ABSTRACT
Introduction: As it is in a number of sports, in CrossFit, nutrition is critical for providing training load and faster re co-
very processes.
Applied methodology and methods: We surveyed 12 men and 13 women training CrossFit unprofessionally. e average
age of the men was 31.5 years, average sports experience of 3.6 years, and performing an average of 3.5 workouts per
week. e average age of the women was 28.9 years, average sports experience of 2.7 years, and performing an average
of 3.6 workouts per week.
e subjects completed a diet-assessment questionnaire developed by us, which included questions about age, training
experience, number of training sessions per week, height and weight and 28 questions about their weekly consumption
of basic food products. Basic metabolite rate (BMR) was calculated according to the Harris-Benedict formulas. Daily
energy intake (DEI) and daily energy needs (DEN) was calculated от BMR, multiplied by physical activity coecient
dependent on the number of weekly training sessions.
Results: We estimated relative DEN of 34.0 kcal/kg BW and DEI of 37.4 kcal/kg of men. e DEN of women was 36.6
kcal/kg BW and the DEI was 38.8 kcal/kg BW. With regard to the intake of proteins, fats and carbohydrates, there are
no signicant dierences between the two groups under study. Intake of fats of animal origin was slightly higher in males
than those in the women.
Conclusions: In the study groups, we see a good ration between DEN and DEI and a high relative protein intake and a
lower intake of fat, characteristic more about power sports.
Key words: CrossFit, nutrition, basic macronutrients, Daily protein intake
INTRODUCTION
In the last few years, CrossFit has been considered
one of the fastest developing sports based on high
functional load (Kozub, 2013; Claudino et al, 2018).
Like in most sports, proper diet in CrossFit is cru-
cial both for the energy supply of the training load
and for the fast recovery (Crosst inc., 2014; Sousa
et al, 2014).
Athletes’ daily intake of carbohydrates, proteins,
and fats is mainly determined by the intensity of
the training load, its content, and the repetitiveness
of the weekly cycle. Additional indexes are gender,
age, and athletes’ qualication (Mcardle et al, 1996;
Kreider et al, 2004).
e healthy diet recommendations for people not
engaged in sport include about 45-55% carbo-
hydrates, 15-20% proteins, and about 20-25% fat
(mostly unsaturated) in their daily energy intake.
is also determines the weight values: carbohy-
drates (3-5 g/kg), proteins (0,8-1,0 g/kg), and fats
(0,5-1,5 g/kg) (Kreider et al, 2004).
CrossFit dietitians recommend that the proteins
should ensure about 30% of the daily energy in-
take (1.5 - 2.2 g/kg) (Crosst inc., 2014) in order to
maintain muscle growth and recovery aer a phy-
si cal load (Phillips, 2006), (Kim et al, 2018). eir
exact quantity is determined by athletes’ ac ti vity
and training experience, as well as by the intensity
of the training load (Crosst inc., 2014).
Carbohydrates should ensure about 40% of the dai-
ly calorie intake (Crosst inc., 2014). It is recom-
mended that they should mostly be of low to mod-
erate glycemic index (Crosst inc., 2014; Escobar
et al, 2016).
Fats should be about 30% of the daily energy intake.
It is recommended that monounsaturated fatty ac-
ids should be prevailing (Crosst inc., 2014). us,
one can maintain the energy balance and the in ner
muscle levels of triglycerides, as well as can ensure
the presence of essential fatty acids (Kreider et al,
2014).
e aim of this study was to prove that the actu-
al intake of proteins, carbohydrates and fats is an
important factor for the energy supply of athletes
practicing CrossFit.
Tasks
1. An inquiry among people (male and female)
practicing CrossFit about their diet.

