Age, training, and previous experience predict race performance in long-distance inline skaters, not anthropometry
2012
Knechtle, Beat | Knechtle, Patrizia | Ruest, Christoph Alexander | Rosemann, Thomas | Lepers, Romuald; International audience; ''The association of characteristics of anthropometry, training, and previous experience with race time in 84 recreational, long-distance, inline skaters at the longest inline marathon in Europe (111 km), the Inline One-eleven in Switzerland, was investigated to identify predictor variables for performance. Age, duration per training unit, and personal best time were the only three variables related to race time in a multiple regression, while none of the 16 anthropometric variables were related. Anthropometric characteristics seem to be of no importance for a fast …
Developmental changes in the microgenesis of face perception revealed by effects of context and inversion
2011
AbstractPresent studies on the development of face perception mechanisms are ambiguous about the question of whether holistic face vision arises early, or in the second decade of life (Crookes & McKone, 2009). Measuring the time course of face matching we assess effects of context and inversion as correlates of holistic processing in the microgenesis of face perception within the first 650ms, and compare among 8- to 10-year-old children and adults. Results for adults indicate dominance of holistic viewing at brief timings, which is gradually replaced by feature selective strategies enabling them to selectively attend either internal or external features, as demanded by instruction. For chil…
The importance of the reproducibility of oropharyngeal swallowing in amyotrophic lateral sclerosis. An electrophysiological study
2017
Abstract Objective To investigate electrophysiologically the reproducibility of oropharyngeal swallowing in patients with ALS. Methods We enrolled 26 ALS patients, both with and without clinical signs of dysphagia, and 30 age-matched controls. The reproducibility of the electrophysiological signals related to the oral phase (electromyographic activity of the submental/suprahyoid muscles) and the pharyngeal phase (laryngeal-pharyngeal mechanogram) of swallowing across repeated swallows was assessed. To do this we computed two similarity indexes (SI) by using previously described mathematical algorithms. Results The reproducibility of oropharyngeal swallowing was significantly reduced both in…
TMS-evoked long-lasting artefacts: A new adaptive algorithm for EEG signal correction
2017
Abstract Objective During EEG the discharge of TMS generates a long-lasting decay artefact (DA) that makes the analysis of TMS-evoked potentials (TEPs) difficult. Our aim was twofold: (1) to describe how the DA affects the recorded EEG and (2) to develop a new adaptive detrend algorithm (ADA) able to correct the DA. Methods We performed two experiments testing 50 healthy volunteers. In experiment 1, we tested the efficacy of ADA by comparing it with two commonly-used independent component analysis (ICA) algorithms. In experiment 2, we further investigated the efficiency of ADA and the impact of the DA evoked from TMS over frontal, motor and parietal areas. Results Our results demonstrated t…
Vascular risk factors in glaucoma: The results of a national survey
2007
Background The role of vascular risk factors in glaucoma is still being debated. To assess the importance of vascular risk factors in patients with primary open-angle glaucoma (POAG), data from the medical history of 2,879 POAG patients and 973 age-matched controls were collected and analyzed. Methods Design: observational survey. Setting: 35 Italian academic centers. Study population: POAG patients and age-matched controls. In order to reduce bias consecutive patients were included. Observation procedures: data concerning vascular risk factors were collected for all patients with a detailed questionnaire. A complete ophthalmological examination with assessment of intraocular pressure (IOP)…
Improving Children's Coordinative Skills and Executive Functions
2016
Recent studies have focused on the positive influence of regular physical activity on executive functioning in children. Coordinative skills (agility) and executive functions (updating, attention, inhibition and planning processes) were investigated in children before and after 6 months of a Football Exercise Program compared to a control group of sedentary peers. The participants were 44 children aged 8.8 years: Group 1 comprised 24 children in a football (i.e., soccer) exercise program and Group 2 comprised 20 sedentary children. At pre-test and post-test, coordinative skills and executive functions were measured. After the Football Exercise Program, there were significant differences be…
