Force Generation Profiles of Para-Nordic Sit-Skiers Representing Different Physical Impairments
2021
Abstract Purpose To biomechanically profile force generation connected to the complex role of the trunk in double poling in a representative sample of Para-Nordic sit-skiers. Methods Twelve male World Cup Para-Nordic sit-skiers (sport classes: LW10–12) were skiing on flat snow terrain at submaximal speed of 4.5 m/s (~ 73% maximum speed). 2D video (50 Hz) and pole force analyses (1000 Hz) were performed synchronously, examining angle, force and cycle characteristics to analyse the role of the trunk in generating propulsion. Results LW10–11.5 skiers lost between 21% and 4% propulsive force versus LW12 athletes only due to different geometrics of the trunk and pole angle at an equal axial pole…
Evaluating objective measures of impairment to trunk strength and control for cross-country sit skiing
2021
AbstractIn Paralympic cross-country sit skiing, athlete classification is performed by an expert panel, so it may be affected by subjectivity. An evidence-based classification is required, in which objective measures of impairment must be identified. The purposes of this study were: (i) to evaluate the reliability of 5 trunk strength measures and 18 trunk control measures developed for the purposes of classification; (ii) to rank the objective measures, according to the largest effects on performance. Using a new testing device, 14 elite sit-skiers performed two upright seated press tests and one simulated poling test to evaluate trunk strength. They were also subjected to unpredictable bal…
Inkluusion nosteet ja esteet liikuntakulttuurissa : tavoitteena kaikille avoin liikunnallinen iltapäivätoiminta

Elinsiirtoliikunnan viikon vapaaehtoisten profiili, motiivit ja aikeet vapaaehtoistyöhön jatkossa
2017
Tutkimuksen tarkoituksena oli kuvailla European Transplant Sport Week (ETSW) -tapahtuman toteuttamista tukevissa vapaaehtoistehtävissä toimineiden vapaaehtoisten profiilia sekä selvittää vapaaehtoisten osallistumisen motiiveja. Lisäksi tutkittiin vapaaehtoisten tietämystä elinsiirron saaneiden liikunnasta ja aikomuksia toimia vapaaehtoisena jatkossa. Tutkimuksessa käsiteltiin vapaaehtoisuutta jälkimodernin yhteiskunnan piirteiden näkökulmasta, jossa refleksiivinen yksilöllisiä tarkoitusperiä tavoitteleva ja episodimaisuuteen perustuva vapaaehtoisuus on syrjäyttämässä aiempaa perinteisiin ja yhteisöllisyyteen tukeutunutta kollektiivista vapaaehtoisuutta. Tutkimus oli kvantitatiivinen tapaust…
Simulated skiing as a measurement tool for performance in cross-country sit-skiing
2019
The International Paralympic Committee mandates the development of an evidence-based classification system, which requires a measure of performance. Performance in cross-country sit-skiing is mainly dependent on force generated during the poling phase and is enhanced by trunk flexion–extension movements. Since all sit-skiers have neuromuscular impairment, but different ability to control the trunk, this study aimed to verify if simulated action of poling on an adapted ergometer, together with a cluster analysis, could be used for grouping participants with different impairments according to their performance. On the ergometer, eight male and five female participants performed seven poling c…
Social Learning among Transplant Event Volunteers
2019
Volunteering in adapted sports competitions has not been studied as much as in other competitions. Survey data from volunteers in a supportive role at the European Transplant Sport Week 2016 in Finland were analysed to report the way involvement in the event increased knowledge of transplantation. Through social learning theory, the aim of the study was to report the associations between changes in knowledge, training and volunteering experience of supportive role volunteers. A representative sample of the adult volunteers (n=95, Male=35, Female=60; Disabled=31, non-Disabled=64; Mage=49.7y old, SD=16.8) responded to a web-based survey. Questions included self-perceived knowledge of transpla…
Different sitting positions influence cross country sit skiers performance : Sitting position influence on force generation and cycle characteristics
2018
Cross country sit skiing is a Paralympic discipline in which athletes due to physical impairment ski sitting on a sit-ski. The impairment influences performance directly and also through sitting position. Athletes with a better trunk control usually adopt a sitting position called “kneeing” in which the hip joints are higher than the knee joints. In contrast, athletes with high impact of impairment prefer a sitting position called “knee high” in which the hip joints are lower than the knee joints. Able bodied athletes skiing on the ergometer in these two sitting positions showed different performance. However, to the best of authors’ knowledge, no studies have examined performance, force pr…
Effect of Sitting Posture on Sit-Skiing Economy in Non-disabled Athletes
2020
This study focused on resolving the differences in economy between two common sit-skiing postures used by disabled athletes, suspected to be the most and least effective. Ten experienced non-disabled male cross-country skiers went through an incremental testing protocol with an ergometer simulating double poling in two sitting postures “kneeing” and “knee-high.” The protocol consisted of 3 × 4 min steady-state stages (13, 22, and 34% of maximal sprint power output). Subjects' respiratory gases and heart rate were measured and blood lactate concentrations were determined. In addition, pulling forces and motion capture recordings were collected. Oxygen consumption was 15.5% (p < 0.01) higher …
Naisvammaisurheilu kaksinkertaisen toiseuden ja ruumisprojektin risteyksessä : arvojen ja asenteiden muutos naisvammaisurheilijan kokemana
2012
Tässä tutkielmassa tarkastellaan naisvammaisurheilijaa ja -urheilua kaksinkertaisen toiseuden ja ruumisprojektin näkökulmista. Tarkoituksena on tehdä näkymättömiä disablistisia eli vammauttavia konstruktioita eri diskursseissa näkyväksi. Käsitteiden kaksinkertainen toiseus ja ruumisprojekti määrittäminen tapahtuu kirjallisuuskatsauksen kautta. Kirjallisuuskatsaus osoittaa käsitteisiin liittyvän alakäsitteitä, jotka muodostavat monimutkaisen ja –tasoisen sosiaalisen ja kulttuurisen konstruktion. Samalla käsitteet toimivat tutkimuksen viitekehyksenä. Tutkimusmenetelmänä käytettiin teemahaastatteluja, joita analysoitiin sekä deduktiivisesti että induktiivisesti. Haastatteluun osallistui kahdek…
