Urheilulukiolaisten siirtymä varhaisaikuisuuteen : identiteetin yhteys urheilun ja opintojen jatkamiseen

2023

Siirtymä varhaisaikuisuuteen tuo urheilijoiden elämään useita muutoksia, joiden vuoksi todennäköisyys lopettaa tavoitteellinen kilpaurheilu-ura kasvaa. Tämän tutkimuksen tarkoituksena oli selvittää, kuinka suuri osa urheilulukion vuonna 2015 aloittaneista nuorista jatkoi yhtäältä tavoitteellista kilpaurheilua ja toisaalta opintoja lukion jälkeen varhaisaikuisuudessa sekä olivatko sukupuoli ja lajimuoto (yksilö- vai joukkuelaji) yhteydessä jatkamiseen. Lisäksi tutkittiin, ennustivatko lukioaikaiset urheilija- ja opiskelijaidentiteetit kilpaurheilun ja opintojen jatkamista. Tutkimus on osa Jyväskylän yliopiston Winning in the long run -pitkittäistutkimusta, jonka seurantavaihe toteutettiin sy…

Metabolic health, menopause, and physical activity : a 4-year follow-up study

2022

Background In women, metabolic health deteriorates after menopause, and the role of physical activity (PA) in mitigating the change is not completely understood. This study investigates the changes in indicators of metabolic health around menopause and evaluates whether PA modulates these changes. Methods Longitudinal data of 298 women aged 48–55 years at baseline participating in the ERMA and EsmiRs studies was used. Mean follow-up time was 3.8 (SD 0.1) years. Studied indicators of metabolic health were total and android fat mass, waist circumference, waist-to-hip ratio (WHR), systolic (SBP) and diastolic (DBP) blood pressure, blood glucose, triglycerides, serum total cholesterol, and high…

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…

Exercise as stimulus for cartilage health in knee osteoarthritis

2018

Knee osteoarthritis (OA) is a leading cause of musculoskeletal pain and disability and has significant socio-economical costs globally. There is no known cure for OA. Therapeutic exercise has been shown to evoke acute positive posttreatment effects on pain and function. Even though cartilage degeneration is crucial in OA progression, there is sparse knowledge about exercise effects on osteoarthritic cartilage. The purpose of this study was to investigate the efficacy of aquatic resistance training on the estimated biochemical composition of tibiofemoral cartilage and the association between leisure time physical activity (LTPA) and tibiofemoral cartilage in postmenopausal women with mild kn…

Automaattisten mittalaitteiden käyttö vesistöseurannassa : esimerkkinä Jyväsjärven tutkimuslautta Aino

2011

Vesistöseurannan automatisointi lisää huomattavasti saatavilla olevan tiedon määrää, mutta samalla automaattisten aineistojen laadunvarmennuksen tärkeys korostuu. Jyväskylän yliopiston tutkimuslautta Aino mittaa jatkuvatoimisesti mm. veden happipitoisuuden ja lämpötilan vertikaaliprofiilia Jyväsjärvellä. Lautan tulosten luotettavuutta tutkittiin automaattisten mittalaitteiden sekä manuaalisen mittauksen avulla. Lautalla mitattiin myös virtausten suuntaa ja nopeutta ADCP-virtausmittarilla. Virtaustiedot tarkensivat kerrostumisen purkautumisen kuvaamiseen käytettyjä lukuja. Eri mittalaitteiden tuottamat happipitoisuustulokset poikkesivat merkitsevästi toisistaan. Hapen automaattisessa mittaam…

Impacts of Touch Screen Size, User Interface Design, and Subtask Boundaries on In-Car Task's Visual Demand and Driver Distraction

2020

Visual distraction by secondary in-car tasks is a major contributing factor in traffic incidents. In-car user interface design may mitigate these negative effects but to accomplish this, design factors’ visual distraction potential should be better understood. The effects of touch screen size, user interface design, and subtask boundaries on in-car task's visual demand and visual distraction potential were studied in two driving simulator experiments with 48 participants. Multilevel modeling was utilized to control the visual demands of driving and individual differences on in-car glance durations. The 2.5” larger touch screen slightly decreased the in-car glance durations and had a diminis…

Value Creation Behavior of Oura Ring Users in Social Media (Customer-dominant LOGIC)

2022

Smart devices such as self-trackers are being used by an ever-increasing number of exercisers to self-monitor their health. Users' interactions in social media can co-create and co-destruct the value and has a substantial impact on services. To investigate Oura Ring users' value creation behavior in the online context, we focus on customer-dominant logic and customer-to-customer (C2C) interaction. This paper proposes a conceptual framework, one of the first to investigate value creation in an empirical study in the context of well-being. Oura Ring is a smart ring that enables users to track their activities and sleep quality. To test relationships, structural equation modeling and Fuzzy Set…

Seuranta YVA- ja ympäristölupamenettelyissä

2015

The aim of environmental monitoring or follow-up is to detect changes in the environment over time and, if needed, to conduct preventive or mitigative actions based on monitoring results to minimize negative environmental effects. In the projects potentially causing significant environmental impacts, follow-up should consist of monitoring program presented in the environmental impact statement (EIS) and of monitoring obligations documented in the environmental permit. In this study, the quality and usability of monitoring programs presented in the EISs of Finnish peat production, crushed stone aggregate and dump projects were investigated. The study was conducted by a three-step content ana…
