Sedentary behavior in children by wearable cameras: development of an annotation protocol

Hänggi, Johanna M. ; Spinnler, Simon ; Christodoulides, Efstathios ; Gramespacher, Elke ; Taube, Wolfgang ; Doherty, Aiden

In: American Journal of Preventive Medicine, 2020, vol. 59, no. 6, p. 880–886

Introduction: There is increasing evidence that not all types of sedentary behavior have the same harmful effects on children's health. Hence, there has been a growing interest in the use of wearable cameras. The aim of this study is to develop a protocol to categorize children's wearable camera data into sedentary behavior components.Methods: Wearable camera data were collected in 3...

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...

Effects of continuous theta burst stimulation over the left DLPFC on mother tongue and second language production in late bilinguals: a behavioral and ERP study

Jost, Lea B. ; Pestalozzi, Maria I. ; Cazzoli, Dario ; Mouthon, Michael ; Müri, René M. ; Annoni, Jean‑Marie

In: Brain Topography, 2020, vol. 33, no. 4, p. 504–518

Clinical, neuroimaging, and non-invasive brain stimulation studies have associated the dorsolateral prefrontal cortex (DLPFC) with the multilingual language control system. Here, we investigated if this role is increased during the processing of the non- dominant language due to the higher cognitive/attentional demands. We used an inhibitory repetitive transcranial magnetic stimulation (rTMS)...

Preconditioning cathodal transcranial direct current stimulation facilitates the neuroplastic effect of subsequent anodal transcranial direct current stimulation applied during cycling in young adults

Pourmajidian, Maryam ; Lauber, Benedikt ; Sidhu, Simranjit K

In: Neuroscience Letters, 2020, vol. 714, p. 134597

The study aimed to examine the effect of a pre-conditioning cathodal transcranial direct current stimulation (ctDCS) before subsequent anodal-tDCS (atDCS) was applied during low workload cycling exercise on the corticospinal responses in young healthy individuals. Eleven young subjects participated in two sessions receiving either conditioning ctDCS or sham stimulation, followed by atDCS...

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...

Alterations in the cortical control of standing posture during varying levels of postural threat and task difficulty

Tokuno, Craig D. ; Keller, Martin ; Carpenter, Mark G. ; Márquez, Gonzalo ; Taube, Wolfgang

In: Journal of Neurophysiology, 2018, vol. 120, no. 3, p. 1010–1016

Cortical excitability increases during the performance of more difficult postural tasks. However, it is possible that changes in postural threat associated with more difficult tasks may in themselves lead to alterations in the neural strategies underlying postural control. Therefore, the purpose of this study was to examine whether changes in postural threat are responsible for the...
