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…
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…
Resonancia nuclear magnética en roturas del ligamento cruzado anterior : sensibilidad y concordancia con hallazgos artroscópicos
2018
To estimate the sensitivity of magnetic resonance imaging (MRI) as a diagnostic test in anterior cruciate ligament (ACL) injuries, as well as its correlation with arthroscopic findings. Methods. Retrospective analysis of 270 patients who underwent ACL reconstruction surgery in our health department between 2007 and 2017. ACL injuries were diagnosed by radiologists specialized in musculoskeletal pathology, while the correlation between radiological and arthroscopic findings was determined through statistical analysis. Results. The sensitivity of the MRI regarding diagnosis of ACL injuries was 88.5%. In addition, the correlation between radiologic and arthroscopic findings was 73.3%. In 71% o…

Size-related mortality during overwintering in cavity-nesting ant colonies (Hymenoptera: Formicidae)
2016
The ongoing process of climate change will result in higher temperatures during winter and therefore might increase the survival of overwintering invertebrates. However, the process may also lead to a reduction in snow cover and expose overwintering invertebrates to lower temperatures, which could result in higher mortality. During a field experiment, I investigated the effects of a reduction in snow cover on the survival of the ant Temnothorax crassispinus, which overwinters in nests located on the ground. Ant colonies differed in the survival rate of the workers in the experimental (from which snow cover was removed) and control group. In the control group, the survival rate was unrelated…
Assessment of aerobic and anaerobic thresholds in five different technique specific incremental treadmill tests in cross country skiers
2016
The use of incremental tests to exhaustion is widely accepted in the field of exercise physiology in the assessment of athletes. These tests which can measure a number of physiological parameters can help coaches and athletes optimize training. Blood lactate concentrations (bLa) corresponding to heart rate (HR) provides insight on the athlete’s aerobic threshold (AerT) and anaerobic threshold (AnT). Cross country skiing is a sport where the selection of technique may influence the HR at which AerT and AnT occurs, eliciting higher bLa corresponding to lower HR depending on technique. Because of this, laboratory testing is crucial to provide coaches and athletes with the necessary information…
Heart rate recovery after maximal and submaximal exercise
2012
Pasi Karjalainen (2012). Heart rate recovery after maximal and submaximal exercise. Department of Biology of Physical Activity, University of Jyväskylä, Master thesis in exercise physiology, 76 pages. Heart rate recovery (HRR) after exercise reflects autonomic control of the heart. Heart rate recovery (HRR) has shown to have prognostic value among asymptomatic populations and patients with diseases. In addition, changes in HRR may reflect the effects of training load. The role of parasympathetic reactivation in decrease of heart rate (HR) is known to be strong immediately after the cessation of exercise. It is also shown that HRR is affected by the activity of the sympathetic system that is…
Heart rate variability as a physiological indicator or mental toughness
2016
Mental toughness is gaining prominence in sport psychology since athletes themselves, coaches, members of the press, sports commentators and sports psychologists have cited mental toughness as one of the most important psychological characteristics in elite sports. Even so, an extensive review of the available literature leads to the conclusion that there is a lack of a precise and widely accepted definition of mental toughness, while its conceptualization remains challenging. Therefore, based on the existing literature concerning physiological toughness (Dienstbier, 1989), this study examines through an innovative psychophysiological perspective how mental toughness operates, and thus cont…
