Objective: To determine the relationship between domain-specific physical activity (PA) (e.g., occupational PA [OPA], transport-related PA [TPA], and recreational PA [RPA]) and cognitive function in older adults. Methods: The data was obtained from the 2011-2014 cycle of the NHANES. We utilized weighted multivariate linear regression models and restricted cubic spline (RCS) among the included 2924 people aged 60 years or older for our purposes. Results: RPA and total PA according to WHO guidelines were associated with verbal fluency (RPA β: 1.400, 95% CI: 0.776, 2.024, p=0.002; total PA β: 1.115, 95% CI: 0.571, 1.659, p=0.001), processing speed and executive function (RPA β: 2.912, 95% CI. 1.291, 4.534, p=0.005; total PA β: 2.974, 95% CI: 1.683, 4.265, p<0.001) were positively correlated, and total PA was correlated with delayed memory performance (β: 0.254, 95% CI: 0.058, 0.449, p=0.019). There was a non-linear relationship between the amount of PA and cognitive function (p for non-linear <0.05), with the best results at 600-1200 MET-minutes per week. No significant association was observed between OPA, TPA, and various aspects of cognitive function among individuals over 60 years. Conclusion: there was no noteworthy correlation discovered between OPA and TPA in relation to cognitive function. However, RPA and total PA exhibited significant associations with verbal fluency, processing speed, and executive function.Additionally, maintaining PA levels ranging from 600 to 1200 MET-min/week would yield the most favorable outcomes for cognitive function.
