Abstract/Description: Breast cancer survivors (BCS) encounter side effects from cancer treatments that reduce muscular strength. Studies show resistance training (RT) in BCS can improve strength. One concern with RT in BCS is increasing lymphedema, which is swelling of the arms from lymph node removal and is a common side effect in BCS. Studies suggest low to moderate RT may improve or reduce the risk of developing lymphedema. PURPOSE: To evaluate the efficacy of a moderate to high intensity RT intervention to improve muscular strength and lymphedema in BCS over a 12-week period. METHODS: Thirty-three (age: 59±8yrs; BMI: 27.2±5.6kg/m2) BCS were measured pre and post training for muscular strength (chest press and leg extension) via one-repetition maximums (1-RM) and handgrip (HG) strength via a HG dynamometer. Lymphedema was monitored at baseline and weeks 5 and 9 by measuring the percent difference in circumference between the involved and uninvolved arm. A positive percent difference indicates the possibility of edema. RT consisted of two days/wk using ten exercises performed for three sets of 10-12 repetitions at ~65-85% of 1-RM. ANOVAs were used to analyze data. Significance was accepted at p<0.05. RESULTS: BCS significantly increased upper (86±22 to 115±29kg) and lower body (97±25 to 116±31kg) strength and HG strength (51±9 to 54±8kg). The average percent difference in upper extremity volume of BCS significantly decreased from 5.6±11.2% at baseline to 2.0±5.6% in week 9. CONCLUSIONS: Twelve weeks of RT at 65-85% of 1-RM was well tolerated and significantly improved muscular strength and decreased lymphedema in BCS.
