Walking around the preferred speed: examination of metabolic, perceptual, spatiotemporal and stability parameters
منشور في 2024"…Results indicated a significant main effect of speed on all studied variables. While metabolic, perceptual and spatiotemporal values were sensitive to the smallest change in speed (i.e., 0.5 km·h<sup>−1)</sup>, a significant increase in the rate of carbohydrate oxidation and decrease in % fat oxidation were only observed at speeds above PWS. …"
