Abstract

Introduction and objective: The relationship between heat shock proteins (HSP) and physical activity habits has not been studied in depth, which raises the question about the role these proteins play in health. Based on this uncertainty, this study aims to determine whether plasma levels of these proteins are modified according to physical activity habits. Method: Twenty-four blood samples were taken to study HSP concentrations, by ELISA test, and International Physical Activity Questionnaire (IPAQ) was applied to determine physical activity habits. In statistical analysis, were compared HSP means (categorical variables), using ANOVA. Correlation (Spearman) was studied for continuous variables; moreover a multiple linear regression was developed in order to establish the effect of each one of the independent variables In HSP concentrations. Results: For studied sample, not statistically significant differences were found in concentrations of HSP, between active and sedentary subjects; however it was observed that as individuals become more active, levels of HSP are reduced. The correlation between energy expense and concentrations of HSP was not found. In male population, significant differences in concentrations of HSP between categories of physical activity habits (measured in three categories) were found. Conclusion: We propose to keep investigating, since the study suggests that regular practice of physical activity, acts as a protective factor reducing levels of these kinds of proteins in blood.
