Key result
Young persons with Down syndrome demonstrated greater amplitude of low-frequency oscillations and lower approximate entropy in force output compared to age-matched controls (P<0.05).
Why the study?
Does Down syndrome alter the complexity and variability of force output during static exercise compared to healthy young and older adults?

Force output patterns in young Down syndrome resemble older adults; hypothesis-generating for premature aging effects on motor control.

Does Down syndrome alter the complexity and variability of force output during static exercise compared to healthy young and older adults?
p-value: p=<0.05
Young persons with Down syndrome demonstrate force output variability and complexity similar to older adults without Down syndrome, suggesting a link between premature aging and less complex force output.
Heffernan et al. (2009) conducted a cross-sectional in Down syndrome (n=88). Down syndrome vs. Healthy young and older individuals was evaluated on Magnitude and structure of force output variability (mean, SD, CV, spectral power, and approximate entropy) (p=<0.05). Young persons with Down syndrome demonstrated greater amplitude of low-frequency oscillations and lower approximate entropy in force output compared to age-matched controls (P<0.05).
