Exploring the eating-out experience of people with vision impairment in Korea

This study aims to explore the eating-out experience of people with vision impairment (VI) with the persona method. People with VI are not privileged with information due to limited accessibility. Previous studies have suggested kiosks are the main barrier in the eating-out experience of people with VI. However, the quality of the experience of people […]

남자 중학생들의 이동능력 특성과 학생건강체력 요인의 상관관계

본 연구는 남자 중학생 51명을 대상으로 학생건강체력평가(PAPS) 기반 체력요인과 이동능력 특성(보빈도, 보장, 보폭, 외 발지지기, 양발지지기, 발 이지 시점, 내/외반 가동범위, 배/저측 굴곡 가동범위, 내/외전 가동범위, 기저면, 중력중심) 간 상 관성을 분석하여 변인 간 세부적인 관계성을 갖는지 알아보았다. 근지구력과 심폐지구력이 이동능력 특성과 높은 상관성 을 보였고 근력, 순발력, 유연성도 낮지만 유의한 상관성을 보였다. 본 연구를 […]

Decoupled control of grasp and rotation constraints during prehension of weightless objects

Gravity provides critical information for the adjustment of body movement or manipulation of the handheld object. Indeed, the changes in gravity modify the mechanical constraints of prehensile actions, which may be accompanied by the changes in control strategies. The current study examined the effect of the gravitational force of a handheld object on the control […]

The Effects of External Vibration on Coordination Strategies of Multi-Muscles during Voluntary Isometric Torque Production

PURPOSE To investigate the effect of muscle vibration on performance accuracy and multi-muscle coordination pattern during voluntary isometric knee extension torque production. METHODS The subjects were tested under two conditions of external vibration frequencies (90 Hz vibration (VIB)&no-vibration (NVIB)) with three levels of torque magnitudes of 20% (MVT20), 40% (MVT40), and 60% of maximal voluntary […]

Muscle fiber type-dependence effect of exercise on genomic networks in aged mice models

Skeletal muscles are made up of various muscle fiber type including slow and fast-twitch fibers. Because each muscle fiber has its own physiological characteristics, the effects of aging and exercise vary depending on the type of muscle fiber. We used bioinformatics screening techniques such as differentially expressed gene analysis, gene ontology analysis and gene set […]

Reliability and Validity of the Kinect-Based Mixed Reality Device: Pilot Study

OBJECTIVES Firefighter (FF) is an occupation which needs high fitness abilities. However, most of Korean FFs in the capital city have relatively low fitness levels and they have difficulty participating in exercises owing to their emergency environments. Kinect-based mixed reality device (KMR) is a device that can deliver exercises with live visual feedbacks by detecting […]

Differences in Blood Pressure and Obesity According to the Physical Fitness Level for Korean Older Persons: Considering Data from the National Fitness 100

PURPOSE High blood pressure and obesity pose significant health problems for older individuals. Previous studies showed that regular exercise improves physical fitness factors and decreases blood pressure and obesity. Therefore, this study investigated differences in blood pressure and obesity according to the physical fitness level of Korean older individuals using the National Fitness 100 data […]
