Statistical society includes 8160, 12-15 year old non-athlete boy students of Babol schools. Random sampling has been used in order to select statistical samples.

Aside from self-confidence, this questionnaire measures five other personal characteristics simultaneously. Two groups answered this questionnaire in two stages: In the first stage, researcherʹs purpose was to specify the reason why thereʹs no preliminary difference between empirical and control groups in terms of their self-confidence mean value (pretest). In the second stage, the purpose was to determine the two groupsʹ self-confidence scale after three months swimming training via the empirical group and to specify the effects of these exercises on the empirical groupʹs self-confidence. Results have been calculated via the T-test using software SPSS19 ( 0.05). results obtained show that considering the effective role of environment in self-confidence and while knowing the important role of self-confidence when facing life pressures, having all the people participate in physical activities and sports increases the self-confidence scale and this in turn helps them take a prosperous step toward a happy and blissful life in terms of their behavior and performance.
