5 Strengthening Exercises for Dancers

Overuse injuries are commonly found in dancers due to their intense training regimes. Nearly 60 to 90% of dancers experience an injury or multiple injuries during their careers (Steinberg, Siev-Ner, Peleg, et al., 2013). These injuries include chrondromalacia patella (“runner’s knee”), Achilles tendinopathy, and metatarsal (foot) fractures. Some major causes of injury may be due to anatomic structure, genetics, training regime, improper technique, floor surfaces, age, body mass index, muscle imbalance, nutrition, and menstrual function (Steinberg et al., 2013).

Dance typically includes being on the toes and forefoot in a extreme plantar flexion position, known as “en pointe.” Individuals with poor balance and landing techniques will experience higher ground reaction forces which may subsequently strain the back, knees, and ankles. Incorrect form in many non-professional dancers entail a valgus knee position (knees caved inwards) and hip adduction. Conversely, mature, experienced dancers are able to rely on stronger hip and knee joint muscles to stabilize themselves during landing from jumps. Young dancers also experience lower back pain. Causative factors include high preseason training intensity, history of low back pain, low body weight, scoliosis, and stress fracture in the pars articularis of the spine (Steinberg et al., 2013).

Studies have recommended minimal exposure for young dancers to overload exercises, especially those involving the spine and caution with extensive stretching exercises (Steinberg et al., 2013).

Prevention

Here are a few essential tips to reduce the risk of injury:

  • Wear proper footwear and clothing
  • Drink fluids regularly
  • Do not dance through pain as it will exacerbate the damage
  • Practice correct dance technique 
  • Take adequate breaks during and between dance sessions
  • Ensure proper warm-up and cool-down (approximately 5-10 minutes)
  • Use preventative taping and/or braces if necessary

Strengthening

1) Woodchops – hold a light dumbbell or single cable in the highest pulley position with both hands and bring the weight downwards diagonally to the side of the leg opposite to the starting position. Remember to keep a flat back and tight core through out the motion. Repeat 8 to 12 reps on each side.
2) Lateral Step Downs – stand beside a step or a box, then place one foot on the step. Lift the other leg upwards by bending the knee to 90 degrees. Then bring the foot back down to the ground. Repeat 8 to 12 reps before switching sides. 
3) Core Stability – place your stomach onto a ball and keep the spine in a neutral position. Keep the inner core muscles engaged and reach one arm up in front with the opposite leg extended back. Hold for 3 to 5 seconds before switching sides. Repeat 10 times on each side.
4) Superman Deadlifts – hold a light dumbbell to the same side as the leg that will be extended back on. With a nice tall posture, engage the core and bend forward at the hips while you extend the leg back and reach forward with the opposite arm. Repeat 10 times on each side.
5) Squat Jumps – start with a tall posture, engage the core muscles by drawing the lower ab muscles inward toward the spine. Avoid arching the low back, with arms in a ready position, do a one-legged squat with the body weight equally distributed over the foot. Lower the body downwards by bending at the knees, then jump straight back upwards by engaging your glute and thigh muscles. Repeat 10 to 15 times for 3 sets.

Building a Stronger Core to Prevent Low Back Pain

Up to 80% of individuals will experience some lower back pain at least once in their lifetime. Lower back pain (LBP) results in high costs and places a burden on society. These costs include diagnostic, treatment, and indirect costs associated with work disability. A number of conditions can lead to low back pain such as infections, tumours, fractures or dislocations of the spine. However, lifting heavy loads is generally thought to be a key predictor of LBP. An important element in prevention of LBP is to correctly stabilize the trunk during lifting by pre-activating the abdominal wall muscles. By doing so, the spine will increase in stiffness to reduce the effect of undesired spinal perturbations. Exercises aimed at bracing the abdominal muscles may reduce the risk of LBP.

There are two ways of stabilizing the abdominal muscles: an abdominal hollow or abdominal brace. An abdominal hollow begins by drawing in the lower abdomen (transversus abdominus) while maintaining relaxation of the other surrounding abdominal muscles such as the obliques. At the same time, small muscles of the lower back (close to the spine) such as the multifidus are contracted while the larger back muscles are relaxed. With contraction of the lower abdomen and small back muscles, intra-abdominal pressure is increased and the fascia surrounding the spine increases in tension. Combined, these contribute to provide intersegmental stability.

An abdominal brace is performed by activating all of the abdominal and lower back muscles, rather than specific muscle recruitment. By tensing the entire trunk without drawing the muscles in or pushing them out, global activation of the ab and back muscles may provide increased stability in all directions in various movement patterns.

Both the abdominal hollow and brace can help increase the stiffness of the spine to minimize lower back pain. The use of either one will depend on the desired movement pattern and the goals of the individuals in stabilizing their core. Strengthening the core muscles is also essential in reducing the amount of loading on the lower back muscles. Watch these videos below:
