Exercise and severe depression: Preliminary results of an add-on study

Background al exercise has been extensively researched as a therapeutic option for treatment of major depression. s andomized controlled trial, we analyze the effects of aerobic physical exercise as an add-on strategy for treatment of severe depressed inpatients. The exercise has a “Dose” of 16.5 kcal/kg/week, three times a week during all the hospitalization. s eliminary results show that there is no significant difference in scores of Hamilton in the second week between groups (Mean[SD] = 8.2[5.96] × 11.18[5.03], p = 0.192). However, there is a significant reduction in Hamilton scores of patients in exercise group at discharge (Mean[SD] = 5.93[4.46] × 9.45[3.56], p = 0.041). Regarding Quality of Life (QoL), no significant difference were found between groups in the second week in physical domain (Mean[SD] = 56.98[8.96] × 54.54[9.18], p = 0.511) and psychological domain (Mean[SD] = 50.88[13.88] × 42.04[12.42], p = 0.106). However, there is a significant difference in psychological domain (Mean[SD] = 55.88[9.92] v 41.66[13.04], p = 0.004) and a trend but no statistical significance in the physical (Mean[SD] = 58.80[9.14] × 52.12[8.70], p = 0.07) at discharge. tions atients receive different treatment strategies, like ECT (1 patient at exercise group × 3 at control group). Other limitation is the small number of participants included until this moment. sion eliminary results suggest that physical exercise could be a feasible and effective add-on strategy for treatment of severe depressed inpatients, improving their depressive symptoms and QoL.
