Your body is constantly adapting to the world. If you’re an athlete, your muscles grow to help you move faster and stronger. If you spend a lot of time sitting, your hip flexors will shorten to create more space under your desk so that you don’t need to hunch over it.

And if you go through life doing physical activities, the opposing movements in your joints will strengthen and loosen up as needed. But how does this happen? It all comes down to joint biomechanics. Joints are linked together like pieces of a puzzle, but they’re not all shaped or sized the same way.

Your joints have kinematic chains—the different types of motion they can take part in—and joint ranges—the number of different angles they can bend from within their limits. This article covers everything you need to know about understanding the science behind joint biomechanics: what it is, its importance, and how it affects movement in your body. 

What Is Joint Biomechanics?

Joint biomechanics is the science of how joints work together in your body, from a kinematic standpoint. It’s the study of how motions of various joints are timed and coordinated to create movement in your body. Instead, it looks at how the human body moves as a whole and how joints in different parts of your body work together to make that happen. 

Why Is Joint Biomechanics Important To Movement?

The science behind joint biomechanics is important because it helps you understand how your body moves. Joint biometrics are a key part of movement mechanics, and understanding the science behind them helps you understand how different movements happen and what they do for your body. Joints also get more complicated when you factor in muscles, tendons, ligaments, and whole-body kinematics.

How Does Joint Biomechanics Affect Movement?

Your body is constantly in motion, but understanding how FIX24 Joint Biomechanics affect movement can help you take a step back and see what’s going on. Joints are linked together like pieces of a puzzle, but they’re not all shaped or sized the same way.

The 4 Stages Of Joint Movement

Circular motion is when a joint rotates around its axis while maintaining that axis within a certain radius. Abduction is the motion that happens when one joint moves away from another joint. The difference between these four movements is how much force they use.

Bony Joints 

Bony joints are the most stable type. They include the articulating joints, which make up most of your body’s range of motion. As such, bony joints are better suited for static positions because they don’t require a lot of force to stay in place. The articulating joints are often found in the hands and feet, but they can also be found in between vertebrae or even on your skull.

Synovial Joints 

Synovial joints are the most common type of joints in your body. In synovial joints, there is a fluid-filled sac that fills the joint with a lubricant and acts as an interface between your bones, cartilage, and tendons. Synovial joints have moving surfaces where they come into contact with one another to allow for movement.
