Accuracy of PARTwear inertial sensor and Optojump optical measurement system for measuring ground contact time during running

Rahel, Ammann ; Taube, Wolfgang ; Wyss, Thomas

In: Journal of Strength and Conditioning Research, 2016, p. -

The aim of this study was to validate the detection of ground contact time (GCT) during running in two differently working systems: a small inertial measurement sensor, PARTwear (PW), worn on the shoe laces, and the optical measurement system, Optojump (OJ), placed on the track. Twelve well-trained subjects performed 12 runs each on an indoor track at speeds ranging from 3.0 - 9.0 m[middle...

The effect of whole body vibration on the H-reflex, the stretch reflex, and the short-latency response during hopping

Ritzmann, R. ; Kramer, A. ; Gollhofer, Albert ; Taube, Wolfgang

In: Scandinavian Journal of Medicine & Science in Sports, 2011, p. -

The effect of whole body vibration (WBV) on reflex responses is controversially discussed in the literature. In this study, three different modalities of reflex activation with increased motor complexity have been selected to clarify the effects of acute WBV on reflex activation: (1) the electrically evoked H-reflex, (2) the mechanically elicited stretch reflex, and (3) the short-latency...

Lower between-limb asymmetry during running on treadmill compared to overground in subjects with laterally pronounced knee osteoarthritis

Robadey, Jacques ; Staudenmann, Didier ; Schween, Raphael ; Gehring, Dominic ; Gollhofer, Albert ; Taube, Wolfgang

In: PLOS ONE, 2018, vol. 13, no. 10, p. e0205191

Subjects with knee osteoarthritis (KOA) show gait asymmetries evidenced by lower knee flexion and shorter contact times for the affected leg. Interestingly, running on a treadmill compared to running overground is also associated with lower knee flexion and shorter contact times. Thus, it is of particular interest how gait patterns are influenced by the type of ground in subjects with KOA....

Validity of sports watches when estimating energy expenditure during running

Roos, Lilian ; Taube, Wolfgang ; Beeler, Nadja ; Wyss, Thomas

In: BMC Sports Science, Medicine and Rehabilitation, 2017, vol. 9, p. 22

The aim of this study was to assess the accuracy of three different sport watches in estimating energy expenditure during aerobic and anaerobic running.

Musculoskeletal injuries and training patterns in junior elite orienteering athletes

Roos, Lilian ; Taube, Wolfgang ; Zuest, Peter ; Clénin, German ; Wyss, Thomas

In: BioMed Research International, 2015, vol. 2015, p. e259531

Findings about the relation between musculoskeletal injuries and training patterns in orienteering athletes are sparse. Therefore, the musculoskeletal injuries and training patterns of 31 Swiss elite orienteering athletes aged 18-19 years were analyzed in a retrospective study. Individual training diaries and medical records were used to assess training data and injury history, respectively....

Balance training reduces brain activity during motor simulation of a challenging balance task in older adults: an fMRI study

Ruffieux, Jan ; Mouthon, Audrey ; Keller, Martin ; Mouthon, Michaël ; Annoni, Jean-Marie ; Taube, Wolfgang

In: Frontiers in Behavioral Neuroscience, 2018, vol. 12, p. -

Aging is associated with a shift from an automatic to a more cortical postural control strategy, which goes along with deteriorations in postural stability. Although balance training has been shown to effectively counteract these behavioral deteriorations, little is known about the effect of balance training on brain activity during postural tasks in older adults. We, therefore, assessed...

Behavioral and neural adaptations in response to five weeks of balance training in older adults: a randomized controlled trial

Ruffieux, Jan ; Mouthon, Audrey ; Keller, Martin ; Wälchli, Michael ; Taube, Wolfgang

In: Journal of Negative Results in BioMedicine, 2017, vol. 16, p. 11

Background: While the positive effect of balance training on age-related impairments in postural stability is well-documented, the neural correlates of such training adaptations in older adults remain poorly understood. This study therefore aimed to shed more light on neural adaptations in response to balance training in older adults.Methods: Postural stability as well as spinal reflex and...

The faster, the better? Relationships between run-up speed, the degree of difficulty (D-score), height and length of flight on vault in artistic gymnastics

Schärer, Christoph ; Lehmann, Thomas ; Naundorf, Falk ; Taube, Wolfgang ; Hübner, Klaus

In: PLOS ONE, 2019, vol. 14, no. 3, p. e0213310

On vault in artistic gymnastics, a high run-up speed is thought to be important when performing difficult vaults. To test this assumption in a large cohort of elite athletes, we calculated the correlations between the run-up speed, scores, height and length of flight for handspring-, Tsukahara- and Yurchenko-style vaults and compared the performances of male and female elite and junior...

Changes in balance coordination and transfer to an unlearned balance task after slackline training: a self-organizing map analysis

Serrien, Ben ; Hohenauer, Erich ; Clijsen, Ron ; Taube, Wolfgang ; Baeyens, Jean-Pierre ; Küng, Ursula

In: Experimental Brain Research, 2017, vol. 235, no. 11, p. 3427–3436

How humans maintain balance and change postural control due to age, injury, immobility or training is one of the basic questions in motor control. One of the problems in understanding postural control is the large set of degrees of freedom in the human motor system. Therefore, a self-organizing map (SOM), a type of artificial neural network, was used in the present study to extract and...

The challenge of evaluating the intensity of short actions in soccer: a new methodological approach using percentage acceleration

Sonderegger, Karin ; Tschopp, Markus ; Taube, Wolfgang

In: PLOS ONE, 2016, vol. 11, no. 11, p. e0166534

There are several approaches to quantifying physical load in team sports using positional data. Distances in different speed zones are most commonly used. Recent studies have used acceleration data in addition in order to take short intense actions into account. However, the fact that acceleration decreases with increasing initial running speed is ignored and therefore introduces a bias. The...
