This study aimed to clarify the relationships between isometric squat (IS) using a back dynamometer and 1 repetition maximum (1RM) squat for maximum force and muscle activities and to examine the effectiveness of a 1RM estimation method based on IS. The subjects were 15 young men with weight training experience (mean age 20.7 ± 0.8 years, mean height 171.3(More)
This study aimed to develop a criterion for screening high risk elderly using Demura's fall risk assessment chart (DFRA), compared with the Tokyo Metropolitan Institute of gerontology (TMIG) fall risk assessment chart. Participants included 1122 healthy elderly individuals aged 60 years and over (380 males and 742 females) 15.8% of whom had experienced a(More)
The purpose of this study was to investigate the influence of hypoxic physical exercise on metabolic syndrome (MS) risk markers and high-sensitivity C-reactive protein (CRP) and to compare its effects on preperitoneal fat, arterial stiffness, and several blood parameters related to MS to those of a control group who trained under normoxic conditions.(More)
This study aimed to examine the reliability and sex- and age-related differences of step tests with stipulated tempos as well as to clarify useful test parameters and tempos. One hundred forty elderly people and fifty young adults conducted tapping and stepping tests, matching the tempo provided by a metronome. Both tests involve movements where the subject(More)
This study aimed to examine the performance characteristics of a step test with stipulated tempos, used to evaluate the dynamic balance ability of the elderly, as well as the relationship between this step test and walking ability. Ninety-two healthy older women (age 70.9+/-6.1 yr) who could walk independently, twice performed a 10 m walk at maximum speed(More)
This study aimed to examine age differences in the step test with stipulated tempo, a test of dynamic balance ability in the elderly. One hundred eighty-nine healthy elderly people (96 men and 93 women) executed the step test for 20 s twice, with adjustments of the metronome (40 bpm, 60 bpm and 120 bpm). The knee extension strength of both legs was each(More)
The Purdue Pegboard and Moving Beans with Tweezers test have been used in the rehabilitation of persons with nervous system disorders; however, these two tests differ in their methodology. In the latter test, the testee picks up items with chopsticks or tweezers, but in the former test, the testee grasps items directly with the fingers of one hand. Use(More)
This study examines the effects of fall experience caused by tripping on the movement of stepping over an obstacle. The participants were divided into 3 groups (26 fallers caused by tripping, 24 fallers caused by other causes, and 145 non-fallers). Participants stepped forward over a 10 cm high obstacle with one leg, and then returned to their original(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)
This study examines the effect of obstacle height cognition (OHC) on single-leg forward step (SFS) and Obstacle-SFS. In the SFS test, participants stepped 25 cm forward with one leg and returned it to its original position five times as quickly as possible. The Obstacle-SFS added an obstacle to the above condition in the SFS test. The participants were(More)
