Active commuting to school among 36,781 Spanish children and adolescents: A temporal trend study.
2021
This study examines trends in the rates of active commuting to school (ACS) in Spanish children (n = 18 343; 8.93 ± 1.68) and adolescents (n = 18 438; 14.11 ± 1.58) aged 6‐18 years from 2010 to 2017. Given the study period included the economic crisis in Spain (2008‐2013), the second aim of this study was to compare ACS rates during and after the economic crisis. Data were obtained from 28 studies conducted across Spain. The overall trends in ACS were evaluated using multilevel logistic regression analysis. Among Spanish children and adolescents, the rates of ACS to school ranged around 60% between 2010 and 2017. The rates of ACS in Spanish youth did not change significantly during the 2010…
Evaluación y caracterización biomecánica de los trinquetes de pelota valenciana. (Biomechanical assessment and characterization of the Valencian ball…
2012
El trinquete es la instalacion de referencia en la practica de la pelota valenciana, donde se juegan las modalidades profesionales de escala i corda y raspall. Sin embargo, no existe una normativa ni procedimientos de ensayo especificos que permitan definir las caracteristicas mecanicas que deben reunir paredes y pavimento del trinquete, para que los jugadores tengan una practica segura y optimicen su rendimiento. El objetivo de este estudio fue analizar diferentes variables mecanicas en las instalaciones de juego, determinar los procedimientos de ensayo mas adecuados y, finalmente, proponer unos valores mecanicos que definan una instalacion de calidad. Los estudios se llevaron a cabo en 10…
The effect of a failure and submaximal blood flow restriction resistance exercise protocol on changes in muscle size, strength and swelling
2016
Masteroppgave i idrettsvitenskap - Universitetet i Agder 2016 Introduction: Blood flow restricted resistance exercise (BFRRE) can induce rapid increases in muscle size, strength and swelling. No previous research has investigated the importance of conducting BFRRE to voluntary failure and few studies has been carried out to investigate associations between swelling and muscle size. Therefore, the aim of the present study was twofold (1) compare changes in muscle size and strength between a failure (FA) and submaximal (SU) BFRRE protocol (2) investigate associations between swelling and muscle size. Methods: Seventeen untrained men had their legs randomized to FA and SU protocols. The interv…
Musculoskeletal disorders and disability among forest industry workers in lower and higher sickness absence groups: a case-control study
2019
Background: Musculoskeletal wellbeing and disorders and explanatory factors were investigated among forest industry employees. Methods: A new positive approach to maintenance of working ability focuses on being present at work. 140 individuals with low sickness absence (≤1.5% in hours during the past 6.5 years) and 140 controls with higher sickness absence (>1.5%), randomly selected from the source population (n = 636) in workplace clusters (n = 5), were studied. Questionnaire data on functioning, musculoskeletal disorders (MSD) and disability, work ability and wellbeing were collected (response rate 65%) during December 2012–January 2013. 183 employees (mean age 48.5; females 32%) particip…
Veselīga dzīvesveida pārvaldības lietotne
2022
Kvalifikācijas darbā ir izstrādāta veselīga dzīvesveida pārvaldības sistēma tīmeklī, tā kā viņa ir veidota ar React palīdzību, ir iespējams lietot konkrēto lietotni pārlūkprogrammā. Līdz šim skatoties uz lielāko daļu sporta lietotņu ir saskatāma viena kopēja īpašība tā ir vienkāršības un vienotības trūkums. Ir ļoti daudz visvisādu programmu, kuras veic funkcijas līdzīgas kā darbā izstrādātā lietotne, bet lielākā daļa no tām veic tikai vienu funkciju, proti, dod iespēju veidot treniņu kompleksus, vai skaitīt uzkrātās kalorijas, kas padara procesu grūtāku, jo ir jālēkā no lietotnes uz lietotni, ir programmas, kuras piedāvā abus variantus, bet tie ir slēgti aiz samaksas sliekšņa. Konkrētā darb…
Tūrisma biznesa loma ekonomikā un attīstības iespējas Latvijā
2018
Tūrisma nozare pēdējos gados ir piedzīvojusi nozīmīgas pārmaiņas. Mainoties ekonomiskai situācijai pasaulē, tehnoloģiju attīstībai un informācijas pieejamībai, mainās tūristu ceļošanas paradumi un prasības. Līdz ar to nemitīgi jāmainās tūrisma nozarei kā produkcijas un pakalpojumu sniedzējai. Kā viena no Latvijas prioritātēm tiek izvirzīta tūrisma potenciāla izmantošana, kuru veiksmīgi attīstot iespējams palielināt tūrisma kā nozares devumu valsts ekonomikā, uzlabojot ekonomisko situāciju valstī, tādā veidā palielinot nodarbinātību un sabiedrības dzīvi kopumā. Darba mērķis ir veikt tūrisma biznesa nozīmības novērtējumu Latvijas ekonomikā un identificēt nozares ietekmējošos faktorus, izvirzī…
Prompt Determination of the Mechanical Properties of Industrial Polypropylene Sandwich Pipes
2021
A simple and prompt method to determine the mechanical properties of industrial multilayer extrusion polypropylene pipes for a gravity sewer network is suggested. The engineering formulas included for calculating the permissible thickness and relative position of a foam core in the pipes are based on a linear-elastic approximation and the rule of mixtures. The applicability of the approximation was justified experimentally during investigation of the effective tensile characteristics of single- and multilayer pipes and each layer specimen by using traditional tests and finite-element calculations. The results obtained were used to formulate engineering recommendations for calculations of th…
Sammenhengen mellom mestringsforventning, helserelatert livskvalitet og selvrapportert fysisk aktivitet blant elever i videregående skole
2016
Masteroppgave folkehelsevitenskap - Universitetet i Agder 2016 Background: Two different intervention models were developed to increase participation in physical education in high school, targeting “motion enjoyment” and “sport enjoyment”. Both models are intended to increase the pleasure of physical activity in physical education, as well as to contribute to the development of students’ skills, abilities and increase future commitment. The intention behind the motion enjoyment model is to reinforce positive experiences which are related to physical activity, along with raising the awareness in young people of the health benefits associated with physical activity. The sport enjoyment model …
Características de la práctica físico-deportiva del alumnado con discapacidad de la Universitat de València
2015
En la actualidad, la actividad físico-deportiva es fundamental para las personas con discapacidad debido a los múltiples beneficios físicos, psicológicos y sociales que aporta (Patel y Greydanus, 2010; Slater y Meade, 2004). Estudiar las características de la práctica físico-deportiva de este colectivo puede ser útil para poder desarrollar estrategias y programas que mejoren y aumenten dicha práctica (Bragaru,van Wilgen, Geertzen, Ruijs, Dijsktra y Dekker, 2013). Pese a ello, apenas existen estudios de carácter cuantitativo sobre el tema. De acuerdo con las carencias señaladas, el objetivo de este trabajo es identificar la cuantía de la práctica físico-deportiva del alumnado con discapacida…
