Increased expression of heat shock proteins (HSPs) in response to physical training has been considered one of the mechanisms involved in myocardial protection. Objective: To perform a systematic review on the relationship of physical training on the expression of HSPs in cardiac muscle. Data Sources: We conducted a systematic review of articles published between 2000 and 2013. The descriptors used were: heat shock protein, HSP, exercise, training, cardiac and heart, in english and in the Pubmed database. Results: We found 203 articles, 26 were included for analysis. Data Synthesis: Exercise training increased the expression of HSPs 20, 27, 60, 70, 72, 73 and did not alter the expression of HSP 25. The HSP 90 was changed only by training performed in a cold environment (4 ° C). Conclusion: Physical training is able to increase expression of HSPs in cardiac muscle, promoting cellular protection, increasing protection to the myocardium as a whole.
