Meaning
The term “biomechanics” combines the terms “bio” and “mechanics.” Bio is defined as something having to do with living things or life, whereas mechanics is the field of physics that analyzes how an object or body moves using mechanical principles. Thus, the study of mechanics that is restricted to the function of living systems, particularly the human body, is known as biomechanics.
There are two sub-fields of study under “mechanics.” The first is statics, which is the study of systems that are either at rest (without motion) or moving with a constant speed; the second is dynamics, which is the study of systems in motion with acceleration, which may involve kinematics and kinetics.
Kinematics
The study of body motion with regard to time, displacement, velocity, and speed of movement in either a straight line or a rotating direction is known as kinematics. Kinematics can be thought of as the “what” of motion. It’s about expressing how things move without worrying too much about why they move that way. In other words, it’s all about positions, distances, velocity, and acceleration.
Imagine a car driving along a straight road. Kinematics would help us answer questions like:
- How far has the car traveled from the starting point?
- How fast is the car going?
- Is the car speeding up or slowing down?
Kinetics
Kinetics is the study of forces involved in motion, including forces that initiate motion and forces that are a result of motion. Kinetics explains “why” motion occurs. Understanding the forces behind how things move is important. Forces, which are similar to pushes or pulls, can cause things to accelerate, slow down, or change direction.
Let’s continue with our car example: Imagine the car needing to stop suddenly because a ball rolled onto the road. Kinetics would help us answer questions like:
- How hard does the driver need to press the brakes to stop the car in time?
- What happens to the car’s speed and direction when the brakes are applied?
In its simplest form, kinematics is the study of how to describe motion, such as “the car traveled 100 meters in 10 seconds.” Kinetics is about the reasons behind motion, like saying, “The car stopped quickly because the driver pressed the brakes hard.”
Remember that kinetics explains why something is happening, whereas kinematics explains what is happening. Together, these two ideas allow us to fully comprehend motion!
Meaning of Sports Biomechanics
Sports biomechanics is a quantitatively based field of research that examines and analyzes professional athletes, sportspeople, and sports activities in general. It can be summed up simply as the physics of sports. In order to better understand athletic or sports performance, the laws of mechanics are applied to sporting events through mathematical modeling, computer simulation, and measurement in this branch of biomechanics.
The study of motion/movement and how forces affect motion/movement is the focus of the physics subfield known as mechanics. Sport biomechanics includes a thorough examination of athletic movements to reduce injury risk and enhance athletic performance. The field of study that examines the mechanics of human movement is known as biomechanics, and it includes both sport and exercise. The description, in-depth examination, and evaluation of human movement during sporting activities are included.
Sport biomechanics is the study of how and why the human body moves the way that it does. In the context of sport and exercise, this concept is frequently expanded to include the performer’s interactions with their tools and surroundings.
Importance of Biomechanics in Sports
The study of sports biomechanics is only applicable to people who engage in physical activity, whether it be exercise, sports, or other physical pursuits. Sports biomechanics is the study of forces and how they affect people while they are working out or participating in any sport. Here are a few examples of how biomechanics is used in sport and fitness to improve the performance of athletes or address problems.
- Performance Enhancement,
- Technique Improvement,
- Equipment Improvement,
- Training Improvement, and
- Injury prevention and rehabilitation
Performance Enhancement
The ultimate objective of sports biomechanics is to enhance athletic performance or the health advantages of exercise. By changing the specific training approach and utilizing the equipment a person uses more efficiently, an understanding of biomechanics and applying the mechanical principles can improve a person’s technique and performance. The bones, joints, muscles, and ligaments can be relieved of stress and pressure by understanding how the human body moves. Athletic performance is enhanced as a result.
Technique Improvement
The performance of a sportsperson can be increased by developing their technique. Technique can be improved in two ways by applying biomechanical concepts. First, in order to correct the mistakes made by the athlete and enhance how well they execute a task, coaches may apply their understanding of biomechanics. Second, the athlete might learn a fresh, more efficient way to do a certain sporting maneuver.
Equipment Improvement
The majority of sports use footwear and gear, sometimes known as sports clothes. Wearing the right equipment can help prevent injuries or have a direct impact on performance. Numerous sports also call for the use of equipment other than footwear and clothing. In these sports, lighter and better-designed equipment has enhanced not just the performances of professional athletes but also those of amateur competitors.
Training Improvement
The application of biomechanics offers personalized training changes that are tailored to a person’s capacity and abilities, which helps athletes perform better. Numerous things can cause this. The type of training an athlete needs to improve performance can be determined by the coach by looking at the athlete’s technique flaws.
For instance, the strength or stamina of particular muscular groups, the pace at which the athlete moves, or a particular technique-related factor may all have an impact on how well the athlete performs. For instance, if a gymnast struggles to turn a somersault, the coach might advise that the athlete (a) jump higher, (b) throw his or her arms more vigorously before taking off, or (c) curl up more firmly. These guidelines are all based on biomechanical theory. Javelin, high jump, and cross-country skiing are three sports whose techniques have seen significant alterations in the past.
Injury prevention and rehabilitation
Facilitates the understanding of the human body
The study of biomechanics aids in the comprehension of the entire human body. Understanding biomechanics helps teachers and students comprehend the human body and the different internal and external forces that influence movement. Teachers and coaches learn about the many systems, including the neurological system, muscular system, skeletal system, and others, as well as how those systems interact with one another. As a result, they can teach and instruct a variety of physical exercises and skills that are included in physical education more effectively.
