Abstract—The aim of the study was to compare the electromyographic (EMG) activity of the following muscles: cla-
vicular portion of pectoralis major, sternal portion of pectoralis major, long portion of triceps brachii, anterior deltoid,
posterior deltoid and latissimus dorsi during dynamic contractions between at horizontal bench press and barbell
pullover exercises. The sample comprised 12 males individuals experienced in resistance training. The volunteers made
three visits to the laboratory. The rst one consisted of 12 repetitions of the exercises for the electromyographic data
collection. The results showed a higher EMG activation of the pectoralis major and anterior deltoid muscles in the at
horizontal bench press in comparison with the barbell pullover. The triceps brachii and latissimus dorsi muscles were
more activated in the barbell pullover.

Introduction
The deltoid and pectoralis major muscles are the main muscles
of the glenohumeral joint, with an important function in daily
activities and in numerous sports skills (Santana, Vera-Garcia,
& McGill, 2007). Thus, it is important to include exercises to
increase the strength of the front and upper body, either for
aesthetic or therapeutic purposes. Also, such exercises can im-
prove sport performance in which the use of a sport equipment
is common, or upper body movements are required (Escamilla
& Andrews, 2009; Schick et al., 2010). In order to achieve im-
proved muscle performance, coaches often use the horizontal
bench press exercise (Sadri et al., 2011; Schick et al., 2010;
Tillaar & Ettema 2010), especially because of its effectiveness in
developing pectoral, triceps and anterior deltoid muscles (Kellis
& Baltzopoulos, 1998). However, other exercises and variations
of the horizontal bench press have been used to diversify trai-
ning. These changes usually include modications in the angle
of the equipment seat (Barnett, Kippers, & Turner, 1995; Glass,
& Armstrong, 1997; Trebs, Brandenburg, & Pitney, 2010), as

