Trial Investigating the Effect of Different Exercise Forms on Depression

During one year, 5-8% of the population will suffer from major depression. Some of the key symptoms are loss of interest in daily activities, loss of energy and sleeping disturbances. The financial consequences of this disease is estimated to be more than 30 million pounds per year in Great Britain and USA alone. There is an increasing interest in the effect exercise has on depression. Smaller studies indicate that exercise is a good treatment for depression. This study will be a large scale randomized trial and will hopefully bring important knowledge on the effects exercise has on depression. We will compare the effect endurance training, weight-lifting exercise and a control group has on depressive symptoms after 4 months training, twice a week.
