Our bones are important because they serve as the foundation on which we are built. Bone is living tissue that contains blood vessels; proteins, including collagen; and cells that are actively maintaining healthy bone. Bone also contains many minerals, the most important of which is calcium.

Building Strong Bones

We have the best chance of building our strongest bones when we are young — because the rate at which we form bone is higher than that of losing bone up until about the age of 30, when peak bone mass is reached. After peak bone mass is reached, we starting losing bone at a higher rate than we form it. The majority of the mass of our bones forms between the ages of 11 – 14 in girls and 13 – 17 in boys. The more bone mass you have by the time you reach peak bone mass, the less of a chance of you have of breaking your bones, especially later in life as bone loss occurs.

Bone Health And Your Diet

fuel-2741_640As dancers, we place a lot of stress on our bones. This stress can lead to damage of bone tissue. However, luckily our body is designed to repair itself, so bones maintain their healthy structure by containing cells that remove damaged bone and replace it with healthy bone, also known as bone turnover.

In order to achieve the highest bone mass possible and to ensure healthy bone turnover, it is important for our bones to have the right ingredients. Dancers need have enough nutritional intake based on activity level, adequate calcium, and adequate Vitamin D. Without these, a decrease in bone density can occur, making a dancer susceptible to fractures and stress fractures.

Dance is a form of exercise which uses energy. This energy needs to be replaced by consuming enough healthy carbohydrates and fats so that your body can continue to function normally. Having adequate fuel is especially important for girls to ensure normal, regular menstruation. The hormones that regulate menstruation directly affect bone mass. If a dancer does not consume enough calories and fats to adequately re-fuel the body, then the hormone balance gets thrown off – which can result in a decrease in bone density.

It is not unusual to experience irregular periods (meaning periods that do not come monthly) during the first year of menstruation. However, missing your periods for months at a time or getting your period too late, may also be a sign that you are not consuming enough calories. Genetics and other medical issues could also be playing a role in abnormal menstrual cycles or later onset of menstruation. It is best to consult a physician if you do miss your period for more than 2 months, especially if this occurs on a regular basis, or if you are 15 years old and have not gotten your period. Males are also susceptible to bone loss due to inadequate energy consumption. All dancers need to consume enough calories to re-fuel the body.

Bone Density

broccoli-952532_640The human body is designed to always have normal calcium levels – so if you do not consume enough calcium, it will take it from bone which again will lead to decreased bone density. The Institute of Medicine currently recommends consuming the amount of calcium based on age shown in Table 1 below. It is best not to exceed the amount of calcium shown at the upper limit column because this can increase the risk of forming kidney stones. It is best to get calcium from dietary sources such as dairy, almonds, broccoli, Brussels sprouts, and dark leafy greens, to name a few. Check your food labels and calculate how much calcium you get in a day. If you do not reach the level recommended in Table 1, then buy a supplement. Do not take more than 500mg at a time to maximize effective absorption.

Table 1: Institute of Medicine Daily Adequate Intake of Calcium

Age Calcium (mg/day) Calcium (mg/day) Upper Level Intake
4 – 8 1000 2500
9 – 18 1300 3000
19 – 50 1000 2500
51 – 70 1200 2000
> 70 1200 2000
Osteoporosis 1500 2500

Bone Health And Vitamin D

pill-316601_640In order for your body to absorb dietary calcium, you need to have an adequate amount of Vitamin D. The best source for Vitamin D is from the sun. Vitamin D is formed by cells in the skin layer. Sun exposure to form Vitamin D in the skin is inhibited by sunblock and decreased by clouds and pollution. Additionally, the darker the skin color, the longer daily exposure time to sun is needed for the cells in your skin layers to form adequate vitamin D. Generally speaking safe sun exposure (no sunblock for the time allotted as long as there is no risk of skin cancer by family or personal history of skin cancer) is best obtained between the hours of 10am – 3pm on the arms and legs for a minimum of 20 minutes per day depending on skin color and the latitude in which you live.

The further you are from the equator, the less Vitamin D is formed during winter months. It is difficult to adequately consume Vitamin D from foods fortified with Vitamin D. A few foods such as Cod Liver Oil, egg yolks, salmon, sardines, mackerel, and canned Tuna are natural sources of Vitamin D. One study found that more than 95% of dancers are deficient in Vitamin D. If you cannot get enough sun exposure, the Institute of Medicine recommends the supplementing Vitamin D at the levels based on age shown in Table 2 below. Your doctor may check a blood level and recommend a higher dosage of Vitamin D to boost your levels quickly. It is difficult to become toxic with Vitamin D supplementation. Follow your doctor’s advice.

Table 2: 2010 Institute of Medicine Daily Adequate Intake of Vitamin D

Age Vitamin D (IU)
0 – 1 600
1 – 70 600
> 70 800
Pregnancy 600

In summary, it is best to ensure adequate Vitamin D levels, calcium intake, and food intake to develop and maintain strong bones. The younger you begin, the better off you will be in the future.

