Soreness & Mobility
You may have noticed athletes wearing strips of tape around their ankles, knees or shoulders. What's it all about—and should you try it out, too?

If you've dealt with an injury, visited a physiotherapist, or even just watched a professional game or race, you may have seen kinesiology tape—those popular strips of tape donned by athletes in all sports.
Why is the tape so popular? "K-tape's magic is in its elastic structure", says Alina Kennedy, CSCS, certified running coach and physiotherapist. "When you apply it, you stretch the tape, which then causes it to pull back on itself slightly and produce wrinkles in the skin. The theory is that as the skin bunches up, it increases blood and lymphatic flow underneath it. This is great for injuries because it encourages more healing and faster recovery".

When kinesiology tape pulls on your skin, it creates a very small amount of space between your skin and the tissues that lie just underneath, and not only does that aid with more blood and lymph flow as Kennedy describes, it also gives your joints more room to move.
For example, one study found that taping around the knee can increase the patellofemoral joint space. Even though the space is small, it can be enough to reduce joint irritation during movement.
There's a mental component as well, Kennedy says. K-tape gives a particular body part a sense of extra support, whether that be your ankle, knee or something else. Even though it won't change how you move, the sensation of having tape around a joint can give you the feeling that you have an extra bit of stability, Kennedy says.
In her practice, Kennedy often uses K-tape for muscular injuries like Grade 1 muscle strains—mild damage with minimal loss of strength and motion—in calves, hamstrings and quads. She's also found it works well for runners who experience muscle fatigue and leg cramps during long-distance runs or races.
The tape is also useful when retraining weakened or imbalanced muscles. For example, a 2017 randomised controlled trial that looked at participants with forward head posture, which can cause pressure on the cervical spine. Results showed improvements in head placement when they used the tape on their necks and upper back.
Even if you don't have pain, asking a professional to apply the tape first can be helpful, says Whitney Heins, certified running coach and founder of US running community The Mother Runners. That way, you can get advice on placement and detailed instructions, making it easier for you to apply it on your own.
If you're hoping to use the tape for a big game or race, Heins suggests having a licensed professional apply it a day or two ahead of the event—the tape will still be in place days later, and you'll know how to reapply if necessary.
Whatever your goal or need, K-tape application should follow these guidelines:
And remember, "While helpful in managing pain in some athletes, it's definitely not treatment and won't 'fix' any injury", Kennedy says. "I'd recommend that if you're in pain, you should get your injury assessed by a physiotherapist or sports doctor prior to using K-tape".
Look at any race starting line, and you'll see several ways to tape a knee, because there's no one "right" way, Kennedy says. Play around with what feels most stable to you and work with a physiotherapist to determine the application that best addresses your needs.
The easiest method is to buy pre-cut kinesiology tape specifically for the knee. This is called a Y-strip, as it looks like an extra wide piece of tape that's partially cut in the middle.

If you have stiffness, mild pain or instability in your ankle, taping can help, Kennedy says, as long as there isn't an actual injury. Here are the steps for taping:
Although this is the same way you'd tape a sprained ankle to keep it stable while it's healing, that doesn't mean you're ready to get back to your sport because you have the tape on. The tape is meant to enable joint mobility while you're getting better—not get you back into action straight away. This goes for any type of injury, including a meniscus or rotator cuff tear.
Check with your doctor about the time frame for a return to exercise if you have a sprain, strain or other injury.
