The impact provided through treadmills is good for the cartilage within the joint structure. The impact forces synovial fluid to nourishes the cartilage. Also, the impact is great for the skeletal system – helping with bone growth and as well as rid of old bone through the work of osteoblasts and osteoclasts.
However, too much impact could propose issues. Especially if your gait is not in proper alignment.