The Joffrey Ballet opens its Bold Moves program Wednesday, February 10th at Chicago’s Auditorium Theatre with one world premiere and two audience favorites. The evening will feature live music from The Chicago Philharmonic, with Joffrey Music Director Scott Speck at the helm.

Jirí Kylián’s Forgotten Land is the opening piece, set for 12 dancers, with music by English composer Benjamin Britten. Last performed by the company in 2012, this well-received ballet was inspired by an Edvard Munch painting of women staring at the sea from the beach. The choreography does indeed evoke water, its many lifts and swirling motions resembling the ebb and flow of waves.

Preview of world premiere:

Another work for 12 dancers, Ashley Page’s world premiere, Tipping Point, is the next item on the program. This piece is centered around the music, Thomas Adès’ violin concerto Concentric Paths. An award-winning choreographer, Page has a strong background in ballet, but this abstract piece focuses on highlighting human behaviors that are illuminated by the shifting tensions of the score. Take a closer look at how Page came to work with Joffrey in this post on Art Intercepts.

RAkU is the final piece in the Bold Moves program, and it is a truly unique offering. First created for San Francisco Ballet in 2011, Yuri Possokhov’s contemporary story ballet is based on the burning of Kyoto’s Golden Pavilion. The choreographer commissioned a score by composer Shinji Eshima, and the music illuminates the love story beautifully. A stunning visual piece as well, RAkU fits nicely with the program’s theme, as it leaves quite an impression.


Bold Moves runs from February 10th through the 21st at Chicago’s Auditorium Theatre.

Dance Students: The Importance Of Good Character

by Lucy Vurusic Riner

There is a lot of talk that typically surrounds the plight of the millennial. Did their parents raise them to be self-sufficient? What sort of work ethic do they have? How do their values and morals play out in today’s workforce?

And, for me as a teacher, how do I impart my “Gen X wisdom” on them in dance class?

I wonder about this each day as I watch my students come into class. They really do toggle back and forth from being complete perfectionists and go-getters to being completely entitled and lazy. As a parent I wonder when their character will begin to take shape and how much influence their own parents have over the kinds of humans that are walking into my dance class each day. As an executive director of a dance company I wonder if I would hire more than a fraction of them upon graduating from college.

Attitude matters these days.

Teaching high school dancers (and I believe this extends well into college as well) is challenging in that most of our students are setting goals that are superficial; or what I like to call surface level. They read the syllabus or the rubric to see what they need to do to get the A or get cast in the role and then they simply do the bare minimum to make that happen. There is a preconceived notion that if you’ve done all the work, you now deserve the job. Period. The problem is that a lot of them can do the work. A lot of them can even do the work well; but there aren’t enough jobs for the amount of dancers we’re cranking out these days.

We need to teach them that doing the work is standard. It’s status quo. It’s the bare minimum expectation. It’s what happens after you’ve done part one that leaves an impression. It’s more than just bringing your skills and talents. Attitude, character and work ethic matter.

BDancewear Clothing Review

Regular-Dance-Shrug-Lycra-2T

Cotton Shrug

by Catherine L. Tully

The staff over at BDancewear asked if I would like to check out some of their merchandise and write something up for our readers.* When I agreed, they shipped me a nice box of goodies to try out, and I’d like to share some of my favorites with you. But first, I wanted to mention a little bit about the company itself, as I think some background is always nice…

One thing I found fascinating about this business is that they offer items in 200+ different colors. The ability to get a piece you like in a shade you love it pretty impressive. And the pieces are all made in the USA, which to me is another selling point. Add to that the fact that you are supporting a small business when purchasing from them, and it stacks up to be a pretty good deal overall. Especially since the items I sampled were very well made.

High-Waist Pants

High-Waist Pants

By far my favorite item in the package was the pair of high-waisted pants. I got the cotton ones, and they are excellent quality, lasting a very long time. I washed and dried them repeatedly, and since they are a bit on the long side (which I love, because I have long legs and my pants always shrink too much), they stood up to it just fine.

I’ve had many types of pants like this – all name brands – and these held up better than any other one to the wear/tear and wash cycle of a dancer. No splitting seams, no see-through spots, no loose elastic. I’m still wearing them, many months later. The only caveat is they are long, so shorter people may have an issue with the fit. They also make a high-waisted brief that is very comfortable.

I love shrugs, and the ones offered by BDancewear are no exception. Besides keeping my arms warm in a tank top or sleeveless leotard, they look pretty. I find these are one of those “optional” pieces, like a dance skirt, that makes you feel more like a dancer. Decorative/fun pieces. And again, the ability to dial in the fabric and color is a nice touch.

High-Low Skirt

High-Low Skirt

The company sells a full compliment of skirts as well, which can be a good choice for dance school students, or possibly instructor attire. I find the high-low skirts appealing, but there are a variety of choices, including angle skirts, circle skirts and longer skirts. To me these were better suited for the casual student, not as much geared toward the pre-professional or professional dancer. Studios with a color-coded system will find they can get any shade they need here.

