Some met-alloproteinase enzymes are required for the health of the tendon, and others may be damaging, leading to degenera-tion of the tissue. Now researches indicated mechanical loading and cytokines can regulate MMPs expression and activity, and there is a synergetic or inhibitory effect between them. Exercise leads to tendon remodeling, changing its biomechanical, biochemical and structural properties. Key words: matrix metalloproteinases;extracellular marix;tendon remodeling;summary |
