Abstract

The purpose of study was investigate the effects of positive and negative self-esteem manipulation on the variability of cardiovascular performance. This study was an experimental research with pretest-posttest control group design. The research population were composed of the Farhangian university students in the academic year 2013-2014. The sample consisted of 90 subjects (45 males and 45 females) who were selected with random systematic method. To manipulate self-esteem, according to previous studies, subjects individually in three groups of positive and negative manipulation and control groups were participated. Rosenberg scale administered to measure of self-esteem. The multivariate analysis of covariance (MANCOVA) was used to data analysis. Results of experimental study on the manipulation of self-esteem showed that a significant difference p<0/01 between control and experimental groups (positive and negative manipulation). There was no significant difference between groups of men and women. Positive manipulate or enhance self-esteem increased cardiovascular performance and, conversely, negative manipulation or decreased self-esteem significantly reduced cardiovascular performance. The analysis of results showed that the positive self-assessment, has a significantly protective effect in reduction of responses to threats and increase of cardiovascular performance and physical health. Finally turned out the self-esteem and cardiovascular performance has a complex and multidimensional relationship.
