(HealthDay)—An aerobic exercise program can reduce fatigue in women undergoing radiotherapy for breast cancer, according to a study published in the January issue of the Journal of Clinical Nursing.

Tsui-Yun Yang, R.N., from the National Taipei University in Taiwan, and colleagues assigned 28 consecutive, willing participants with early-stage to an intervention of six weeks of mild- to moderate-intensity aerobic exercise training during their . The next 30 consecutive participants were assigned to routine care without special exercise.

The researchers observed no group differences in baseline fatigue severity, fatigue interference, or hemoglobin levels. There was a significant group-by-time-interaction effect noted for fatigue severity and interference (P ≤ 0.001), with the fatigue severity and interference decreasing significantly over time for women in the intervention group but increasing over time for women in the control group.

"The mild- to moderate-intensity program reduces the fatigue of Taiwanese women with breast cancer undergoing radiotherapy," the authors write.
