Network topology of fitness, movement behaviors, and immediate post-exercise systolic blood pressure in older adults (n = 237).

Nodes represent individual variables, and edges represent partial correlations between them. Blue edges indicate positive associations, while red edges indicate negative associations. The thickness and intensity of each edge reflect the strength of the association (i.e., higher weights yield thicker and more saturated lines). All edges represent direct associations after controlling for all other variables in the network. The Fruchterman–Reingold algorithm was used to position nodes such that strongly connected variables appear closer together. Abbreviations: 1. Immediate PESBP, immediate post-exercise systolic blood pressure (mmHg); 2. 6MWT, six-minute walk test in meters; 3. HGS, handgrip strength test in kgf; 4. 30-sSST, 30-second sit-to-stand test in repetitions; 5. MVPA, moderate-to-vigorous physical activity in min/day; 6. Sedentary time, in h/day; 7. Age, in years; 8. Sex, reference group being females; 9. BMI, body mass index in kg/m2; 10. Resting SBP, resting systolic blood pressure in mmHg; 11. AM, antihypertensive medication, reference group being taking antihypertensive medication.
