Force Generation Profiles of Para-Nordic Sit-Skiers Representing Different Physical Impairments
2021
Abstract Purpose To biomechanically profile force generation connected to the complex role of the trunk in double poling in a representative sample of Para-Nordic sit-skiers. Methods Twelve male World Cup Para-Nordic sit-skiers (sport classes: LW10–12) were skiing on flat snow terrain at submaximal speed of 4.5 m/s (~ 73% maximum speed). 2D video (50 Hz) and pole force analyses (1000 Hz) were performed synchronously, examining angle, force and cycle characteristics to analyse the role of the trunk in generating propulsion. Results LW10–11.5 skiers lost between 21% and 4% propulsive force versus LW12 athletes only due to different geometrics of the trunk and pole angle at an equal axial pole…
El Mal como problema político : el “paradigma Dostoievski” y el nacimiento de la distopía
2016
Fil: Del Percio, Daniel. Pontificia Universidad Católica Argentina; Argentina Fil: Del Percio, Daniel. Universidad de Palermo. Facultad de Ciencias Sociales. Centro de Investigación en Ciencias Sociales; Argentina Fil: Del Percio, Daniel. Universidad del Salvador; Argentina Resumen: Quizás uno de los aspectos más inquietantes del mal, visto desde la metafísica, es que posee un sorprendente paralelo con el nihilismo. Sobre ambos podemos decir que son problemas que no tienen solución, pero sí historia. Desde esta perspectiva, la literatura nos ofrece una extensísima lista de ejemplos que ilustran esa doble historia, tan complementaria entre sí, al punto de que cada una permite abrir un horizo…
Copenhagen consensus statement 2019: physical activity and ageing
2019
From 19th to 22nd November 2018, 26 researchers representing nine countries and a variety of academic disciplines met in Snekkersten, Denmark, to reach evidence-based consensus about physical activity and older adults. It was recognised that the term ‘older adults’ represents a highly heterogeneous population. It encompasses those that remain highly active and healthy throughout the life-course with a high intrinsic capacity to the very old and frail with low intrinsic capacity. The consensus is drawn from a wide range of research methodologies within epidemiology, medicine, physiology, neuroscience, psychology and sociology, recognising the strength and limitations of each of the methods. …
The Copenhagen Concensus Conference 2016: Children, youth, and physical activity in schools and during leisure time
2016
From 4 to 7 April 2016, 24 researchers from 8 countries and from a variety of academic disciplines gathered in Snekkersten, Denmark, to reach evidence-based consensus about physical activity in children and youth, that is, individuals between 6 and 18 years. Physical activity is an overarching term that consists of many structured and unstructured forms within school and out-of-school-time contexts, including organised sport, physical education, outdoor recreation, motor skill development programmes, recess, and active transportation such as biking and walking. This consensus statement presents the accord on the effects of physical activity on children's and youth's fitness, health, cogniti…
Comparing Surface and Fine-Wire Electromyography Activity of Lower Leg Muscles at Different Walking Speeds.
2019
Ankle plantar flexor muscles are active in the stance phase of walking to propel the body forward. Increasing walking speed requires increased plantar flexor excitation, frequently assessed using surface electromyography (EMG). Despite its popularity, validity of surface EMG applied on shank muscles is mostly unclear. Thus, we examined the agreement between surface and intramuscular EMG at a range of walking speeds. Ten participants walked overground at slow, preferred, fast, and maximum walking speeds (1.01 ± 0.13, 1.43 ± 0.19, 1.84 ± 0.23, and 2.20 ± 0.38 m s–1, respectively) while surface and fine-wire EMG activities of flexor hallucis longus (FHL), soleus (SOL), medial gastrocnemius (MG…
Patterns and determinants of adherence to resistance and endurance training during cancer treatment in the Phys-Can RCT.
2022
Abstract Background Knowledge regarding adherence is necessary to improve the specificity of exercise interventions during cancer treatment. We aimed to determine adherence to resistance and endurance training interventions in parallel; identify subgroups with similar adherence characteristics; and examine determinants of these subgroups. Methods In the Phys-Can randomised controlled trial, participants (n = 577, 81% women, mean(SD) age 59(12) years, and 50% with BMI ≥ 25 kg/m2) starting (neo-) adjuvant treatment for breast, colorectal or prostate cancer were randomized to 6-month of high (HI) or low-to-moderate intensity (LMI) supervised, group-based resistance training and individual home…
Does inflammation markers or treatment type moderate exercise intensity effects on changes in muscle strength in cancer survivors participating in a …
2023
Abstract Background Resistance exercise has a beneficial impact on physical function for patients receiving oncological treatment. However, there is an inter-individual variation in the response to exercise and the tolerability to high-intensity exercise. Identifying potential moderating factors, such as inflammation and treatment type, for changes in muscle strength is important to improve the effectiveness of exercise programs. Therefore, we aimed to investigate if inflammation and type of oncological treatment moderate the effects of exercise intensity (high vs. low-moderate) on muscular strength changes in patients with breast (BRCA) or prostate cancer (PRCA). Methods Participants with …
Start Spreading the News: A Comparative Experiment on the Effects of Populist Communication on Political Engagement in Sixteen European Countries
2018
Although populist communication has become pervasive throughout Europe, many important questions on its political consequences remain unanswered. First, previous research has neglected the differential effects of populist communication on the Left and Right. Second, internationally comparative studies are missing. Finally, previous research mostly studied attitudinal outcomes, neglecting behavioral effects. To address these key issues, this paper draws on a unique, extensive, and comparative experiment in sixteen European countries (N = 15,412) to test the effects of populist communication on political engagement. The findings show that anti-elitist populism has the strongest mobilizing eff…
Leksinių samplaikų sąrašo tikslinimas: bandymas taikyti "Formulex" metodą
2016
Svetimkalbių vartotojų produkuojamos kalbos tekstynai pastaruoju metu neretai tiriami aprašant leksines samplaikas, t. y. pasikartojančias tam tikro ilgio žodžių sekas, jų vartojimą bei funkcijas. Tokiuose tyrimuose neišvengiamai susiduriama su iš dalies sutampančiomis ar nepilnos struktūros samplaikomis. Pavyzdžiui, keturžodės anglų kalbos samplaikos at the same time, the same time it ir but at the same yra automatiškai generuojamos kompiuterio programa kaip tekstyne pasikartojančios sekos. Tačiau ar kiekviena jų laikytina tikrąja samplaika? Ar kiekvienai iš jų galima priskirti vienokią ar kitokią funkciją? Šiame straipsnyje siekiama parodyti, kaip „Formulex” metodas (Forsyth, 2015a, 2015b…
The psychophysiological influence of exertion and affect on sport-specific cognitive and physical performance
2022
Objectives: The purpose of the present study was to examine differences in cognitive and physical performance, affective states, perceived exertion, and physiological responses between trials with cognitive, physical, or combined cognitive and physical load. Design: Randomised cross-over trial. Methods: Highly trained competitive orienteers (n = 15 men; n = 10 women) completed three randomised trials comprised of: (1) sport-specific cognitive tests; (2) 35-minute cycling time trial; and (3) combined sport-specific cognitive tests and 35-minute cycling time trial. Measures taken during the trials recorded affective states, perceived exertion, heart rate, blood lactate, cycling watts, as well…
