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

Background Participating in voluntary exercise training is important to meet occupational requirements as well as firefighters' health and safety. The purpose of this study is to identify salient beliefs associated with voluntary exercise training among firefighters in the pandemic era by comparing outcomes with those from a previous elicitation study, which was carried out before […]

Effect of NUTRI-SCORE labeling on sales of food items in stores at sports and non-sports facilities

NUTRI-SCORE is a front-of-pack labeling method that relies of the computation of a nutrient profiling system by reconstructing and presenting nutritional information about food items. In particular, different scores are assigned to harmful (energy, sugars, saturated fatty acids, and salt) and beneficial (proteins, fibers, fruits, vegetables, nuts, rapeseed oil, walnut oil, and olive oil) nutrients. […]

코로나19에 따른 장애인체육회의 비대면 수업 현장반응 탐색과 정책 제안

본 연구의 목적은 코로나19라는 특수한 상황 속에서 장애인체육회의 비대면 수업에 대한 현장 반응을 탐색하고, 비대면 수업을 지속시키기 위한 정책 방안이 무엇인지 파악하는 데 있다. 이 연구는 질적 연구 방법 가운데 하나인 사례 연구(case study)로 진행하였으며 A장애인체육회를 연구대상으로 선정하였다. 그리고 A 소속 프로그램 지도자 3명 및 사무팀장 1명을 연구참여자로 선택하였다. 본 연구의 자료 수집과정은 대면을 통한 […]

e스포츠 활용 중등 방과후 체육 수업에 대한 학생의 학습 경험 탐색

본 연구의 목적은 e스포츠를 활용한 방과후 중등 체육 수업에 대한 학생의 학습 경험을 탐색하는 데 있다. 이를 위해 중학교 방과 후 체육 수업에서 e스포츠를 활용한 축구 수업을 10차시(각 90분)진행하였다. 연구 참여자는 운동 능력과 성별을 고려하여 총 8명(남4, 여4)을 선정하였으며, 면담을 통하여 질적 자료를 수집하여 귀납적으로 분석하였다. 연구 결과, e스포츠를 활용한 체육 수업은 스포츠에 대한 다면적 […]

Application of vibration to the soles reduces minimum toe clearance variability during walking

Selectively Stiffening Garments Enabled by Cellular Composites

Recent efforts on wearable robots have focused on augmenting the motor performance and/or protecting the wearer's body with lightweight structures. However, providing human-scale force and structural stiffness usually conflicts with the wearability. Inspired by sandwich-structured composites with high structural strengths, widely employed in both nature and man-made structures, a mechanism of selectively stiffening garments (SSGs) […]

Artificial neural network model effectively estimates muscle and fat mass using simple demographic and anthropometric measures

Background & aims: Lean muscle and fat mass in the human body are important indicators of the risk of cardiovascular and metabolic diseases. Techniques such as dual-energy X-ray absorptiometry (DXA) accurately measure body composition, but they are costly and not easily accessible. Multiple linear regression (MLR) models have been developed to estimate body composition using […]

Supra-threshold vibration applied to the foot soles enhances jump height under maximum effort

Previous studies have shown that absence or reduction of cutaneous sensory feedback can diminish human motor performance under maximum effort. However, it has not been explored whether any appropriate intervention in the cutaneous sensory input can augment the output motor performance, particularly in motor tasks such as jumping that involve the kinematic chain of the […]

Editorial: Children’s Exercise Physiology, Volume II

After the previous highly successful Frontiers Research Topic “Children’s Exercise Physiology” (2020), we have challenged the academic community to continue exhibiting their main findings in volume II of this topic. In the past edition, the main topics of research were focused on performance, physical fitness, measurement methodologies, motor competence, overweight and obesity, and pathological subjects. […]
