This study compared anthropometric variables, somatotypes,
and aerobic capacity between three groups of dancers: classical
ballet dancers (M 33, F 56), contemporary dancers (M 28, F
109), and dancesport dancers (M 30, F 30). The assumption
was that different functional requirements should produce differences in the anthropometric and aerobic capacity variables
among the three groups. Anthropometric data for body mass
index (BMI) and somatotypes were measured. Body fat percentage was measured by dual-energy x-ray absorptiometry.
Maximal oxygen consumption and aerobic power were measured during an incremental treadmill test until exhaustion.
Dancesport athletes were taller compared with same gender
contemporary dancers (p<0.05). Female ballet dancers had a
lower body mass and BMI compared with their contemporary
dance and dancesport equivalents (p<0.001). There was significant difference between dance styles in endomorphy (F2,221 =
8.773, p<0.001) and mesomorphy (F2,221 = 21.458, p<0.001)
scores. Dancesport dancers had significantly greater VO2max
values (p<0.01). It was concluded that female contemporary
dancers are generally more muscular than their ballet counterparts, while dancesport dancers are taller and heavier, less
muscular, with slightly greater adioposity compared to the classical ballet dancers. Ballet dancers had the lowest body fat percentage, weight, and BMI values. Dancesport dancers had
greater aerobic capacity than the ballet dancers. Based on this
study, we conclude that dancers in these three styles differ in
some aspects of anthropometric variables, somatotypes, and
aerobic capacity, but we cannot say is it because of the training
or selection or both. Med Probl Perform Art 2013; 28(4):207–211.

ancers face the difficult task of combining the aesthetic and physical components of their performance. They have been referred as “performing”23 and or
“aesthetic”35 athletes who remain subject to the same
unyielding physical laws as in other athletes.2 Dance training is a long process of physical, intellectual, and psychological preparation through physical exercise, often beginning in childhood and continuing until retirement.1

For optimal performance, dancers must be experts in
the aesthetic and technical sides of their art, psychologically prepared to handle the stress of critical situations,
and free from injury. They must also be physically fit.24 It
has been suggested that functional adaptation due to different training regimens may be responsible for the determination of some anthropometric15 and physiological32
changes. The number of hours per day and the days per
week that a specific physical activity is performed may
result in systematic changes in body composition.4 Hamilton,19 on the other hand, has said that “it is unclear
whether ballet selects the perfect body, creates it, or both.”
To our best of knowledge, there is no study done that
has compared anthropometric variables, somatotypes, and
aerobic capacity between classical ballet dancers, contemporary dancers, and dancesport athletes. Dancesport is
defined as partner dancing between a man and woman
combining as a couple. It has developed from ballroom
dances performed by couples. Currently recognized disciplines in international style dancesport are standard
dances, Latin American dances, and “ten dance” disciplines. Contemporary dance emerged at the beginning of
the 20th century as a breakaway from the rigid constraints
of classical ballet, which itself started as a performance art
in the French courts in the 16th and 17th century.2
A previous study has found no difference in VO2max
between ballet, contemporary, jazz, and character dance
students.13 Based on previous research2,25 that reported
VO2max values, we can assume that dancesport athletes
have higher aerobic capacity than ballet and contemporary
dancers. However, successful ballet dancers were taller and
thinner than modern dancers, although these differences
were not significant.16 The majority of previous studies
have focused on dancers in one specific dance style, such as
ballet, contemporary, or dancesport. It has been suggested
that ballet, contemporary, and dancesport dancers performance would benefit from a good aerobic capacity,1,22,25
and that performance of ballet and contemporary dancers
benefits from physiological capabilities such as muscular
strength and power.7,22 Little published data exist on
dancers’ somatotypes,16 but anthropometrical parameters
such as height and weight are well studied.2,6,12,25,28 It has
been found that body composition is influencing dance
performance.2 Many authors have been concerned about
the low body fat percentage of female ballet dancers,20,31 as
it can increase the risk of injury and delay healing.30
Just as the term sport covers a wide variety of different
disciplines, dance is an umbrella term that includes diverse

