Boidin M, Handfield N, Ribeiro PAB, et al. - Researchers compared cognitive function in lower-fit (LoFit) and higher-fit (HiFit) obese people with non-obese people, and studied the link between exercise variables (including hemodynamic variables) and cognitive function in obese people. In this study, 54 obese and 16 non-obese people performed maximal cardiopulmonary exercise tests and underwent cognitive testing. Two groups of obese people were defined based on the median aerobic fitness divided by lean body mass (peak VO₂/LBM): LoFit obese (n = 27) and HiFit obese (n = 27) people. The final analysis included 14 non-obese and 49 obese people (HiFit: n = 26; LoFit: n = 23). According to the findings, greater short-term memory and executive function performances were shown by HiFit obese individuals vs LoFit obese individuals, suggesting that aerobic fitness could aid cognitive function preservation, despite the presence of obesity.
