Is bicycle riding hard on your knees?
605938
no it isn't because you use your calf mucles not your knees. might get a little sore the next day though o and about the grindy sound you hear from your knees, i get it too and it means nothing it is just a little friction between your joints

I think this only happens in rare instances, and than only with people riding every day for long periods of time.  I'd obviously wear cycling shorts/pants that have a thick chamois inside of them.  I know that the banana saddles on road bikes put more pressure on the genitals then a thicker mountain bike style saddle.  I'd avoid one of the firm, ultra-thin saddles designed for racing and move more towards a compromise with cushioning and width.  Do you really care about the extra weight if you aren't in a competition?

I have the same issue:\n\nWhat exercises are the cause of the problem?  If it's running, than walk on the treadmill... up a steep hill.\n\nEven though your knee now hurts, some exercises might not.  For me, the eliptical machine and stationary bike don't hurt.\n\nRemember, when doing leg exercises, you don't want to straighten your knee at any time.  With leg presses, make sure your knee is always slightly bent.  In this way you are  using your larger thigh and calf muscles, and alleviating the strain on your knee.\n\ndon't run!

I am 41, I started to have problems with my knees after my son was born (37). I went to the Doctor for the same problem. He stated in a healthy knee, your knee cap will glide seamlessly across the joint, you have a grove in the center and when your muscular structure begins to  weakening the knee caps will dig new groves. This causes the crunchy, grinding sounds. He suggested to do isometric exercises to improve muscular strength and get it back on track. Hope this helps before you end up in pain as I was when I went to my doctor.

Real riding?  Or just noodling around the neighborhood?\nCycling as an athletic endeavor or mode of transportation utilizes your quads, gluteal group, calves (mostly posterior muscles), hip flexors (tensor fasciae I think), and core muscles (lumbar and oblique muscles need to stabilize the body).  \nThe power generated by a cyclists legs must be directed by equally strong lower trunk muscles.  That's why a professional cyclists will look like a world class athlete from the toes to the obliques.  Then like a mal-nourished accountant from there up.\nAll that said - without a great heart (both actually and metaphorically) nothing else matters.\nCyclists will frequently complain of arm and neck fatigue.  But these muscles are obviously not directly involved in moving on a bicycle.

Jogging is a high-impact form of exercise, so it is rough on your joints in general.  If you can jog on a softer surface like a natural trail or special trails that have a foam like texture, or inside at a fitness center, that might help.\n\nDepending on your age and other factors, this could be a symptom of osteoarthritis, rheumatoid arthritis, or deterioration of the cartilige in your knee.  If it only hurts for a few minutes, I would just try finding a softer surface, or you could consider switching to a lower impact exercise like bicycling.  If it starts to interfere with your daily activity, then you should see a doctor or orthopedic surgeon for advice.

Another yes here! I am always very scared about my knees 'dislocating' or 'popping out' on me. I tend to 'waddle' when I walk and wear shoes with good grip. Just be careful, take your time and if need be, give youself extra time to get from A to B in the snow!

A person has not learnt cycling, if he has not experienced falling while cycling. So don't be afraid of being hit and just continue doing your sports.

Swimming. That's what I did. I have bad knees also, and after swimming, I don't have as many problem. And swimming doesn't hurt them, because you aren't putting pressure on them. I hope your knees get better. Have an awesome day :)

First, adjust the bike to your size. The saddle should be high enough so that when your foot is on the pedal at the bottom of the stroke your knee should be very slightly bent.\n\nSince it is tough to know how the resistance on your particular bike works I can't give you an exact setting. A good rule of thumb is to start each workout at 0 resistance, then gradually increase it throughout the exercise to a point where it is hard- but not impossible- to pedal through the whole rotation, maintaining the same cadence (pedals per minute) for the entire time. \n\nYou should be making about 60 revolutions of the pedals per minute- that is to say that you should determine this using either your left or right pedal since each knee goes up once per rotation. Get it? This is harder to explain than I thought.  \n\nStart to finish you should work out about 30 minutes, or 15 minutes after you start to sweat whichever is longer.\n\nIf your bike includes foot straps, use them. Using an exercise bike is not a "push-push" affair, instead you should be "push pull around and around", trying to power through the entire rotation.\n\nAs you become stronger, I suggest increasing cadence. You'll notice it'll take longer and longer from the time you start until the time you start to sweat so you may want to increase resistance sooner (and higher) as you go along.\n\nOne other thing... if you are doing this to lose weight, you'll likely notice a decrease in size first. Fat has twice the volume of muscle and is about half the weight, so as you add muscle and lose inches you might even see a temporary weight gain.\n\nBe sure to stay well hydrated wit WATER as you work out.\n\nGood Luck!

I have very bad knees, I've already had surgery on one of them for degenerating cartilage. I'm only 20. Before the surgery, I tried physical therapy. In there I found some good stretches, but the most important thing was the discovery that I can use the stationary bike with minimal or no pain. If you decide to do this, keep it at a lower resistance. If it hurts, reduce the resistance. I usually bike on level 2 or so, although bikes differ.

I was diagnosed when I was about 13, and was told to do special excercises to strengthen the tissues around the knee.  I did them a little bit, but I mostly just quit jogging and doing heavy excercising.  I am now 27 and I don't have any problems with it, but I am not very active either.  I also used to wear "CHO-PAT'S" when I would have to run or excercise, they seemed to help reduce the friction.  I started riding the bike a lot more, but I found that even that seemed to aggravate it, swimming was good, but I had to be careful not to kick to hard or my knees would get stiff and achy afterward.  \nMy older brother also had this, and he had to have surgery a couple of times because he didn't slow down in his activies.\nIn short-to answer your question- you should take it easy.  You can still be active, but be careful, and choose your activities wisely, or you may end up having to have surgery.\n(Hope this helped, and good luck!  Don't worry, there are worse problems you could have with your health!  You still have a lot of activity to look forward to.)

pick a gear where you dont have to pedal that hard, you want to use your body weight as a counterbalance...lean back and pull up your handlebars hard...after a few tries you will pedal longer.\n\nif you pull up too hard or lean back to far,your bicycle will flip out from under you..its all about balance...it doesnt come to you overnight but with work and practice you will know how hard to pull up and how far to lean back.

Its like riding a bike

The last answer is good - within a category of bikes (mountain bikes, road bikes) you will always get some that are aligned more to comfort and control (upright and not so stretched forward), and some that are really racy, and designed for out-and-out speed (forward and stretched out).\n\nAerodynamics is only part of the story however. A lot of it is to do with where the riders hips are in relation to the pedals. The less 'bent over double' a rider is, the easier they can breathe, and the more efficiently they can extend their leg muscles. The optimum for conventional style bicycles is around a 90 degree bend between legs and torso.\n\nEven though both of these bikes are designed to go fast, you'll notice that this one (http://www.cervelo.com/bikes.aspx?bike=P3C2006 - the quicker) has the seat further forward in relation to the pedals than this one (http://www.cervelo.com/bikes.aspx?bike=R32006 ).\n\nHope that helps.
