elings of worthlessness or guilt, indecisiveness, and suicidal thoughts. It is also measured by the BDI in this experiment.ProcedureParticipants will be randomly assigned to one of the three exercise groups, these being the combination group, the aerobic group, and the non aerobic group. The pre-test for depression will consist of the participants filling out the BDI questionnaire. This will asses the state of each participant prior to exercise implementation. The scores of each participant will be recorded by the experimenter. Following the BDI questionnaires, the participants will be assigned to their respective groups. Attendance will be taken at the beginning of each session. The combination of aerobic and anaerobic exercise group will meet four times per week, for a 12 week period. Twice a week, on alternate days, the participants in this group will engage in aerobic exercise. This will consist of a certified aerobics instructor leading a 45 minute class to music. Each session will begin with a warm up of five to seven minutes. This can include walking on the spot, side steps, or anything which is very low impact and somewhat low energy. During each session, a participant will be randomly assigned to wear a heart rate monitor to make it seem as though fitness levels are being measured. It will also be used to make sure that the participants will exercise at a target zone of 70 to 80% of their maximum heart rates. This will ensure that the participants are actually benefiting from the exercise, and not just standing around for the entire class. The fitness instructor will instruct the participants at this time that they should work at a level which feels comfortable for them, and they should not overexert themselves. The next 32 to 35 minutes of the class will be used as the aerobic portion of the class. During this time, the participants will have the option of working at a high , moderate, or low intensity.