genres. Therefore, data obtained from one dance style may
not be applicable to other genres. Different dance styles
have different training and performance regimes. Auditions into dance schools and companies often involve
selecting dancers with specific anthropometric parameters.
Therefore, the purpose of the present study was to compare anthropometric variables, such as body weight,
height, percent body fat, somatotype, and aerobic capacity,
among three different groups of dancers: classical ballet,
contemporary dance, and dancesport. It was hypothesed
that dancesport athletes would have higher aerobic capacity indicators compared to the other two dance genres. In
addition, ballet dancers are more mesomorphic, with
lower body fat percentage compared to the dancesport and
contemporary dancers.
METHODS
Participants
Two hundred eighty-six dancers from the dance genres
took part in the study: 89 ballet dancers (male 33, female
56), 137 contemporary dancers (M 28, F 109), and 60
dancesport dancers (M 30, F 30). Ballet and contemporary
dancers were professionals. All dancesport athletes were
dancing couples who are competing at the international
level. Anthropometric measurements (height, weight, and
BMI) were taken on all the participants. Aerobic capacity
(VO2max) was measured in 40 ballet dancers (M 17, F 23), 19
contemporary dancers (M 7, F 12), and 60 dancesport
dancers (M 30, F 30). Body fat percentage and somatotype
characteristics were determined on 49 ballet dancers (M
16, F 33), 118 contemporary dancers (M 21, F 97) and 60
dancesport dancers (M 30, F 30).
Participants originated from Eastern Europe and the
UK. Dancesport athletes were among the top 6% of the athletes listed in the world rankings.14 The couples had been
dancing together for the 3.9±2.8 yrs. Average training experience for dancesport athletes was 14.9±5.1 yrs, and they
currently trained 11.9±6.2 hrs/wk. Dancesport participants
reported that they practiced manly dancesport-specific
training but also made physical preparation for the season
(jogging, stretching, etc). Ballet and contemporary dance
participants trained 38 hrs/wk, 6 days a week. There was
no organized cross training in all three dance styles.
All participants were healthy and free of injury. All participants signed an informed consent prior to testing. This study
was approved by the Medical Ethics Committees of the University of Tartu and the University of Wolverhampton.
Anthropometry, Body Mass Index, Percent Body
Fat, and Somatotypes
Body height (Martin metal anthropometer, GPM SilberHegner, Zürich, Switz.) and body mass (A&D Instruments,
Abingdon, UK) of the participants were measured to the
nearest 0.1 cm and 0.05 kg, respectively. The body mass
index (BMI) was calculated as weight/height2. Body compo208

sition was measured using dual-energy x-ray absorptiometry. Whole body scans were performed using a Lunar DPXIQ densitometer (Lunar Corp., Madison, WI) and analyzed
for body fat percentage.
All anthopometrical parameters for determination of
somatotypes were measured according to the protocol recommended by International Society for the Advancement
of Kinanthropometry (ISAK) by a person certified by
ISAK.27 Nine skinfolds, 13 girths, 8 lengths, and 11
breadth/lengths were measured on the right side of the
body using a Holtain skinfold caliper (Holtain, Crymmych, Grosswell, UK. Three series of anthropometric
measurements were taken for each site and the mean was
recorded. Three somatotypes components—endomorphy,
mesomorphy and ectomorphy—were calculated according
to the anthropometric somatotyping method.9
Incremental Treadmill Test
Maximal oxygen consumption was measured during an
incremental treadmill test until volitional exhaustion.
Heart rate (HR) was recorded at every 5 sec during the test
using Sporttester Polar 725X (Polar Electro, Oy Kempele,
Finland). The standardized 5-min warm up at 7 km/hr for
males and 5 km/hr for females was used before incremental test. The test started at 8 km/hr for males and 6 km/hr
for females and speed was increased by 1 km/hr after
every 2 min until exhaustion. Treadmill incline was 0%
throughout the incremental test. Breath-by-breath respiratory gas exchange variables were measured throughout the
test using a portable open-circuit spirometry system (MetaMax 3B, Cortex Biophysic GmbH, Leipzig, Germany. The
analyzer was calibrated before the test with gases of known
concentration according to the manufacturer’s guidelines.
All data were processed by using standard software (MetaSoft, Cortex Biophysic GmbH) and the system for heart
rate (HR) analysis.
Statistical Analysis
Data were assessed for normality, and a 2 × 3 factorial
analysis (gender × dance style) was used to test for differences; Scheffe and Tukey post-hoc tests were used for
between-style comparisons (SPSS 20.0 for Windows,
Chicago, IL) and Pearson product correlations to ascertain
relationships between specific variables. The level of significance was set at p<0.05.
RESULTS
Anthropometrical characteristics of the subjects are presented in Table 1. There were significant differences
between dance styles in height (f2,280 = 9.677, p<0.001), body
mass (f2,280 = 11.912, p<0.001), and BMI (f2,280 = 18.822,
p<0.001) values. Post hoc tests indicated that male and
female dancesport dancers were taller compared to same
gender contemporary dance participants (p<0.05). Female
contemporary dance and dancesport dancers had higher

dancers (p<0.001). Female contemporary dancers had
higher BMI values than female dancesport dancers
(p<0.05). There was a significant difference in age (p<0.05),

