Optimization of energy and time predicts dynamic speeds for human walking
eLife, 2023 Humans make a number of choices when they walk, such as how fast and for how long. The preferred steady walking speed seems chosen to minimize energy expenditure per distance traveled.

Framework for Personalizing Wearable Devices Using Real-Time Physiological Measures
IEEE Access, 2023 Personalizing wearable robots by incorporating user physiological feedback can improve energy efficiency and comfort. However, many current personalization methods are specific to a particular device and often require reprogramming, making them less ...

A Fully Soft and Passive Assistive Device to Lower the Metabolic Cost of Sit-to-Stand
Frontiers in Bioengineering and Biotechnology, 2020 Various assistive devices like exoskeletons have been developed to aid the growing number of disabled people. Recent studies have started to explore using soft rather than rigid components to create lightweight and unobtrusive systems that can be more ...

Metabolic cost of human hopping [PDF]
Journal of Experimental Biology, 2017 ABSTRACTTo interpret the movement strategies employed in locomotion, it is necessary to understand the source of metabolic cost. Muscles must consume metabolic energy to do work, but also must consume energy to generate force. The energy lost during steady locomotion and, hence, the amount of mechanical work muscles need to perform to replace it can be

A novel Movement Amplification environment reveals effects of controlling lateral centre of mass motion on gait stability and metabolic cost [PDF]
Royal Society Open Science, 2020 During human walking, the centre of mass (COM) laterally oscillates, regularly transitioning its position above the two alternating support limbs. To maintain upright forward-directed walking, lateral COM excursion should remain within the base of ...

Influences of dynamic load phase shifts on the energetics and biomechanics of humans
Royal Society Open Science, 2023 Using load-suspended backpacks to reduce vertical peak dynamic load exerted on humans can reduce metabolic costs. However, is it possible to further reduce metabolic cost by modulating dynamic load phase shift? If so, is anti-phase better than the others?
