Acute prolonged exercise evokes various physiological stresses that can stimulate the release of extracellular HSP70. However, exercise-induced extracellular HSP70 responses are inconsistent in human studies. Therefore, the purpose of this meta-analysis and meta-regression was to systematically evaluate the effect of exercise on plasma HSP70 expression and to determine the exercise-associated factors contributing to plasma HSP70 response. Data were extracted from 26 experimental trials from 13 studies, including 154 participants, in which plasma HSP70 was measured before and after prolonged, continuous running or cycling exercise at a fixed intensity relative to V\u0307o\n                    <jats:sub>2max<\/jats:sub>\n                    .
