Objectives: Commuters leaving a station often choose the stair as a quicker exit than the escalator. This paper models the effects of speed leaving the station and stair width on choice of the stairs or escalator.
Methods: Aggregated data from previous studies (n=82,347) revealed a plateau at about 45% stair use as the number leaving each train rose. Subsequently, the time taken by passengers on the stairs and escalator was measured in a station in Birmingham, UK in 2007 (n=5848). The resulting transport rates (passengers s(-1)) for stairs and escalators at the average commuting traffic were used to estimate the effects of increases in stair width on choice of the stairs.
Results: Average transport rates were higher for the escalator (0.93+/-0.33 passengers s(-1)) than the stairs (0.58+/-0.24 passengers s(-1)). Modelling of the effects of transport rate with multiple regression suggested 40.1% of passengers would use the stairs, a figure close to the observed rate. Using similar calculations, a doubling of width of the stairs could result maximally in a 17.2% increase in stair use.
Conclusions: Changes to the width of stairs could produce a permanent increase in lifestyle physical activity immune to the effects of time on healthy intentions.

Movement variability describes an individual's capacity to repeatedly perform motor skills and provides better understanding of coordination during a task. The purpose of this research was to assess the impact that task type and sex assigned at birth have on movement variability and load symmetry in healthy younger adults. It was hypothesized that the between trial variability of peak impact force and average loading rate would not differ between sexes or between tasks (level walking, stair ascent, stair descent, and sit-to-stand) and that load symmetry would not differ between the four tasks for an individual participant using a level of significance of α = 0.

Aging, especially in female, is complex, involving various factors such as reproductive sensitivity, cognitive and functional decline, and an imbalance in the redox system. This study aims to assess the effectiveness of long-term resistance training as a non-pharmacological strategy to mitigate the impairment of recognition memory, hippocampal redox state, and ambulation in aging female Wistar rats during the periestropause period. Thirty Wistar rats aged 17 months, in periestropause, were distributed into non-trained (NT) and resistance training (RT; stair climbing 3 times per week for 4 months) groups.

Capturing human locomotion in nearly any environment or context is becoming increasingly feasible with wearable sensors, giving access to commonly encountered walking conditions. While important in expanding our understanding of locomotor biomechanics, these more variable environments present challenges to identify changes in data due to person-level factors among the varying environment-level factors. Our study examined foot-specific biomechanics while walking on terrain commonly encountered with the goal of understanding the extent to which these variables change due to terrain.

The majority of uranium mill tailing impoundments in the southern part of China are located in humid subtropical regions where persistent rainfall and rapid evaporation of water after rain often occur. Under the prolonged influence of alternating wet and dry conditions, the covering soil layer of uranium mill tailing impoundments develops cracks, leading to the issue of degradation or even failure of the radon retardation effect. A beach surface of uranium mill tailing impoundments in the southern part of China is selected as the research object.
