The Associations Between Leisure-Time Physical Activity and Academic Performance: A Twin Study

2021

Background: Both genetic and environmental influences have been shown to contribute to the association between physical activity and overall academic performance. The authors examined whether leisure-time physical activity (LTPA) shares genetic and environmental variances between spelling, essay writing, reading aloud, reading comprehension, and mathematics in early adolescence. Moreover, they investigated whether genetic polymorphisms associated with physical activity behavior affect these academic skills. Methods: Participants were 12-year-old Finnish twins (n = 4356–4370 twins/academic skill, 49% girls). Academic skills were assessed by teachers, and LTPA was self-reported. Polygenic sco…

Estimating Programming Exercise Difficulty using Performance Factors Analysis

2020

This Work in Progress Paper studies student and exercise modelling based on pass/fail log data gathered from an introductory programming course. Contemporary education capitalizes on the communications technology and remote study. This can create distance between the teacher and students and the resulting lack of awareness of the difficulties students encounter can lead to low student satisfaction, dropout and poor grades. In many cases, various technological solutions are used to collect individual exercise submissions, but there are little resources for indexing or modelling the exercises in depth. Exercise specific feedback from students may not be easily obtainable either. In the presen…

Leisure-time physical activity and participation in organized sports : changes from 1985-2014 in Finland and Norway

2019

Participation in organized sports is a popular and important part of the lives of children and adolescents and is associated with improved psychological and social health, as well as an increased likelihood of meeting physical activity (PA) recommendations. Changes in modern society, including increased car ownership and use of technology and electronic media, have led to an additional focus on the importance of health‐enhancing PA among children and adolescents. The aim of this article was to study the secular changes in self‐reports of participation in organized sports clubs and leisure‐time vigorous physical activity (LVPA), and whether the relationship between participation in organized…

Knee arthroplasty until age 60 : role of sports and other injuries

2019

BACKROUND: The primary aim of the study was to investigate how total knee arthroplasty (TKA) patients with underlying injuries differ in injury type and physical activity after the arthroplasty. METHODS: A questionnaire was sent to TKA patients, < 60 years at surgery, and knee injury as the cause of knee OA. The final study group consisted of 70 patients. RESULTS: Average age of patients at TKA was 51.8 years (Standard Deviation [SD] 5.2), and at follow-up 57.6 years (SD 6.5). Of the injuries, 26% were sports-related, 29% had occurred at work, 23% in traffic accidents, and 13% during leisure-time (no sports-related). Sports-related injuries had occurred at younger ages than others had (mean…

Power Loading-Induced Fatigue is Influenced by Menstrual Cycle Phase

2022

Purpose To examine the effects of fatiguing power-loading on neuromuscular properties, force production, and metabolic capacities during four phases of the menstrual cycle (MC); menstruation (M), mid-follicular (mid FOL), ovulation (OV), and mid-luteal (mid LUT). Methods Sixteen eumenorrheic women performed sessions of maximal explosive leg press (2x10 at 60%1RM load with 2 min recovery between sets). Serum hormones and neuromuscular responses were measured. Results The loading protocol significantly decreased power (between -14.2% and -12.5%; p < 0.001) and maximal force production (between MVC; -15.0% and -7.8%; p < 0.001–0.05), while decreasing activation level (between AL; -6.9% and -2.…

Global Trends in Scientific Research on Pediatric Obesity

2022

(1) Introduction: The aim of this study was to analyze scientific production, collaboration among countries, and research topics focusing on pediatric obesity. (2) Methods: The papers that were included in the study were retrieved from the Web of Science Core Collection from Clarivate Analytics. A bibliometric analysis of several focuses, including journals of publication, subject categories, most frequent author keywords, and journal impact factors, was conducted. Social network analysis was used to recognize collaboration groups between countries and the co-occurrences of author keywords. (3) Results: A total of 12,171 research articles were published in 2036 journals classified under a v…

Digital sports games and their players : playing motivations and player's assessment of the effects of playing

2012

Tämän tutkimuksen tarkoitus oli määrittää digitaalisten liikuntapelien pelaajien pelaamisen motiiveja sekä syitä pelata digitaalisia liikuntapelejä. Tämän lisäksi tarkoituksena oli selvittää pelaamisen seurauksia pelaajille. Erityisen tärkeää oli analysoida pelaajien henkilökohtaisia kokemuksia pelaamisen vaikutuksista kehoon ja jokapäiväiseen elämään. Tämä laadullinen tutkimus perustuu kahdeksan hengen kyselyn vastauksiin. Strukturoidut kyselyt analysoitiin ja niiden perusteella muodostettiin neljä eri digitaalisten liikuntapelien pelaajaprofiilia. Tulokset osoittavat, että vastaajien fyysinen tausta on hyvin erilainen. Osa vastaajista oli aktiivisia liikkujia, osa ei ollut harrastanut lii…

Cyber security exercise : Literature review to pedagogical methodology

2019

This paper is a literature review, where we try to find out pedagogical principles has used in different virtual or simulated industry learning environments. The purpose is to use these findings to create in the future a new model for teaching in cyber security exercises. Cyber security exercises are the major service at JYVSECTEC - Jyväskylä Security Technology, cyber security research, training and development center in Finland [1]. JYVSECTEC Cyber security exercises are executed in real life simulation environment, RGCE (Realistic Global Cyber Environment) [1]. It provides the same functionality as the real Internet, but it is isolated from the real Internet and fully controlled by JYVSE…
