Abstract
ABSTRACT Aging is a natural process in which physiologically functions decline. Overall, cognitive and functional aspects are intertwined, parameters such as decreased walking speed and impairment of subjective memory may represent health complications, such as motor cognitive risk syndrome. However, the literature lacks evidence on cognitive and functional relationships. Thus, this study aimed to verify the correlation of two levels of muscle power with the cognitive function of community-dwelling older adults. This is a correlational cross-sectional study. The sample consisted of 38 older adults (68±7 years; 81.6% women), assessed for muscle power via the chair rise test, for the assessment of cognitive functions the Montreal Cognitive Assessment (MoCA) was used and adapted versions of the Trails Test A and B (TTA and TTB), animal category verbal fluency test and Stroop test. Spearman’s correlation was used to assess the relationship between the power variable and the cognitive variables. For all analyses, a 5% significance level was established. Our results showed an association of the best power levels with a positive direction for global cognition (rho = 0.35; p = 0.02) and with a negative direction as reading conditions (rho = −0.35; p = 0.02) and Stroop color test (rho = −0.39; p = 0.01). In community-dwelling older adults, higher levels of muscle power are associated with higher global cognition scores and greater agility in the attention involved in reading words and naming colors.

Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
