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…

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). Main outcome Measures Functional Independence Measure (FIM), Short Physical Performance Battery (SPPB), handgrip strength, instrumental activities of daily living (IADL), and self-reported falls and physical activity (o…

Effects of hormonal contraceptives on physical performance and body composition

2016

The purpose of the present study was to examine the effects of hormonal contraceptive use on neuromuscular, cardiorespiratory and body composition adaptations following combined strength and endurance training period. Methods. Nineteen recreationally active women; 11 who had at least one year of hormonal contraceptive use (age 294 yr; BMI 212 kg/m2; VO2max 444 ml/kg/min) and 8 who had never used hormonal contraceptives (age 315 yr; BMI 222 kg/m2; VO2max 414 ml/kg/min) participated in the present study of combined strength and endurance training for 10 weeks. Training consisted of two maximal and explosive strength training sessions, and two high-intensity interval training sessions pe…

Motives for competitive sports participation in masters track and field athletes : Impact of sociodemographic factors and competitive background

2022

Objectives Masters athletes due to their lifelong engagement in sport represent a unique group to study motivation for regular physical activity, but there is less scientific data on the sport motives in masters athletes. Therefore, the aim of this study was to evaluate the association of age, sex, education, nationality, competitive background and training amount with sport motives of masters track and field athletes. Methods 811 (254 women) athletes aged 35–89 years participated in European Veterans Athletics Championships in the year of 2000. Sport motives were assessed with a questionnaire and categorized into1) well-being, 2) competitive and performance 3) health and fitness motives. R…

Effects of Repeated Sprint Training in Hypoxia on Physical Performance Among Athletes : A Systematic Review

2021

Repeated sprint training in hypoxia (RSH) represents an innovative method in the process of development and improvement of physical performance among athletes. However, there is less scientific data on this topic. The purpose of this systematic review was to investigate the effect of RSH method on motor abilities and performance among athletes, obtain new information, and expand the already known conclusions. The data search was performed of 4 electronic databases for the years 2000-2021 May as follows: Google Scholar, PubMed, Web of Science, and ResearchGate. This search with English language restriction was made by using the following terms, individually/combination: "repeated sprint abil…

Outdoor Mobility and Use of Adaptive or Maladaptive Walking Modifications among Older People

2020

Background. In old age, decline in functioning may cause changes in walking ability. Our aim was to study whether older people who report adaptive, maladaptive or no walking modifications differ in outdoor mobility. Methods. Community-dwelling people aged 75–90 years (N=848) were interviewed at baseline, of whom 761 participated in the 2-year follow-up. Walking modifications were assessed by asking the participants whether they had modified their way of walking 2 kilometers due to their health. Based on the responses, three categories were formed: no walking modifications (reference), adaptive (e.g., walking more slowly, using an aid) and maladaptive walking modifications (reduced frequency…