well as the use of other exercise equipments (McCaw & Friday,
1994; Trebs, Brandenburg, & Pitney, 2010), dumbbell exercises
(Uribe et al., 2010), dumbbell y exercises (Welsch, Bird, &
Mayhew, 2005), cables and pulleys (Clemons & Aron, 1997;
Sadri et al., 2011), and stable and unstable surfaces (Goodman
et al., 2008). These are exercise alternatives routinely prescribed
as a way to complement training.
Recently, a study performed by Marchetti et al. (2011)
demonstrated that the barbell pullover could also be used to
develop anterior and upper body muscles, the pectoralis major.
However, some other reports have shown that the exercise in
question also recruits latissimus dorsi bers, without signicant
differences between that musculatures and muscles portions of
the pectoralis major (Takara et al., 2005). When we analyzed the
biomechanics of the barbell pullover exercise compared with
other basic exercises used to improve the upper and front part
of the body, we observed a great difference between the move-
ments (Hall, 1999). However, even with these biomechanical
differences, barbell pullover exercise is still prescribed more
often to develop the musculatures of the upper and anterior parts
of the trunk, besides the back part of the trunk. Such choices
generate doubts about its true prescription, as they may result
in different responses, especially in the levels of electrical acti-
vation on the target muscles. In order to clarify these questions,
electromyography emerges as a reliable research tool, being
constantly employed for the analysis of physiological aspects of
muscle activity during exercise (De Luca et al, 2006; Escamilla
& Andrews, 2009).
Thus, the purpose of the study was to compare clavicular
portion of pectoralis major (CPPM), pectoralis major sternal
portion (PMSP), long portion of the triceps (LPTB), anterior
deltoide (AD), posterior deltoide (PD) and latissimus dorsi (LD)
muscles between horizontal bench press and barbell pullover
exercises with trained men.
Methods
Experimental approach to the problem
In order to investigate differences in EMG activation of
muscles for the horizontal bench press and the barbell pullover
exercises, two test sessions were established, in which partici-
pants were assigned to perform two exercises in a random order
in different sessions. The EMG signal was recorded during the
concentric and eccentric phases of each of 12 repetitions in order
to compare the levels of muscle activation in CPPM, PMSP,
LPTB, DA, DP and LD. Participants were selected according to
their experience in resistance training and in the target exercises.
Participants
Participants for this study consisted of 12 men (age: 24.50
±4.34 years, relative body fat: 13.63 ±1.94%, height: 176.0
±0.04 cm, body mass: 73.12 ±6.10 kg and, years of training:
3.58 ±2.90). To be included in the study, they could not have
bone nor muscle disorders that could compromise the execution
of movements. Also, they should have minimum experience
of 12 months in resistance training, and be familiar with the
horizontal bench press and the barbell pullover exercises. Par-
ticipants were instructed to refrain from any form of physical
activity for a period of 48 hours prior the tests. All volunteers
signed an Informed Consent Form, previously approved by
the Committee of Ethics and Research Involving Human
Subjects of the Central University of South of Minas (UNIS),
Minas Gerais State, Brazil (protocol 0068/2010). Volunteers
made three visits to the laboratory. The rst consisted in the
clarication of the likely questions regarding the research,
the signing of the Informed Consent Form, anthropometric
assessments, 1RM test, and explanation about the required
movements speed during the exercises. For the measurement
of the sample characteristics, data of height and weight were
collected using a scale with Welmy
®
stadiometer. The estimated
body fat percentage was measured through a Quantum BIA-II
®
tetra polar bioimpedance apparatus (RJL Systems, Inc. Clinton:
US-MI). Conmed
®
electrodes were used for the data collection.
The 1RM test followed the protocol NSCA (Earle & Baechle,
2004), in which participants progressively increased resistance
until 1RM was found. The movement speed was monitored via
a digital metronome, and pre-establishing 2 seconds for the
concentric phase, and 2 seconds for the eccentric one, totaling
4 seconds for a movement or 1 repetition. In the second and
third visits, participants performed the exercises presented in
a random order. Before testing, participants underwent the
EMG preparation protocol to avoid skin impedance, and then
performed a series of 20 repetitions as a specic warm up, with
a load set at 30% of their respective body mass. Then, a new
set of 12 repetitions at 70% 1RM was performed to record the
EMG signal. To perform BP we used a bar measuring 1.20 m
long, mass 6 kg, a HBP and Physicus
®
washers (Brazil). In the
initial execution of the movement, participants lay down on a
bench in a supine position, feet at on the ground, holding a
barbell with a pronated grip, and upper limb perpendicular to
the body. Grip distance was determined by the bi-acromial width
of each participant. The movement ended when the barbell was
elevated above the participants’ head, and then, moving down
just below an imaginary line of the bench. For the horizontal
bench press, we used a bar measuring 1.30 m long, mass of 10
kg, a horizontal bench press and Physicus ® washers (Brazil).
Hands were positioned on the barbell, which was individually
adjusted with a variation from 10 to 30 cm out of the shoulder
joint (Wagner et al., 1992). In the initial position of the move-
ment, individuals lay down on the bench in a supine position,
with their feet at on the ground, holding the barbell with a
pronated grip to start the exercise. At the start of the eccentric
phase of the movement, participants were instructed to direct
the barbell in a line near the central region of the sternum. The
end of the eccentric phase and the beginning concentric one
occurred when the barbell was moved near 2 cm of the chest.
Participants were instructed not to touch the chest with the
barbell in order to prevent the electrodes to move or to detach
while performing the exercise.

