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 […]

The effect of fibroblast growth factor receptor inhibition on resistance exercise training-induced adaptation of bone and muscle quality in mice

Aging in mammals, including humans, is accompanied by loss of bone and muscular function and mass, characterized by osteoporosis and sarcopenia. Although resistance exercise training (RET) is considered an effective intervention, its effect is blunted in some elderly individuals. Fibroblast growth factor (FGF) and its receptor, FGFR, can modulate bone and muscle quality during aging […]

Evaluation of Korean Firefighters’ Fitness Using Candidate Physical Ability Test: Pilot Study

OBJECTIVES The Candidate Physical Ability Capability Test (CPAT) is a complex performance test to assess whether firefighters have sufficient ability to meet the physical demands of firefighting, and is widely used in many countries, especially in North America. In South Korea, however, simple basic physical fitness assessments are still used for firefighters’ fitness evaluation. Here, […]

Differences in salient beliefs associated with voluntary exercise training among South Korean firefighters before and after COVID-19

OBJECTIVES The Candidate Physical Ability Capability Test (CPAT) is a complex performance test to assess whether firefighters have sufficient ability to meet the physical demands of firefighting, and is widely used in many countries, especially in North America. In South Korea, however, simple basic physical fitness assessments are still used for firefighters’ fitness evaluation. Here, […]

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 […]

A Critical Assessment for Sport Management Research: Comparing PLS-SEM and CB-SEM Techniques for Moderation Analysis Using Formative Measures

Historically, researchers in the sport management area have used covariance based structural equation modeling (CB-SEM) when testing complex models. Recently, researchers have been using partial least squares path modeling (often called PLS-SEM) more frequently. The purpose of this paper was to advise sport management researchers about what approach to use by comparing PLS-SEM versus CB-SEM […]

Participation in Sports Activities before and after the Outbreak of COVID-19: Analysis of Data from the 2020 Korea National Sports Participation Survey

The present study aimed to describe the characteristics and rate of participation in sports activities, changes in sports, and the causes of these changes before and after the COVID-19 out-break in Korea using data from the 2020 Korea National Sports Participation Survey (KNSPS). Furthermore, evidence from this study could be used as basic data to […]
