to waste your time and possibly hurt yourself. The basic premise of PNF is that to stretch your target muscle you perform a shortening contraction of the opposing muscle which is then followed by an isometric contraction of the target muscle. If you both know what you are doing PNF can be very effective in producing long-term gains.

Micro 

Research on micro-stretching is still in it's infancy, however so far it has been shown to be very effective. The idea is to only stretch your muscle to 30-40% of it's maximum and no more; going above this activates the nervous system, which in turn causes the muscle to contract. Regularly performing low intensity stretches for 60 seconds at a time, means the muscle becomes adaptable due to familiarity with the slightly increased stretch in the muscle fibres, resulting in a lengthening of the muscle as a whole.

Prolonged Stretches
Any stretch held for a long period of time is a bad idea. If you're doing it for more than a few minutes it's too long, if you go as far as 10 or 20 minutes you are straining and weakening your muscle and trauma sustained while doing this is liable to shorten and stiffen your muscle resulting in reduced flexibility.


The majority of dance injuries are sustained during flexibility exercises. Being sensible about how you stretch and when can make all the difference between a stiff, sore body, and a more mobile, adaptable one.

  1. Thanks for sharing this is a thoughtful, insightful piece...well done! As a former professional ballet dancer I second the idea that many retired dancers live with complicated feelings about their careers. Emotional strength is just as important, if not important, than physical strength.
