The study, published online Oct. 14, 2022, by the journal Breast Cancer, involved 89 women ages 32 through 78. When starting radiation therapy — known to lead to fatigue and other burdensome side effects — 43 women were randomly chosen to complete a 12-week, home-based exercise program; the other 46 did not participate in the program. Patients in the exercise group did one or two strength-training sessions weekly, along with 30 to 40 total minutes of aerobic exercise such as brisk walking or cycling.

Researchers used questionnaires to assess the women’s fatigue levels and other quality-of-life measures at four intervals: six weeks and 12 weeks after the study’s start, as well as six months and one year after radiation treatment ended. Women in the exercise group reported significantly less fatigue than their peers while undergoing radiation treatment. Both groups reported improved emotional and physical well-being six months and one year after radiation ended, but only those in the exercise group experienced those improvements as early as six weeks after the study began.
