Abstract:
This study analyzes the upper div kinematics
of volleyball players during ball-entry actions, focusing
on the shoulders and elbows. Utilizing maximum and
mini-mum flexion, extension, and abduction/adduction
values, the research highlights the functional
asymmetry between the dominant and non-dominant
arms during serving and spiking. The results show that
the right shoulder and elbow, as dominant joints, are
responsible for generating most of the force needed for
effective ball entry, while the left arm stabilizes and
balances the div. The findings provide insights into
per-formance optimization and injury prevention
strategies, particularly for managing overuse injuries in
the dominant arm.

Introduction:
Volleyball is a sport that demands a high
level of coordination, precision, and power, particularly
during ball-entry actions like serving and spiking. These
actions require the integration of both upper and lower
div movements, especially involving the shoulders
and elbows for force generation, as well as the lower
limbs for stability and explosive jumps. The complexity
of these movements presents challenges for op-timizing
performance and minimizing the risk of injury.

Understanding the kinematic patterns of volleyball-
specific actions is essential for improving athletes'
biomechanics, enhancing efficiency, and preventing
overuse injuries, particularly in the dominant arm. In
overhead sports such as volleyball, it is common for the
dominant arm to exhibit a higher range of motion,
contributing to greater power output during actions
like spiking or serving. However, this functional
asymmetry can lead to increased strain on the
dominant shoulder and elbow, making injury
prevention a critical aspect of training programs.
Previous research has shown that the asymmetry in
joint function, especially be-tween the dominant and
non-dominant limbs, plays a significant role in both
perfor-mance and injury risk (Ford et al., 2003;
Schneiders et al., 2011). The repetitive use of the
dominant arm for spiking and serving often results in
greater strength and mobili-ty on that side, while the
non-dominant arm stabilizes the div. This imbalance,
while beneficial for performance, can increase the
likelihood of overuse injuries, in-cluding rotator cuff
tendinitis and elbow strain.
The present study focuses on analyzing the kinematic
indicators of volleyball players during ball-entry
actions. By employing advanced 3D motion analysis
tech-nology, we assess both upper and lower div
movements to gain a comprehensive understanding of
the biomechanical forces involved. Specifically, this
study examines shoulder flexion, extension, abduction,
and adduction, alongside lower div mechan-ics such
as pelvis rotation, hip flexion/extension, and knee and
ankle movements.
Previous research on volleyball biomechanics has
extensively examined the role of the shoulders and
elbows in overhead actions such as serving and spiking.
Studies have consistently demonstrated functional
asymmetry between the dominant and non-dominant
arms, with the dominant shoulder and elbow
contributing most of the force required for ball entry
(Pappas & Carpes, 2012). This asymmetry, while
enhancing performance, poses a significant risk for
overuse injuries due to the repetitive high-intensity
movements involved in volleyball (Ford et al., 2003).
Shoulder flexion and extension are particularly critical
for generating the power necessary for effective serves
and spikes. Bobbert et al. (1990) emphasized the im-
portance of full shoulder and elbow extension in
maximizing ball velocity. Similarly, Schneiders et al.
(2011) highlighted the role of shoulder mechanics in
both perfor-mance and injury prevention, noting that
inadequate flexibility in the shoulder joint can lead to
higher injury risks, particularly during repetitive
overhead movements.
Abduction and adduction also play key roles in
maintaining stability during dy-namic movements. This
is essential for keeping balance while adjusting to the
high-speed, lateral movements required for spiking or
blocking (Chang et al., 2019). While the dominant
shoulder focuses on force generation, the non-
dominant shoulder pro-vides the necessary stability,
and symmetrical movement between the two helps
main-tain postural balance.
The lower div also plays a critical role in volleyball,
particularly in terms of generating the initial push-off for
jumps and stabilizing the player during landing. Pelvis
rotation is vital for transmitting force from the lower
div to the upper div during serves and spikes
(Bobbert et al., 1990). Asymmetries in lower div
kinemat-ics, such as hip flexion/extension and knee
movement, can also affect performance, with the
dominant leg typically generating more force, while the
non-dominant leg stabilizes the div (Pappas & Carpes,
2012).
The analysis of flight and support times, as well as step
length during volleyball-specific movements, provides
further insights into how players use their lower limbs
to optimize performance. For instance, shorter step
lengths, combined with efficient cadence and support
times, help athletes maintain balance and agility,
allowing for rapid changes in direction during ball-entry
actions (Lees et al., 2004).
The
literature
supports
the
importance
of
understanding both upper and lower div kinematics in
volleyball players. The functional asymmetry between
the domi-nant and non-dominant limbs, while crucial
for optimizing performance, presents po-tential risks for
overuse injuries, particularly in the shoulders and
elbows. To mitigate these risks, training programs must
focus on balancing strength, flexibility, and stabil-ity
across both limbs, incorporating exercises that promote
symmetry and reduce inju-ry risk while enhancing
performance.
By integrating advanced 3D motion analysis technology,
this study aims to pro-vide a comprehensive
biomechanical
evaluation
of
volleyball-specific
movements, of-fering insights that can be applied to
improve training methods, performance out-comes,
and injury prevention strategies for elite volleyball
players.

