To examine stance during the measurement of balance ability, this study aimed to clarify the differences and relationships between balance ability in one-legged (dominant or nondominant leg) and two-legged stances in 25 typical male adults and 25 male soccer players. Balance ability was evaluated with four sway factors: sway velocity, anterior-posterior(More)
This study aimed to compare gait properties during level walking and during stair ascent and descent with varying loads. Fifteen healthy young men (mean age: 22.1 ± 1.6 years) walked while holding four different loads relative to each subject's body mass (0, 20, 40 and 60% of body mass: BM) on their backs. Stance time, swing time, and double support times(More)
BACKGROUND AND PURPOSE Gait properties change with age because of a decrease in lower limb strength and visual acuity or knee joint disorders. Gait changes commonly result from these combined factors. This study aimed to examine the effects of knee extension strength, visual acuity, and knee joint pain on gait properties of for 181 healthy female older(More)
This study aimed to determine the effect of active warm-up by local muscle light exercise and passive warm-up by polarized light irradiation on skin and muscle temperatures and forearm muscle performance (muscle strength, power, endurance, and controlled force-exertion). Ten healthy males performed various grip tests before and after active (local muscle(More)
This study aimed to examine the effect of shoes with a rounded soft sole (Stretch Walker: SW) on gait. Fifteen healthy male (mean age: 23.2) walked under three conditions (SW, Flat-bottomed Shoe: FS, Barefoot: BF). Including walking speed, stance time, step length were selected as temporal-spatial parameters. The angle of hip, knee, and ankle joints during(More)
This study examines the effect of these shoes on the leg joint angle and muscle activity during walking. Ten healthy young male adults (mean age: 24.1±4.3 years) walked on a walkway while wearing one of three kinds of shoes with a rounded soft sole in the anterior-posterior direction (Stretch Walker: SW, mass: 440 g), MBT (Masai Barefoot Technology; similar(More)
Dr. Editors-in-Chief I am submitting a paper entitled " Relationship among gait parameters while walking with varying loads " for publication in the Journal of PHYSIOLOGICAL ANTHROPOLOGY as an original article (Full paper). This is the first submission of this material to any journal. The key point of this paper is that clarify the relationships between(More)
This study compared the effects of barefoot policy, a policy instructing preschool children to go without shoes, on untouched-toes, which do not touch the ground while standing normally, of preschool children attending kindergartens that follow this rule, to preschooler in kindergartens where they must wear shoes, i.e., no-barefoot policy. The study used(More)
Because elderly individuals experience marked declines in various physical functions (e.g., vision, joint function) simultaneously, it is difficult to clarify the individual effects of these functional declines on walking. However, by imposing vision and joint function restrictions on young men, the effects of these functional declines on walking can be(More)
The study compared body-sway characteristics of 380 young adults, 342 generally healthy elderly without disequilibrium disorders, and a group of 33 elderly with disequilibrium disorders. Center of foot pressure (COP) was measured for 1 min. using an Anima's stabilometer G5500 with a data sampling frequency of 20 Hz. Four high reliability measures were used(More)
