The purpose of the current study was to investigate whether adaptations of stride length, stride frequency, and walking speed, independently influence local dynamic stability and the size of the medio-lateral and backward margins of stability during walking. Nine healthy subjects walked 25 trials on a treadmill at different combinations of stride frequency, stride length, and consequently at di...

The performance of subjects walking blindly to previously inspected visual targets (located at 5, 10 or 15 m from the subjects) was studied in 2 experiments. In Expt. 1, subjects selected as good visual imagers were instructed to build up a mental representation of the target. Then they had to either actually walk or imagine themselves walking to the target. Walking time was measured in both th...

BACKGROUND Slow walking speed in elderly people predicts increased morbidity and mortality. We examined factors that may be associated with decreased habitual walking speed in older men and women. METHODS Older (range: 60-88 years, mean = 72.5 years) men (n = 25) and women (n = 24) were recruited. The Short Physical Performance Battery, body composition, VO(₂peak) on a treadmill, VO₂ and rate...

The aim of this study was to investigate the validity of the ActiSmile (AS), a physical activity feedback device. Twenty-five participants (age: 36.5 ± 14.3 y) performed nine different activities including standing, running, cycling, playing badminton, sweeping the floor with a broom, and several types of walking for 3 min 25 s each. Each participant received two AS devices, one attached at the...

OBJECTIVE To determine whether the walking speed maintained during a 1 km treadmill test at moderate intensity predicts survival in patients with cardiovascular disease. DESIGN Population-based prospective study. SETTING Outpatient secondary prevention programme in Ferrara, Italy. PARTICIPANTS 1255 male stable cardiac patients, aged 25-85 years at baseline. MAIN OUTCOME MEASURES Walking...

OBJECTIVE The objective of this study is to examine the influence that visuospatial cognitive tasks have on gait function during DT treadmill walking, and as a function of age. Conversely, to examine the influence that walking has on executive functions involving visuospatial processing. METHODS Twenty-five young (26±6.1years) and 25 older adults (76±3.9) performed different types of computer...

A superconducting linear accelerator operating in continuous-wave mode could produce X-ray free electron lasers (XFEL) at megahertz repetition rate, with the capability that delivering wide spectral range coherent radiation to multi end stations. In this Letter, energy recovery Linac (ERL) is proposed flexibly control beam for a Linac. Theoretical investigations and multi-dimensional numerical ...

The effectiveness of security and accessibility to all facilities supplied in the neighborhood area was evaluated using Pedestrian Infrastructure Quality Service methodology. method is known as a "mix land uses test pedestrian connectivity," it encompasses use connectivity within 400-meter walking radius, indicated on map. According findings, 28% pedestrians age range 25–34 years old were eager...

When a Hamiltonian system undergoes stochastic, time-dependent anharmonic perturbation, the values of its adiabatic invariants as function time follow distribution whose shape obeys Fokker-Planck equation. The effective dynamics body's centre-of-mass during human walking is expected to represent such stochastically perturbed dynamical system. By studying, in phase space, vertical motion 25 heal...
