Chemotherapy used in the treatment of breast cancer induce alterations in muscle cell protein synthesis that result in muscle weakness. Strength training exercise can alter these effects by increasing lean muscle mass and preventing muscle atrophy. The purpose of this study is to examine the pattern of strength training exercises in women receiving chemotherapy for breast cancer. A physiological framework of chemotherapy-induced cytokines inducing pathological muscle alterations was used to guide this study. 47 women with Stage I-IIIa breast cancer receiving chemotherapy were recruited to a strength training exercise intervention. Data concerning the amount of weight used, number of repetitions and sets of strength training exercises were collected at 4, 8, and 12 weeks of treatment. Data were analyzed using descriptive statistics. At 4 weeks, the mean weight used for upper extremity muscle exercises per week was 5 lbs., mean repetitions = 10, mean number of sets = 2. For the lower extremities the mean weight used was 5 lbs., mean number of repetitions = 9 and mean number of sets = 2. This pattern remained stable at 8 weeks with no noticeable increase in weight load, repetitions or sets done per week. By 12 weeks, weight load increased 2-3 lbs. from baseline for upper extremities, but repetitions and sets remained stable. Lower extremity weight load remained stable, except for quadriceps exercises which increased from 5 lbs. to 7 lbs. lifted. The number of repetitions increased from 10 to 12 and the number of sets performed per week remained stable at 2 sets. Women appeared to be unable to increase weight load lifted over the study period which limited benefits obtained with resistance exercise. However, women were able to maintain the baseline levels of strength training exercises which may prevent deconditioning and functional declines associated with chemotherapy treatment.
