Energetic cost of walking

1. Energetic cost of walking predicts cognitive impairment in humans (HR = 1.1, 95% CI 1.00 to 1.20, p = 0.039).

   “Higher baseline cost predicted impairment among adults ≥75 years (hazard ratio [HR] = 1.1, 95% confidence interval [CI] = 1.00 to 1.20, p = 0.039)”

   Humans7.6 ± 3.8 years

2. Cognitive impairment is associated with energetic cost of walking in humans (B = 0.13, p = 0.003).

   “Progressors exhibited a steeper increase in energetic cost than non-progressors (B = 0.13; p = 0.003).”
