Predictors of In‐School and Out‐of‐School Sport Injury Prevention : A Test of The Trans‐Contextual Model
2021
The current study aimed to predict secondary school students' motivation toward sport injury prevention in 'in-school' and 'out-of-school' contexts, and their sport injury prevention behaviour at 3-month follow-up using the trans-contextual model (TCM). Hong Kong secondary school students (N = 1,566; mean age = 13.34 years, range = 11 to 19; female = 49.42%) were recruited. Participants were asked to complete a survey comprising previously-validated scales measuring TCM constructs at baseline, and a measure of sport injury prevention behaviour at follow-up three months later. Structural equation modeling (SEM) was used to examine the hypothesised paths among TCM constructs. A SEM specifying…
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 …
The effects on riding performance using active vs passive recovery during a simulated motocross race
2017
Aleix Ollé Casanovas. 2017. The effects on riding performance using active vs passive recovery during a simulated motocross race. University of Jyväskylä. 53p. The aim of the present study was to examine the effect of active and passive recovery methods in order to improve physical performance between motocross races. Exercise induced muscle damage post motocross racing was assessed as well. Participants performed 2 races of 30 minutes with one hour break in between. During the break they performed either active or passive recovery protocols. Specific motocross performance outcomes and athlete’s physical conditions were measured during, and before and after every motocross race. Lap times (…

Psychological processes of ACL-patients' post-surgery rehabilitation : A prospective test of an integrated theoretical model
2020
Objectives: The aim of this prospective study was to examine the utility of an integrated model comprising constructs from self-determination theory (SDT) and the theory of planned behavior (TPB) in predicting adherence to a post-surgery rehabilitation program in patients receiving anterior cruciate ligament (ACL) reconstruction. Constructs of the integrated model measured at baseline were expected to predict patients' rehabilitation adherence two months later. Method: Patients (N = 121, M age = 27.62, range = 18–53; 36.66% female) scheduled to have ACL reconstruction surgery within two months were recruited from a Hong Kong public hospital. At baseline and two-month follow-up, patients com…
Psychosocial impact of career-ending injuries in professional ice hockey players : a qualitative study
2014
Injuries are a regular occurrence amongst athletes, and on occasion so severe as to impact the continuation an athlete’s career. Retirement from sport, in any circumstances can be a difficult transition for an athlete, particularly when participation in sport has formed a significant part of their identity, personality, and life as a whole. Research in this area is limited, as existing studies focus on injury and career termination separately. Thus, the purpose of this study was to document the lived experiences of professional ice hockey players who have encountered career-ending sports injuries. Three former professional Finnish ice hockey players participated in this study, all of who ha…
Näkövammaisten apuvälineiden käytettävyys
2015
Näkövammaisille apuvälineet ovat elämää helpottavia, hyödyllisiä, pakollisia, kiusallisiakin mutta välttämättömiä. Ne tarjoavat mahdollisuuden itsenäiseen elämään, harrastamiseen ja työskentelyyn ihmisille, joille se ei ilman olisi mah-dollista. Tutkimuksessa halusin selvittää, millä tasolla näkövammaisten apuvälineiden käytettävyys on tällä hetkellä ja mitä parannettavaa siinä olisi tulevaisuudessa. Tarkoitus oli myös selvittää, mitä apuvälineitä näkövammaiset oikeasti käyttävät. Erityishuomiota tutkimuksessa saivat liikkumisen apuvälineet. Selvittääkseni näitä asioita suoritin käyttäjäkyselyn varsinaiselle käyttäjäryh-mälle. Tämä tehtiin näkövammaisten keskustelufoorumin kautta sähköisest…

Akillesjänteen paksuuden, neovaskularisaation esiintymisen ja isometrisen voimantuoton muutokset 12 viikon eksentrisen harjoittelun aikana akillesjän…
2015
Pohkeen lihakset ovat tärkeässä roolissa jokapäiväisessä liikkumisessamme. Erilaisten liikuntasuoritusten aikana tuotetut voimat pohkeen ja säären lihaksissa välittyvät akillesjänteeseen ja voivat osaltaan olla aiheuttamassa urheilussa usein yleisiä akillesjänteen kuormitusvammoja, kuten akillesjänteen tulehduksia tai repeämiä. Tutkimuksen tavoitteena oli selvittää akillesjännevaivoista kärsivien akillesjänteen anatomiaa sekä voimantuoton muutoksia kolmen kuukauden eksentrisen kuntoutusjakson aikana. Anatomian osalta tarkastelun kohteena olivat akillesjänteen paksuuden ja uudisverisuonituksen (neovaskularisaation) esiintymisen muutokset. Akillesjännevaivoista kärsivien ja terveiden vapaaeht…
