A scoping review of studies exploring physical activity and cognition among persons with cancer

Relationship of physical activity and cognitive functioning among breast cancer survivors: a cross-sectional analysis

“…While several of the analyses were exploratory and hypothesis generating in nature, the rigorous measurements of this study using an objective measure of physical activity and both self-reported and objective measures of cognition provide important contributions to the literature. The different results for objective and self-report cognition found in the current study are consistent with previous research (Koevoets et al, 2022;Brunet and Sharma, 2023;Tometich et al, 2023) and support the need for measuring both (Pullens et al, 2010;Hutchinson et al, 2012). Self-report is important in that it reflects the concerns, distress, and experience of the person.…”

“…Consistent with our primary hypothesis and previous research, better self-reported cognition was associated with greater minutes of physical activity (Campbell et al, 2020;Brunet and Sharma, 2023;Jesús et al, 2023). This relationship is important as many women decrease their activity levels during and after breast cancer treatment (Howard-Anderson et al, 2012) and continue to have lower levels of PA than similar women without cancer (Tai et al, 2012;National Cancer Institute, 2019).…”

“…Understanding what aspects of cognition are related to activity, and when and who would most benefit from physical activity is still unknown (Meattini et al, 2017;Campbell et al, 2019;Erlenbach et al, 2021;Haggstrom et al, 2022;Brunet and Sharma, 2023;Franco-Rocha et al, 2023;Jesús et al, 2023). Therefore, the primary aim of the current analyses was to test the relationship between self-reported cognitive abilities and objectively measured processing speed with accelerometer measured moderate to vigorous physical activity (MVPA).…”

“…While both chemotherapy and endocrine therapy have individual impacts on cognitive function, a recent prospective study in breast cancer survivors found no incremental deterioration in the presence of both therapies (Mandelblatt et al, 2016). A growing research literature demonstrates the benefit of physical activity for CRCD, however some results have been discrepant in part due to variations in how both cognition and activity are assessed (Brunet and Sharma, 2023).…”

“…The existing research on the relationship between cognition and exercise for breast cancer survivors has lacked consensus, the strongest evidence remains with the relationship between selfreported cognition and processing speed (Marinac et al, 2015;Campbell et al, 2019;Brunet and Sharma, 2023). Although selfreport and objective measures of cognition are often not related, both measures capture important aspects of cancer survivors experience (Tannock et al, 2004;Bender et al, 2008;Hutchinson et al, 2012).…”
