The Impact of Biomechanical Principles on Participant Performance

This report examines the application of biomechanical principles in the context of shoulder press exercises. It delves into the influence of various forces, including pushing and pulling forces, and reaction forces, on participant performance. The study further explores the concept of the center of mass and its role in overall body movement during the exercise. The report highlights how changes in exercise techniques and equipment can manipulate these forces to enhance participant performance in fitness activities. The analysis is based on Newton's third law, and the impact of biomechanical principles on the participant's ability to move the equipment and lift the bar is thoroughly discussed. The conclusion emphasizes the significance of biomechanical principles in optimizing fitness activities and the potential for improving individual performance through strategic adjustments.

INTRODUCTION
Biomechanics is a kind of study of the action of internal and external forces on the living
body. It defines the investigation of the structure and functioning of biological systems of human
being. This can be considered as a quantitative based learning and analysis of sports and athletes
activities (Nahum and Melvin, 2012). The present report is based on the biomechanics principles
and to understand its importance, shoulder press up and down exercise is taking to the
consideration.
Impact of biomechanical principles in influencing the participant performance
Pushing or pulling forces:
There are various biomechanical principles that use in sports ort faintness activities in order
to determine the impact of forces on the participants. In this context, first force is pulling or pushing
(Poitout, 2013). Pulling force applies in the case of when the object is not moving or in stationary
situation. The reason of moving this is gravity. While pushing force impose in that condition when
the object is in moving and require some kind of pressure which should be more than accelerate
force. In the case of shoulder press up and down, pulling and pushing both forces have applied
(Diakides, Bronzino and Peterson, 2012). When the participant pushes the shoulder press equipment
which has in stationary position then the impact of this applied force is machine cause acceleration
with some amount of the velocity. This will be change over a period of time when the applied
pushing force increase. On the other hand, when applicant applied pulling force in the opposite
direction of the motion of exercise machine then object will decelerate or slow down. This shows
that when the participant implies pushing force, the impact of it on him is he will able to move the
entity. In the case of pulling force, the effect of this is the contestant will stop the moving shoulder
machine object with greater force (Rieder, Dunst and et.al., 2012).
With the help of pushing or pulling biomechanical forces, the participant performance can
be changed. For this, by making changes in the structure or weight of the equipment of exercise, it
becomes easy to minimize the forces which are applying by the individual at the time of doping
shoulder exercise. In addition to this, by making modifications in techniques of perform exercise,
pushing or pulling force can be manipulated to influence the participant performance (Robertson
and et.al.,2013).
Reaction forces
As per the Newton’s third law, every action force there is an equal and opposite reaction
force. Action and reaction forces always come in pairs. This can be determined with the help
identifying the two interacting objects and preparing two statements describing who is pushing on
3

whom and in which direction. In the case of physical fitness activity should press up and down,
reaction force has effective work. The working of the following act can be understood by an
example (Amis, 2013). If shoulder machine object weight is 10 kg then the participant weight
should be about to 50kg to carry out the exercise of shoulder press up and down. In this situation, he
has to applied action force on the bar to move it on the equipment and in this case, same amount but
an opposite force also applied and it is called reaction force. Till when both forces will in equal
amount then they will be zero and the result of this, bar would not move. But when contestant
impose more force as compare to opposite act then the bar will start top move. The impact of this
activity on the participant is he has to applied more forces at the time of doing shoulder press up
and down exercise (Valdes and von der Heyde, 2012). By making changes in the techniques of the
applicant of performing the exercise, his performance can be improved. Along with this, by
maintaining the weight of the bars as per the weight of the person body, performance of participant
can also increased.
Center of mass
The shoulder up and down activity impacts the overall body movement of the participants.
During the performance of the activity center of mass at the time of take off gets displaced in the
vertical direction. The equipment used under the shoulder exercise machine moves up and down
while performing the activity (Jepsen and et.al., 2015). The muscles of the person come under a
constant load. Regular practice of this exercise aid in increasing strength of the muscle. Overall
body mass is produced and made efficient. The bar of the equipment travels in vertical directions
and due to that in the middle of movement a pull against gravity is observed. The individual who
get involved in the exercise lift the bar from his upper thighs towards the chin in a circular path.
Initially the movement of the bar is in the horizontal directions but when more loads is applied on
the bar it starts moving in the vertical directions. It is required that the practitioner should constantly
pull the bar and try to bring in the center position. At this point the equipment bar is pulled against
the gravity (Nahum and Melvin, 2012). When the person reaches at the top position the pressure on
the shoulder pressing machine starts decreasing. While performing the exercise it is required that
the practitioner should come at the mean position of the system which is used for performing the
exercise. At this point the shoulder pressing machine starts responding towards external force
applied by the individual. The whole exercise revolves around balancing center of mass which is
described as a position under which the whole mass of the person is concentrated on the equipment
on which the exercise is performed. The practitioner can lift the bar with little force in the initial
movement so that more strength required to be applied in the middle section of the activity. It will
aid in gaining more strength for the muscles (Poitout, 2013).

CONCLUSION
On the basis of the above report, it can be concluded that biomechanical principles have
played an important in fitness activities. Pushing or pulling, reacting force and centre of mass forces
has helped in manipulated the participant performance. Along with this, by making changes in
doing exercise and machines used for it, the performance of individual can enhanced.
