Impact of physical effort on von Willebrand factor’s activity and concentration in blood
2020
Background and Study Aim: Physical exercise causes a wide range of physiological changes including the production and release of haemostasis regulating factors. One of these factors is von Willebrand factor (vWf)- a glycoprotein responsible for both platelet adhesion and coagulation cascade. Material and Methods: The impact of physical effort on von Willebrand’s factor’s concentration (vWf:Ag) and activity (vWf:CBA) underwent analysis in the group of 42 people (22 men and 20 women) aged 19-22 (mean 20, SD 8 months). Physical effort was induced by 35 minutes of swimming in indoor swimming pool. Results: Physical exercise in form of swimming causes an increase of Willebrand’s factor’s concent…
Breaststroke swimmer's knee
1980
The cause of the breaststroke swimmer's knee with medial pain of the knee joint has not been clearly identified. Breaststroke swimmers with knee pain were, therefore, examined arthros copically. None showed any other disorders of their knees than medial synovitis in seven of nine swimmers. Since structural abnormalities could be ruled out, biomechanical analyses utiliz ing cinematographic techniques were used to study patients swimming in a special flume with the speed set at 90% of their best competitive performance. The results indicate that the extension and flexion and also in some cases the hip abduction and adduction movements of the whip kick were performed with high peak angular ve…
Prenatal exposure to diazepam and alprazolam, but not to zolpidem, affects behavioural stress reactivity in handling-naïve and handling-habituated ad…
2002
A gentle long-lasting handling produces persistent neurochemical and behavioural changes and attenuates the impairment in the behavioural reactivity to novelty induced by the prenatal exposure to diazepam (DZ) in adult male rat progeny. This study investigated the consequences of a late prenatal treatment with three GABA/BDZ R agonists (DZ) alprazolam (ALP) and zolpidem (ZOLP)), on different stress-related behavioural patterns, in non-handled (NH), short-lasting handled (SLH) and long-lasting handled (LLH) adult male rats exposed to forced swim test (FST), acoustic startle reflex (ASR) and Vogel test (VT). The effects on motor activity were evaluated in the open field and in the Skinner box…
Resilience and Precompetitive Anxiety in swimmers of school age. A descriptive study.
2018
El objetivo de este trabajo fue explorar la influencia que el género, la edad, los años nadando y la resiliencia tienen sobre la ansiedad competitiva en una muestra de nadadores escolares (N=74). La resiliencia fue medida con una adaptación española del CD-RISC, mientras que para medir la ansiedad competitiva se utilizó la versión española del CSAI-2R. También se exploraron los datos sociodemográficos (edad, sexo, años nadando y nivel competitivo). Para el análisis de datos se realizaron pruebas no paramétricas (Kruskal-Wallis y U de Mann Whitney), además de correlación de Pearson. Los resultados mostraron que el género, la edad de los nadadores y los años nadando no guardan relación con lo…
Uimahallipalveluiden tuottamismallit kuntaorganisaatioissa esimiesnäkökulmasta
2017
Työn tarkoituksena on selvittää uimahallipalveluiden tuottamismalleja kuntaorganisaatioissa. Tutkimuksen kohteena ovat uimahallien hallinto ja laitosteknisten palveluiden tuottamismallit. Laitosteknisillä palveluilla tarkoitetaan kiinteistön ja allastekniikan ylläpitoon liittyvää toimintaa. Tutkimus kohdistuu yhteen palvelutuotannon osaan, uimahallipalveluihin, jotka ovat keskeinen kunnallisten liikuntapalveluiden toiminto. Näin pystyttiin luomaan riittävän syvällinen katsaus yhteen osa-alueeseen, joka kuitenkin kertoo myös laajemmasta kokonaisuudesta. Tutkimusta varten haastateltiin Jyväskylän, Järvenpään, Keravan, Kouvolan, Turun, Tuusulan, Raision ja Urheiluhallit Oy:n (Helsinki) uimahal…
Perceptions of sport injuries of young elite swimmers
2012
Mari Lehtinen, 2012. Perceptions of sport injuries of young elite swimmers. Department of Sport Sciences. University of Jyväskylä. Master’s Thesis of Sport and Exercise Psychology. 64 pages. Sport injuries occur at all levels of sport. Sport injury can limit or end athlete´s career. It is important to find out ways how sport psychology can prevent and treat sport in juries. This can be done for example, by having impacts on mental and physical capabilities of athletes. Aim was to study rehabilitation process of injured swimmers according to the sport psychology point of view. The aim was to study experiences of elite swimmers during recovery process. Secondly, this study helped to describe …
Effects of progressive aquatic resistance training on symptoms and quality of life in women with knee osteoarthritis: A secondary analysis.
2020
Abstract Objective: To conduct a secondary analysis to study the effects, those 4 months of aquatic resistance training have on self‐assessed symptoms and quality of life in post‐menopausal women with mild knee osteoarthritis (OA), after the intervention and after a 12‐month follow‐up period. Methods: A total of 87 post‐menopausal volunteer women, aged 60‐68 years, with mild knee OA were recruited in a randomized, controlled, 4‐month aquatic training trial (RCT) and randomly assigned to an intervention (n = 43) and a control (n = 44) group. The intervention group participated in 48 supervised aquatic resistance training sessions over 4 months while the control group maintained their usual l…
How University Students Assess Their Water Skills.
2022
The aim of this study was to determine the gender differences between students' actual and perceived water abilities, how respondents assess risk in the described situations, and whether there are gender differences for those situations. The cross-sectional study was conducted on 150 students aged 19–20 years (males, n = 88; females, n = 62) from the faculty of sport and physical education, University of Novi Sad. Using calculated frequencies and estimates, students' self-assessment and actual measures of their swimming and survival skills and their perceived risk of drowning are described. Based on the results, Mann-Whitney U tests were applied. The differences between independent variable…
