Document Summary
Mechanisms of change: anthropological hypothesis, endorphin hypothesis, monoamine hypothesis, mastery hypothesis, social interaction hypothesis. We are genetically predisposed to be physically active. Technology has progressed so that we no longer have to engage in vigorous activity for our survival. By violating our genetic predisposition by being sedentary, we risk having health problems. During stress (e. g. exercise), the body produces endorphins natural painkillers. More research is needed before firm conclusions can be reached. Effects of exercise on depression are due to altered brain neurotransmitters: serotonin, norepinephrine, epinephrine, dopamine. Neurotransmitters involved in the regulation of emotion. Psychological effects of exercise are derived from accomplishment or mastery felt upon completion of a task. Individuals has a sense of greater self-worth and personal control over the environment. Exercise provides an individual an opportunity to interact with others. This hypothesis may account for part of depression reduction, but it cannot be the sole explanation.
