Is Biking Bad for Your Knees? Research-Based Statistics and Facts
Recent research suggests that biking is generally not bad for your knees and may even protect against knee pain and osteoarthritis.
- A large cross-sectional study of over 2,600 participants in the Osteoarthritis Initiative found that bicyclists had a 17% lower risk of frequent knee pain (RR = 0.83, 95% CI [0.73–0.92]), 9% lower risk of radiographic osteoarthritis (RR = 0.91, 95% CI [0.85–0.98]), and 21% lower risk of symptomatic OA (RR = 0.79, 95% CI [0.68–0.90]) compared to non-bicyclists. The more years spent cycling, the stronger the protective effect.
- A 2020 meta-analysis of 724 knee-osteoarthritis patients showed that stationary cycling reduced pain scores by 12.9 points (WMD = 12.86, 95% CI [6.90–18.81]) and improved stiffness and function versus non-exercisers.
The Direct and Indirect Effects of Cycling on Knees
Direct Effects
Cycling is a low-impact exercise, which means it’s gentle on the joints, especially the knees. When you pedal, you’re not pounding the pavement like you would be when running. This makes cycling a preferred exercise for many, especially those with joint concerns.
The repetitive motion of pedaling can actually help in lubricating the knee joints, reducing the risk of stiffness or arthritis.
Indirect Effects
While cycling itself is gentle, there are other factors related to cycling that can influence the health of your knees:
- Bike Setup: An improperly adjusted bike can lead to poor posture while riding, which can strain the knees.
- Riding Technique: Pushing too hard on high gears or pedaling at a very low cadence can put undue stress on the knees.
- Terrain: Constantly riding uphill or on rough terrains can increase the pressure on the knees.
The Importance of a Properly Fitting Bike
How Bike Fit Relates to Knee Health
Imagine wearing a pair of shoes that are too big or too small. It would be uncomfortable, right? The same principle applies to your bike. If your bike isn’t the right fit, it can lead to discomfort and even injuries. A bike that fits well will allow you to pedal efficiently, maintain a good posture, and reduce the risk of straining your knees.
Risks of Improper Bike Fit
An improperly fitted bike can lead to several issues:
- Knee Pain: If the saddle height isn’t right, it can cause the knees to overextend or remain too bent during the pedal stroke.
- Back Pain: A handlebar that’s too high or too low can make you arch your back or hunch over, leading to back discomfort.
- Wrist and Shoulder Strain: Incorrect handlebar reach or height can strain the wrists and shoulders.
To avoid these problems, it’s crucial to get your bike professionally fitted. This ensures that every part of the bike, from the saddle to the handlebars, is adjusted to your body’s specifications.
Tips for Adjusting a Bad Fit Bike
One of the many reasons why you get knee pain from cycling is a bad bike fit. Any ill-fitting part of the bike can cause pain and could have a long-term effect on your physical health and your bike.
Here are a few subtle changes that you can make that will make a huge difference to your comfort in the bike:
Adjusting your Saddle Height
Getting your saddle height too high or too low will put extra strain on your knees. When your foot is at the base of the pedal stroke, you should feel your knees slightly bent.
To know if you’re doing it right, start pedaling with your heels. If you can’t reach the pedals, your saddle may a little bit too high, but if it’s too easy to pedal and your leg is still bent, then it’s probably too low.
Longer Cranks
According to some experts, longer cranks may be the cause of knee pain. As a rule of thumb, taller riders should use 175mm cranks and shorter riders at 170mm or lesser.
Custom Insole
A custom insole fills the gaps in your foot and the shoe that offers optimal support and comfort. Also, having a custom insole that can help align your leg through the pedal stroke. It can also prevent any types of pain (not only knee pain) and reduce fatigue after cycling.
Possible Causes of Knee Pain
Cycling Longer, Faster and Harder
Suddenly ramping up on your cycling frequency and cycling distance may be the main reason why biking is bad for your knees. Apply the principles of progressive overload in cycling-it involves gradually increasing your riding mileage, time, and cycling frequency per week. Doing it gradually will eliminate the possibility of inflamed joints.
