Knee strengthening exercise

  1. Sep 1, 2005 #1
    I've looked through Google and can't seem to find a good site on strengthening the knees. I run a lot on the treadmill so any suggestions are appreciated as well.

    Thank you

    I'd be interested in this as well. After a few k's on the treadmill, I actually start limping, but I'm not in any pain or anything. I wasn't conscious of it for ages until I was at the gym with a friend and when I got off they asked me what was wrong with my knee.

    One technique I used to do is I'd lean my back against the wall in a sitting position and hold that for 2-3 minutes. And do 3 sets of it

    Wow, I just answered my own question. Can I get an award/medal/plaque?

    Maybe not an award, but I'll send you a meat tray. :)

    My knees have benefited since I started step workouts (5 years ago). Stepping is easier on your knees than running (the impact is not nearly as jarring.)

    I use the step twice a week, run once a week, and do traditional aerobics twice a week, including weight training segments for both arms and legs. I've worked up to a lot of weight on the ankles (17 pounds each leg) for the weight portion of the workouts. This buildup was over a two year period, adding another pound every month about. (The weights are because of the "Strong women stay young" books that show how weights benefit bone density for women.)

    I think the "cross training" has benefited not only my knees, but also I don't get shin splints anymore, and my arches are better off than they used to be.

    Step aerobics aren't really en vogue at the moment, but I've benefited from them. I'm sure the weights are responsible for part of the improvement in knee strength, too.

    I have had an arthroscopy on my knee and I can give you the strenghening excercising that I used before and after and continue to do today (about 8 months from the surgery.) Leg lifts may seem like they are a feminine pilates routine, but they actually strengten the smaller stabilizing muscles that one needs in order to endure all the tremendous stresses during running and jumping. Leg lifts can be done by laying flat on the ground, raising one leg up without bending the knee, keeping your toes straight out as if you are pointing at someone in front of you with your toes. Lift the leg about 6-12 inches from the ground until your leg begins to burn, rest for a minute and repeat about 4 times. Perform on both legs.
    Squats are also good, without weights at first and very slowly with control.
    Lunges are also good.
    Isometric strentening (basically holding yourself in a position while your muscles contract.

    A 70 kilogram man walks around 3 kilometers/day. Suppose that a step is 1 meter thus the man is doing 3000 steps/day.

    if he walks with arms crossed on chest thus we have =>

    a knee suffers per day
    3000*70*2 = 420 000 kg/day = 420 tons(*2 because action/reaction)

    if he walks with arm balancing then we have

    3000*70*2*0.5 = 210 000 kg/day = 210 tons(*2 because action/reaction and 0.5 because arms decreases load)

    A single day is far, far from your exercises... :wink:

    Our job is to decrease the load and avoid isometric strengthening that creates osteoarthritis...

    The isometric strenghening that you are speaking of is far different from the one I am speaking of. I believe you are basically talking about avoiding to stand upright. That is different than remaining in an isometric squat position or other stances that promote leg strengthening.

    Studies have shown that isometric contraction aren't anymore on the tune and promote problems.

    I may say that I let down the isometric contraction/squat since...10 years.
