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.

Effects of Energy Deficiency on Performance

What is the “Relative Energy Deficiency in Sport (RED-S) Syndrome?”

The RED-S syndrome refers to impaired physiological functioning caused by relative energy deficiency and may result in impairments in menstrual function, metabolic rate, bone health, immunity, immunity, or cardiovascular health.
Energy availability (EA) is calculated as energy intake (EI) minus the energy cost of exercise (EE) relative to fat-free mass (FFM). In healthy adults, an energy balance is a value of 45 kcal/kg FFM/day.
Low energy availability is where an individual’s dietary energy intake is insuffient to support the energy expenditure required for health and daily living. It may occur in individuals who are required to diet to enhance performance, are pressured to lose weight, go through frequent weight cycling, overtrain, have recurrent and non-healing injuries, or strict regulations.

What happens if I have low energy?

As seen in the figure above, having low energy availability for your body can result in a number of negative consequences on your athletic performance. From decreased muscle strength to increased injury risk, athletes must be aware of the balance between their dietary energy intake and daily energy expenditure when exercising.  Signs of fatigue, irritability, depression, or weakness should be taken note of and addressed immediately.
Low energy availability may be linked to menstrual dysfunction in females or negatively impact bone health in both females and males. A lower bone mineral density may increase the risk of stress fractures which can have serious long-term consequences.


Treatment Strategies:

For individuals who have low energy availability, treatment involves increasing your energy intake and reduce exercise intensity or frequency. Attempt in implement an eating plan that increases current energy intake by approximately 300 to 600 kcal per day. To optimize bone health, include high-impact loading and resistance training at least 2 to 3 days per week. Intake of calcium and vitamin D are especially important for bone health. Having a food diary and/or exercise log is helpful in tracking your meals as well as exercise intensities to estimate what your daily energy availability is.

3 Key Exercises to Improve Balance

Why is it important to include balance training in your regular exercise program?


Balance is needed for just about everything you do on a daily basis from carrying groceries to putting on your shoes. Balance training involves strengthening exercises that target your entire body, especially the core. This not only reduces the risk of injury, but may improve motor coordination (Oliveira et al., 2017). At least 3 days of balance training per week is recommended for inactive and active older adults (> 65 yr). Activities such as pilates, yoga, tai chi, dance, or brisk walking are suitable for improving one’s balance. Implements such as bosu balls, balance boards, or foam pads can be used to add variety to your exercises. 

Try the Following Exercises Below:

1) Step-ups

a.     Stand in front of a box with a tall posture
b.     Step up with one leg, then bring the other leg up so that both feet are on the box
c.      Step down one leg at a time and repeat 10 times for each leg
d.     Increase the difficulty by using a taller box or increase your step up pace

2)  One Legged Squat

a.     Stand with a tall posture
b.     Bend your right knee and lift your right foot off the floor
c.      Keep your chest upright and arms extended to the front, slowly lower your body to the floor by pushing your hips back and down
d.     Slowly push up to the starting position and switch feet
e.     Remember to keep your knee in line with your second toe as you squat
f.      Repeat 10 times on each leg
3)  Single Leg Dead Lift

a.     Stand on your right foot, enagage the core, and slowly bend forward at the hips
b.     Reach towards the floor with the left hand and lift the left leg straight behind you
c.       Hold for 1-2 seconds and squeeze your butt muscles as your return to the starting position
d.     Switch sides and repeat 10 times on each leg
e.     Optionally: hold a light dumbbell in one hand as you reach toward the floor
