Mobility and flexibility are two words often used interchangeably when talking about fitness. But although they both affect how well you move and are connected in some ways, they are not the exact same thing.
Here are answers to common questions about the differences between the two, how they’re connected and ways you can improve both.
What are mobility and flexibility?
Mobility refers to how a joint moves through its normal range of motion. That range of motion varies depending on the type of joint. For example, your hinged knee joint moves backward and forward and can also rotate inward and outward slightly. The ball-and-socket joint in your shoulder makes it possible to lift and lower your arms and move them in a circular motion or back or forth.
Flexibility is the ability of a muscle to stretch temporarily. Think of your muscle like a rubber band – the more flexible it is, the more easily you can stretch it. Although flexibility plays an important role in mobility, it is not that important in and of itself.
What part does flexibility play in mobility?
Flexible muscles help improve how well you can move your joints and that’s why flexibility is an important component of mobility. It’s difficult to move a joint if the muscles and tissues surrounding it are too tight. Tight muscles can pull on a joint, causing it to become misaligned and unstable.
But for good mobility, you also need muscular strength and stability in addition to flexibility. The structure of your joints and surrounding ligaments and tendons can also affect your mobility. Keep in mind that even if your flexibility is good, you can still have poor mobility if other factors that help a joint move are lacking.
Why is mobility so important?
It’s difficult to do many everyday things, from reaching a can on the top shelf at the grocery store to turning quickly to catch a ball, if your joints are stiff or painful and your range of motion is compromised. Injuries are also more common when mobility is restricted.
In addition to avoiding injury and making routine activities easier to perform, good mobility may also help you retain your independence as you grow older. In fact, older adults who had moderate or severe mobility problems were more likely to experience falls or need health care services, according to a study published in Geriatric Nursing.
