(College of Physical Education,South China Normal University,Guangzhou 510631,China) Abstract: Heat shock protein is a set of polypeptides with a highly conserved structure,and is also called heat stress protein since almost all organisms will have a heat shock protein expression when they are subject to extra stresses to a certain extent. Heat shock protein gives cells or organisms the abilities to recover from various stresses and protects them from being harmed by these stress factors. Among the abilities above, heat resisting ability has the most prominent performance. As a company of molecules, heat shock protein can maintain the normal structure of cells. Heat shock protein also plays an important role in anti-oxidation and anti-apoptosis. Heat shock protein expression in cardiac and skeletal muscles can be induced by an exercise as well, and is closely related to the form and intensity of the exercise. Heat shock protein expression in skeletal muscle shows in distinctive muscle fibers. Key words: heat shock protein; exercises; cardiac muscle; skeletal muscle; progress of research |
