Associations of physical activity in detailed intensity ranges with body composition and physical function : a cross-sectional study among sedentary …
2020
Background Physical activity is crucial to maintain older adults’ health and functioning, but the health benefits of particular activity intensities remain unclear. The aim of this cross-sectional study was to peruse the distribution of physical activity, and to investigate the associations of particular physical activity intensities with body composition and physical function among older adults. Methods The sample comprised of 293 community-dwelling sedentary or at most moderately active older adults (42% men, mean age 74 ± 4 years). Physical activity was measured with a hip-worn tri-axial accelerometer over seven consecutive days, and investigated in detailed intensity range and in catego…
Vertikaalihypyn korkeuden arviointi 3D-kiihtyvyysanturilla ja lajinomaisen kuormituksen vaikutukset hyppyyn
2016
Sensoreihin perustuvat menetelmät ovat yleistyneet urheilutestauksessa viime vuosina. Tarkoituksena oli selvittää hyppääjän kenkään kiinnitettävään 3D-kiihtyvyysanturiin perustuvan menetelmän validiteettia vertikaalihypyn korkeuden arvioinnissa. Voimalevyn lentoaikamenetelmää käytettiin kiihtyvyysanturimenetelmän validiteettianalyysissä ja lajikohtaisten kuormitusasetelman vertikaalihypyt arvioitiin kiihtyvyysanturimenetelmällä. Hyppysarjojen korkeimmat hypyt arvioitiin lisäksi voimalevyn lähtönopeusmenetelmällä. Kiihtyvyysanturimenetelmässä käytettiin urheilijan kenkään kiinnitettävää The Stride Sensor Bluetooth® Smart (Polar Electro Oy, Kempele, Suomi) -sensoria. Hyppytestit suoritettiin …
Ice hockey goaltending : physiological loading and game analysis
2012
ABSTRACT Kilpivaara, P. 2012. Ice hockey goaltending: physiological loading and game analysis. Master’s thesis in Science of Sport Coaching and Fitness Testing. Department of Biology and Physical activity, University of Jyväskylä. 77 pp. The ice hockey goaltenders have been acknowledged as crucial components of team success in ice hockey. The goaltending position differs greatly from forwards and defensemen and is therefore a very specialized position in ice hockey. As of yet, there has not been any in depth research directed to examine the goaltending game performance. Therefore, this study aimed to investigate the physiological loading of playing a game and also the action and performance…
End Users’ Perspective of Performance Issues in Google Play Store Reviews
2022
The success of mobile applications is closely tied to their performance which shapes the user experience and satisfaction. Most users often delete mobile apps from their devices due to poor performance indicating a mobile app’s failure in the competitive market. This paper performs a quantitative and qualitative analysis and investigates performance-related issues in Google Play Store reviews. This study has been conducted on 368,704 reviews emphasizing more 1- and 2-star reviews distributed over 55 Android apps. Our research also reports a taxonomy of 8 distinct performance issues obtained using manual inspection. Our findings show that end-users recurrently raised Updation (69.11%), Respo…
Effects of a 10-day high-intensity interval training mesocycle on physical performance in male judo athletes
2020
Judo is an Olympic combat sport where the competition emphasizes several consecutive 20-30 seconds high-intensity efforts interspersed by short recovery periods. High-intensity block training has been found to be an efficient way to develop physical performance, wherein shorter training periods are focused on developing one or two chosen physical abilities. The purpose of this study was to investigate the effects of a 10-day high-intensity interval training period on the performance in male judo athletes. The study included pre and post-tests as well as a 10-day training intervention. The subjects were 19-28 years old men who had competed at least at the Nordic level during the last year (n…
Effects of an 8-day field training on body composition, serum hormone concentrations and maximal force production in military conscripts
2015
Savolainen, S. 2015. Effects of an 8-day field training on body composition, serum hormone concentrations and maximal force production in military conscripts, 64p. University of Jyväskylä. Department of Biology of Physical Activity. Science of Sports Coaching and Fitness Testing. The aim of this study was to examine physiological consequences on 8-day strenuous military field exercise. 26 men (20 ± 1 yrs, 53,7 ± 4,5ml/kg/min, 178,4 ± 7,2cm, 71,2 ± 7,2kg) in the end of their military service participated in the study. The research data was collected in five testing day (pre1, pre2, middle, post and follow-up); body composition, physical performance and basal blood levels were measured. The c…

Reliability, validity and performance determinants of the military simulation test for the assessment of anaerobic performance in soldiers
2020
Introduction: Measurements of physical fitness have been identified as one of the most important research priorities in the military. Currently, the physical fitness tests of The Finnish Defence Forces (FDF) do not include a valid and reliable anaerobic test. In order to develop job-related task simulation tests, the purpose of the study was to determine the reliability and validity of a high-intensity military simulation test (MST), which is designed to assess the task-specific anaerobic performance of soldiers. The MST includes typical combat-related maneuvers while wearing a 20 kg combat load. Methods: 22 male cadets (22.5 ± 0.8 years) volunteered to participate. The MST was performed th…
Effect of 12-month supervised, home-based physical exercise on functioning among persons with signs of frailty : Randomized Controlled Trial
2021
Objectives To investigate the effects of a 12-month home-based exercise program on functioning and falls among persons with signs of frailty. Design A randomized controlled trial with a 1:1 allocation Setting Home-based Participants Home-dwelling persons aged ≥65 years meeting at least one frailty phenotype criteria (n=300). Intervention 12-month, individually tailored, progressive and physiotherapist-supervised, physical exercise twice a week (n=150) vs. usual care (n=149).