Electromyography
To avoid potential interference with the EMG signal,
each participant’s skin area was prepared before placing the
electrodes through the processes of trichotomy, abrasion and
cleaning with isopropyl alcohol. Two electromyography Mio-
tool 400 (Miotec Biomedical Equipment Ltd., POA, Brazil
®
)
with 4 input channels, 14 bit resolution and an acquisition
rate of 2,000 per channel samples, with a sensor SDS-500
with a maximum gain of 1000 times were used for the data
collection with Common Mode Rejection in 110 dB. The
electrodes used were 3M
®
model 2223BR, with a catchment
surface with Ag/AgCl 1 cm diameter in the shape of discs.
The electrodes were attached to the individual’s body accor-
ding to the points proposed by Merletti et al. (1999), respec-
ting a distance of 2 cm, and parallel to the muscle bers. The
low impedance of the skin was evaluated (< 2kΩ) and each
channel of the electromyography was properly calibrated
before the data collection. After attaching the electrodes in
the muscles portions to be analyzed, the biding sites were
marked with demographic pencil to avoid any interference
between evaluators and the different days on which the tests
were applied. All measurements were taken on the right side
of the individual’s body. Reference electrodes were placed on
the clavicle and the styloid process of the ulna. Electromyo-
graphy data were collected and stored in a personal computer
(Samsung RV411, Samsung, Brazil).
Signal processing
Signals collected were ltered through 5
th
order Butte-
rworth band-pass type lter with a 20-500 Hz cutoff fre-
quency. The amplitude of the signals was expressed by the
square root of the average values. To avoid any possibility
of phase delay during the signal ltering, an extended time
of EMG signal was determined with an interval of 1 minute.
For analysis and data processing Miograph 9 Build 2.0 Alpha
5 software was used.
Data organization process for statistical analysis
From the raw signal (RAW) it was possible to make a cut in
the original signal of 12 repetitions (48 seconds) in a new signal
of 8 repetitions (36 seconds), i.e., we excluded the rst two
and the last two repetitions. We adopted these criteria in order
to prevent the sample from failing to exert the proper speed of
execution during the initial and nal moments of the exercise,
thus minimizing the chances of error. Soon after, the new signal
was handled from the 5
th
order band-pass type Butterworth lter
with a cutoff frequency of 20-500 Hz. The electromyographic
signal amplitude was calculated in RMS (Root Mean Square).
The signals were normalized according to the maximum peak
of the EMG signal. Then, mean signals of all participants were
obtained and transferred into the SPSS software version 20.0
(SPSS, Inc., Chicago, IL, USA) for statistical analysis.
Statistical analysis
Data analysis was performed with statistical comparison
of averages and standard deviations. In order to investigate the
distribution of the sample, Shapiro-Wilk test was used. Statis-
tical analysis of the activation of muscle groups between the
horizontal bench press and barbell pullover exercises adopted
the t-test for independent samples. To identify the performan-
ce between muscle activations within each exercise, t-test for
dependent samples was adopted. In order to verify the effect
size of the sample test, d Cohen was adopted. For statistical
evidence α < 0.05 was adopted.
Results
The ICC between repetitions was 0.99 (lower limit= -0.003,
upper limit= 0.281). Figure 1 shows the comparison of elec-
tromyography activity of the major pectoral clavicular portion
between the horizontal bench press and barbell pullover exer-
cises (p < 0.01, d = 0.628, moderate effect size). The results

indicated signicant differences between the horizontal bench
press and barbell pullover.
In Figure 2, we observed a signicant difference between the
studied exercises regarding electromyography in major pectoral
sternal portion (p < 0.01, d = 0.453, moderate effect size). In the
analysis of Figure 3, it was identied that the barbell pullover
shows a statistically signicant higher electromyographic acti-
vity than the horizontal bench press for the long portion of the
triceps (p < 0.014, d = 0.268, small effect size).
When checking the results of the anterior deltoid (Figure
4), we observed a higher electromyographic activity during the
horizontal bench press compared to the barbell pullover (p <
0.01, d = 0.802, large effect size). Figure 5 shows the result of
posterior deltoid, in which we found no signicant difference
between both exercises (p < 0.812).
Figure 6 shows the latissimus dorsi muscle’s electromyo-
graphy, in which we found a signicant difference between
barbell pullover and horizontal bench press (p < 0.012, d =
0.303, small effect size).
Discussion
Based on the analysis of the results it was possible to conrm
the initial research hypothesis. The anterior and upper body mus-
cles activity showed signicant differences in the CPPM, PMSP,
LPTB and AD muscles. During horizontal bench press, CPPM,
PMSP and AD muscles showed higher levels of EMG activity
in comparison with the barbell pullover. These results show that
horizontal bench press presents concentric and eccentric phases
only in the front and the upper part of the body, while the barbell
pullover has the end of its eccentric phase and the beginning
of its concentric one located in the posterior and upper body
part—during which the pectoralis major musculature are most
requested, being responsible for performing the exion of the
glenohumeral joint (Smith, Weiss, & Lehmuhl, 1997; Wirhed,
1986). Another major factor that may have inuenced a divergent
electromyographic response between the two exercises relates
to the shoulder joint’s movement biomechanics. While in the
horizontal bench press shoulder shows horizontal adduction and
abduction (Hall, 1999; Marchetti & Uchida, 2011) movements,
in the barbell pullover the shoulder shows exion and extension
(Graham, 2004; Marchetti & Uchida, 2011) movements.
During the barbell pullover, LPTB showed higher levels of
EMG activation in comparison with the horizontal bench press
(Figure 3). This higher activity of LPTB during barbell pullover
was mainly attributed to the isometric action of this muscle,
emphasized by a slight elbow exion during the movement. This
elbow exion occurred in the movements of all the evaluated
individuals, and apparently was due to the great distance be-
tween the axis (shoulder) and the resistance (represented by the
apparatus – barbell + weight), which increased signicantly the
isometric request of this muscle during exercise execution. On
the other hand, the horizontal bench press showed lower levels
of electrical activation mainly due to the grips separation relative
to the bi-acromial distance (Clemons & Aron, 1997; Lehman,
2005). The standard grip used during the horizontal bench press
basic execution did not allow the absolute recruitment of these
muscles during the nal concentric phase in which the extension
of the elbows occurred.

