Is running bad for your knees or is it protective? What does the research show?

On one hand, you hear people say that running is high-impact and can be bad for your knees over time. On the other hand, you hear people say that running strengthens your joints and protects bone health. Our bodies were made to move, and running has been proven to provide a range of benefits. Let’s look at the research and see if running is really bad for your knees.

Most health professionals and experts conclude that running isn’t bad for your knees and that it’s actually quite the opposite. There are plenty of science-based benefits of running, including improving your mood, memory, focus, fitness, and blood pressure. Runners can attest to the magic of the ‘runners high’.

What does the research show?

Running is a natural form of movement, and mounting research concludes that frequent running strengthens joints and protects against osteoarthritis in later years. Several recent studies debunk the widespread myth that running is inherently bad for your knees and hips and could compromise your bone health in these joints over time. These studies actually indicate that the opposite is true and that running is protective of knee arthritis.

Runners might complain about knee and joint pain, but arthritis isn’t always the culprit. More common reasons for pain and injury in runners’ knees are patellofemoral pain syndrome (PFPS) and iliotibial band syndrome (ITBS).

The iliotibial band helps with knee stabilization and hip rotation. Iliotibial band syndrome, or ITBS, usually starts on the side of the knees before moving up the thigh and sometimes into the hip. The exact cause isn’t clear, but many coaches and health professionals think it could be due to running with improper form and a lack of collagen and certain nutrients rather than the act of running itself. In the vast majority of cases, physicians treat ITBS with physical therapy and strength training. Running coaches often recommend adjusting your gait and running technique. In rare cases, physicians recommend surgery.

Patellofemoral pain syndrome, or PFPS, typically starts suddenly in the front of the knee. This condition might sometimes be called runner’s knee, but many experts believe it’s more related to weakness in the quadriceps and hamstrings muscles in the thighs. Patella is the word for kneecap, and the condition involves the kneecap moving slightly out of alignment. This condition rarely necessitates surgery, and it’s usually treated with physical therapy and orthotic inserts.

In conclusion

Running isn’t bad for your knees, and most fitness and health professionals believe that other causes are more to blame for knee problems, such as:

  • Lack of collagen and certain nutrients
  • Improper form when running
  • Poor gait
  • Overuse injuries from doing way more than your body can handle

The research shows that running is beneficial for your joint health and could be protective for osteoarthritis over time. 

Tips to protect your knees

Follow these tips to help reduce your risk of knee problems:

  • You can wear protective knee braces from time to time.
  • Take rest days.
  • Stretch before you set off.
  • Make sure you’re running with proper form.
  • Buy the proper supportive running shoes.
  • Consume a nutrient-dense diet.
  • Add other forms of exercise into your routine and boost your quad and hamstring strength.

It’s important that you don’t overdo it and reach a point of burnout. Everyone has their limits. Running is a high-impact activity; rest days are crucial to help your muscles repair and recover. If you’re experiencing a sudden pain, you should consult with your healthcare provider to rule out other underlying causes.

We often hear people say that lifting heavy is bad for your joints over time and increases the risk of injury. Some fitness enthusiasts are recommending higher reps and lower weights instead. So, is it really that simple, and is lifting heavy bad news for your joints? How do you settle on the right weight to still build strength and muscle while protecting your joints? 

Researchers compared high repetitions and low weights with low repetitions and heavy weights in terms of pain, physical function, and muscle strength. Which is the more effective approach to add to a physical therapy program? Let’s check out the research.

If you are starting your fitness journey and don’t have much experience in the gym, it can be unclear as to when you should expect to see results. As a personal trainer, I have worked with numerous clients who thought they could shed that stubborn 20 pounds in just a week or two if they really put in the effort. Unfortunately, it is a bit more complicated than that, and several factors play a role.

So, how long to see results from weight training? Keep reading to find out!

How does exercise boost learning and memory? The power of movement and BDNF
Moving our muscles fuels our brains because it enhances electrical and chemical signals transmitted by nerve cells.

I’ve seen growing research on the benefits of exercise for your brain. Even after a light yoga session or a jog around the block, I can personally attest that I feel more focused and productive, so I’m not surprised by the research that backs it up. Researchers found that individuals who completed more moderate to vigorous exercise had better scores on memory tests. They were also more active in general and spent less time sitting.

Moving our muscles is good for our brains because it enhances neuronal activity, which refers to the chemical and electrical signals generated and transmitted by neurons in our brains. The research continues to highlight this connection along with the benefits of exercise. Let’s explore how exercise boosts BDNF, and how that impacts your brain, learning, and memory.
