A gluteus-specific muscle synergy recruited during the first recovery step following a backward pitch perturbation.

The central nervous system momentarily activates a set of specific muscle synergies to maintain balance when external mechanical perturbations induce walking instability, which is critically involved in preventing falls. The activation patterns and composition of the muscle synergies recruited in the perturbed leg have not been fully characterized, and even less so for the recovery step. Here, we addressed this research gap by measuring the surface electromyographic data of the relevant muscles during a backward-pitched perturbed walk, and then extracting muscle synergy-related parameters using a non-negative matrix factorization algorithm.

Parental education and neighbourhood socioeconomic status in the prediction of childhood overweight: A multilevel analysis.

Objective: This study examined cross-level interaction between parental education and neighbourhood SES in predicting overweight including obesity among school-aged children.

Methods: This analysis used data from 19 984 children aged 5-6 years participating in the school-entry examination of the years 2015 to 2019 in the Aachen city region in Germany. We employed multilevel logistic regression models to predict overweight based on parental education and neighbourhood SES, along with their cross-level interaction, while controlling for several characteristics of the child.

Association Between Cancer-Related Fatigue and Falls in Patients With Myeloproliferative Neoplasms: Results of a Multicenter Cross-Sectional Survey From the East German Study Group for Hematology and Oncology (OSHO #97).

Objective: This study retrospectively examined the association between cancer-related fatigue (CrF) and the number of falls during the last 12 months in patients with myeloproliferative neoplasms (MPNs).

Methods: A multicenter, 1-time anonymous survey was conducted using analog and digital questionnaires. Sex-stratified multinomial logistic regression analysis was applied to investigate the association between CrF and number of falls.

Fatigue and Human Performance: An Updated Framework.

Fatigue has been defined differently in the literature depending on the field of research. The inconsistent use of the term fatigue complicated scientific communication, thereby limiting progress towards a more in-depth understanding of the phenomenon. Therefore, Enoka and Duchateau (Med Sci Sports Exerc 48:2228-38, 2016, [3]) proposed a fatigue framework that distinguishes between trait fatigue (i.

Ectomycorrhizal and non-mycorrhizal rhizosphere fungi increase root-derived C input to soil and modify enzyme activities: A C pulse labelling of Picea abies seedlings.

Consequences of interactions between ectomycorrhizal fungi (EcMF) and non-mycorrhizal rhizosphere fungi (NMRF) for plant carbon (C) allocation belowground and nutrient cycling in soil remain unknown. To address this topic, we performed a mesocosm study with Norway spruce seedlings [Picea abies (L.) H.
