How to Increase Turnout Safely


            "Turn-out is something a dancer does, not necessarily something he has." - Anne Woolliams

            Since turnout is an integral part of ballet technique, it is important for dancers to learn how to turn out and maintain it in ways that are healthy for their bodies. 

            The hip is the only ball and socket joint in the leg.  This type of joint allows for movement in all directions and provides the ability to rotate the leg outwardly, or turn out.  The amount of turnout a dancer has is largely pre-determined by the angle and length of the femoral neck, the facing of the hip sockets and the flexibility of the muscles of the hip.


            The hip joint is formed where the head of the femur, or thighbone, fits into the socket, or acetabulum of the pelvis.  The neck of the femur forms an angle, between the femoral head and the long shaft of the femur that allows the femur and pelvis to connect.  This average angle measurement is about 15°.  When the angle is less than 15°, the legs will naturally rotate outward, but if it measures more than 15°, the legs will naturally rotate inward. (2)

            Outward rotation also occurs naturally if the hip sockets, or acetabula, face sideways rather than diagonally forward.

            Those with a longer femoral neck enjoy a greater range of motion at the hip joint.  However, a shorter femoral neck limits the range of motion because the femur comes in contact with the outer rim of the pelvis.

            The muscles surrounding the hip include those that flex the thigh, extend the thigh, inwardly rotate, outwardly rotate, adduct (pull the leg toward the midline of the body) and abduct (pull the leg away from the midline of the body).

            Unlike the previously mentioned bony structures, muscles can be changed through exercise.  Ballet dancers often ask which muscles they should strengthen and/or stretch to improve their turnout.  The answer is a simple one – all of them.  All of the muscles surrounding the hip perform more than one function.  There is no muscle that acts only as an outward rotator.  Moreover, it is important to remember that ballet dancers perform exercises that always require an additional action to turning out.  A grand battement to the front requires flexion, a grand battement to the back requires extension, beats require adduction and dégagés require abduction.  When these exercises are being performed, the muscles of the opposite hip must also work as stabilizers to keep the dancer’s standing leg steady, turned-out and lifted.

            By strengthening and stretching all of the hip muscles in a conditioning program, the dancer will increase the range of motion at the hip joint.  This greater range of motion will allow for increased turnout, and the strength training will provide the dancer with the ability to maintain that rotation during exercises.

In Dance Kinesiology, Sally Sevey Fitt provides a hip conditioning program which includes single leg lifts to 45 degrees  while lying on the back and the stomach, stretching the hamstrings while lying on the back and holding the legs in second, stretching the quadriceps, the seated frog press, the yoga sit stretch and the lying knee press. The lying knee press involves lying on the back with the feet hip distance apart. The knees are allowed to fall in and are then actively pressed together for 20 seconds. This action is followed by allowing the lower body to twist to the right while the left leg is rotated inward to stretch the outward rotators and is then repeated for the right leg. (1)

            A word of caution….A stretch that dancers often use to increase turnout is known as the frog and is done while lying on the stomach.  This stretch needs to be AVOIDED!  The position of the legs places unnecessary stress on the ligaments of the knee and can do more harm than good.

AVOID THE FROG!!!
            By using a supplemental conditioning program to strengthen and stretch the muscles surrounding the hip, dancers will establish a greater range of motion and develop the strength necessary to hold positions.  Exercises done in class specifically target the outward rotators while supplemental exercises will keep the hip healthy and prevent dangerous muscular imbalances from occurring and causing injuries.

Periodization Training in Dance?


“Dancers are the athletes of God.” – Albert Einstein

            Studies done on dancers have found that their overall fitness levels are equal to those of their sedentary peers.  Since dance classes are filled with short intervals of movement followed by rest periods, they do little to train dancers aerobically.  Heart rate and oxygen levels required during rehearsals and performances are higher than the levels ever achieved in dance classes.  These findings indicate that the current levels of training do not adequately prepare dancers for the levels of fitness expected during a performance.

            A study published in the January 2010, issue of The Journal of Dance Medicine and Science found that low levels of aerobic fitness were associated with higher numbers of injuries, and 85% of the professional ballet dancers that were studied were injured during a 12-month period.

            All of these findings indicate that dancers can benefit from a periodized training approach to dance.

            Periodization is a program design that has been used in sports and strength training since it was introduced in the 1960’s by Russian physiologist, Leo Matveyev.  The goals of periodized training are to improve overall fitness; to gradually prepare the body; to strengthen the body and maintain muscular strength, flexibility and skill levels throughout the competitive season; and to avoid overtraining syndrome.  Overtraining is when an excessive amount of training and/or frequent training sessions result in fatigue.  The fatigue leads to overtraining syndrome, which is a decline in performance due to overwork.  After overtraining occurs and performance levels decrease, it is harder for the body to return to the previous peak level of fitness.

            Periodization divides the year or semester into three different phases, or mesocycles, that consist of the preparation phase, the building and strengthening phase and the performance phase.

         
         The preparation phase comes at the beginning of the semester when the dancers are returning from a vacation and need to gradually ease their bodies back into class.  Exercises during this period should be of a low intensity.  During the building phase, dancers should work on increasing strength, developing skills and increasing intensity.  At the end of this phase, the dancers should be at their peak strength and power levels.  The goal of the performance phase is to maintain these peak levels of strength and power without overtaxing the muscles.

            It is also important to work in breaks between each phase to allow the body to rest.  These rest periods allow for cellular and neural recovery and a mental break from activity.  The rest periods are imperative to avoid overtraining.

            Next week’s post will explore how to put these phases to practical use in the dance studio and how to improve dancer fitness.
