This study aimed to clarify the relationships between loads and gait changes and among gait parameters while walking with various loads. Fifteen healthy young male adults (mean age: 22.1+/-1.6 years) walked with four kinds of loads based on each subject's body mass (0, 20, 40, and 60% of body mass: BM) on his back. Walking speed, cadence, stance time, swing time, double support time, step lengt...

Determination was made of step length, stride width, time factors and deviation in the center of pressure during up- and downslope walking in 17 healthy men between the ages of 19 and 34 using a force plate. Slope inclinations were set at 3, 6, 9 and 12 degrees. At 12 degrees, walking speed, the product of step length and cadence, decreased significantly (p less than 0.01) in both up- and downs...

A rapid, precise and automated means for the regular inspection and maintenance of a large number of tunnels is needed. Based on the depth study of the tunnel monitoring method, the CNU-TS-1 mobile tunnel monitoring system (TS1) is developed and presented. It can efficiently obtain the cross-sections that are orthogonal to the tunnel in a dynamic way, and the control measurements that depend on...

background: owing to increased complexity in the evolution of society, stress has become an important public health problem, and is responsible for more than 30 types of diseases. most of the research on stress conducted to date has focused on physical and psychological aspects; however, there are very few reports about the association between psychological stress and elements within the reside...

In daily life, people seldom walk at exactly constant speeds. Most walking over a day is performed in short bouts [1]. Thus, it is of interest to measure the cost of changing speed. Minetti and co-workers [3] measured the cost of changing speeds but with non-inertial treadmill speed changes or stepfrequency control. Here, we measure the metabolic cost of changing speeds to better quantify the r...

Postprandial hypotension (PPH), a fall in systolic blood pressure (SBP) within 2 h of a meal, may detrimentally affect gait parameters and increase the falls risk in older people. We aimed to determine the effects of postprandial SBP on heart rate (HR), gait speed, and stride length, double-support time and swing time variability in older subjects with and without PPH. Twenty-nine subjects were...

The impact of electronic dipole tags on the walking activity of three insects was determined using video tracking software. Results varied within and between the three species studied. The heaviest tag mounted on the pronotum of the Colorado potato beetle, Leptinotarsa decemlineata (Say), reduced its mean horizontal speed slightly but significantly. The mean horizontal speed of plum curculio, C...

To understand the physical and other factors related to walking among the elderly residents of a Care House for the aged, the total number of steps walked were measured over a period of 1 week (Nov. 6-12. 1994) for 67 female residents (mean age 79 ± 1 years). In addition, walking speed, stride length, and the time to climb 15 steps (stair-climbing time) were measured. To understand the indirect...
