Purpose
Cognitive and physical functions are key factors for safe walking. As these functions deteriorate with age walking may be compromised among older adults. However, cognitive and physical decline may be attenuated with cognitive and physical training. This study investigated the associations between cognitive, especially executive, and physical functions and sex differences in these associations in physically inactive older adults. Additionally, the role of participant characteristics in cognitive and physical training-induced change in executive functions was investigated
Methods
314 older adults aged 70-85 were recruited and randomized to PTCT (N = 155) or PT (N = 159). PT included two supervised training sessions a week and home exercises. PTCT included PT and cognitive training. Measurements were organized at baseline, 6 and 12 months. Physical functions were assessed with 10-meter maximal walking speed, 6-minutes walking distance, dual-task cost in walking speed, habitual walking speed and Short Physical Performance Battery (SPPB). Core skills of executive functions were assessed with Stroop (inhibition), Trail Making Test B (set shifting) and Letter Verbal Fluency (updating). Training compliance was based on participation in supervised training sessions. The data was analyzed with multiple linear regression analyses and longitudinal two-group linear path models.
Results
Mean age of the participants was 74.5. Results showed that Verbal Fluency test was positively associated with faster maximal and habitual walking speed (β = 0.272, p<0.001, β = 0.184, p = 0.009 respectively), longer 6-min walking distance (β = 0.242, p<0.001) and higher scores in SPPB (β = 0.234, p<0.001), additionally, TMT B-A was positively associated with higher scores in SPPB (β=-0.236, p<0.001). No significant sex-differences were found. Additionally, Stroop improved significantly more in women and participants in the low compliance subgroup who received PTCT compared to participant receiving PT (difference -8.758, p = 0.001 and difference in -8.405, p = 0.010 respectively) No other significant associations were observed.
Conclusion
Executive and physical functions are positively associated in older adults. The association depends on the physical task and the executive subdomain. Physical and cognitive training improves older adults’ executive functions. Women and participants who only occasionally engaged in training may gain additional benefits for inhibition from physical and cognitive training compared to physical training.

Lindeman, Katja; Karavirta, Laura; Eronen, Johanna; Kajan, Niina; Portegijs, Erja; Rantanen, Taina (Human Kinetics, 2023)This study aimed to compare community-dwelling older adults’ physical activity (PA) during the COVID-19 restrictions in 2020 to their PA levels 2 years before and investigate associations between earlier physical performance ... -
Multidimensional physical activity profiles and changes in physical function and self-reported walking ability among community-dwelling older adults : a 4-year follow-up
Palmberg, Lotta; Karavirta, Laura; Löppönen, Antti; Hyvärinen, Matti; Rantanen, Taina; Rantalainen, Timo (Oxford University Press (OUP), 2023)Purpose Physical activity (PA) is multidimensional but often assessed using single metrics. We studied how data-driven PA profiles predict changes in physical functioning and self-reported walking ability over time among ... -
