Speed Exponents of Random Walks on Groups [PDF]

International Mathematics Research Notices, 2016
For every 3/4 <= beta < 1 we construct a finitely generated group so that the expected distance of the simple random walk from its starting point is within a constant factor of n^beta. In fact, the speed can be set precisely to equal any nice prescribed function up to a constant factor.

Uphill walking at iso-efficiency speeds

Biology of Sport, 2020
Uphill walking gait has been extensively studied, but the optimal uphill speed able to enhance the metabolic demand without increasing fatigability has so far received little attention. Therefore, the aim of this study was to assess the metabolic/kinematic demand at constant speed (6 km·h-1 G0 level, G2 2% uphill, G7 7% uphill) and at iso-efficiency ...

Walking Speed: The Functional Vital Sign [PDF]

Journal of Aging and Physical Activity, 2015
Walking speed (WS) is a valid, reliable, and sensitive measure appropriate for assessing and monitoring functional status and overall health in a wide range of populations. These capabilities have led to its designation as the “sixth vital sign”. By synthesizing the available evidence on WS, this scholarly review article provides clinicians with a ...

ACLD patients exhibit additional knee kinematic asymmetries at the speed level of healthy subjects

Frontiers in Bioengineering and Biotechnology, 2022
Anterior cruciate ligament deficiency (ACLD) patients tend to walk slowly but try to catch up with the speed level of healthy subjects daily. Exploring the effects of the walking speed level of healthy subjects on the ACLD patients’ knee kinematics is ...

The Relationship Between Walking Speed and Available Walking Height [PDF]

Fire Science and Engineering, 2020
During fire outbreaks, smoke accumulates from the ceiling and reduces the available walking height of people passing through. In this study, a walking experiment was conducted to investigate the relationship between the walking speed of people and available walking height. Twenty-three participants were enrolled.

An exploration of impaired walking dynamics and fatigue in Multiple Sclerosis

BMC Neurology, 2012
Background Physical disability in multiple sclerosis (MS) is frequently characterized by impaired ambulation. Although walking tests have been successfully employed to assess walking ability in MS patients, data analytic procedures have predominantly ...

Valosin‐containing protein counteracts ATP‐driven dissolution of FUS condensates through its ATPase activity in vitro

FEBS Letters, EarlyView.
Biomolecular condensates formed by fused in sarcoma (FUS) are dissolved by high ATP concentrations yet persist in cells. Using a reconstituted system, we demonstrate that valosin‐containing protein (VCP), an AAA+ ATPase, counteracts ATP‐driven dissolution of FUS condensates through its D2 ATPase activity.

Discrepancies in walking speed measurements post-bed-rest: a comparative analysis of real-world vs. laboratory assessments

Translational Exercise Biomedicine
Understanding differences between real-world walking speed (RWS) and laboratory-measured walking speed (LWS) is crucial for comprehensive mobility assessments, especially in context of prolonged immobilization. This study aimed to investigate disparities

Dynamics of Human Walking at Steady Speeds [PDF]

Physical Review Letters, 2004
Biped locomotion is discussed through a Lagrangian formulation for velocity-dependent, body driving forces. An analysis of level walking in humans is given through the known experimental data on the ground-reaction force and the external work without recourse to inverted-pendulum modeling.

Long‐Term Follow‐Up of Chemotherapy‐Associated Biological Aging in Women With Early Breast Cancer

Aging and Cancer, EarlyView.
Women threated with adjuvant chemotherapy for early breast cancer have sustained long‐term increase in p16INK4a,, a robust marker of cell senescence, suggesting a chemotherapy‐associated age acceleration. p16INK4a as well as other biomarkers may identify patients at greatest risk for senescence‐related diseases of aging.
