Exercise training-induced alterations in skeletal muscle oxidative and antioxidant enzyme activity in senescent rats.

abstract：:Using the indentation method, we investigated the effects of physical exercise (treadmill running 4 km/day for 15 weeks) on stiffness of the articular cartilage in the canine knee. Considering cartilage to be an elastic material with homogeneity and isotropy, we calculated elastic moduli for femoral, tibial, and patel...
