Ninety-five participants ages 60–95 yrs. were recruited; however, 5 participants were excluded due to not meeting the inclusion criteria (n = 1), or missing test data (n = 4). Ninety participants (69 females) with a mean age of 75 ± 9.5 yrs. participated in this study. Nearly 58 percent of our population (n = 52) self-identified as white, 12 participants identified as African American, 18 identified as Asian, and 8 self-reported to be from other ethnic backgrounds. Demographic, clinical, and physical performance measures are presented in Table 1. Although males reported completing significantly more years of education (16.7 ± 3.9 vs. 14.5 ± 2.8 yrs.; p < 0.05) and generated significantly greater hand-grip strength (19.7 ± 7.9 vs. 11.9 ± 3.7 kg; p < 0.001) males vs. females, respectively), no other significant differences were found between males and females in our population. Thus, male and female data were pooled for analyses. The cognitive performance measures for all participants are shown in Table 2.
Studies try demonstrated as suggest ± SD for usually marketed data, median (Q75, Q25) to possess skewed data, or letter (percentage) to have categorical analysis.
According to the bivariate analyses, neither BMI (r = ? 0.045, p = 0.676) nor PASE (r = 0.197, p = 0.065) were associated with ranked 3MS performance. However, age (r = ? 0.349, p < 0.001) moderately and negatively correlated with ranked 3MS performance. Distance walked in the 6MWT (r = 0.384, p < 0.001), 6MWT HRTop (r = 0.300, p < 0.004), and peak hand-grip strength (r = 0.297, p = 0.006) were moderately and positively correlated with ranked 3MS performance, and thus were entered into the final model. Table 3 shows the final model which explained 33.3% of the total variance in 3MS scores (R 2 = 0.333, F(3, 85) = , p < 0.001). After adjusting for sociodemographics (age, ethnicity, education) and ?-blocker use, higher 6MWT HRLevel was associated with higher 3MS scores.

Sociodemographic, physiologic, actual overall performance correlates from Creature Naming
Correlations revealed that neither BMI (r = 0.125, p = 0.242) nor peak hand-grip (r = 0.125, p = 0.253) correlated with Animal Naming performance, but age (r = ? 0.355, p < 0.001) was moderately and negatively correlated with Animal Naming test performance. Distance walked in the 6MWT (r = 0.395, p < 0.001), PASE (r = 0.390, p < 0.001), and 6MWT HRTop (r = 0.242, p = 0.022) were moderately and positively correlated with Animal Naming test performance and thus, were entered into the final model. Table 4 shows the final model which explained 32.1% of the total variance (R 2 = 0.321, (F(4, 85) = , p < 0.001). After adjusting for sociodemographics (age, ethnicity, education) and ?-blocker use, PASE independently and positively correlated with Animal Naming performance (p-value = 0.001). Higher levels of self-reported PA on the PASE were associated with better performance on the Animal Naming test. In contrast, ?-blocker use was found to negatively correlate with Animal Naming performance (p-value = 0.035). On average, self-reported ?-blocker users scored 2.1 points lower on the Animal Naming test, compared with non-users.
Sociodemographic, physiological, physical show correlates from TMT A
Correlations revealed that neither BMI (r = 0.070, p = 0.522) nor peak hand-grip (r = ? 0.001, p = 0.996) correlated with log-transformed Trailmaking A performance. However, age (r = 0.411, p < 0.001) was positively, while education level (r = ? 0.356, p = 0.001), PASE (r = ? 0.341, p = 0.001), 6MWT HRHeight (r = ? 0.407, p < 0.001), and distance walked on the 6MWT (r = ? 0.418, p < 0.001) were moderately and negatively correlated with TMT A time to completion. Table 5 shows the final model which explained 25.2% of the total variance (R 2 = 0.252, (F(3, 83) = , p < 0.001). Controlling for sociodemographics (age, ethnicity, education), both PASE scores and 6MWT HRHeight negatively correlated with log-transformed TMT A performance with p-values = 0.017 and <0.001, respectively. This means that higher 6MWT HRTop and PASE scores were associated with a faster TMT A time to completion, or better test performance.
