In virtual reality, visual speed is usually underestimated relative to locomotor speed. Here we investigated how physical activity and fitness affect perceived visual speed when running in a treadmill-mediated virtual environment. Thirty healthy participants (ten sedentary individuals, ten team sport players and ten expert runners) ran on a treadmill at two different speeds (8, 12km/h) in...

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...

Task-dependent activation of distinct fast and slow(er) motor pathways during motor imagery

Keller, Martin ; Taube, Wolfgang ; Lauber, Benedikt

In: Brain Stimulation, 2018, p. -

Background: Motor imagery and actual movements share overlapping activation of brain areas but little is known about task-specific activation of distinct motor pathways during mental simulation of movements. For real contractions, it was demonstrated that the slow(er) motor pathways are activated differently in ballistic compared to tonic contractions but it is unknown if this also holds true...

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...
