Physical activity as a protective factor for dementia and Alzheimer’s disease: systematic review, meta-analysis and quality assessment of cohort and …
2022
ObjectivePhysical activity (PA) is associated with a decreased incidence of dementia, but much of the evidence comes from short follow-ups prone to reverse causation. This meta-analysis investigates the effect of study length on the association.DesignA systematic review and meta-analysis. Pooled effect sizes, dose–response analysis and funnel plots were used to synthesise the results.Data sourcesCINAHL (last search 19 October 2021), PsycInfo, Scopus, PubMed, Web of Science (21 October 2021) and SPORTDiscus (26 October 2021).Eligibility criteriaStudies of adults with a prospective follow-up of at least 1 year, a valid cognitive measure or cohort in mid-life at baseline and an estimate of the…
¿Hay beneficios psicosociales por la práctica Pilates?: un análisis de la literatura científica
2014
En los últimos 5 años, las bases de datos analizadas muestran un notable incremento en el número de publicaciones sobre Pilates. La enorme difusión y popularidad del método Pilates podría deberse a los beneficios físicos, psíquicos y sociales que las personas podrían obtener con su práctica. Desde el ámbito científico, existe la necesidad de actualizar y evaluar objetivamente los resultados ya existentes sobre los posibles beneficios que puede producir la práctica de Pilates sobre la salud. Esta revisión, pretende comprobar si hay una suficiente fundamentación científica que justifique sus beneficios en la salud psicológica de los practicantes de Pilates. Para ello se ha realizado una búsqu…
Career Adapt-Abilities Scale – Dual Career Form (CAAS-DC): psychometric properties and initial validation in high-school student-athletes
2016
Talented adolescent athletes attempting to sustain academic and vocational training alongside the increasing demands of their athletic career often encounter difficulties, including lower vocational readiness and the challenge of adapting to life after elite sport. Therefore, it is necessary to better understand the specific competencies that youth athletes can draw upon to successfully combine sport and education into a dual career pathway. Building on the existing Career Adapt-Abilities Scale [Savickas & Porfeli, (2012). Career adapt-abilities scale: Construction, reliability, and measurement equivalence across 13 countries. Journal of Vocational Behavior, 80(3), 661–673], we developed a …
Levels and Changes of Physical Activity in Adolescents during the COVID-19 Pandemic: Contextualizing Urban vs. Rural Living Environment
2020
The COVID-19 pandemic and the social distancing implemented shortly after influence physical activity levels (PALs). The purpose of this investigation was to evaluate the changes in PAL and factors associated with PALs among Croatian adolescents while considering the impact of community (urban vs. rural living environment). The sample included 823 adolescents (mean age: 16.5 ±
Effects of training on bone metabolism in young athletes
2021
Purpose. This study investigated the effects of two types of training on the bone formation marker of osteocalcin and the bone resorption marker of tartrate-resistant acid phosphatase isoenzyme 5b (TRAP5b) in young track and field boys and girls. Methods. The 14-year-old group (10 boys, 10 girls) performed first time an intensive and supervised 8-week plyometric training. In the 17-year-old group (13 athletic boys, 6 control boys, 12 athletic girls, 6 control girls), the normal many-sided track and field training lasted 6 months. Results. Significant increases were noticed in osteocalcin (p < 0.01) both in younger boys and girls. The 20-m sprint performance improved in girls (p < 0.01) and …
Encuentro de saberes: Huellas de memoria pluriversa y descolonización de la Universidad contemporánea
2018
This paper studies the Encounter of Knowledge as a project that, by welcoming mestres and mestras of ancestral knowledge into universities, contributes to decolonize higher education, broadening its field of memory. Based on a systematization exercise, we established a theoretical dialogue with Bajtin and Bejamin. Based on the participation of four mestres -Lucely Pío, raicera del Cerrado, Mãe Lu and Tata Mutá Imé, religious leaders of Candomblé and the political leader and shaman Álvaro Tukano of the Tukano nation- we show how the project promotes in the contemporary Brazilian university a space of mnemic pluriversity, capable of activating diverse narrative planes (biographical, political…
Physical exercise increases adult hippocampal neurogenesis in male rats provided it is aerobic and sustained
2016
Aerobic exercise, such as running, has positive effects on brain structure and function, such as adult hippocampal neurogenesis (AHN) and learning. Whether high-intensity interval training (HIT), referring to alternating short bouts of very intense anaerobic exercise with recovery periods, or anaerobic resistance training (RT) has similar effects on AHN is unclear. In addition, individual genetic variation in the overall response to physical exercise is likely to play a part in the effects of exercise on AHN but is less well studied. Recently, we developed polygenic rat models that gain differentially for running capacity in response to aerobic treadmill training. Here, we subjected these l…
Intérêts et limites de l’electrostimulation pour l’évaluation, le traitement et la prévention des altérations neuromusculaires induites par l’exercic…
2004
L'objectif de ce travail était d'une part d'étudier les altérations neuromusculaires induites par un exercice excentrique sollicitant les muscles extenseurs du genou, et d'autre part d'étudier l'efficacité de l'électrostimulation (ES) comme moyen d'évaluation, de traitement et de prévention de ces altérations. La première étude de ce travail consistait à évaluer les contributions des mécanismes centraux et périphériques à la diminution de la contraction maximale volontaire observée après l'exercice excentrique. La fatigue basse fréquence (FBF) et la fatigue centrale expliquaient principalement la diminution du moment maximal volontaire après l'exercice excentrique. Le but de la deuxième étu…
Acute and chronic effects of cold treatment on physiological variables and neuromuscular function during a short training period in men
2015
Introduction. Recovery following various physical exercises is a complicated process. The exercise session can involve strong demands on both muscle structure and energy production (aerobic and anaerobic). Many exercise sessions also induce muscle damage (exercise induced muscle damage; EIMD). Different recovery methods attempt to alleviate or prevent EIMD and its associated symptoms, such as muscle soreness and swelling, and reduction in muscle function. One of the used strategies is cold treatment (cryotherapy), which decreases tissue temperature and subsequently effects on e.g. blood flow, metabolism and neural conductance velocity. To date, there is conflicting evidence to support the u…
Rethinking validity in qualitative sport and exercise psychology research: a realist perspective
2019
Over the last two decades, the relativist approach has significantly shaped debates about the quality and rigour of qualitative research in sport and exercise psychology (SEP). In the absence of any published critiques of relativism in SEP, this paper problematises its central claims with a focus on the most recent contribution offered by Smith and McGannon (2018 Smith, B., & McGannon, K. R. (2018). Developing rigor in qualitative research: Problems and opportunities within sport and exercise psychology. International Review of Sport and Exercise Psychology, 11, 101–121. doi: 10.1080/1750984X.2017.1317357[Taylor & Francis Online], [Web of Science ®], , [Google Scholar]. Developing rigor in …
