Training‐, muscle‐ and task‐specific up‐ and downregulation of cortical inhibitory processes

Taube, Wolfgang ; Gollhofer, Albert ; Lauber, Benedikt

In: European Journal of Neuroscience, 2020, vol. 51, no. 6, p. 1428–1440

Motor cortical contribution was shown to be important for balance control and for ballistic types of movements. However, little is known about the role of cortical inhibitory mechanisms and even less about long(er)‐term adaptations of these inhibitory processes. Therefore, the aim of the present study was to investigate the role of intracortical inhibition before and after four weeks of ...

Countermovement jump training is more effective than drop jump training in enhancing jump height in non-professional female volleyball players

Ruffieux, Jan ; Wälchli, Michael ; Kim, Kyung-Min ; Taube, Wolfgang

In: Frontiers in Physiology, 2020, vol. 11, p. -

The aim of the present study was to compare the effects of countermovement jump (CMJ) and drop jump (DJ) training on the volleyball-specific jumping ability of non-professional female volleyball players. For that purpose, 26 female volleyball players (15–32 years) were assigned to either a CMJ (20.4 ± 3.1 years, 171.0 ± 3.0 cm) or a DJ training group (22.0 ± 4.4 years, 168.2 ± 5.0 cm), ...

Augmented-feedback training improves cognitive motor performance of soccer players

Hicheur, Halim ; Chauvin, Alan ; Cavin, Vincent ; Fuchslocher, Joerg ; Tschopp, Markus ; Taube, Wolfgang

In: Medicine & Science in Sports & Exercise, 2020, vol. 52, no. 1, p. 141–152

Purpose In this study, we tested the hypothesis that augmented feedback (AF) training can improve both perceptual–cognitive and/or motor skills specific to soccer.Methods Three groups of young elite players (U14–U15 categories) performed a test consisting in passing the ball as accurately and as quickly as possible toward a visual target moving briefly across a large screen located at 6 m...

Specific eccentric–isokinetic cluster training improves static strength elements on rings for elite gymnasts

Schärer, Christoph ; Tacchelli, Lisa ; Göpfert, Beat ; Gross, Micah ; Lüthy, Fabian ; Taube, Wolfgang ; Hübner, Klaus

In: International Journal of Environmental Research and Public Health, 2019, vol. 16, no. 22, p. 4571

In gymnastics, coaches are constantly searching for efficient training methods in order to improve the athletes’ performance. Therefore, in this study we aimed to investigate the effects of a novel, four-week, gymnastic-specific, eccentric–isokinetic (0.1 m/s) cluster training on a computer-controlled training device on the improvement of two static strength elements on rings (swallow and...

Simple assessment of height and length of flight in complex gymnastic skills: validity and reliability of a two-dimensional video analysis method

Schärer, Christoph ; Siebenthal, Luca von ; Lomax, Ishbel ; Gross, Micah ; Taube, Wolfgang ; Hübner, Klaus

In: Applied Sciences, 2019, vol. 9, no. 19, p. 3975

In artistic gymnastics, the possibility of using 2D video analysis to measure the peak height (hpeak) and length of flight (L) during routine training in order to monitor the execution and development of difficult elements is intriguing. However, the validity and reliability of such measurements remain unclear. Therefore, in this study, the hpeak and L of 38 vaults, performed by top-level...

Changes in spinal and corticospinal excitability in patients with chronic ankle instability: a systematic review with meta-analysis

Kim, Kyung-Min ; Kim, Joo-Sung ; Cruz-Díaz, David ; Ryu, Seungho ; Kang, Minsoo ; Taube, Wolfgang

In: Journal of Clinical Medicine, 2019, vol. 8, no. 7, p. 1037

The objective of this systematic review with meta-analysis was to determine alterations in spinal and corticospinal excitability of ankle muscles in patients with chronic ankle instability (CAI) compared to uninjured controls. Independent researchers performed comprehensive literature searches of electronic databases and included studies that compared groups with and without CAI and...

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...

Mental imagery and colour cues can prevent interference between motor tasks

Lauber, Benedikt ; Kurz, Alexander ; Gollhofer, Albert ; Taube, Wolfgang

In: Neuropsychologia, 2019, vol. 124, p. 202–207

Motor interference can be observed when two motor tasks are learnt in subsequent order. The aim of the current study was to test two approaches potentially mitigating interference effects. The first approach used contextual colour cues requiring only little cognitive attention thus being assumed to be primarily implicit while the second, mental practice/rehearsal that demands much more active...

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...
