Key result
Cancer treatment (radiation or chemotherapy) predicted differences in reaction times on the 1-back working memory task compared to age-matched controls (p=0.029).
Why the study?
Do cardiorespiratory fitness, heart rate recovery, and physical activity affect working memory in breast cancer survivors compared to age-matched controls?

May support promoting fitness to aid working memory in survivors; extends associations but leaves causal benefits open.
Case-Control (n=62)
Do cardiorespiratory fitness, heart rate recovery, and physical activity affect working memory in breast cancer survivors compared to age-matched controls?
p-value: p=0.029
Higher physical activity, cardiorespiratory fitness, and faster heart rate recovery are associated with better working memory in both breast cancer survivors and healthy controls.
MacKenzie et al. (2015) conducted a case-control in Breast cancer (n=62). Breast cancer treatment (radiation or chemotherapy) vs. Age-matched women with no previous cancer diagnosis was evaluated on Reaction times on the 1-back working memory task (p=0.029). Cancer treatment (radiation or chemotherapy) predicted differences in reaction times on the 1-back working memory task compared to age-matched controls (p=0.029).
