Purpose: Whole body vibration (WBV) triggers anabolic responses in various tissues, including tendons, without requiring high force production. In this waitlist-controlled equivalence trial, we tested its clinical effectiveness as an alternative treatment for patellar tendinopathy against conventional heavy slow resistance training (HSR). Methods:...

Introduction: Although a few studies suggest that young overweight to obese children and adolescents (YO) may have impaired postural control compared to young normalweight (YN) peers, little information exists about how these two groups differ in the quality of the underlying balance strategies employed. Hence, the aim of the present study was a fi...

Hamstring injuries are endemic, but influences of test-specific training and the application of different test methods on decision making remain elusive. Sport-students were randomised to isokinetic (IG) or Nordic hamstring (NG) exercise or a control group (CG) for six weeks. Training and testing procedures were matched to biomechanical parameters....
Article
Full-text available
In Super-G alpine ski racing mean speed is nearly as high as in Downhill. Hence, the energy dissipated in typical impact accidents is similar. However, unlike Downhill, on Super-G courses no training runs are performed. Accordingly, speed control through course design is a challenging but important task to ensure safety in Super-G. In four male Wor...
Article
Geographical regions possess distinct sporting cultures that can influence athletic development from a young age. The United States (US) and Austria both produce elite alpine ski racers, yet have distinct sport structures (i.e., funding, skiing prominence). In this exploratory study, we investigated sport outcomes and psychological profiles in adol...
Article

Objectives: To investigate knee, back and hip overuse injuries in top female elite alpine skiers during the off-season preparation, which has so far received little attention, and to assess their relationship with traumatic preinjuries and overall training load. Methods: A cohort of 26 females of the Swiss Alpine Ski-Team were prospectively surveye...
Article
Purpose: The aim of this study was to evaluate whether anthropometric and fitness characteristics have changed between former and current elite male and female Austrian young ski racers (U11-U15). Methods: A battery of anthropometric, general, and skiing-specific fitness tests was conducted annually. In total, 1517 participants (846 males, 671 f...

Background Despite the knee extensor weakness, less attention has been paid to the evaluation of patellar tendon after total knee arthroplasty (TKA). We previously observed patellar tendon hypertrophy after TKA. The purpose of this study was to reanalysis these ultrasound data to detect whether brightness mode ultrasound imaging reflects pathologic...

Article
Background/Aim To set a safe giant slalom course, speed needs to be controlled in certain sections. Speed may be reduced by adjusting how the gates are set on a course. We studied the effect of elements of course-setting, entrance speed and terrain incline on the mechanics of turning (ie, turn speed, turn radius, and ground reaction force and impul...

Equivocal findings exist on isokinetic and Nordic hamstring exercise testing of eccentric hamstring strength capacity. Here, we propose a critical comparison of the mechanical output of hamstring muscles as assessed with either a dynamometer (IKD) or a Nordic hamstring device (NHD). Twenty‐five volunteers (26±3 yrs) took part in a counterbalanced r...

The relative age effect (RAE) represents an asymmetry in birth quarter distribution, favoring athletes born early in the selection year and discriminating against late born athletes. The RAE was proven to be present in all age categories of national and international levels of alpine ski racing. Due to the existence of the RAE in all categories, it...

In this study, we compared a monocular computer vision (MCV)-based approach with the golden standard for collecting kinematic data on ski tracks (i.e., video-based stereophotogrammetry) and assessed its deployment readiness for answering applied research questions in the context of alpine skiing. The investigated MCV-based approach predicted the th...

Maximal oxygen uptake (V̇O2max) and muscle mass decreases with age. The loss of cardiorespiratory fitness and muscle strength is accelerated with physical inactivity and has well‐documented consequences for morbidity and all‐cause mortality. Participation in exercise training programs will improve one or more of the cardio‐metabolic risk factors, b...

Alpine ski racing is one of the most popular sports in many countries; nevertheless, selection disadvantages and severe injuries result in high dropout rates. In this review we summarize existing knowledge about the specific challenges associated with selection bias and injuries, and their effects on talent development in ski racing. The relative a...

In alpine skiing, intermediate times are usually measured with photocells. However, for practical reasons, the number of intermediate cells is limited to three–four, making a detailed timing analysis difficult. In this paper, we propose and validate a magnet-based timing system allowing for the measurement of intermediate times at each gate. Specia...

INTRODUCTION: Applying an entropy approach to assess the fluctuation patterns of gait, Buchecker et al. (2018) reported a "decomplexification" of centre of mass dynamics while participants were adapting to unstable footwear (UF), especially in the medio-lateral direction. If true, walking with UF should affect upper body function in terms of inter-...

NORWAY Patellar tendinopathy (PT) causes pain and functional limitations. Strength training regimes are successful therapeutic interventions, but often demanding and painful. Whole body vibration (WBV) training has been shown to exert an anabolic effect for bone, muscle and recently, tendon tissues. However, this intervention, which involves lower...

Arm swing has been shown to lead to greater maximal speed and movement economy in cross‐country skiing. The current study aimed to investigate how arm swing alters skiing mechanics and contributes to performance and acceleration of the athlete's centre of mass (COM). While skiing on snow seven highly skilled cross‐country skiers simulated V2‐altern...
Article
Purpose The aims of this study were to assess differences of limb symmetry index (LSI) in strength- and coordination-related tasks between high-level, competitive, noninjured ski racers of different age-related performance levels and to prospectively assess limb differences as a possible risk factor for traumatic and overuse injury in youth ski rac...

Introduction The mismatch between tendon functional demand and adaptational rate often ends in chronic pathological conditions (Riley 2004). Subsequently, affected athletes continue their daily routines in pain, although the impact of this pathology on tendon mechanics remains debated. Hence, the present study aimed to compare patellar tendon stiff...
Conference Paper
Introduction Eccentric hamstring exercises are considered to be the most effective approach to reduce the tremendous burden of posterior thigh muscle injury (Timmins et al., 2016). However, research focused on exercise-specific recruitment and/or adaptation patterns (Guex et al., 2016; Seymore et al., 2017) and neglected the sensitivity of diagnost...
Conference Paper
INTRODUCTION: High, bilateral evenly distributed eccentric knee flexion strength is critical in injury prevention (Al Attar et al., 2017) and/or athletic performance (Morin et al., 2015). However, ischiocrural muscles are, inter alia, region-specifically activated in hamstring exercises (Hegyi et al., 2017) and their strength assessment remains cha...

Accurate 3D human pose estimation from single images is possible with sophisticated deep-net architectures that have been trained on very large datasets. However, this still leaves open the problem of capturing motions for which no such database exists. Manual annotation is tedious, slow, and error-prone. In this paper, we propose to replace most o...

Background: In alpine ski racing, typical loading patterns of the back include a combined occurrence of spinal bending, torsion, and high peak loads. These factors are known to be associated with high spinal disc loading and have been suggested to be attributable to different types of spine deterioration. However, little is known about the effect...

Inertial sensor drift is usually corrected on a single-sensor unit level. When multiple sensor units are used, mutual information from different units can be exploited for drift correction. This study introduces a method for a drift-reduced estimation of three dimensional (3D) segment orientations and joint angles for motion capture of highly dynam...