University of Physical Education and Sports in the high-
tech laboratory of Sport, equipped with advanced 3D
motion analysis technology. The sophisticated lab
setup allowed for precise measurements of
biomechanical parameters, making it an ideal
environment
for
studying
detailed
athletic
movements. A candidate athlete for Master of Sports
in volleyball, who possesses extensive competitive
experience, was selected as the subject of the study.
The experiment focused on analyzing the shoulder
mechanics during the execution of serves and spikes,
with an emphasis on kinematic and kinetic data related

volleyball.
METHODS
The study employed advanced 3D motion analysis
technology
to
conduct
a
comprehensive
biomechanical evaluation of shoulder movements
during volleyball ball-entry actions. The research took
place in the high-tech laboratory at the Uzbek State
University of Physical Education and Sports. The
participating athlete’s serves and spikes were captured
using a high-resolution 3D motion capture system,
which included multiple infrared cameras placed
strategically around the laboratory to track movements
from various angles.
Reflective markers were attached to key anatomical
landmarks, including the shoulders, elbows, spine, hips,
knees, and ankles, to gather precise data on joint angles,
shoulder movements, and overall div posture during
ball-entry actions. This setup allowed for an in-depth
analysis of the kinematic indicators, specifically
examining how shoulder flexion, extension, abduction,
and adduction contribute to the effectiveness of serves
and spikes. The detailed motion data provided insights
into the shoulder and lower-div mechanics that are
crucial for executing powerful and accurate ball-entry
techniques in volleyball.
RESULTS
In volleyball, movement dynamics during ball-entry
actions such as serving or spiking involve complex
coordination between various div segments, including
both upper and lower limbs. Analyzing gait-run
temporal parameters helps us better understand the
athletes' biomechanics, especially in terms of efficiency
and power generation. The following section provides a
detailed analysis of the gait-run temporal parameters of
volleyball players during the ball-entry process.
The key gait-run parameters presented include
cadence, flight time, support time, and step length, as
well as the disparities between the right and left limbs.
These parameters are essential for understanding how
players transition between movements, particularly the
phase between running/jumping and ball entry.
Cadence refers to the number of steps taken per
minute. A cadence of 132.11 steps per minute is typical
for high-intensity sports like volleyball, where players
need to rapidly adjust their positions during ball entry.
This value indicates efficient movement, as volleyball
players must maintain a balance between rapid
footwork and stability.
In volleyball, the need for quick lateral and vertical
movement is crucial, particularly when preparing for
explosive actions like serving and spiking. Mero et al.
(1983) explored the importance of cadence in high-
intensity sports, finding that athletes with faster, more
efficient cadence often exhibit better performance due
to improved foot coordination and stability.

Flight time refers to the duration the player spends
airborne between steps. A flight time of 0.66 seconds
suggests the athlete is making rapid, forceful
movements to prepare for ball entry. The longer flight
time compared to support time indicates a focus on
explosive movements, which are crucial for creating
the vertical lift needed for powerful spikes and serves.
Flight time is a critical indicator of a player's ability to
generate force during jumping. Lees et al. (2004) found
that in volleyball, flight time correlates with jump
height and power output during serves and spikes.
Greater flight time typically means the player is better
able to generate vertical lift, which is essential for high-
level performance in volleyball.
Support time refers to the duration the player’s foot is
in contact with the ground during each step. A support
time of 0.61 seconds indicates the player spends a
considerable portion of time on the ground between
each airborne phase. This support time is necessary for
stabilizing the div before jumping for the ball. In
sports like volleyball, support time is crucial for energy
absorption and preparing for subsequent explosive
movements. Bobbert et al. (1990) emphasized the
importance of support time in jump preparation,
highlighting that longer support times allow for greater
force production, improving jump height and accuracy.
Step length measures the distance covered in a single
step. A step length of 114.75 mm indicates relatively
short, controlled steps, typical in volleyball, where
players must move efficiently within a small area to
position themselves for the ball. Shorter step lengths
in volleyball can be linked to the need for rapid, agile
movement. Pappas et al. (2012) found that shorter
steps allow players to quickly change direction and
maintain balance, which is especially important during
high-speed movements such as preparing to spike or
serve.
Right Flight Time (0.1250 seconds) vs. Left Flight Time
(0.3250 seconds). The difference in flight times between
the right and left sides suggests asymmetry in how the
athlete generates power. The left leg spends more time
in the air, which could imply that the athlete relies more
on the right leg for support and force generation.
Right Support Time (6.4833 seconds) vs. Left Support
Time (5.5583 seconds): The significant disparity
between the support times of the right and left legs
indicates a dominant leg (right) that bears more weight
and plays a larger role in stabilization during
movements.
The asymmetry in limb function is common among
volleyball players, particularly in those with a dominant
side. Pappas and Carpes (2012) studied kinematic
asymmetry in athletes and found that dominant-leg bias
often leads to differences in flight and support times.
While this asymmetry helps in performance, it can also
increase the risk of overuse injuries if not addressed
through balanced training.
To optimize performance, training programs should
focus on improving flight time and step length while
ensuring balance between the dominant and non-
dominant legs. Bobbert et al. (1990) found that
increasing flight time through plyometric training can
enhance jump height, while improving cadence and step
length through footwork drills can boost agility and
speed in volleyball players.

