Balance Perturbations as a Measurement Tool for Trunk Impairment in Cross-Country Sit Skiing
2018
In cross-country sit-skiing, the trunk plays a crucial role in propulsion generation and balance maintenance. Trunk stability is evaluated by automatic responses to unpredictable perturbations; however, electromyography is challenging. The aim of this study was to identify a measure to group sit-skiers according to their ability to control the trunk. Seated in their competitive sit-ski, 10 male and 5 female Paralympic sit-skiers received 6 forward and 6 backward unpredictable perturbations in random order. k-means clustered trunk position at rest, delay to invert the trunk motion, and trunk range of motion significantly into 2 groups. In conclusion, unpredictable perturbations might quantif…
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…
Paralympialaiset suomalaislehdissä : Barcelonan 1992 ja Lontoon 2012 paralympiauutisointi Helsingin Sanomissa, Iltalehdessä ja Urheilulehdessä
2015
Tutkimuksen tarkoituksena oli selvittää, millaista oli vuoden 1992 Barcelonan ja Lontoon 2012 paralympiauutisointi ja miten se muuttui 20 vuoden aikana. Tutkimuksessa tarkasteltiin Helsingin Sanomien ja Iltalehden urheilusivuja sekä Urheilulehden uutisointia paralympialaisista. Tutkimusaika rajattiin koskemaan päivä ennen ja jälkeen kisoja. Siten aineisto koostui yhteensä 53 paralympiajutusta. Tutkimus oli luonteeltaan laadullinen, mitä tuki määrällinen kuvaus paralympiauutisoinnista ja sen muutoksesta. Tutkimus pohjautui hermeneuttiseen tieteenfilosofiaan ja aineiston analysoinnissa käytettiin aineistolähtöistä sisällönanalyysia. Aineisto luokiteltiin Barcelonan kisoista viiteen luokkaan j…
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…
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…
