Polkujuoksu : juoksuharrastus kohtaa luontokokemuksen

2017

Juoksuharrastuksesta eriytynyt polkujuoksu on suosiotaan vahvasti 2010-luvulla kasvattanut liikuntamuoto. Käsillä oleva tutkimus on ensimmäinen suomalaista polkujuoksuharrastusta kartoittava liikuntasosiologinen tutkimus. Polkujuoksuharrastusta taustoitetaan teoreettisesti vapaa-ajan elämäntavan, luontoliikunnan sekä kestävyysliikunnan ilmiönä. Tutkimukselle on asetettu neljä tutkimuskysymystä: 1) Ketkä harrastavat polkujuoksua? 2) Miten polkujuoksua harrastetaan? 3) Kuinka kiinnittyneitä polkujuoksun harrastajat ovat harrastukseensa? 4) Miten polkujuoksijat haluaisivat liikuntamuodon kehittyvän? Polkujuoksun harrastajakartoitus toteutettiin määrällisenä tutkimuksena. Tutkimusta varten laad…

WATCHING PEOPLE: ALGORITHMS TO STUDY HUMAN MOTION AND ACTIVITIES

2020

Nowadays human motion analysis is one of the most active research topics in Computer Vision and it is receiving an increasing attention from both the industrial and scientific communities. The growing interest in human motion analysis is motivated by the increasing number of promising applications, ranging from surveillance, human–computer interaction, virtual reality to healthcare, sports, computer games and video conferencing, just to name a few. The aim of this thesis is to give an overview of the various tasks involved in visual motion analysis of the human body and to present the issues and possible solutions related to it. In this thesis, visual motion analysis is categorized into thr…

Perceived Well-being Effects During the Implementation of a Self-tracking Technology

2016

In recent years, both individuals and the healthcare sector have become more interested to measure and improve health and well-being by using different selftracking technologies. However, the number of studies concerning the experiences that people have with these technologies is still rather limited. This study investigates the expectations and perceived short-term effects of using self-tracking technologies on users’ well-being. The focus is on the first weeks of usage i.e., the implementation phase. The study is qualitative in nature and based on thematic analysis of ten semistructured interviews. The results reveal that the perceived well-being effects of using a self-tracking technolog…

User perceptions on the privacy of health information

2016

Activity trackers have become more common and they enable the collection of information about an individual’s physical activities and health. Traditionally a person’s health information was stored in the health care provider’s databases, but now health information is being stored in multiple services. This change has brought new ways to utilize technologies in the area of health and wellness, but at the same time questions have surfaced concerning the privacy of an individual’s information. This thesis discusses a study regarding the user perception on the privacy and sensitivity of health information collected with wearable devices. The study also explored the user perception on health inf…

Accuracy of Computer-Aided Dynamic Navigation Compared to Computer-Aided Static Navigation for Dental Implant Placement: An In Vitro Study

2019

Aim: To analyze the accuracy capability of two computer-aided navigation procedures for dental implant placement. Materials and Methods: A total of 40 dental implants were selected, which were randomly distributed into two study groups, namely, group A, consisting of those implants that were placed using a computer-aided static navigation system (n = 20) (guided implant (GI)) and group B, consisting of those implants that were placed using a computer-aided dynamic navigation system (n = 20) (navigation implant (NI)). The placement of the implants from group A was performed using surgical templates that were designed using 3D implant-planning software based on preoperative cone-beam computed…

Critical Experiences During the Implementation of a Self-tracking Technology

2016

Emerging technologies have brought several new ways to track, measure and evaluate own activity. Well-being, nutrition, physical training, mood, and sleep are a few of the various measures that can be self-tracked by different technological solutions. At the same time, people are becoming more interested in themselves and their own well-being, and constant tracking of own activities is getting more and more popular both on individual level as well as in general healthcare. This study examines critical experiences that occur during the implementation phase of the innovation-decision process and their influence to adopting or rejecting a self-tracking technology. The study is qualitative in n…

Moving from intention to behaviour: a randomised controlled trial protocol for an app-based physical activity intervention (i2be).

2022

IntroductionEfficacy tests of physical activity interventions indicate that many have limited or short-term efficacy, principally because they do not sufficiently build on theory-based processes that determine behaviour. The current study aims to address this limitation.Methods and analysisThe efficacy of the 8-week intervention will be tested using a three-condition randomised controlled trial delivered through an app, in women with a prior hypertensive pregnancy disorder. The intervention is based on the integrated behaviour change model, which outlines the motivational, volitional and automatic processes that lead to physical activity. The mechanisms by which the behaviour change techniq…

Non‐uniform displacement within ruptured Achilles tendon during isometric contraction

2021

The purpose of this study was investigate tendon displacement patterns in non‐surgically treated patients 14 months after acute Achilles tendon rupture (ATR) and to classify patients into groups based on their Achilles tendon (AT) displacement patterns. Twenty patients were tested. Sagittal images of AT were acquired using B‐mode ultrasonography during ramp contractions at a torque level corresponding to 30% of the maximal isometric plantarflexion torque of the uninjured limb. A speckle tracking algorithm was used to track proximal‐distal movement of the tendon tissue at 6 antero‐posterior locations. Two‐way repeated measures ANOVA for peak tendon displacement was performed. K‐means cluster…

The Development and Precision of a Custom-Made Skitester

2021

In the sport of cross-country skiing, equipment has a direct influence on results. Ski teams do extensive testing of different ski base grinds and products on a yearly basis. To achieve reliable results, the quality of methods used for testing skis needs to be taken in to account in addition to factors including the physical characteristics of testing personnel and changes in weather conditions. The aim of this study was to introduce a custom-made skitester, that was developed for testing skis on real snow, in laboratory conditions, and to evaluate its precision. The current skitester is capable of glide testing both classic and skate skis as well as kick simulation for the testing of grip …
