Research Regarding the Growth of Self Trust with the Help of Strength Exercises for High School Students

This research attempts to show that strength exercises using weights and different practices change the body structure by lowering the percentage of passive mass and raising that of active mass. The actual work for this and its outcomes change the image about the self and the others, modify the ideal of life, the motivational structure and implicitly the emotional behavior bound for emotional stability. An individual's personality is the expression of his/her individuality, and its content consists of neuropsychological characteristics showing two essential features, generality and permanence, and they characterize the entire life of a person. Some of the most general features are dominant and permanent, and they control the group of the central and secondary features, which are characterized by low generality. The elements composing the personality are interrelated and made by the self, the superego and the ego. The self-image is the materialization of a person's vision about him/herself, and its development supposes a subjective construction. (C) 2014 The Authors. Published by Elsevier Ltd.
