Can cycling with an E-bike improve fitness? : effect of access to an Electric Assisted Bicycle on cycling distance and cardiopulmonary fitness in ina…
2016
Masteroppgave folkehelsevitenskap - Universitetet i Agder 2016 Background: The aims of the present study were to assess the effect of an eight-month intervention with access to an Electric assisted bicycle (E-bike) on (1) the amount of E-biking, (2) changes in cardiopulmonary fitness and (3) to assess whether cycled distance was associated with changes in cardiopulmonary fitness, among inactive adults. Methods: Twenty-five inactive Norwegian adults (33 – 57 years of age, 72 % women), were recruited through convenience sampling. Participants were given an E-bike for eight (N = 23) or three (N = 2) months. Socio-demographic characteristics were reported with a questionnaire. Bicycle use was m…
Association of oral lichen planus with hepatic disorders and hepatocellular carcinoma:systematic review and meta-analysis
2023
Oral lichen planus (OLP) is a prevalent autoimmune chronic inflammatory disease of unknown etiology. The importance of the association between hepatic disease and OLP lies in the fact that many of these disorders (HC, HB, cirrhosis, hepatic steatosis) behave as risk factors for hepatocellular carcinoma. We searched PubMed, Embase, Web of Science, and Scopus for studies published before January 2022. We evaluated the quality of studies (Joanna Briggs Institute tool). We performed meta-analyses, investigated the heterogeneity between studies, and we also carried out subgroups, meta-regression, and small-study effects analyses. 146 studies (21,187 patients) were included in this study. Our stu…
Pyöräilytaidon oppimista selittävät yksilö-, ympäristö- ja tehtävätason tekijät 1950-2010-luvuilla
2021
Pyöräily on yksi suomalaisten yleisimmistä liikkumismuodoista. Yhteiskunnan tasolla pyöräilyn merkityksissä korostuvat väestön arkiliikunnan lisääminen ja kestävän liikenteen edistäminen. Suomalaislapsille pyöräilytaito mahdollistaa merkittävän itsenäisen liikkumisen tavan ja edesauttaa elinpiirin laajentumista. Pyöräilytaidon oppimiseen liittyvistä tekijöistä tiedetään kuitenkin hyvin vähän. Tämä tieto olisi tärkeää, jotta mahdollisimman monelle voitaisiin jo varhaisella iällä tarjota mahdollisuus omaksua pyöräilyn kautta fyysisesti aktiivinen ja ekologisesti kestävä elämäntapa. Tämän tutkimuksen tarkoitus oli selvittää, mitkä yksilö-, ympäristö- ja tehtävätekijät selittävät pyöräilytaidon…
Changes of Angiotensin Converting Enzyme (Ace) Levels During Activation of the Renin-Angiotensin-Aldosterone System (RAAs)
1987
The aim of this study was to evaluate the changes of ACE levels during RAAs activation induced by: 1) a continuous graded bicycle ergometer test performed in a group of 15 males health youths aged between 21 and 30 years, with average age of 25.8 +/- 2.85 years; 2) i.m. injection of 20 mg of frusemide in 11 health youths (10 males and 1 female), aged between 20 and 30 years, with average age of 24.09 +/- 2.77 years; 3) dialytic treatment in 25 patients (12 males and 13 females), suffering from chronic renal failure, aged between 26 and 68 years, with average age of 54 +/- 15.42 years. Plasmatic renin activity (PRA), aldosterone (ALD) and ACE levels were determined by RIA in basal conditions…
Muscle Free Fatty-Acid Uptake Associates to Mechanical Efficiency During Exercise in Humans
2018
Intrinsic factors related to muscle metabolism may explain the differences in mechanical efficiency (ME) during exercise. Therefore, this study aimed to investigate the relationship between muscle metabolism and ME. Totally 17 healthy recreationally active male participants were recruited and divided into efficient (EF; n = 8) and inefficient (IE; n = 9) groups, which were matched for age (mean ± SD 24 ± 2 vs. 23 ± 2 years), BMI (23 ± 1 vs. 23 ± 2 kg m−2), physical activity levels (3.4 ± 1.0 vs. 4.1 ± 1.0 sessions/week), and V˙O2peak (53 ± 3 vs. 52 ± 3 mL kg−1 min−1), respectively, but differed for ME at 45% of V˙O2peak intensity during submaximal bicycle ergometer test (EF 20.5 ± 3.5 vs. I…
Platelet Aggregation, Coagulation and Fibrinolysis at Rest and after Bicycle Ergometer Test in CHD
1980
Several observers have suggested that a dysfunction of dynamic balance between platelet aggregation, coagulation and fibrinolysis may be a factor in the pathogenesis of atherosclerosis. This dysfunction, presumably, is correlated with the atherosclerotic vascular lesions, that could reduce the parietal synthesis of heparan-sulphase, prostacyclin and plas minogen activator.
A School-Based Randomized Controlled Trial to Promote Cycling to School in Adolescents: The PACO Study
2021
This manuscript describes the rationale and protocol of a school-based randomized controlled trial called “Cycling and Walk to School” (PACO, by its Spanish acronym) that aims to promote cycling to and from school and physical activity (PA) in adolescents. This study will examine the effects of this intervention in cycling and active commuting to and from school (ACS), PA and several ACS-related factors based on self-determination theory (SDT) and a social-ecological model (SEM). A total of 360 adolescents attending six high schools (three experimental and three control) from three Spanish cities will participate in this randomized controlled trial. The intervention (four cycling sessions; …
Intra-Dialytic Electrostimulation of Leg Extensors May Improve Exercise Tolerance and Quality of Life in Hemodialyzed Patients
2011
Hemodialyzed (HD) patients with end-stage renal disease (ESRD) exhibit lower fitness as a consequence of chronic uremic changes that trigger various structural, metabolic, and functional abnormalities in skeletal muscles. The aim of this randomized study was to compare the effect of rehabilitation (RHB) training on a bicycle ergometer and electromyostimulation (EMS) of leg extensors in HD patients with ESRD. Thirty-two HD patients (18 men/14 women; mean age 61.1 ± 8.8 years) were randomized into three groups: (i) exercise training (ET; n = 11) on bicycle ergometer 2 × 20 min; (ii) EMS (n = 11) where stimulation (10 Hz) of leg extensors was applied for 60 min; and (iii) controls (CON; n = 10…
Infrastructural and Human Factors Affecting Safety Outcomes of Cyclists
2018
The increasing number of registered road crashes involving cyclists during the last decade, and the high proportion of road crashes resulting in severe injuries and fatalities among cyclists constitutes a global issue for community health, urban development, and sustainability. Nowadays, the incidence of many risk factors for road crashes of cyclists remains largely unexplained. Given the importance of this issue, the present study has been conducted with the aim of determining relationships between infrastructural, human factors and safety outcomes of cyclists. Objectives: This study aimed, first, to examine the relationship between key infrastructural and human factors present in cycling,…
