Moderate Aerobic Exercise May Help Combat Fatigue

Study results indicate that moderate aerobic exercise may improve physical functioning in men who are receiving radiation therapy for localized prostate cancer and this improved physical functioning may be necessary to combat radiation fatigue.

The study involved 66 men who received radical external beam radiation therapy for localized prostate cancer. Half of the men were randomized to an exercise group and the other half were randomized to a control group. The researchers measured fatigue both before and after radiation therapy, as well as distance walked in a modified shuttle test.

The results indicated that the men in the exercise group had no significant increases in fatigue scores from baseline to the end of radiation therapy, whereas the men in the control group had significant increases in fatigue. In addition, the men in the exercise group experienced a significant increase in distance walked in the shuttle test.

The researchers concluded that a program of moderate-intensity walking produced significant improvement in physical functioning with no significant increase in fatigue.
