Tendon length estimates are influenced by tracking location
2022
Abstract Purpose Measurement of medial gastrocnemius (MG) tendon length using ultrasonography (US) requires the muscle–tendon junction (MTJ) to be located. Previously, the MG MTJ has been tracked from different proximo-distal locations near the MTJ, which could influence estimates of tendon length change due to the different characteristics of the aponeurosis and tendon. We used US to evaluate the effect of tracking point location on MG MTJ displacement during maximal and submaximal (10, 20 and 30% of the non-injured maximal) isometric plantar flexion contractions. Methods Displacement behaviour of MTJ was tracked from (1) the exact MTJ; and (2) from an insertion point of a muscle fascicle …
Inter‐individual variation of the urinary steroid profiles in Swedish and Norwegian athletes
2020
The steroidal module of the Athlete Biological Passport (ABP) aims to detect doping with endogenous steroids, e.g. testosterone (T), by longitudinally monitoring several biomarkers. These biomarkers are ratios combined of urinary concentrations of testosterone and metabolically related steroids. However, it is evident after five years of monitoring steroid passports, that there are large variations in the steroid ratios complicating its interpretation. In this study, we used over 11 000 urinary steroid profiles from Swedish and Norwegian athletes to determine both the inter‐ and intra‐individual variations of all steroids and ratios in the steroidal passport. Furthermore, we investigated if…
Restitusjonsvaner hos unge toppidrettsutøvere i Sør-Norge : En kartleggingsstudie av utholdenhet- og ballspillutøvere
2018
Masteroppgave idrettsvitenskap ME517 - Universitetet i Agder 2018 Background: In order to perform optimally in training and competition, the recovery inbetween, through adequate diet and sufficient sleep/rest, is of great importance. Up until now, most studies have only featured adult athletes. Similarly, studies conducted on young athletes, as well as across sports, are limited. Purpose: The purpose of this study was to assess the habits of recovery, in terms of diet and sleep, with regards to the recommendations given by Helsedirektoratet and Olympiatoppen. Further investigating the use of different recovery strategies, among young elite athletes in southern Norway. Method: A total of 36 …
Physiotherapists’ validating and invalidating communication before and after participating in brief cognitive functional therapy training : Test of c…
2021
Objective The aim of this study was to investigate physiotherapists’ validating and invalidating communication, before and after brief Cognitive Functional Therapy (CFT) training that included a session on validation skills. Associations between validation/invalidation and the characteristics of the interviews and physiotherapists were also explored. Methods Eighteen physiotherapists treating patients with low back pain participated in the study. The study had a within-group design in which validation and invalidation for physiotherapists were rated before and after training using a reliable observational scale. We also collected data on interview length and physiotherapists’ and patients’ …
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…
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 …

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…
Velosatiksmes vides ieguvumu novērtējums. Rīgas piemērs
2018
Transporta radītais piesārņojums ir strauji augoša problēma ne tikai Rīgā, bet arī globāli. Nomainot transporta veidu no autotransporta uz velotransportu, ir iespējami ekonomiskie ieguvumu, t.sk. vides jomā. Maģistra darbā analizēti velosatiksmes potenciālie ekonomiskie un vides ieguvumi Rīgā, kuri saskaņā ar Eiropas Riteņbraucēju Federācijas (ERF) aprēķiniem Eiropā var sasniegt pat 513 miljardus EUR. Analīze veikta izmantojot ERF speciālizētu metodiku, situācijas raksturojumlielumi iegūti intervijās, aptaujās un apkopojot statistiskos rādītājus. Papildus, lai novērtētu autotransporta radītā piesārņojuma ietekmes samazināšanos, modelēta piesārņojuma izkliede ielas kanjonā (Kr. Valdemāra iel…
