Research on the Application of Newton's Laws of Motion to Counter-Movement Vertical Jumping » of an individual, particularly the power and strength of the lower limbs. has been used both by the general population and by high-level sports. Vertical jump height is measured as the difference between the position of the individual's center of mass in the starting position (a standing position) and their position at maximum height.

Get an original essay There are many methods of collecting data from CMJ, but a widely accepted and reliable method requires the use of a force plate that uses the ground. reaction forces to calculate variables such as maximum power, maximum rate of force development and jump height. “Force plates are very sensitive to errors in force magnitude and center of pressure location and are also used to assess foot placement and variability during human walking, again with high error sensitivity” . This equipment also measures the force produced over time, the magnitude of the force and when it occurs, and "if the body of a mass is known, the kinetic data can be used to inform the kinematics of the center of mass of the body in terms of acceleration, speed and displacement. “On the other hand, it appeared that center of gravity models can cause errors which disqualify their use as a criterion for validating kinetic parameters.” Several studies have attempted to explain force-time graphs derived from CMJ, but with mixed results regarding sex differences. For example, Laffaye (2014) attributed sex differences in CMJ height to males' ability to demonstrate greater relative (relative to body mass) maximum concentric strength, as well as a higher rate of development higher average absolute and relative eccentric force (RFD). However, in contrast, Ebben (2007) found no gender differences in CMJ RFD or movement time. Similarly, Rice (2017) reported no gender differences in peak strength or RFD calculated from the CMJ. In order to begin analytical research and coaching from the statistics and information provided, it is essential that Newton's laws are understood and used to explain how individuals control their movements with force. Newton developed three laws that perfectly describe the relationship between force and motion. The aim of the present study is therefore to distinguish the relationship between Newton's three laws and the CMJ and to use these laws to explain the force changes throughout the CMJ.MethodologyParticipants Two participants (one male: age: 20 years , height: 185 cm, body mass: 78.2 kg; a woman: age: 20 years, height: 162 cm, body mass: 59.8 kg) without a history of musculoskeletal impairments gave written consent to participate in this study. Ethical approval was sought and granted from the University Research Ethics Committee. Procedures Prior to data collection, participants completed a dynamic warm-up and were familiarized with all procedures. Participants were asked to stand with their feet shoulder-width apart and place their hands on their pelvis. Participants were asked to squat at aself-selected depth and perform the CMY as quickly and as high as possible. Data collection CMJs were recorded using two force plates with a sampling rate of 1000 Hz. Body weight was determined before the start of CMJ. Raw vertical force-time data were exported and analyzed using a Microsoft Excel spreadsheet. Data analysis Data were analyzed via an Excel spreadsheet (version 2016, Microsoft Corp., Redmond, WA, USA). Net force was calculated by subtracting the participant's weight from the original force. Acceleration was then solved by dividing net force by body mass; velocity was determined via the trapezoid rule (integration) using acceleration versus time data; displacement is then calculated based on velocity versus time. Results The overall results from this laboratory suggest that males can produce more overall force and more force per kg of their body weight. The male also achieved greater acceleration and speed, but his displacement was less than that of the female. Even though the men's displacement was lower, they still achieved a higher jump than the women's, suggesting that there is a relationship between normalized force and jump height. DiscussionThe CMJ has three stages: lightening phase, braking phase and propulsion phase. Each can be explained via Newton's laws of motion. Newton's first law of inertia explains the deweighting phase by stating that "Every body continues in its state of rest, or of uniform motion in a straight line, unless it is compelled to change this state by forces which are imposed on him” (Newton, 1987). . As shown in Figures 1 and 2, both individuals cause a negative external force, breaking their state of resting inertia and resulting in negative velocity. The maximum descent speed is reached at the end of the deweighting phase. Therefore, an upward force must be applied to bring the speed down to zero, as shown in Figures 1 and 2, during the braking phase where a massive force is applied. Additionally, throughout the movement, Newton's first law is still in effect because there is a constant change in speed, which must mean that a constant force is being applied to the body weight. Newton's second law states that "the acceleration of an object depends directly on the net force acting on an object, and inversely on the mass of the object." As shown in Figures 1 and 2, there is a proportional change in shape in acceleration because there is a change in force explaining that “F = M x A”. Additionally, when either subject applies a downward force, a negative acceleration occurs and when a positive force is applied, a positive acceleration occurs. Newton's second law also states that "the acceleration of a given force is inversely proportional to the mass." The maximum force produced by participant 2 is approximately 1400 N, which causes an acceleration of 15 m/s². However, looking at the results of the participant, who has the greatest mass, the acceleration produced at 1400N is less than 10 m/s², which further supports Newton's 2nd law. The braking phase consists of the subject continuing to descend and only ends when the subject stops and does not have zero speed, this is when the huge peak of force applied can be seen as this is the point where the subject applies positive force to change. their movement from bottom to top. Towards the end of the braking phase, when the subject stops and reaches zero speed, this is the moment when the maximum force is at its maximum. This surge of force can.