2. Evaluation of the adequacy of CrossFit men
and women’s diet.
3. Establishment of the di erences between men
and women as regards the proportions of the
nutrients in their diet.
METHODS
e research was done among 12 men and 13 wom-
en who practice CrossFit professionally at a special-
ized gym in the city of So a. e men’s mean age
was 31.5 years, their mean training experience was
3.6 years with an average of 3.5 training sessions a
week. e women’s mean age was 28.9 years, their
mean training experience was 2.7 years with an
ave rage of 3.6 training sessions a week.
e participants lled in a diet questionnaire, de-
sig ned by us, which had been used in other surveys
with di erent subjects (Kolimechkov et al, 2016;
Pet rov, 2017; Zaykova, 2017; Zaykova, Petrov,
2017). e test included questions about the ath-
letes’ age, sports experience, number of training
sessions per week, stature, weight and 28 questions
about the weekly intake of the main nutrients. On
the basis of the answers we calculated the daily in-
take of pro teins, carbohydrates, and fats (kg/body
weight) and their relative share in the energy supply
in the daily energy intake (DEI). e relative share
of the pro teins and fats gained from foods with an-
imal origin was also established.
e basic metabolism was calculated with Har-
ris-Benedict’s formulas, and the daily energy needs
(DEN) were calculated from the basic metabolism
multiplied by a coe cient for physical activity on
the basis of the number of training sessions per
week (Harris, Benedict, 1999).
As a reference source about the ingredients and en-
ergy content of the main food products, included in
the questionnaire, we used National Nutrient Da -
ta base for Standard Reference Release 28, United
Sta tes Department of Agriculture, Agricultural Re-
sea rch Service.
e results were statistically processed with the he-
lp of IBM SPSS 19. In order to evaluate the di e-
rences in the mean values we used Student’s test for
independent samples. e mean values in the texts
are presented with the standard deviation (SD), and
in the gures – with the standard error (SE).
RESULTS
As regards DEN and DEP, there were no statistical-
ly signi cant di erences between men and wom-
en. Fi gure 1 presents the results obtained for DEN
and DEI for all researched individuals. ere was
a higher DEI among those engaged in sport which
could be explained with the high energy ex pen di-
ture characteristic of CrossFit. ere was no sta tis-
tically signi cant di erence between DEN and DEI.

Figure 2 presents the researched individuals’ daily
intake of proteins, fats and carbohydrates (kg/body
weight). ere was no statistically signi cant di er-
ence in the relative share of the nutrient intake be-
tween the men and the women. e protein intake
was on the lower recommended border for those
who practice CrossFit (Cross t inc., 2014).

Figure 3 presents the relative share of the proteins,
fats, and carbohydrates in the daily energy intake of
the subjects. ere was a signi cantly higher intake
of carbohydrates (54.8%) than the recommended
40% in CrossFit. As regards the energy supplied by
proteins, there was a signi cantly lower share (17.7
%) than that recommended in CrossFit (30%). e
fats ensured 27.5% of the energy intake which is
very close to the recommended 30% (Cross t inc.,
2014).
Figure 3. Relative share of the proteins, fats and carbohydrates in the daily energy intake
e proteins gained from foods with animal ori-
gin were 53.7 ± 8.3%. e fats with animal origin
were prevailing 68.1 ± 13.5%. e men reported
to have consumed a little greater quantity of fats
with animal origin than the women which could be
explained with the high intake of meat, sh, eggs,
milk and dairy products. ere was no statistically
signi cant di erence in the intake of protein with
animal origin between the researched men and
women.

Figure 4 presents the researched individuals’ rela-
tive daily intake of proteins. Only the subjects N6
(2.4 g/kg) and N20 (2.6 g/kg) were over the upper
border of the recommended intake of proteins in
CrossFit. e subjects N7, N13, and N23 consumed
proteins on the level of the upper recommended
border. Among 11 of the researched individuals – 5
women and 6 men, there was protein intake low-
er than the lowest recommended border (Cross t
inc., 2014).
Figure 4. Relative daily intake of proteins. e line shows the lowest recommended border
of the relative protein intake – 1.5 g/kg.
DISCUSSION
e lack of statistically signi cant di erence be-
tween DEN and DEI among the researched indi-
viduals shows a satisfactory relevance between the
energy needs and the energy intake.
On the one hand, there is an average protein intake
on the lower recommended border in CrossFit (1.6
g/kg). On the other hand, 40% of the researched in-
dividuals consume quantities of protein below this
border with an average intake of 1.1 ± 0.13 g/kg.
ese athletes should increase the intake of pro-
teins to over 1.5 g/kg which would lead to reaching
the relative share of the proteins in the total energy
intake of 30%, recommended for those practicing
CrossFit.
