Abstract Recent guidelines recommend exercising ≥ 3 times/week during and after cancer treatment, however treatment-specific barriers may inhibit adherence. We explored the effect of a flexible exercise program on fitness, body composition, and metabolism in a group of recently diagnosed breast cancer patients. Fifty-two females ≥ 18 years with stage I-IIIB breast cancer were instructed to target 2 cardiovascular and strength training sessions/week over 12 weeks, but program length was expanded as needed to accommodate missed sessions. Pre- and post-intervention, we measured: 1) cardiovascular fitness, 2) isometric strength, 3) body composition (dual-energy X-ray absorptiometry), and 4) fasting glucose, insulin, c-peptide, and lipids. Pre-intervention, participants were 53 ± 10 years old (mean ± SD) and overweight (BMI: 27.5 ± 5.4 kg∙m− 2, 40.1 ± 6.5% body fat). Forty participants completed the program over a median 20 weeks (range: 13–32 weeks, median frequency: 1.2 sessions/week). Final workrate during a graded exercise test improved by 13% (10[5–15] W) (delta[95% CI]), and strength increased by 7–9% (right arm: 2.3[0.1–4.5] N∙m; right leg: 7.9[2.1–13.7] N∙m; left leg: 7.8[1.9–13.7] N∙m). Body composition and metabolic markers were unchanged. An exercise frequency of 1.2 sessions/week, while below recommendations, stimulated significant improvements in fitness, and may represent a more realistic target for patients during active treatment.

AbstractAerobic and resistance exercise during and after cancer treatment are important for health-related outcomes, however treatment-specific barriers may inhibit adherence. We explored the effect of lower-frequency exercise training on fitness, body composition, and metabolic markers (i.e. glucose and lipids) in a group of recently diagnosed breast cancer patients. Fifty-two females ≥ 18 years with stage I–IIIB breast cancer were instructed to attend 2 cardiovascular and strength training sessions/week over 12 weeks, but program length was expanded as needed to accommodate missed sessions. Pre- and post-intervention, we measured: (1) cardiovascular fitness, (2) isometric strength, (3) body composition (dual-energy X-ray absorptiometry), and (4) fasting glucose, insulin, c-peptide, and lipids. Pre-intervention, participants were 53 ± 10 years old (mean ± SD) and overweight (BMI: 27.5 ± 5.4 kg m−2, 40.1 ± 6.5% body fat). Forty participants completed the program over a median 20 weeks (range: 13–32 weeks, median frequency: 1.2 sessions/week), over which predicted VO2peak improved by 7% (2.2[0.1–4.4] mL/kg/min) (delta[95% CI]), and strength increased by 7–9% (right arm: 2.3[0.1–4.5] N m; right leg: 7.9[2.1–13.7] N m; left leg: 7.8[1.9–13.7] N m). Body composition and metabolic markers were unchanged. An exercise frequency of 1.2 sessions/week stimulated significant improvements in fitness, and may represent a practical target for patients during active treatment.

The purpose of this investigation was to determine if a structured, home-based exercise program was beneficial to reduce symptoms of chemotherapy-induced peripheral neuropathy and improve quality of life (QOL). A total of 50 women who are breast cancer survivors and are listed in the Breast Cancer Registry of Greater Cincinnati database were recruited by mail. Participants were initially asked to complete the McGill QOL questionnaire and the Leeds Assessment of Neuropathic Symptoms and Signs, before beginning a 10-week home-based exercise program. At the completion of the exercise program, subjects were asked again to complete the same two questionnaires. Pre- and post-intervention data were analyzed using a repeated measures ANOVA, at a significance level of α<0.05. Six individuals completed the investigation. Prior to the 10-week exercise program, participants described their pain as unpleasant skin sensations (Pre-HBEx, N=6), abnormally sensitive to touch (Pre-HBEx, N=6), and coming on suddenly in bursts for no apparent reason (Pre-HBEx, N=5). Following 10-weeks of exercise, participants reported experiencing less of these symptoms (Post- HBEx, N=3, 1, and 4 respectively; P=0.05). It was also determined that troublesome symp- toms were significantly reduced after 10- weeks of home-based exercise (P=0.05).

CONTEXT AND OBJECTIVE: Changes in metabolism have been reported in the majority of patients undergoing cancer treatment, and these are usually characterized by progressive change in body composition. The effects of aerobic exercise programs to combat the cancer and cancer treatment-related side effects, which include the negative changes in body composition, have been extensively reported in the literature. However, few resistance exercise intervention studies have hypothesized that breast cancer patients might benefit from this type of exercise. The purpose of this study was to determine whether exercise protocols that emphasize resistance training would change body composition and strength in breast cancer patients undergoing treatment. DESIGN AND SETTING: Randomized controlled trial, at the Campus Recreation Center and Rocky Mountain Cancer Rehabilitation Institute of the University of Northern Colorado, and the North Colorado Medical Center. METHODS: Twenty inactive breast cancer patients were randomly assigned to a 21-week exercise group (n = 10) or a control group (n = 10). The exercise group trained at low to moderate intensity for 60 minutes on two days/week. The primary outcome measurements included body composition (skinfold method) and muscle strength (one repetition maximum). RESULTS: Significant differences in lean body mass, body fat and strength (p = 0.004, p = 0.004, p = 0.025, respectively) were observed between the groups at the end of the study. CONCLUSION: The results suggest that exercise emphasizing resistance training promotes positive changes in body composition and strength in breast cancer patients undergoing treatment.

Study Population

The aim of this study was to evaluate the effectiveness of an exercise program for the recuperation of the range of motion (ROM) of the shoulder. This is a quasi-experimental study developed at the Mastology Outpatient Clinic of the Federal University of São Paulo - Brazil, from August 2006 to June 2008, with 64 breast cancer patients undergoing surgery. The intervention consisted of: preoperative evaluation of the ROM, verbal and written guidance, demonstration and implementation of the exercises and revaluation at the outpatient follow-up appointments until the 105th postoperative day (PO). From the 7th PO a significant increase was observed in the ROM, which continued until the 105th PO. The minimum time for recovery was 105 days for the women undergoing mastectomy, and 75 days for those undergoing quadrantectomy. There was satisfactory adherence of 78.6% of the women. The domicile program was effective for the recovery of ROM in the study population, benefiting women who can not attend a presential program.