dancers had lower endomorphy values compared to
female ballet and contemporary dancers (p<0.001). Female
ballet dancers had lower mesomorphy values compared to
female contemporary (p<0.05) dancers. In contrast, female
ballet dancers had higher mesomorphy scores compared
to female dancesport participants. Male (p<0.05) and
female (p<0.001) contemporary dancers had higher mesomorphy values than same-gender dancesport dancers.
There was a significant difference between genders in
body fat percentage, endomorphy, and mesomorphy
values (p<0.001). There were no significant differences in
ectomorphy scores.
DISCUSSION
The aim of the present study was to assess the homogenity
of professional dancers for anthropometric variables and
aerobic capacity. Within the exercise science literature,
there have been very few studies that have compared the
different dance genres to ascertain whether there are uniform characteristics such as body shape and aeriobic fitness among the three dance genres classical ballet, contemporary dance, and dancesport. Within sport, it is well
established that different sports require participants to
have specific anthropometric and physical characteristics
to compete at an elite level.4,17 It has also been suggested

that functional adaptation due to different training regimens may be responsible for the determination of some
anthropometric changes.15 Height, body weight, body fat
percentage, and VO2max values of classical ballet dancers,
contemporary dancers, and dancesport dancers were similar to those reported in previous studies.5,6,10,21,25
Female ballet dancers had lowest body fat percentage,
body mass, and BMI compared with female contemporary
dance and dancesport dancers, confirming the genre’s
requirements for female dancers to be light, low body fat
content, and low body weight in order to perform the tasks
related to classical ballet.29 Female ballet dancers lower
body fat percentage, body mass, and BMI compared with
female contemporary and dancesport dancers may relate
to different aesthetic values of ballet, contemporary, and
dancesport dancers. The observed higher height of dancesport athletes compared to contemporary dancers may be
related to the fact that dancesport does not have lifts
within its choreography, which require the female dancer
to be lifted above the partner’s head where her weight
could become an issue. The choreography, especially with
standard dances, requires large movements and shapes,
especially in the upper body, which is enhanced by having
a taller frame and longer limbs. Standard dance is one of
three dancesport disciplines where five standard dances
(waltz, tango, Viennese waltz, slow foxtrot, and quickstep)
are performed. All standard dances demand wide movement and big shapes, and in dance hold, greater height
probably helps to achieve this.
There was significant difference in mesomorphic and
endomorphy scores between the three dance styles (Fig. 1).
Female danceport dancers are less mesomorphic and endomorphic than females of the other two dance styles, and
female contemporary dancers are more mesomorphic than
female ballet dancers. The reason for higher mesomorphy
scores for contemporary dancers may be because, unlike
most ballet dances, contemporary dance has less of a
gender divide within the choreographed movements34 and
the dancers often come from a multidisciplinary background (e.g., gymnastics).23

Medical Problems of Performing Artists
Previous research has reported the somatotypes for aesthetic sports like gymnastics and figure skating are as follows: figure skating, males 1.7–5.0–2.918 and females 3.4–
3.7–2.926; gymnastics, male 2.6–6.2–1.58 and females 2.6–
4.4–2.6.8 Compared to other aesthetic sports such as figure
skating and gymnastics, male dancers of all three genres
(ballet, contemporary and dancesport) were less mesomorphic than male gymnasts8 and figure skaters.18 Male contemporary dance and dancesport participants were more
ectomorphic compared to male figure skaters18 and gymnasts.8 Male ballet dancers were more ectomorphic compared to male gymnasts.8
Female figure skaters26 and gymnasts11 were more
mesomorphic compared to female dancesport and ballet
participants. Female contemporary dancers, on the other
hand, were more mesomorphic than female figure
skaters26 and gymnasts.11 Female dancers of all three
genres were more ectomorphic compared to female figure
skaters26 and gymnasts.11
It has been suggested that dancers would benefit from
aerobic training1 and a high anaerobic threshold to limit
the effects of fatigue, such as a decrease in balance, poise,
and coordination.3,25,33 The dancesport participants
recorded the highest relative oxygen uptake, while classical
ballet dancers demonstrated lower maximal oxygen
uptake than contemporary dancers.2 These differences
could be due to the variation in the physical demands of
dancing in the different genres.13,34 Classical ballet and
modern dance are noncompetitive, and dancers do not
need to strive against others during performance. Dancesport, in contrast, requires competing throughout the day
and to be recalled through a number of rounds before
reaching the final. This difference between the genres is
especially highlighted in the aerobic capcity of female
dancers, where the dancesport participants had significantly higher VO2max than the other two genres. This
could be due to the training and competitive requirements
of dancesport and especially standard dances, which
require the female dancers to match their male partners
stride for stride.
CONCLUSION
Classical ballet, contemporary dance, and dancesport
dancers differ by somatotype. Female contemporary
dancers are generally more muscular than their ballet
counterparts, while dancesport dancers are taller and
heavier, less muscular, and with slightly greater adioposity
than the classical ballet and contemporary dancers. Ballet
dancers had the lowest body fat percentage, weight, and
BMI values. Dancesport dancers had greater aerobic
capacity than ballet dancers. Based on the results of this
study, we can conclude that classical ballet dancers, contemporary dancers, and dancesport professionals differ in
some aspects of anthropometric variables, somatotype,
and aerobic capacity, but we cannot say if it is because of
the training, selection, or both.