Flicking Your Knee Out
One bad habit you should avoid is flicking your knee out while pedaling. You’re not the only one who does this, it’s a bad habit done even by pro riders! This can usually be seen in the ankle with unstable movement on each pedal stroke.
What exactly is the reason why we flick our knees out while we pedal? One of the reasons cyclists do this is to maintain stability on the saddle. A saddle that’s too high will cause a cyclist’s pelvis to shift from side to side, so their legs flick in and out to stay stable.
One way to avoid flicking your knee out when biking is to improve the stability of your foot-pedal interface to have a much steadier leg when pedaling.
Weak Core
A strong core allows you to have a strong pedal stroke. A weak core will cause you to easily get tired and result in a breakdown in your pedaling mechanics.
A strong leg is not enough to have consistent cycling power, train your core regularly to have more pedaling power and increase your endurance.
Insufficient Warm-Up
A warm-up routine is vital in any sport. Unfortunately, a lot of people do not warm up despite its many benefits.
Warm-up exercises have countless benefits. It improves the oxygen flow in your body, loosens up stiff muscles, and improves your metabolism.
Perform simple warm-ups like stretching your arms, legs, hips, limber, and back before you go on a long ride. Do a simple routine before you go for a ride!
Misaligned Bike Components
Components like pedals and cleats that are not aligned correctly can cause the knees to move inwards or outwards during pedaling, leading to discomfort.
Diagnosing the Cause of the Knee Pain
Anterior Pain
Cause: Overextension during the downstroke, often from a saddle that’s too low or too far forward.
Treating Anterior Knee Pain
Treating your Anterior Knee Pain is very simple and easy. Foam rolling and stretching your legs will loosen off your buttocks, and will release the tension coming from the tightness caused by a bad bike fit.
To increase blood flow in the injured area, you can also apply a Kinesio tape. Cyclists also use Kinesio tape to treat and prevent cycling injuries.
Posterior Knee Pain
Cause: Saddle set too high or too far back, straining hamstrings.
Treating Posterior Knee Pain
Treatment: Lower or move your saddle forward, ice for 5 minutes each hour, and roll calves and hamstrings.
Medial Pain
Cause: Improper cleat placement or excessive pedal “float.”
Treatment: Adjust cleat to allow ~4.5° of float; stretch adductors and apply targeted foam-rolling.
When to See a Bike Physiotherapist
It’s okay to search the internet and ask google what causes your knee pain and how to treat it, but it is crucial to have your knee pain checked by a physiotherapist if you’re already suffering from long-term and consistent pain.
Finally, do not ever self-diagnose and self-treat even if you only suffered a minor injury. Always ask for a medical professional’s advice before doing any home treatments and taking any OTC medicine.
Cycling and Knee Health: The Bigger Picture
Addressing Common Concerns: Is Biking Good for Arthritis?
One of the most frequently asked questions regarding cycling and knee health is its impact on arthritis. Arthritis, an inflammation of the joints, can cause pain and limit mobility. So, is cycling a friend or foe to those with arthritis?
The answer is that cycling can be incredibly beneficial for individuals with arthritis. The low-impact nature of cycling means that it doesn’t put excessive strain on the joints, making it an ideal exercise for arthritis sufferers. However, as with any exercise regimen, it’s essential to consult with a healthcare professional before starting.
The Multifaceted Benefits of Cycling
1. Maintaining Range of Motion: Regular cycling can help in maintaining and even improving the range of motion in the knees. This is especially crucial for arthritis patients, as limited mobility can exacerbate the condition.
2. Injury Recovery: For those recovering from knee injuries, cycling can be a part of the rehabilitation process. The controlled and repetitive motion of pedaling can aid in the healing process, ensuring that the knee regains its strength and flexibility.
3. Muscle Strengthening: Cycling targets the quadriceps, hamstrings, and calf muscles. Stronger muscles provide better support to the knee joint, reducing the risk of injuries and alleviating pain.
Conclusion: Is Biking Bad for Your Knees?
In short, when you ask “is biking bad for your knees,” the answer is a clear no—provided you maintain a proper bike fit, use good technique, warm up wisely, and progress gradually. With those safeguards in place, cycling not only spares your joints but can actually help protect and strengthen them over time.
