Validity of long-term and short-term recall of occupational sitting time in Finnish and Chinese office workers
2020
Background As sedentary behavior is a global health issue, there is a need for methods of self-reported sitting assessment. The accuracy and reliability of these methods should also be tested in various populations and different cultural contexts. This study examined the validity of long-term and short-term recall of occupational sitting time in Finnish and Chinese subgroups. Methods Two cohort groups of office-based workers (58.6% female, age range 22–67 years) participated: a Finnish group (FIN, n = 34) and a Chinese group (CHI, n = 36). Long-term (past 3-month sitting) and short-term (daily sitting assessed on 5 consecutive days) single-item measures were used to assess self-reported occ…
Young Elderly and Digital Coaching : A Quantitative Intervention Study on Exercise Self-Efficacy
2020
Sport and wellness technology devices are becoming an increasingly relevant topic when discussing health and wellness. This study focuses on the use of a “digital coach”, within a specific population, young elderly people. This research explored how the use of a digital coach would affect self-efficacy related to physical activity and exercise among young elderly. Thisquantitative intervention study provided a digital coaching device to a group of young elderly people ranging from 61-78 in age for 10-weeks. It was found that a digital coach may be useful for this population, particularly in increasing their perceived confidence in exercising independently. However, the participants’ percept…
The Effects of Using a Mobile Wellness Application on Physical Activity Levels : A Four-Month Follow-Up Study Among Aged People
2020
Insufficient physical activity threatens people in older age. Thus, finding ways to support a physically active life in the older age is important. Digital wellness technologies have been presented as potential solutions, but in order for these solutions to be effective, research to gain insights on their use among aged people is needed. This study investigated how the use of a mobile wellness application for tracking physical activity affects physical activity levels among aged people. The physical activity levels were measured by using the IPAQ-E. The focus was on the first four months of use. The study was part of a research program in which groups of aged people take into use a mobile w…
Demographic Differences in the Effectiveness of a Physical Activity Application to Promote Physical Activity: Study Among Aged People
2021
The global population is ageing and simultaneously the life expectancy at older ages is improving. To support healthy and active aging, it is imperative to find solutions to support physical activity (PA) in older age. Digital wellness technologies are a potential solution, but in order for such technologies to be successful, research is needed to gain a better understanding on their use and effectiveness among aged people. To address this need, this study investigated the effectiveness of a physical activity application to promote PA behavior among aged people of different demographics (gender, age, education, marital status). PA levels were measured before taking the application into use …
Sustained Adoption of Systematic Physical Activity for Young Elderly : A Developed UTAUT Approach
2020
Health recommendations state that for young elderly systematic physical activi-ties at moderate intensity for at least 150 minutes per week are required to help them stay in good shape for their senior years. We have found that young elderly readily gets started with a physical activity (PA) program but there is some challenge to make them stay with this program. We have learned that a PA program should build on activities that users find meaningful and/or best suited for their history of PA and their present physical capacity. Support from dig-ital services to find meaningful and suitable programs can make a difference. We work out developments of the UTAUT to find drivers that could help …
Tieto- ja viestintätekniikan hyödyntäminen yläkoulun kemian opetuksessa
2013
Tämän pro gradu –tutkielman tarkoituksena oli kouluttaa Riihimäen kemian opettajia tieto- ja viestintätekniikan (TVT) pedagogisessa käytössä. Koulutus suunniteltiin kyselytutkimuksen vastausten perusteella. Tutkimuksessa haluttiin kartoittaa sitä, miten kemian opettajat hyödyntävät TVT:tä opetuksessaan ja minkälaisia toiveita heillä on räätälöitävälle täydennyskoulutukselle. Täydennyskoulutuksessa opettajat kokeilivat ChemSketch-visualisointiohjelman toimintaa ja he saivat koulutuksesta mukaansa harjoitustyöohjeen. Tuon harjoitustyöohjeen avulla opettajat voivat ottaa kyseisen ohjelman käyttöönsä omassa kemian opetuksessaan. Koulutuksessa opettajat tutustuivat myös mittausautomaatiolaitteen…
Quantification of cortical proprioceptive processing through a wireless and miniaturized EEG amplifier.
2022
Corticokinematic coherence (CKC) is computed between limb kinematics and cortical activity (e.g. MEG, EEG), and it can be used to detect, quantify and localize the cortical processing of proprioceptive afference arising from the body. EEG-based studies on CKC have been limited to lab environments due to bulky, non-portable instrumentations. We recently proposed a wireless and miniaturized EEG acquisition system aimed at enabling EEG studies outside the laboratory. The purpose of this work is to compare the EEG-based CKC values obtained with this device with a conventional wired-EEG acquisition system to validate its use in the quantification of cortical proprioceptive processing. Eleven hea…
Test−Retest Reliability of Isokinetic Ankle, Knee and Hip Strength in Physically Active Adults Using Biodex System 4 Pro
2023
Background: The isokinetic dynamometry is considered a gold standard in muscle strength testing. The reliability of lower limb isokinetic strength measurements has not been thoroughly evaluated. Objective: To examine the test−retest reliability of isokinetic ankle plantar and dorsiflexion, ankle inversion and eversion, knee extension and flexion and hip abduction and adduction strength in physically active adults using Biodex System 4 Pro. Methods: Peak torques (PTs) and average peak torques (APTs) of the dominant and nondominant lower limbs were tested twice in 19 physically active adults 7 to 14 days apart. Results: The intraclass correlation coefficients (ICC) values varied from excellen…
Automated water quality monitoring of humic lakes by using the optical properties of water
2016
Automated water quality monitoring (AWQM) is becoming increasingly common in lakes worldwide. The history of AWQM is relatively short and standard calibration procedures for the measured variables are largely yet to be established. The use of optical AWQM sensors, developed in oceanic environments, raises new questions on the diverse effects which humic compounds may have on the automated optical measurements in inlands waters. The focus of this thesis was to characterize the effects of coloured dissolved organic matter (CDOM) on optical in situ measurements of organic matter (OM) and chlorophyll (Chl) in lakes with varying humic content, and to use AWQM data as a part of traditional monito…
Applying UTAUT2 to Explain the Use of Physical Activity Logger Applications Among Young Elderly
2020
Digital wellness technologies have been proposed as a promising way to promote the levels of physical activity and to solve the prevalent problem of physical inactivity among elderly people. In this study, we propose and test a research model for explaining the acceptance and use of these technologies in the case of the young elderly segment (people aged 60–75 years) and physical activity logger applications. The proposed model is theoretically founded on UTAUT2, and it is empirically tested by using the data collected from 115 Finnish young elderly users of a physical activity logger application and analysed with partial least squares based structural equation modelling (PLS-SEM). We find …
