is it bad for your knees if you run on grass?

Question

also how are you suppose to breath when you do cardiovascular running?

Answer 1

Although grass absorbs the shock it is uneven gound which causes more shock/strain to your knees.
The worst surface is concrete which is even but does not absorb shock.
The best surface is asphalt. It is even and absorbs shock.

Here is an article from Men's Health on this exact topic:

Answer 2

Running outside causes strain on your knees and joints to begin with. Grass is softer, however if being softer and uneven there is a greater risk of injury.

I Personally run on a flat even road.

As for breathing in through your noose out through your mouth.

Answer 3

I would tend to think that grass would be easier on your knees than running on a completely unforgiving surface such as pavement. However, since grass and dirt have a lot of give, running on it may make you more prone to injury,i.e. rolling your ankle. As for cardio breathing, it's in through the nose, out through the mouth.

Answer 4

Grass is less traumatic on your spine than asphalt, a good padded treadmill is better, and still gives al the CV advantages.

As far as breathing is concerned there is no real trick, if you are gasping it shows how unfit you are. Take is very slowly at first and build up gradually. It will get easier if you persevere.

Answer 5

running on grass or any uneven surface is bad for your joints and leaves you prone to horrendous injury. obviously hard surfaces are bad in there own ways but the right footwear and an efficient running style will minimize the effects of 'road-running'. http://www.posetech.com/pose_method/

as for breathing, well i find that the in through nose out through mouth method to be quite forced, most seasoned runners will tell you that the best way is to just breath naturally, relax your jaw and breath. the key to running is to relax all non essential muscles, tensing your muscles or trying to force a breathing pattern zaps your energy, it is supposed to be fun so relax and enjoy.

Answer 6

i would think not due to the fact that your knees dont have to deal with too much impact from the grass as where they asphalt do
grass and chip trails are the best to run on i find

Answer 7

running cross country will always be better for the skeletal system, joints, etc. than running on pavement or concrete. just make sure that you have the proper footware
