Comparative Analysis of Underarm and Overarm Throwing in Cricket

This project delves into the comparative analysis of underarm and overarm throwing techniques within the context of cricket, focusing on the biomechanical distinctions between the two methods. The study examines a male cricket player, analyzing the preparation, execution, and follow-through phases of each throw type. Using Kinovea software and a high-definition camera, the project records and analyzes the angles between the shoulder and elbow joints, aiming to identify key differences in movement patterns. The research highlights the importance of muscle contraction, noting that underarm throws necessitate more flexion, engaging biceps and anterior deltoid fibers, whereas overarm throws require more extension, involving triceps and posterior deltoid fibers. The project underscores the significance of these differences in enhancing cricket players' performance, offering insights into the dynamics of throwing speed and accuracy.

Abstract
Background: Underarm and overarm throw are very important in the field of cricket.
Understanding the difference between the two is highly significant for researchers and
players alike.
Objectives: The study aimed at identifying the difference between underarm and overarm
throwing techniques among male cricket players.
Methodology The study investigated the difference between overarm and underarm throwing
techniques in male cricket player. The results were analysed and recorded by software
Kinovea. The angles between shoulders and elbows were recorded for both throws and
divided into three phases: preparation phase, execution phase and follow through phase. A
Panasonic HC -V130 High definition camcorder camera was used to capture the data.
Findings and Conclusions: From the study it was identified differences exist between
underarm and overarm throws among male cricket players. The study attributes the
difference between underarm and overarm throw to the noticeable difference between the two
during the processes of preparation, execution and follow through phases. The underarm
players need more flexion while the overarm players need more extension. For an underarm
throw, therefore, good biceps and anterior fibres of the deltoid are needed for contraction.
However, for an overarm throw, triceps and posterior fibres of the deltoid are needed for
contraction as well. This notable differences are significant in analysing the underarm and
overarm cricket players.

Introduction
Throwing bears a high level of significance within sports. Throwing with precision
and with speed is an inherent human activity which most humans possess. In cricket as a
sport, the speed and accuracy of a throw is essential if one is to achieve the highest level of
performance. The speed and accuracy of a throw is dependent on many factors including
whether the throw was an underarm or an overarm throw. However, the speed and accuracy
has not been fully understood owing partly to the fact that few researches have been done to
deal with the aspect in particular. This research analyses the particular aspects of underarm
and overarm throws as factors inherent to throwing speed and accuracy.
Differences between underarm and overarm throw
There are specific distinctions that exists between underarm and overarm throws
which support their uniqueness in speed and accuracy during playing. In terms of being fast
an accurate, one study conducted by researchers proved that an underarm or underhand throw
was more precise compared to an overhand throw. However, this is proved different in cases
where the player is less than three arms in length away from the from the shoulder height. In
such a case, a very gentle overhand toss would be more effective to achieve the needed
results. The underhand throw is preferred by many players because of its effectiveness.
Cumulatively, a clear distinction between the underarm and overarm throw can be
made specifically because of the way in which the throws are initiated other than the
accuracy level. The overarm throw is initiated by having arms placed over the elbow before
releasing the ball. However, in cases of the underarm the ball is placed below the level of the
elbow before it is released. The way in which muscles are used during the initiation of the
underarm and overarm throw also varies. The whole body is however employed during the
initiation of an underarm throw. The latismus dorsai, however, is the muscle that is most used

during the initiation of an underarm throw. The muscles that are used for an overarm throw
are however different.
Throwing is not only utilized in fielding (in cases where the right arm is used) but
also when the batsman hits the ball to the bowler. The overhead throw is highly utilized by
the defender. The defenders utilize the overhead throw to get the ball back to the wicket
keeper’s gloves or stumps. Along these lines, the overhead throw is essential for influencing
run-outs (cases where the batsman is rejected for his or her inability to finish a run) and to
keep the opponents from scoring runs. Higher speed throws are essential in diminishing the
time needed by opponents to finish a run. In addition, higher speed runs affect the
fundamental decision of the opposing team player regarding whether a run can be finished
securely or his/her ability to influence a run-out.
Muscle strength and power are essential determinants of throwing speed in overhead
throwing and underarm throwing games including: baseball; water polo; cricket and
European handball. The amount strength and power used during playing has been correlated
with throwing speed. Training interventions have demonstrated improvements in strength and
power of throws and have had positive effects on throwing velocity in these games. The
impact of strength and power on speed gives a suitable strategy through which execution can
be enhanced in overhead throwing players. Overhead throwing players are able to be more
effective throw the initiation of strength and power in their throws.
The increase in speed and velocity in playing leads to the production of successful
results in the game of cricket. However, very few studies have investigated the connection
between strength, power and throwing speed in a gathering of cricket players. In spite of
there being few documented studies on this subject matter, this examination discovered
contrasts between faster and slower throwing cricketers on rotation movement. It utilized few

