Relationship between inhibitory control, physical activity, sedentary behavior, and steps volume in physically inactive individuals
Accelerometer, inhibitory control, physical activity, steps per day.
Evidence suggests that physical activity (PA) and sedentary behavior (SB) can be influenced by inhibitory control (IC). A single study to date has investigated the relationship between steps/day and IC. A better understanding of the relationship between IC withPA, SB, and steps/day is crucial for the development of approaches that aim to improve cognitive health through spontaneous PA. Our study verified the relationship between CI withPA, SB and steps/day. This cross-sectional study included 106 participants (33.4 ± 10.37 years; 62.2% women). The levels of PA, SB and steps/day were measured by accelerometry. The IC was obtained from the SCWT computerized test. Categories were created for light physical activity (LPA) (low LPA + high SB, low LPA + low SB, high LPA + high SB and high LPA + low SB), moderate/vigorous physical activity (MVPA) (low MVPA + high SB, MVPA low + SB low, MVPA high + SB high, MVPA high + SB low) and steps/day combined with SB, (steps/day low + SB high, steps/day + SB low, steps/day high + SB high, steps/day high + SB). The Stroop Effect (SE) was associated with MVPA (β = -0.009) and steps/day (β = -1.081). The groups 'Low LPA + Low SB' (β = -181,721), 'High MVPA + Low SB' (β = -463,841) and 'High steps/day+ Low SB' (β = -229,405) had a faster SE compared to groups 'Low LPA + High SB', 'Low MVPA + High SB' and 'steps/day + High SB', respectively. A lower StroopEffect is associated with higher levels of MVPA andsteps/day,and with lower SB.
