Physical activity (PA) is recommended for the management of cancer-related fatigue (CRF), yet the evidence is primarily based on interventions delivered during cancer treatment, with no eligibility criterion for fatigue. The objective of this systematic review was to summarize and evaluate the effect of PA on CRF after cancer treatment (i.e. post-cancer fatigue), using randomized trials where fatigue was an eligibility criterion. Data from 19 eligible studies were extracted by two reviewers. An estimated 7% of all trials on PA for CRF include an eligibility criterion for fatigue after cancer treatment. Sixteen studies were included in a random-effects meta-analysis. Based on studies with substantial heterogeneity and high risk of bias, the effect of PA on post-cancer fatigue was modest and variable (Hedge’s g -0.40; p = 0.010; 95% prediction intervals -1.41 to 0.62). Additional transparently reported randomized clinical trials are needed to better understand the benefits of PA for post-cancer fatigue.

BackgroundSleep disorders are often complained by cancer patients and can last years after the end of therapies, leading to different negative consequences. Non‐pharmacological strategies such as exercise interventions may be considered to counteract this phenomenon. The literature supports the beneficial effects of aerobic training (AT), while evidence on resistance training (RT) is scarce. Accordingly, our systematic review aims to investigate the potential novel effect of RT on sleep outcomes in cancer survivors.MethodsThe literature search was conducted on MEDLINE (Pubmed), Web of Science, Scopus, and Cochrane Central Register of Controlled Trials databases, including only randomized controlled trials (RCTs). The screening procedure was conducted using the web‐based software COVIDENCE. Sleep outcomes assessed through self‐reported questionnaires or objective sleep measurements were extracted from RCTs recruiting cancer survivors of any age and gender, on or off treatment. The risk of bias (RoB) for each study was assessed using the Cochrane RoB 2 tool for RCTs. Meta‐analytic syntheses were performed on sleep quality and insomnia.ResultsA total of 21 studies were included in the review. Considering the mean percentage differences of all studies combined, promising positive results were found after combined aerobic and resistance exercise program (COMB) for sleep quality (−19%) and sleep disturbance (−17.3%). The meta‐analysis results showed significant improvement for both sleep quality and insomnia (d = 0.28, SE: 0.11, Z = 2.51, p < 0.01, 95% CI: 0.07–0.49 and d = 0.43, SE: 0.20, Z = 2.18, p = 0.029, 95% CI: 0.07–0.49, respectively).ConclusionRT interventions of 60 minutes per session, performed 2–3 times a week for 12 weeks, with exercise intensity ranging from 60% to 80% of one‐repetition maximum can be administered to cancer survivors, aiming to improve sleep outcomes.

BackgroundBreast cancer is the most common type of cancer, accounting for 15% of all new cases. Hormone therapy (HT) is extremely effective in reducing breast cancer recurrence. However, adherence to HT medication is often poor due to negative side effects such as fatigue and sleep disturbances. Physical activity has been identified as a possible intervention to improve quality of life and reduce side effects of HT.ObjectiveThe objective of this systematic review was to summarise evidence of exercise interventions for women being treated with HT for breast cancer.MethodElectronic searches were conducted from inception to March 2022 using Medline, SPORTdiscus, Embase, Scopus, PsycINFO and Web of Science databases. Searches included a combination of terms related to breast cancer, exercise, sleep disturbances, fatigue and HT.ResultsTen eligible papers were identified, and their quality was assessed. Type, frequency, duration and intensity of exercise interventions varied. Exercise types included aerobics, strength/resistance training, walking and yoga. Heterogeneity of data made it difficult to draw conclusions. However, aerobic exercise interventions provide clear improvements in fatigue and sleep disturbances.ConclusionsThis review identified a lack of consistency in exercise recommendations for women being treated for breast cancer. It identifies that aerobic exercise can successfully improve fatigue and sleep disturbances, consistent with existing literature. Exercise has a range of benefits for this population, including improving psychological well‐being and quality of life. Clinicians should strongly advocate for engagement in exercise to promote overall physical and psychological well‐being in women being treated for breast cancer.
