During the course of the study, women in the weightlifting group experienced fewer exacerbations of their condition, and a reduction in symptoms compared to the women who did not lift weights. There were 19 women in the control group who experienced lymphedema exacerbations that required treatment from a physical therapist, compared to 9 in the treatment group. The proportion of women who experienced an increase of five percent or more in their limb swelling was similar in both groups -- 11 percent of the weight-lifting group and 12 percent in the control group. The researchers theorize that a controlled weightlifting program may have protective benefits, by boosting strength in affected limbs enough to ward off injuries from everyday activities that can aggravate lymphedema symptoms.

???Our study shows that participating in a safe, structured weight-lifting routine can help women with lymphedema take control of their symptoms and reap the many rewards that resistance training has on their overall health as they begin life as a cancer survivor,??? Schmitz says. ???We did the intervention in community fitness centers deliberately, in the hope that positive results seen in our study would continue to be available to breast cancer survivors long beyond the end of the research study.???

It is recommended that women start with a slowly progressive program, supervised by a certified fitness professional, in order to learn how to do these types of exercises properly. Women with lymphedema should also wear a well-fitting compression garment during all exercise sessions. The new research was conducted in partnership with YMCAs in Philadelphia, Montgomery and Delaware Counties in Pennsylvania and in Burlington County in New Jersey, as well as Sisters-In-Shape Fitness in Philadelphia. Staff at the Edison-Metuchen YMCA in New Jersey have also been trained to deliver this intervention.

The research was supported by grants from the National Cancer Institute and the National Center for Research Resources.