electromyographic activity found in our study in the LD muscle,
which shows a tendency of barbell pullover to show electrical
activity in the muscle in question (Takara et al., 2005).
In conclusion, the results of this study suggest that the barbell
pullover exercise cannot be indicated as an exercise for the front and
upper body muscles, and that the horizontal bench press exercise
is the most indicated to the training and development of this body
musculature region. It is appropriate to emphasize that a variety of
training programs that include specic exercises have been applied
to athletes in sports where equipment is controlled and/or directed
with a muscle complex of the front and the upper body parts (Es-
camilla & Andrews, 2009; Schick et al, 2010). Training protocols
show great applicability of these exercises in the treatment of pa-
thologies located in the shoulders (Dorrestijn et al, 2009; Kuhn et
al, 2009). Taking into account the specic movement of the barbell
pullover exercise, as well as the similarity of this exercise with the
varieties of movements performed during some sports modalities
that require exion and extension of the shoulder joints, injuries or
pathologies in these musculatures can be prevented.
Barbell pullover is indicated as a good transition exercise from
the anterior to the posterior portions of the body. With regard the
adjustment of the barbell pullover in training programs, we sug-
gest its application in agonist/antagonist training to provide take
advantage of the transitional potential offered by this exercise. In
sports, the barbell pullover could be usually prescribed as part of
strength training for athletes in many sports modalities, both for
performance improvement, enhancement of strength and power,
and for the prevention of injuries (Dorrestijn et al., 2009; Kuhn et
al., 2009) that may result from repetitive movements above the
shoulder line (Schae, Requa, & Patton, 1990; Watkins & Green,
1992). In such situations, glenohumeral joint is often requested
due to the exercise specicity degree that is very similar to mo-
vements of serving and cutting in volleyball, serving in tennis
and pitching in baseball, to name a few examples.

With regard the posterior and upper body muscles, the results
showed a signicant difference in the LD muscles, but they did
not show differences in the PD muscles (Figure 5). During the
barbell pullover, LD muscles showed higher levels of electrical
activation regarding the horizontal bench press (Figure 6). This
LD tendency of showing higher electromyographic activity
during the horizontal bench press can be explained by the mo-
vement characteristic itself, which begins concentric phase and
ends eccentric phase at the posterior part of the trunk.
In summary, from the results of this study, the horizontal ben-
ch press still appears as an essential exercise for the development
musculature of the anterior and upper chest, given the higher
levels of electrical activation regarding the barbell pullover.
Thus, when the primary goal is the development of the anterior
and upper body muscles, the horizontal bench press exercise and
its variations still stands out as having the greatest magnitude
in comparison with the barbell pullover. We recognize that this
study has limitations as we did not use other variations of bench
press with different bench angles, dumbells, machines and other
exercises in order to compare with the barbell pullover. Howe-
ver, other studies (Cachio et al., 2008; Sadri et al., 2011; Schick
et al., 2010; Trebs, Brandenburg, & Pitney, 2010; Welsch, Bird,
& Mayhew, 2005) comparing the horizontal bench press with
other bench press variations fail to nd signicant differences
on levels of electrical activation on the studied muscles. Such
evidence allows one to classify these variations or exercises as
complementary, or (most of them) primordial and effective for
the anterior and upper body development.
Therefore, according to our ndings we cannot classify the
barbell pullover as a complementary exercise, nor primary for
the development of the anterior and upper body muscles. This is
due primarily to three factors: the EMG activation levels in the
evaluated muscles, and, specically, in the portions of the pecto-
ralis major, which are practically duplicated when comparing the
horizontal bench press with the barbell pullover; the movement of
the shoulder joint, (while in the barbell pullover we have exion
and extension movements, in all other variations and exercises
that have been studied, we have the horizontal abduction and
abduction movements) (Marchetti & Uchida, 2011); and the

dorsi between horizontal bench press and barbell pullover exercises
