    Purpose Resistance exercise training (RET) effectively increases skeletal muscle mass and strength in healthy postmenopausal women. However, its effects on these parameters in postmenopausal breast cancer survivors are controversial or limited. Therefore, the aim of this study was to compare the effects of a 12-week progressive whole-body RET program on skeletal muscle mass, strength, and physical performance in healthy postmenopausal women versus postmenopausal women who survived breast cancer. Methods Thirteen healthy postmenopausal women (HEA, 54 ± 3 years, BMI 26.6 ± 2.7 kg·m2, n = 13) and eleven postmenopausal breast cancer survivors (BCS, 52 ± 5 years, BMI 26.8 ± 2.1 kg·m2, n = 11) participated in the study. Before and after the RET program, evaluations were performed on quadriceps muscle thickness, one-repetition maximum strength (1RM) for various exercises, grip strength, and physical performance. Results Both groups showed significant improvements in quadriceps muscle thickness (time effect, P < 0.001); 1RM strength for leg extension, leg press, chest press, horizontal row, and elbow extension (time effect, all P < 0.001); as well as handgrip strength (time effect, P = 0.035) and physical performance (time effect, all P < 0.001) after the 12-week RET program. There were no significant differences between the groups in response to RET for any of the outcomes measured. Conclusion Twelve weeks of RET significantly increases skeletal muscle mass, strength, and physical performance in postmenopausal women. No differences were observed between healthy postmenopausal women and postmenopausal breast cancer survivors. These findings point out that this study’s RET promotes skeletal muscle mass, strength, and performance gains regardless of breast cancer.

    Food, nutrition and cancer: perspectives and experiences of New Zealand cancer survivors
    (New Zealand Medical Association, 2021-11-12) Peniamina R; Davies C; Moata'ane L; Signal L; Tavite H; Te Morenga L; McLean R
    AIM: This research sought to understand and describe cancer survivors' perspectives and post-diagnosis experiences of food and nutrition, with a particular focus on barriers to healthy eating, health equity, and Māori and Pacific perspectives. METHOD: Data were collected using semi-structured interviews with cancer survivors from three different ethnic groups (Māori, Pacific Peoples, and New Zealand European). Thematic analysis was undertaken to identify both similar and contrasting experiences and perspectives in relation to topics of interest. Data analysis also sought to identify any trends indicating differences between ethnic groups. RESULTS: Limited awareness of the role nutrition has in cancer recovery or prevention, combined with little or no access to nutrition advice/support, meant that healthy dietary change was not a focus for some cancer survivors in this study, whereas others invested considerable time and money accessing nutrition information and support outside of cancer care services. Financial limitations (eg, cost of healthy food and low income) and lack of practical support were also important barriers to post-diagnosis healthy eating. CONCLUSION: There is a need for more widely available cancer-specific nutrition advice and support in New Zealand. Interventions to address financial barriers and increase access to cancer-related nutrition advice and support have the potential to improve cancer outcomes and reduce inequities in cancer outcomes.