In addition to the different colors available, BDancewear also offers a number of fabric choices, including lycra, velvet, cotton, mesh and more. They also stock sports bras, gloves, tank tops, briefs, leotards and other items.

Paris, Passion, And Pointe Shoes: Atlanta Ballet Presents Moulin Rouge®

By Rachel Hellwig

A tragic love triangle, the City of Lights, and the bohemian nightlife of the late nineteenth century—Atlanta Ballet brings Jorden Morris’ Moulin Rouge® – The Ballet back to the Cobb Energy Performing Arts Centre from February 5-13.

Created in 2009 for the 70th anniversary of Canada’s Royal Winnipeg Ballet, the production has since toured internationally, been adapted into a ballet film, and was re-staged on Atlanta Ballet in 2010.

Inspired by the iconic French nightclub depicted in the art of Henri de Toulouse-Lautrec, Moulin Rouge® blends ballet, Cancan, and tango to the music of composers such as Debussy, Offenbach, Shostakovich, Ravel, Johann Strauss Jr. and Astor Piazzolla, among others.

A fantasia of history and imagination, the ballet follows the stories of Nathalie–a laundress turned cabaret dancer, Charles Zidler–the sinister proprietor of the Moulin Rouge (“The Red Mill”),  Matthew–an aspiring painter, and, of course, Henri de Toulouse-Lautrec.

Atlanta Ballet veteran John Welker, now in his 21st season with the company, will portray Zidler and Toulouse-Lautrec. “What I really enjoy about these roles is that they are both based on real people,” he says. “They are not just a figment of the choreographer’s imagination. I love that, in some strange way, it makes you feel connected to that time period in Paris.”

Interestingly, the historic Toulouse-Lautrec would not likely have been able to dance. After breaking his legs as a youth, the bones did not heal properly and stopped growing. As a result, he was disproportionately short and struggled to walk, even with a cane.

Nonetheless, Morris wanted to bring him to life through dance. In an interview for Pittsburgh Ballet Theatre, he explained, “When choreographing the dance for Toulouse, I wanted the audience to see the amazing and beautiful things going on in his mind – which is translated through dance. It would have been easy to make his choreography twisted and deformed, but then we would never see the beauty behind what was in his mind.”

As Nathalie, the rags-to-riches Moulin Rouge star whose life is fatefully intertwined with Matthew, Nadia Mara returns to a role she first visited in Atlanta Ballet’s 2010 production. She delights in the character’s creative and dramatic possibilities. “Nathalie goes through so many emotions and transformations during the story,” she says. “It allows me to explore and work on my acting, which I always love. I can’t wait to show the audience this beautiful ballet!”

If you would like to be in the audience of Moulin Rouge®–The Ballet, tickets starting at $25 may be purchased here.

Aloha and Happy New Year !

I hope everyone had a wonderful holiday season, and you are back in full swing with your dance life. This month marks 4 years that I have been associated with 4dancers.org, and so I felt it was an appropriate time to comment – and to encourage you to keep “spreading the word” about dance medicine and science / aka Dance Wellness!

So, how did the Dance Wellness segment of 4dancers.org get here?

In the fall of 2011, Catherine Tully, editor of the site, approached me about writing an article about Dance Medicine and Science, to introduce that topic to the readership.  She and I had never met, or communicated, before that –i.e., it was a “cold contact”. I said “of course” and wrote that first post–which was supposed to be a one-time thing. But–the readership response was so positive that Catherine asked me to keep going…..and so our Dance Wellness segment became official.

Over time I started asking other colleagues in the field to also contribute, and things just kept growing.  This past year, we added our Dance Wellness Panel of experts–all long-time experienced professionals, each focusing on different aspects of dance medicine and science.

From a personal perspective, 4dancers.org has been one of the most fulfilling things that has ever happened in my professional dance life–and I say that coming from many years of very fulfilling experiences! Since the beginning of my work in the dance medicine field, 35 years ago, my #1 goal has always been to reach out to the thousands of dancers and teachers who don’t normally have a chance to access this kind of information. I was given different opportunities, in that respect, over the years–such as helping to form IADMS (International Association for Dance Medicine and Science), and starting Dance Wellness programs in university settings. And all of that was wonderful–but it still didn’t reach out on the “grassroots” level, which was my original goal.

4dancers.org, and Catherine Tully, changed all of that, and I will be eternally grateful both to her, and to you, the readership, for the opportunity I was given, and for the way you have embraced the information we have put out there for you, and “passed it on”!

Some of you reading this probably have been with 4dancers for a long time, maybe all of the past 4 years, but many of you may have not. So with this post, I am sharing our full list of dance wellness articles, so that if you missed any, you can read and catch up–and maybe learn one or two new things you didn’t know before…..and that’s the whole point, isn’t it?

Mahalo Nui Loa (thank you from the heart), and–
Pass it on!
