Metabolic Cost of Stair Climbing

Abstract: Metabolic energy costs were determined on sixteen male firefighters ascending a stairmill in an unladen and a laden condition at a vertical velocity of 12.2 m/min. In the unladen condition they wore shorts and tennis shoes, while lagen they wore full protective clothing, including a SCBA, and carried a hose pack. Mean mass of the load was 39.2 kg. Caloric costs were compared with selected equations from the literature. All of the equations overpredicted for the unladen condition. One continued to overpredict, one underestimated, and a third was very close for the cost for the laden condition. An equation derived from data for eight of the subjects, yielded better predictions for the remaining eight, under both conditions, than any of the equations from the literature. Limitations and the need for further research are discussed.

Design and Study of a Stair Climbing Robots with Two Wheels and a “4R+2P” Pattern

Abstract: Aimed at the current major problems of “slipping, misstep and misplace” in the robot stair climbing process and at reaching the goals of being “flexible, adaptive and stable” in multiple scenarios, a two-wheeled robot with a “4R+2P” pattern that can independently climb different structures of stairs is proposed, and a gait pattern for stair climbing through a four-step cycle of “approaching, lifting, putting and retraction” based on this pattern is proposed. Relevant kinematic and dynamic models are established to study the constraint relation. In the experiment, the robot goes up and down different stairs. The simulation and experimental results showed that the two-wheeled robot with a “4R+2P” configuration fundamentally realized up–down stair climbing, adaptive steering and multiscene functions.

Take a message – and take the stairs: Getting to the heart of healthy exercise at work

Abstract: Purpose Worksites have been targeted as an important setting for physical activity interventions. A recent emphasis for health promoters is the use of point-of-choice interventions to encourage stair climbing at work. The purpose of this paper is to explore campaigns to increase stair climbing at work. Design/methodology/approach Focus groups were structured around three messages and four prompts and sought to explore the motivational power of the resources, identify factors contributing to their effectiveness and provide recommendations to improve and optimize content. Benefits and barriers to stair climbing at work were also explored. Findings Health awareness, motivation, social norms and time management influence stair climbing at work. Critically, factors associated with the worksite itself can also bias choice independently of any intervention. Results suggest that messages targeting heart health have the greatest impact on reported propensity to climb the stairs at work. Messages targeting rate of respiration for fitness, however, may have a negative effect, given that most people want to avoid getting out of breath at work. Originality/value Qualitative research is essential for developing and refining the design detail of point-of-choice interventions and tailoring their components to address individuals’ needs in different settings, but there is little evidence of this in practice.

Stair climbing vehicle capable of transporting gas cylinder

Abstract: A stair trolley comprises a trolley base plate (5), a handrail handle (1) connected to the trolley base plate (5), a rear baffle (2) arranged on the trolley base plate (5), and a bearing (3) arranged at the lower part of the trolley base plate (5). The stair trolley is characterized in that cross-shaped wheels (4) are positioned at two ends of the bearing (3), and the bearing (3) is positioned in the middle position at the lower part of the trolley base plate (5). Due to the adoption of the cross-shaped wheels, the trolley base plate (5) is enabled to transport commodities such as gas tank (6) and the like to the upstairs along the stairs (7). The stair trolley particularly suits the residents in a multi-story building without elevator.
