Freely chosen cadence during cycling attenuates intracortical inhibition and increases intracortical facilitation compared to a similar fixed cadence

K.Sidhu, Simranjit ; Lauber, Benedikt

In: Neuroscience, 2020, vol. 441, p. 93–101

In contrast to other rhythmic tasks such as running, the preferred movement rate in cycling does not minimize energy consumption. It is possible that neurophysiological mechanisms contribute to the choice of cadence, however this phenomenon is not well understood. Eleven participants cycled at a fixed workload of 125 W and different cadences including a freely chosen cadence (FCC, ∼72),...

Fat oxidation kinetics is related to muscle deoxygenation kinetics during exercise

Zurbuchen, Anouck ; Lanzi, Stefano ; Voirol, Ludovic ; Trindade, Cybele Barboza ; Gojanovic, Boris ; Kayser, Bengt ; Bourdillon, Nicolas ; Chenevière, Xavier ; Malatesta, Davide

The present study aimed to determine whether whole-body fat oxidation and muscle deoxygenation kinetics parameters during exercise were related in individuals with different aerobic fitness levels.Methods: Eleven cyclists [peak oxygen uptake (V.O2peak): 64.9 ± 3.9 mL⋅kg–1⋅min–1] and 11 active individuals (V.O2peak: 49.1 ± 7.4 mL⋅kg–1⋅min–1) performed a maximal incremental...

Knowledge of results during vertical jump testing: an effective method to increase the performance but not the consistency of vertical jumps

García-Ramos, Amador ; Janicijevic, Danica ; Cobo-Font, Juande ; Marcos-Frutos, Daniel ; Fernandes, John F. T. ; Taube, Wolfgang ; Pérez-Castilla, Alejandro

In: Sports Biomechanics, 2020, vol. 0, no. 0, p. 1–13

This study aimed to determine whether the provision of jump height feedback (knowledge of result; KR) can increase the performance and the consistency of output variables. In a randomised order, sixteen participants performed six squat or countermovement jumps (three from a 90º knee angle and three from a self-preferred knee angle) with or without KR over four sessions. The provision of KR...

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...
