Traumatic knee injuries and career drop-outs in adolescent competitive alpine skiers aged 15–19: a longitudinal 4-year follow-up study examining rates, biomechanical injury risk factors and potential reasons for quitting Open
Between 15 and 19 years of age, one-third of competitive alpine skiers suffer from traumatic knee injury and more than half of skiers end their sports careers. In female skiers, stiff landing strategies may be considered an important but m…

Posterior Tibial Slope Characteristics and Their Relationships With Thigh Muscle Morphology, Activation Patterns, and Dynamic Knee Valgus in Male and Female Soccer Players Before and After Fatigue: A Descriptive Laboratory Study Open
Background: Soccer players are at high risk of anterior cruciate ligament injury as well as reinjury, with higher rates in women and in the supporting leg, and fatigue impairs the neuromuscular control of the knee joint. However, little is…

Shape factor versus truncated cone‐based quantification of quadriceps and hamstring muscle volumes—A choice between accuracy and precision Open
This study aimed to determine the average location of maximal anatomical cross‐sectional area of the quadriceps and hamstrings and to investigate the agreement of different muscle volume estimation methods. Magnetic resonance imaging datas…

Hamstrings and quadriceps muscle size and strength in female and male elite competitive alpine skiers Open
Competitive alpine skiing requires a high level of physical fitness to perform sport-specific manoeuvres and to minimise the risk of injury. The aim of this study was to establish reference values for the maximal anatomical cross-sectional…

Longitudinal Assessment of Intersegmental Abnormalities in the Lumbar Spine of Adolescent Competitive Alpine Skiers Over 48 Months Open
Background: Overuse-related intersegmental abnormalities in the spine of competitive alpine skiers are common findings. However, longitudinal changes in intersegmental abnormalities and symptoms throughout adolescence have not been assesse…

Greater hip internal rotation range of motion is associated with increased dynamic knee valgus during jump landing, both before and after fatigue Open
Purpose The aim of this study was to analyse sex‐specific differences contributing to dynamic valgus in competitive soccer players before and after a standardised fatiguing protocol. Methods Thirty‐nine healthy female and male competitive …
View article: Changes in patellar tendon complaints and shear wave velocity patterns among competitive alpine skiers during a 4-year post-growth spurt follow-up
Changes in patellar tendon complaints and shear wave velocity patterns among competitive alpine skiers during a 4-year post-growth spurt follow-up Open
Patellar tendon (PT) complaints are frequent in competitive alpine skiers and such complaints are characterized by a long-lasting affection. Since PTs are subject to maturation up to 1–2 years after growth spurt, this early career stage ma…

Patellar tendon complaints and shear wave velocity patterns in maturing alpine skiers Open
Introduction
Patellar tendinopathy is frequent in adolescent athletes and particularly accentuated in competitive alpine skiers (Fröhlich et al., 2020). Tendinopathies are characterized by long disease histories, and whether they can be h…

Three-dimensional mapping of ultrasound-derived skeletal muscle shear wave velocity Open
Introduction: The mechanical properties of skeletal muscle are indicative of its capacity to perform physical work, state of disease, or risk of injury. Ultrasound shear wave elastography conducts a quantitative analysis of a tissue’s shea…
View article: Lumbar Multifidus Morphology in Youth Competitive Alpine Skiers and Associated Sex, Age, Biological Maturation, Trunk Stability, and Back Complaints
Lumbar Multifidus Morphology in Youth Competitive Alpine Skiers and Associated Sex, Age, Biological Maturation, Trunk Stability, and Back Complaints Open
Background: The lumbar multifidus (LMF), as a dynamic stabilizer of the lumbar spine, may play an important role in the prevention of overuse-related back complaints. Hypothesis: LMF morphology is associated with trunk stability and differ…
View article: Biceps femoris long head morphology in youth competitive alpine skiers is associated with age, biological maturation and traumatic lower extremity injuries
Biceps femoris long head morphology in youth competitive alpine skiers is associated with age, biological maturation and traumatic lower extremity injuries Open
Lower extremity injuries are common in competitive alpine skiers, and the knee and lower leg are often affected. The hamstring muscles, especially the biceps femoris long head (BFlh), can stabilize the knee and the hip and may counteract v…

The Cardiovascular Response to Interval Exercise Is Modified by the Contraction Type and Training in Proportion to Metabolic Stress of Recruited Muscle Groups Open
Background: Conventional forms of endurance training based on shortening contractions improve aerobic capacity but elicit a detriment of muscle strength. We hypothesized that eccentric interval training, loading muscle during the lengtheni…

Muscle oxygen saturation in healthy subjects during interval-type exercise Open
The data reports the physiological characteristics of healthy subjects, aerobic fitness and the insertion/deletion polymorphism of the angiotensin converting enzyme gene, as well as the accrued muscle oxygen deficit and hemoglobin concentr…
