Mitochondrial ROUTINE respiration

1. Mitochondrial ROUTINE respiration is associated with gait speed in humans (β = 0.153, 95% CI 0.028; 0.277).

   “and higher gait speed (β = 0.153, 95% CI 0.028; 0.277).”

1. Mitochondrial ROUTINE respiration is associated with respiratory exchange ratio in humans (β = -0.160, 95% CI -0.300; -0.020).

1. Mitochondrial ROUTINE respiration is associated with fatty acid β-oxidation in humans (β = 0.212, 95% CI 0.049; 0.375).

   “Adjusted regression analyses confirmed the association of ROUTINE respiration with greater fat oxidation (β = 0.212, 95% CI 0.049; 0.375)”