Running head: PRIYESH DESAI 5
strength and power control measures. Even though a few correspondents existed among
baseball and cricket players as far as the specific throwing movement utilized, important
contrasts exist which may modify the connection between strength, power, and throwing
speed for players who associated with this game. Cricket players are required to throw
heavier balls than baseball players (156 versus 142 g; around 10% distinction). These places
cricket players on an alternative type of force and velocity, which may change the relative
impact of strength and power on throwing speed. In addition, contrasts exist between cricket
players and baseball players as far as throwing execution and biomechanics. Cricket players
have appeared to have much lower maximal throwing speed (MTS) and accurateness
capacities and throw with expanded elbow flexion and lessened shoulder external rotation in
the preparation period of the throw contrasted to baseball players.;
The throwing movements are divided into 5– 6 individual phases that is: the
preparation phase (wind up replaces this phase in baseball), stride, arm cocking, acceleration,
deceleration, and follow through. The shoulder of the overhead throwing athletes, as a result
of the execution phase, must give sufficient flexibility (extension) to permit greatest external
rotation during the acceleration phase of throwing and enough steadiness to permit forceful
velocities as high as 7,510/s2. This fine adjust of adequate versatility and dependability has
been referred to as the "thrower’s paradox." Regardless of whether the required range of
motion in an adaptive reaction to throwing is undetermined.
The study conducted by muscles movements comparing sidearm throw with underarm
throw an overarm throw. The results observed more flexion during underarm throw ball than
sidearm throwing ball. Another finding was more amount of extension found in sidearm than
overarm throw. But this study didn’t explain any relationship between underarm throw an
overarm throw.

This article aims to recognize difference between overarm throwing and underarm
throwing a ball in male cricket players. This article player can expand muscle strength and
increment muscle growth through home-base situated exercises by dividing them in three
different phases. This study further determines difference between muscular contraction
relative with three different phases. It was hypothesis that the subject in this study will have
greater shoulder flexion and elbow flexion and create great volume during underarm throw
and overarm throw respected to the three different phases.

Methods:
Approach to problem:
This study investigates the difference overarm and underarm throwing techniques in
male cricket player. The results are analysed and recorded by software Kinovea. The angles
between the shoulder and elbow were recorded for both throws and divided into three phases.
Preparation phase, execution phase and follow through. A Panasonic HC -V130 High
definition camcorder (Osaka, Japan) camera was used to capture the data.
Participant
The participation in the study was on voluntary basis. One male volunteer of twenty
four years and three years of experience in cricket was recruited into the study. The study was
designed for male cricket players. The participant was played for Indian Ranji trophy and
Duplex trophies. The subject did not possess any shoulder or elbow injuries. The subject did
not poses any medical condition that would warrant attention.
Parameters and experimental setup:
Parameters used for experiment were preparation phase, execution phase and follow
though phase. In the preparation stage, a vast piece of the event that establishes an athlete for
his execution as per his capacity, for instance, behind the swing between cricket batting and
throwing in cricket. The execution stage is the accelerate stage which begins with speed and
finishes with losing the contact with the question (for instance, tossing the ball toward the
stump). The following phase is referred to all the movements of the execution phase (for
example, in the wake of throwing the ball), which slow back the body's movements. Events
used as parameters were overarm throw and underarm throw. The underarm throw is (of a
throw or stroke in sport) made with the arm or hand underneath shoulder level. The overarm

Running head: PRIYESH DESAI 8
throw is (of a throw or passing) made with the hand or arm going over the level of the
shoulder.

Procedure
The preparation was started before week example construction of structure sample of
set up. Subject were appropriate clothing which was required for this experiment i.e. T – shirt
or singlet, trousers with typical game shoes. On the test, day the camera was set on the games
running track in Tauranga sports ground. The camera was set as 5 m and parallel to the
subject. The stumps were placed opposite to the subject with 5 m distance. The camera was
faced toward the subject with the aim to get accurate shoulder and elbow angles. The subject
was instructed on to perform the underarm throwing and overarm throwing strategies. The
subject was instructed to aim at the stumps for 5 minutes with both underarm and overarm
throws for practice. The subject was marked on shoulder as well as elbow with marker.
Markers were placed on the glenoid tubercle on Humerus, the lateral epicondyles of Humerus
and at the lateral styloid process. Video was then to recorded for calibration. The subject
threw the ball first with underarm technique aimed towards the stumps. Video were recorded
three times. The same process was repeated for the overarm throw.
