Key result
Advanced age is linked to slower heart rate kinetics and higher energy cost during sinusoidal walking.
Why the study?
The influence of age on cardiorespiratory kinetics during sinusoidal walking was not well characterized.
Does age influence cardiorespiratory kinetics during sinusoidal walking in healthy humans?
Cross-Sectional (n=28)
No

p-value: p=<0.05
Aging is associated with slowed heart rate kinetics and increased exercise hyperpnea during sinusoidal walking.
No takes yet. Share an insight, caveat, or question.
Slower HR kinetics and steeper VE/VCO2 slope during variable walking in healthy elderly may signal age-related autonomic shifts; leaves open whether these warrant adjusted exercise testing or further mechanistic study.
Ebine et al. (2018) conducted a cross-sectional in Healthy (n=28). Advanced age vs. Young age was evaluated on Phase shift of heart rate kinetics during sinusoidal walking (p=<0.05). Advanced age significantly slowed the phase shift of heart rate kinetics during sinusoidal walking and increased the energy cost of walking compared to young adults.
