Comparison of inter-trial recovery times for the determination of critical power and W' in cycling
2017
Critical Power (CP) and W’ are often determined using multi-day testing protocols. To investigate this cumbersome testing method, the purpose of this study was to compare the differences between the conventional use of a 24-h inter-trial recovery time with those of 3 h and 30 min for the determination of CP and W’. Methods: 9 moderately trained cyclists performed an incremental test to exhaustion to establish the power output associated with the maximum oxygen uptake (p V O2max), and 3 protocols requiring time-to-exhaustion trials at a constant work-rate performed at 80%, 100% and 105% of p VO2max. Design: Protocol A utilised 24-h inter-trial recovery (CP24/W’24), protocol B utilised 3-h in…
A New Reliable Performance Analysis Template for Quantifying Action Variables in Elite Men’s Wheelchair Basketball
2019
This study aimed to develop a valid and reliable performance analysis template for quantifying team action variables in elite men’s wheelchair basketball. First action variables and operational definitions were identified by the authors and verified by an expert panel of wheelchair basketball coaching staff in order to establish expert validity. A total of 109 action variable were then placed into 17 agreed Categorical Predictor Variable categories. The action variables were then used to develop a computerized performance analysis template for post-event analysis. Each possession (n = 200) from an international men’s wheelchair basketball game was analyzed by the first author on two occasio…
Methodological Guidelines Designed to Improve the Quality of Research on Cross-Country Skiing
2021
AbstractCross-country (XC) ski races involve a variety of formats, two different techniques and tracks with highly variable topography and environmental conditions. In addition, XC skiing is a major component of both Nordic combined and biathlon competitions. Research in this area, both in the laboratory and field, encounters certain difficulties that may reduce the reliability and validity of the data obtained, as well as complicate comparisons between studies. Here, 13 international experts propose specific guidelines designed to enhance the quality of research and publications on XC skiing, as well as on the biathlon and Nordic combined skiing. We consider biomechanical (kinematic, kinet…
Validation of the swimming competence questionnaire for children
2020
Two studies were employed to test the reliability and validity of the Swimming Competence Questionnaire (SCQ) among primary school children. Study 1 was a cross-sectional survey in 4959 primary school children. Study 2 was a pre-post-test quasi-experiment among 1609 primary school children who underwent a 20-lesson learn-to-swim programme. In Study 1, exploratory structural equation modelling revealed excellent goodness-of-fit and scale reliability for a two-factor model comprising distance and skill factors, which supported the construct and convergent validity. SCQ scores were significantly and positively correlated with swimming outcomes (i.e., self-efficacy, intention, swimming frequenc…
Escala de Percepción de Promoción del Bienestar para Entrenadores (EPPBE): Análisis inicial de sus propiedades psicométricas y validez. (Perception o…
2011
Este estudio analizo las propiedades psicometricas de la Escala de Percepcion de Promocion del Bienestar para Entrenadores (EPPBE), compuesta por 6 dimensiones: Autocontrol, castigo, apoyo social, apoyo a la autonomia, apoyo a la competencia y apoyo a la afiliacion. Se administro la escala a 506 entrenadores y se realizo un analisis factorial confirmatorio. La validez nomologica se analizo a traves de las relaciones de las variables con la satisfaccion de necesidades basicas y la motivacion autodeterminada. El modelo mostro un ajuste adecuado a los datos. El castigo percibido no correlaciono con el resto de variables de la escala, que si mostraron correlaciones positivas entre ellas, hasta …

Latvijas valsts sporta pārvaldības izvērtējums Eiropas Savienības sporta dimensijas ietvaros
2019
Šajā maģistra darbā “Latvijas valsts sporta pārvaldības izvērtējums Eiropas Savienības sporta dimensijas ietvaros” tika pētīta un analizēta pētīta un analizēta Latvijas valsts sporta pārvaldības pašreizējā situācija Eiropas Savienības sporta dimensijas ietvaros, tās problemātika, potenciālie riski un pilnveidošanas iespējas , kas sevī ietver gan tiesiskos, gan organizatoriskās struktūras un pārvaldības, gan finansiālos aspektus. Šī darba mērķis ir novērtēt Latvijas valsts sporta pārvaldības sistēmu un identificēt tās labas pārvaldības sistēmas pilnveidošanas iespējas, pamatojoties uz teorētisko atziņu analīzes un praktiskās situācijas izpētes rezultātiem. Darba ietvaros tika izvirzīts šāds …
Análisis 3D de la aceleración en crol en el dominio temporal y frecuencial
2012
El Estudio hace un repaso a las metodologías usadas por diferentes autores en lo que respecta al análisis, tanto frecuencia como temporal del nado a crol. El estilo libre (nado en crol) en natación, al igual que el resto de estilos (braza, espalda, mariposa) poseen una determinada coordinación para realizarse correctamente según la reglamentación vigente (FINA, 2011). En este trabajo se pretende indagar en los movimientos que se realizan en el estilo crol, principalmente las aceleraciones y desaceleraciones que se producen durante la fase de nado en el cuerpo del nadador que afectan al rendimiento. Se podría definir el término Aceleración como "toda variación de velocidad con respecto al ti…
Vaļņu trases iekļaušana skolu infrastruktūrā, to pieejamība un ietekme uz sporta stundām
2022
Darba autors diplomdarba tēmu balsta uz problēmas būtību, kas sevī ietver skolas infrastruktūras neizmantošanu vai tās neesamību, tādā veidā radot priekšstatu par ekstrēmā sporta pieejamību un ietekmi uz sporta stundām. Diplomdarba mērķis ir, pēc Skola 2030 vadlīnijām attiecībā uz sporta stundu norisi, balstoties uz teorijas materiālu, kā arī veiktās aptaujas datu analīzi, definēt sekmīgu ekstrēmā sporta integrācijas modeļa izveidi skolas sporta stundām. Diplomdarba teorētiskajā daļā tiek hronoloģiski analizēta ekstrēmā sporta teorija. Tiek uzskaitīti sasniegumi Latvijas un pasaules mērogā, kā arī atspoguļota laika gaitā esošā skolas vecuma bērnu interese par ekstrēmo sportu. Tiek aprakstīt…
