According to the Anxiety and Depression Association of America (ADAA), more than fifteen million individuals have suffered from an episode of depression and more than ten percent of adults will continue to suffer for a lifetime. The study I would like to conduct will determine if exercise can be used as a tool to treating depression. Participants would range from twenty-one to thirty-five and would comprise of both males and females. The program would consist of 60 minutes of aerobic exercise, four times a week over a six-week period. In order to record progress, participants will be given a weekly evaluation in the form of an inventory such as the Major Depression Inventory (MDI) or the Hamilton Rating Scale for Depression. There are a variety of variables that must be taken into consideration in this study. The dependent …show more content…

The inventory to monitor progress is another limitation that if not selected carefully, can inhibit data analysis. A prime example is that MDI or Hamilton Rating Scale may be deficient of specific questions necessary for the study. Finally, factors such as human error and health risks can be attributed to limitations. Error variance are independent of skills or ability but can occur if there were mistakes or miscalculations made. Similarly, increasing a person’s activity from sedentary to more aerobic activity can make he or she more prone to injury if not done at a steady
