Effect of childhood developmental coordination disorder on adulthood physical activity; Arvo Ylppö longitudinal study
2022
Publisher Copyright: © 2022 The Authors. Scandinavian Journal of Medicine & Science In Sports published by John Wiley & Sons Ltd. Individuals at risk of Developmental Coordination Disorder (DCD) have low levels of physical activity in childhood due to impaired motor competence; however, physical activity levels in adulthood have not been established. This study sought to determine the impact of DCD risk on physical activity levels in adults using accelerometry measurement. Participants (n = 656) from the Arvo Ylppö Longitudinal Study cohort had their motor competence assessed at the age of five years, and their physical activity quantified via device assessment at the age of 25 years. Betwe…
Changes in sprint performance and sagittal plane kinematics after heavy resisted sprint training in professional soccer players
2019
Background Sprint performance is an essential skill to target within soccer, which can be likely achieved with a variety of methods, including different on-field training options. One such method could be heavy resisted sprint training. However, the effects of such overload on sprint performance and the related kinetic changes are unknown in a professional setting. Another unknown factor is whether violating kinematic specificity via heavy resistance will lead to changes in unloaded sprinting kinematics. We investigated whether heavy resisted sled training (HS) affects sprint performance, kinetics, sagittal plane kinematics, and spatiotemporal parameters in professional male soccer players.…
Coordinating collaborative writing in an online environment
2018
This study investigated how university students (n = 28) coordinated their collaborative online writing and what kinds of coordination profiles were found among the students. Further, the study examined the quality of the essays produced by groups of students varying in their combinations of coordination profiles. Students’ written comments on their writing processes (n = 583) were divided into episodes focusing on coordination. Eight different categories of collaborative activities during online collaboration were found. The students’ joint essays (n = 9) were evaluated as high, moderate and low according to the number of topics, key concepts, and integration of Internet sources in the ess…
Association between developmental coordination disorder or low motor competence, and risk of impaired bone health across the lifespan: protocol for a…
2020
OBJECTIVE: This systematic review will assess the association between developmental coordination disorder and low motor competence, and impairments in bone health across the lifespan. INTRODUCTION: Individuals with developmental coordination disorder tend to have a pattern of physical activity associated with bone health impairments. Preliminary studies have found impairments in bone health measures, including fractures, throughout the lifespan with potential public health ramifications. As studies in this area are of small samples across wide age ranges no comprehensive picture of bone health in this group has been formed, hindering action. A systematic review is needed to determine the po…
Koordinaatio, ketteryys ja dynaaminen tasapaino suomalaisilla urheiluseurassa urheilevilla nuorilla
2016
Liikuntataitojen oppiminen on yksi liikuntakasvatuksen tärkeimmistä tavoitteista. Hyvät lii-kuntataidot auttavat liikunnallisen elämäntavan omaksumisessa ja arjessa selviytymisessä. Tämän tutkimuksen tavoitteena on tutkia suomalaisten urheiluseurassa urheilevien lasten ja nuorten koordinaatiota, ketteryyttä ja dynaamista tasapainoa KTK-testillä (Körperkoor-dinationstest für Kinder) mitattuna. Tutkimuksen aineistona käytettiin sekundaariaineistoa, jossa 8–19-vuotiaita (n=1097, poikia 364, tyttöjä 733, ka 12,58 ± 1,80 vuotta) urheiluseurassa urheilevia lapsia ja nuoria oli mitattu KTK-testillä. Aineisto kerättiin syksyn 2013 ja kevään 2014 aikana ja kyseessä on poikkileikkaustutkimus. Aineist…
Alakoulun opettajat motoriikan arvioijina
2015
Kuikka, Henna 2015. Alakoulun opettajat motoriikan arvioijina. Kasvatustieteen pro gradu –tutkielma. Jyväskylän yliopisto. Opettajankoulutuslaitos. Tämän tutkimuksen tarkoituksena oli selvittää, löytyvätkö opettajan arvioimana ne oppilaat, joilla on kehityksellisiä koordinaatiohäiriöitä eli motorisen oppimisen vaikeuksia ja kuinka luotettava Motoriikan havainnointilomake (MOQ-T) on tunnistettaessa niitä lapsia, joilla haasteita opettajan mukaan on havaittavissa. Tutkimus toteutettiin yhteistyössä Mukaan – liikun, opin, osallistun –tutkimushankkeen kanssa. Mukaan- liikun, opin, osallistun – hanke (2012 – 2014) toteutetaan yhteistyössä Suomen CP-liiton, Niilo Mäki Instituutin, Jyväskylän ylio…
Clausal coordination in Finnish Sign Language
2016
This paper deals with the coordination of clauses in Finnish Sign Language (FinSL). Building on conversational data, the paper first shows that linking in conjunctive coordination in FinSL is primarily asyndetic, whereas in adversative and disjunctive coordination FinSL prefers syndetic linking. Secondly, the paper investigates the nonmanual prosody of coordination: nonmanual activity is shown both to mark the juncture of the coordinand clauses and to draw their contours. Finally, the paper addresses certain forms of clausal coordination in FinSL that are sign language-specific. It is suggested that the sign language-specific properties of coordination are caused both by the fact that signe…

MATLAB codes implementing the generalized cross-wavelet transform (GXWT) algorithm described in the paper "Analyzing multidimensional movement interaction with generalized cross-wavelet transform" (Toiviainen & Hartmann, 2021). Basic workflow for multivariate (time by channel) signals d1 and d2: [w1,f] = cwtensor(d1,FS,MINF,MAXF); [w2,f] = cwtensor(d2,FS,MINF,MAXF); [xs p1 p2] = getxwt(w1,w2); NOTE: cwtensor.m requires the Wavelet Toolbox for MATLAB.
Coordination Complexes of a Neutral 1,2,4-Benzotriazinyl Radical Ligand: Synthesis, Molecular and Electronic Structures, andMagnetic Properties
2015
A series of d-block metal complexes of the recently reported coordinating neutral radical ligand 1-phenyl-3-(pyrid-2-yl)-1,4-dihydro-1,2,4-benzotriazin-4-yl (1) was synthesized. The investigated systems contain the benzotriazinyl radical 1 coordinated to a divalent metal cation, MnII, FeII, CoII, or NiII, with 1,1,1,5,5,5-hexafluoroacetylacetonato (hfac) as the auxiliary ligand of choice. The synthesized complexes were fully characterized by single-crystal X-ray diffraction, magnetic susceptibility measurements, and electronic structure calculations. The complexes [Mn(1)(hfac)2] and [Fe(1)(hfac)2] displayed antiferromagnetic coupling between the unpaired electrons of the ligand and the meta…
Individual, Family, and Environmental Correlates of Motor Competence in Young Children: Regression Model Analysis of Data Obtained from Two Motor Tes…
2020
Physical activity and motor competence (MC) have been considered to be closely related and prevent childhood obesity. The aim of the study was two-fold: to examine MC measured with two different tools in relation to individual, family, and environmental correlates and to investigate gender differences in MC. The Test of Gross Motor Development-Third Edition (TGMD-3) was administered to three- to seven-year-old children (n = 945), while the Kö
