Many people like to run on treadmills. It is easy and can be done anytime. But some ask, “Can running on a treadmill hurt my knees?” This question is important. Knees are very important for running and daily life. If your knees get hurt, you may stop running or feel pain when you walk.
How Does Running Affect Your Knees?
Running is a good exercise. It helps your heart and body. But it also puts pressure on your knees. When you run, your knees carry your weight. They also absorb the shock from each step.
Sometimes, this pressure can cause pain or injury. But it does not mean running is bad. It means you need to be careful. How you run and where you run can change the effect on your knees.
Is Running on a Treadmill Different from Running Outside?
Many people think running on a treadmill is softer. It may be true. Treadmills have a smooth and flat surface. This surface can absorb some shock. Roads or sidewalks are hard and can hurt knees more.
But treadmills also have downsides. You run in the same place all the time. This may cause repetitive stress on your knees. Outside running changes your steps a little. It helps use different muscles.
What Can Cause Knee Pain from Treadmill Running?
Not all treadmill running hurts knees. But some things can cause pain. Here are some common reasons:
- Wrong running form: If you run with bad posture, your knees may hurt.
- Too much running: Running too long or too fast can strain knees.
- Wrong shoes: Old or bad shoes do not support your feet well.
- Hard treadmill surface: Some treadmills are not soft enough.
- Pre-existing knee problems: If your knees were hurt before, running may make it worse.
