Celeste E Coltman,Gráinne M Donnelly,Hans von Lieres Und Wilkau et al.
Celeste E Coltman et al.
The aim of this study was to explore the association between pelvic floor dysfunction and running kinetics and pelvic acceleration in a cohort of postpartum women. The Australian Pelvic Floor Questionnaire was used to quantify symptom sever...
The Influence of Different Implements on Kinematics and Kinetics Compared to Men's Javelin Throw [0.03%]
不同投掷器械对投掷技术动作影响的生物力学比较研究——与标枪投掷对比
Hans-Peter Köhler,Maren Witt
Hans-Peter Köhler
Javelin throwers cannot safely throw with a long approach run often per training session. Therefore, implements of different shapes and masses are thrown from short run-ups to emulate the demands of achieving high throwing distances. This s...
Can Ground Reaction Force Variables Preidentify the Probability of a Musculoskeletal Injury in Collegiate Distance Runners? [0.03%]
地面反作用力指标能否用于识别大学生长跑运动员的肌肉骨骼损伤风险？
Harper E Stewart,Ryan S Alcantara,Kathryn A Farina et al.
Harper E Stewart et al.
The incidence of lower extremity injuries in collegiate distance runners is ∼20%. Identification of a runner sustaining a potential injury remains challenging. This exploratory, cross-institutional study sought to determine whether ground ...
Navigating Real-World Obstacles: Comparisons to the Traditional Dowel Rod [0.03%]
应对现实世界的障碍：与传统圆木杆的比较
Ashlyn M Jendro,Tiphanie E Raffegeau,Abigail C Schmitt
Ashlyn M Jendro
Historically, obstacle crossing has been studied in a laboratory setting using a dowel rod as a modality to understand how and why individuals trip and subsequently fall. The dowel features several characteristics that are optimal for resea...
Walking While Acting Sad and Happy Emotions Influences Risk Factors of Knee Osteoarthritis [0.03%]
行走时表现出悲伤和快乐的情绪会影响膝骨关节炎的风险因素
Samantha J Snyder,Elizabeth M Bell,SeungJun Oh et al.
Samantha J Snyder et al.
Greater knee adduction moment is associated with increased risk and progression of knee osteoarthritis, and this biomechanical risk factor is modulated through kinematic gait modifications. Emotions are known to influence walking kinematics...
