Socialt stöd, känsla av ensamhet och psykiska besvär bland finlandssvenska ungdomar
2021
I den här studien utforskades ifall det förekommer sociodemografiska skillnader i upplevelse av psykiska besvär, socialt stöd och känsla av ensamhet bland finlandssvenska ungdomar. Det undersöktes även ifall ungdomarnas upplevelse av psykiska besvär kan förklaras med familje-, kamrat- och klasskamratstöd samt känsla av ensamhet. Utöver det utforskades ifall samband mellan socialt stöd och psykiska besvär kan förklaras med känsla av ensamhet.
 Som datamaterial användes WHO:s skolelevstudie (WHO-Koululaistutkimus) från 2018 med ett deltagarantal på 599 svenskspråkiga elever från årskurs 5, 7 och 9 (Målder = 11,9/14,0/15,9; svarsprocent 38 %). Som statistiska analysmetoder användes Pearso…

2015
Le modele MobiSim a teste le lien entre la modification de l’offre de transport et l’exposition au bruit dans ses dimensions spatiales et temporelles, le test etant applique a l’agglomeration de Besancon. C’est la desynchronisation des activites, le report modal et les changements dans les grilles horaires des transports collectifs qui produisent des effets reduisant ou bien augmentant l’exposition au bruit selon les lieux et les moments, les populations concernees etant elles-memes socialement diversifiees.
Will women outrun men in ultra-marathon road races from 50 km to 1,000 km?
2014
Abstract It has been assumed that women would be able to outrun men in ultra-marathon running. The present study investigated the sex differences in running speed in ultra-marathons held worldwide from 50 km to 1,000 km. Changes in running speeds and the sex differences in running speeds in the annual fastest finishers in 50 km, 100 km, 200 km and 1,000 km events held worldwide from 1969–2012 were analysed using linear, non-linear and multi-level regression analyses. For the annual fastest and the annual ten fastest finishers, running speeds increased non-linearly in 50 km and 100 km, but not in 200 km and 1,000 km where running speeds remained unchanged for the annual fastest. The sex diff…
Sex and age-related differences in performance in a 24-hour ultra-cycling draft-legal event - a cross-sectional data analysis
2014
International audience; BackgroundThe purpose of this study was to examine the sex and age-related differences in performance in a draft-legal ultra-cycling event.MethodsAge-related changes in performance across years were investigated in the 24-hour draft-legal cycling event held in Schötz, Switzerland, between 2000 and 2011 using multi-level regression analyses including age, repeated participation and environmental temperatures as co-variables.ResultsFor all finishers, the age of peak cycling performance decreased significantly (β = −0.273, p = 0.036) from 38 ± 10 to 35 ± 6 years in females but remained unchanged (β = −0.035, p = 0.906) at 41.0 ± 10.3 years in males. For the annual faste…
The effects of course length on freestyle swimming speed in elite female and male swimmers - a comparison of swimmers at national and international l…
2013
Abstract Freestyle swimming performance over 50 m, 100 m, 200 m, 400 m, 800 m and 1,500 m was compared on short (25 m) and long (50 m) course for 92,196 national swimmers (i.e. annual high score list Switzerland) and 1,104 international swimmers (i.e. finalists FINA World Championships) from 2000 to 2012. National and international swimmers of both sexes were on average 2.0 ± 0.6% faster on short than on long course. Sex-related differences in swimming speed were greater on short than on long course for international and national swimmers from 50 m to 800 m. Freestyle swimming performance improved across years for international swimmers in both short- and long-course whereas only male natio…
Sex-related differences and age of peak performance in breaststroke versus freestyle swimming
2013
Abstract Background Sex-related differences in performance and in age of peak performance have been reported for freestyle swimming. However, little is known about the sex-related differences in other swimming styles. The aim of the present study was to compare performance and age of peak performance for elite men and women swimmers in breaststroke versus freestyle. Methods Race results were analyzed for swimmers at national ranked in the Swiss high score list (during 2006 through 2010) and for international swimmers who qualified for the finals of the FINA World Swimming Championships (during 2003 through 2011). Results The sex-related difference in swimming speed was significantly greater…
Nation related participation and performance trends in ‘Ironman Hawaii’ from 1985 to 2012
2014
Abstract Background This study examined participation and performance trends in ‘Ironman Hawaii’ regarding the nationality of the finishers. Methods Associations between nationalities and race times of 39,706 finishers originating from 124 countries in the ‘Ironman Hawaii’ from 1985 to 2012 were analyzed using single and multi-level regression analysis. Results Most of the finishers originated from the United States of America (47.5%) followed by athletes from Germany (11.7%), Japan (7.9%), Australia (6.7%), Canada (5.2%), Switzerland (2.9%), France (2.3%), Great Britain (2.0%), New Zealand (1.9%), and Austria (1.5%). German women showed the fastest increase in finishers (r2 = 0.83, p < …
Analysis of sex differences in open-water ultra-distance swimming performances in the FINA World Cup races in 5 km, 10 km and 25 km from 2000 to 2012
2014
International audience; BACKGROUND: The present study investigated the changes in swimming speeds and sex differences for elite male and female swimmers competing in 5 km, 10 km and 25 km open-water FINA World Cup races held between 2000 and 2012. METHODS: The changes in swimming speeds and sex differences across years were analysed using linear, non-linear, and multi-level regression analyses for the annual fastest and the annual ten fastest competitors. RESULTS: For the annual fastest, swimming speed remained stable for men and women in 5 km (5.50 ± 0.21 and 5.08 ± 0.19 km/h, respectively), in 10 km (5.38 ± 0.21 and 5.05 ± 0.26 km/h, respectively) and in 25 km (5.03 ± 0.32 and 4.58 ± 0.27…
Changes in transition times in ‘Ironman Hawaii’ between 1998 and 2013
2014
International audience; BackgroundRecent findings showed that elite Ironman triathletes competing in ‘Ironman Hawaii’ improved both split and overall race times. The present study investigated whether elite athletes also improved in transition time (i.e. time needed between disciplines for changing clothes and equipment).MethodsChanges in split times, overall race times and transition times (i.e. expressed in absolute and relative terms) in the annual fastest competing in ‘Ironman Hawaii’ were investigated using linear, non-linear and multi-level regression analyses. To detect a potential difference in transition times between different race distances, we compared transition times in ‘Ironm…
Swimming performances in long distance open-water events with and without wetsuit.
2013
International audience; BACKGROUND: Existing literature showed improved swimming performances for swimmers wearing wetsuits competing under standardized conditions in races held in pools on short to middle distances. Data about the influence of wetsuits on swimming performances in long and ultra-long open-water swimming races are missing. It is unknown whether the benefit of wearing wetsuits is comparable in men and women. The aim of this study was to investigate the influence of wearing a wetsuit on open-water swimming performances at the 26.4 km 'Marathon Swim in Lake Zurich' in Lake Zurich, Switzerland, and the 3.8 km Lake Ontario Swim Team-Race (LOST-Race) in Lake Ontario, Canada.