The spatial parameters of gait-run movements offer
insight into how volleyball players manage forces,
balance, and propulsion during critical ball-entry
actions such as serving and spiking. This analysis
explores key spatial parameters, such as the vertical
oscillation of the center of gravity (COG), braking and
propulsion distances, and foot positioning. By
examining these parameters, we can better
understand the biomechanics involved in volleyball
players’ movement efficiency, stability, and pow
er
generation (Table-2).
COG Vertical Oscillation (560.21 mm). COG vertical
oscillation measures the upward and downward
movement of the player’s center of gravity during
motion. A vertical oscillation of 560.21 mm indicates a
significant change in COG, which is essential for
preparing for jumps during serving or spiking actions.
A higher COG oscillation is typically associated with
more dynamic movement and greater jump potential.
Lees et al. (2004) noted that a greater vertical
displacement of the center of gravity is correlated with
higher jump heights and greater power generation in
volleyball players. Efficient COG control is crucial for
maintaining balance and executing precise ball-entry
actions.
Right Braking Distance (94.05 mm) vs. Left Braking
Distance (259.77 mm). Braking distance refers to the
length over which the player decelerates during
movement. The difference between the right and left
braking distances is significant, with the left side
showing a much longer braking distance than the right.
This asymmetry suggests that the left leg is involved
more in deceleration and stabilizing the div during
rapid movements, while the right leg may be more
focused on forward propulsion. Pappas and Carpes
(2012) found that such asymmetries in volleyball
players, especially in braking mechanics, can lead to an
uneven distribution of forces, increasing the risk of
overuse injuries in the dominant leg.
Right Propulsion Distance (-436.30 mm) vs. Left
Propulsion Distance (180.84 mm). Propulsion distance
measures how far the player moves forward during a
stride. The negative value for the right propulsion
distance indicates a backward motion, likely related to
preparatory movements for a jump or quick changes in
direction. In contrast, the left leg's positive propulsion
distance shows forward motion, which might be linked
to maintaining balance during ball entry.
The backward motion of the right leg suggests it plays a
key role in preparing for explosive movements, such as
jumping for a serve or spike. Bobbert et al. (1990)
discussed the importance of leg propulsion in
generating vertical lift during jumps, emphasizing the
need for effective backward motion to preload the leg
muscles for power generation. The imbalance between
right and left propulsion distances may indicate the right
leg's primary role in generating this explosive force.
Support Distance for Right Contacts (413.55 mm) vs.
Left Contacts (457.47 mm). Support distance refers to
the horizontal distance covered during the stance phase
when the foot is in contact with the ground. The left leg
has a slightly longer support distance than the right leg,
indicating that it may be more involved in providing
stability.
This slight asymmetry could indicate that the left leg
plays a more significant role in stabilizing the div
during rapid movement, while the right leg is more
involved in generating power. Ford et al. (2003)
highlighted that volleyball players often show
dominance in one leg, with the other leg acting primarily
for stability and control. These differences in support
distance could reflect such a functional asymmetry.

CONCLUSION
This study provides a comprehensive analysis of the
kinematic indicators of volleyball players during ball-
entry actions, with a specific focus on upper div
movements involving the shoulders and elbows, as
well as the supporting role of the lower div. The
results highlight a clear asymmetry between the
dominant and non-dominant limbs, particularly in the
range of motion of the right shoulder and elbow, which
are responsible for generating most of the force during
serves and spikes. In contrast, the left shoulder and
elbow function primarily to stabilize the div,
reflecting the biomechanical demands of volleyball.
The findings underscore the importance of addressing
functional asymmetry in training programs to improve
performance while reducing the risk of overuse
injuries. Specifically, volleyball players should focus on
balancing strength, flexibility, and control between the
dominant and non-dominant sides of the div to
ensure that the repeated use of the dominant arm
does not result in chronic injury conditions such as
rotator cuff tendinitis or tennis elbow.
Moreover, the lower div plays a critical role in force
generation and stability, particularly during jumps and
landings. Pelvis rotation, hip flexion/extension, and
knee and ankle movements contribute significantly to
overall performance. The coordination between upper
and lower div kinematics is essential for efficient and
powerful ball-entry actions.
In conclusion, this research emphasizes the need for
tailored training programs that not only enhance the
power and precision of volleyball players' movements
but also address the potential for injury due to
asymmetry. By integrating balanced conditioning,
athletes can optimize their performance and prolong
their careers in the sport.
