Accuracy of elevation recording using sport watches while walking and running on hilly and flat terrain

Ammann, Rahel ; Taube, Wolfgang ; Kummer, Fabian ; Wyss, Thomas

In: Sports Engineering, 2016, vol. 19, no. 4, p. 283–287

Elevation gain (EG) is a significant contributor to the total workload in many endurance sports. Hence, the aim of this study was to evaluate the accuracy of elevation recording as assessed by popular sport watches. Eighteen participants walked and ran at different speeds in various weather conditions in two terrain types: on a hilly 2490 m course with a total EG of 90 m and on a flat 1200 m...

The influence of the gait-related arm swing on elevation gain measured by sport watches

Ammann, Rahel ; Taube, Wolfgang ; Neuhaus, Matthias ; Wyss, Thomas

In: Journal of Human Kinetics, 2016, vol. 50, no. 2, p. 53–60

The elevation gain is an important contributor to the total workload in endurance sports. The purpose of this study was to evaluate the influence of the arm swing on elevation gain in three sport watches (Garmin® Forerunner 910XT, Polar® RS800CX and Suunto® Ambit2) on a flat 400 m outdoor track. Altogether, a total of 120 repetitions of 1,200 m were performed at self-selected speeds...

Neck muscle vibration can improve sensorimotor function in patients with neck pain

Beinert, Konstantin ; Keller, b , Martin ; Taube, Wolfgang

In: The Spine Journal, 2015, vol. 15, no. 3, p. 514–521

Background: context People with neck pain display a diminished joint position sense and disturbed postural control, which is thought to be a result of impaired somatosensory afferent activity and/or integration. Afferent processing can be artificially manipulated by vibration and was shown to reduce motor performance in healthy subjects. However, the effect of vibration on sensorimotor function...

Neural correlates of maladaptive pain behavior in chronic neck pain - a single case control fMRI study

Beinert, Konstantin ; Mouthon, Audrey ; Keller, Martin ; Mouthon, Michael ; Annoni, Jean-Marie ; Taube, Wolfgang

In: Pain Physician, 2017, vol. 20, no. 1, p. E115–E125

Chronic neck pain patients display functional impairments like decreased range of motion, decreased strength, and reduced sensorimotor function. In patients without structural damage, the reason for the persistence of pain is not well understood. Therefore, it is assumed that in chronic pain states, memory processes play an important role. We have now detected and tested a patient that might...

The effect of balance training on cervical sensorimotor function and neck pain

Beinert, Konstantin ; Taube, Wolfgang

In: Journal of Motor Behavior, 2013, vol. 45, no. 3, p. 271–278

The authors’ aim was to evaluate the effect of balance training on cervical joint position sense in people with subclinical neck pain. Thirty-four participants were randomly assigned to balance training or to stay active. Sensorimotor function was determined before and after 5 weeks of training by assessing the ability to reproduce the neutral head position and a predefined rotated head...

Effect of different loading conditions on running mechanics at different velocities

Carretero-Navarro, Germán ; Márquez, Gonzalo ; Cherubini, Doménico ; Taube, Wolfgang

In: European Journal of Sport Science, 2019, vol. 19, no. 5, p. 595–602

Weighted vests are widely used to improve running economy and performance. However, it is not well-studied how running mechanics are adapted to counteract the higher peak vertical ground reaction forces (Fpeak) while running with such a device. Therefore, the present study aimed to investigate the effects of different loading conditions on running mechanics at different velocities. Thirteen...

Measuring physical load in soccer: strengths and limitations of 3 different methods

Fischer-Sonderegger, Karin ; Taube, Wolfgang ; Rumo, Martin ; Tschopp, Markus

In: International Journal of Sports Physiology and Performance, 2019, vol. 14, no. 5, p. 627–634

To investigate the strengths and limitations of different indicators to measure physical load. Furthermore, indicators were evaluated for discrimination between performance levels and playing positions. Methods: Ninety positional match files from 70 elite players and 91 match files from 69 subelite players were collected during 14 official under-18 matches using a local position measurement...

Gait asymmetry during 400- to 1000-m high-intensity track running in relation to injury history

Gilgen-Ammann, Rahel ; Taube, Wolfgang ; Wyss, Thomas

In: International Journal of Sports Physiology and Performance, 2016, vol. 12, no. Suppl 2, p. S2-157

Purpose: To quantify gait asymmetry in well-trained runners with and without previous injuries during interval training sessions incorporating different distances.Methods: Twelve well-trained runners participated in 8 high-intensity interval-training sessions on a synthetic track over a 4-wk period. The training consisted of 10 × 400, 8 × 600, 7 × 800, and 6 × 1000-m running. Using an...

Effects of age on the soccer-specific cognitive-motor performance of elite young soccer players: Comparison between objective measurements and coaches’ evaluation

Hicheur, Halim ; Chauvin, Alan ; Chassot, Steve ; Chenevière, Xavier ; Taube, Wolfgang

In: PLOS ONE, 2017, vol. 12, no. 9, p. e0185460

The cognitive-motor performance (CMP), defined here as the capacity to rapidly use sensory information and transfer it into efficient motor output, represents a major contributor to performance in almost all sports, including soccer. Here, we used a high-technology system (COGNIFOOT) which combines a visual environment simulator fully synchronized with a motion capture system. This system...

Improved postural control after slackline training is accompanied by reduced H-reflexes

Keller, M. ; Pfusterschmied, J. ; Buchecker, M. ; Müller, E. ; Taube, Wolfgang

In: Scandinavian Journal of Medicine & Science in Sport, 2012, vol. 22, no. 4, p. 471–477

“Slacklining” represents a modern sports activity where people have to keep balance on a tightened ribbon. The first trials on the slackline result in uncontrollable lateral swing of the supporting leg. Training decreases those oscillations and therefore improves postural control. However, the underlying neural mechanisms are not known. Therefore, the present study aimed to highlight...
