Associations between maximal strength, sprint, and jump height and match physical performance in high‐level female football players
(Journal article; Tidsskriftartikkel; Peer reviewed, 2021-08-06)Studies on females’ decisive physical components to physical match-play performance are sparse and only emphasize endurance tests. Thus, the influence of maximal strength and power on physical performance during match-play is currently unknown. The aim of this study was to assess the association between one repetition maximum (1RM) half squat strength, 5-, 10-, and 15-m sprint times, countermovement ... -
Associations between physical activity, left atrial size and incident atrial fibrillation: the Tromsø Study 1994–2016
(Journal article; Tidsskriftartikkel; Peer reviewed, 2022-01-24)Aims: Left atrial (LA) enlargement is an independent risk factor for atrial fibrillation (AF). Interestingly, some athletes have increased risk of AF, which may be linked to LA enlargement; however, little is known about the relationship between LA enlargement and AF risk at moderate-level physical activity (PA). We aimed to explore the associations between PA, LA size and risk of incident ... -
Cross-sectional associations between accelerometry-measured physical activity, left atrial size, and indices of left ventricular diastolic dysfunction: The Tromsø Study
(Journal article; Tidsskriftartikkel; Peer reviewed, 2020-12-31)Whereas left atrial (LA) enlargement is an independent predictor for adverse cardiovascular events and all-cause mortality, this is regarded a physiological adaption of exercise. Paradoxically, LA size in athletes may overlap the enlargement observed in patients with cardiac pathology. Current knowledge is mainly derived from studies of athletes, and little is known about cardiac adaptations to ... -
Females display lower risk of myocardial infarction from higher estimated cardiorespiratory fitness than males. The Tromsø Study 1994-2014
(Journal article; Tidsskriftartikkel; Peer reviewed, 2024-01-06)Objective - To examine the dose-response association between estimated cardiorespiratory fitness (eCRF) and risk of myocardial infarction (MI).<p> <p>Patients and Methods - Adults who attended Tromsø Study surveys 4-6 (Janurary 1,1994-December 20, 2008) with no previous cardiovascular disease were followed up through December 31, 2014 for incident MI. Associations were examined using restricted ... -
Improved maximal strength is not associated with improvements in sprint time or jump height in high-level female football players: a clusterrendomized controlled trial
(Journal article; Tidsskriftartikkel; Peer reviewed, 2019-09-17)<i>Background</i> - Maximal strength increments are reported to result in improvements in sprint speed and jump height in elite male football players. Although similar effects are expected in females, this is yet to be elucidated. The aim of this study was to examine the effect of maximal strength training on sprint speed and jump height in high-level female football players.<p> <p><i>Methods</i> ... -
Intra‐arterial blood pressure traits during and after heavy resistance exercise in healthy males
(Journal article; Tidsskriftartikkel; Peer reviewed, 2019-07-29)This randomized within‐subjects crossover‐designed study evaluated intra‐arterial blood pressure (BP) traits in seven healthy males (24 ± 1 years) during heavy resistance exercise (HRE) to failure (10 × 5 repetitions, 5RES) and not to failure (10 × 3 repetitions, 3RES), both at 5RM load. By combining few repetitions, avoidance of Valsalva maneuver, and restricting the duration of each contraction, ... -
Longitudinal Associations Between Cumulative Physical Activity and Change in Structure and Function of the Left Side of the Heart: The Tromsø Study 2007–2016
(Journal article; Tidsskriftartikkel; Peer reviewed, 2022-05-12)Background: Current knowledge about the relationship between physical activity (PA) and cardiac remodeling is mainly derived from cross-sectional studies of athletes, and there is a knowledge gap of this association in the general adult and elderly population. Therefore, we aimed to explore the longitudinal association between cumulative PA and change in cardiac structure and function in a general ... -
Occupational physical activity and risk of mortality in women and men: the Tromsø Study 1986–2021
(Journal article; Tidsskriftartikkel; Peer reviewed, 2023-11-01)Objective - Associations between occupational physical activity (OPA) and mortality risks are inconclusive. We aimed to examine associations between (1) OPA separately and (2) jointly with leisure time physical activity (LTPA), and risk of all-cause, cardiovascular disease (CVD) and cancer mortality, over four decades with updated exposure and covariates every 6–8 years.<p> <p>Methods - Adults ... -
Physical activity and the structure and function of the left side of the heart
(Doctoral thesis; Doktorgradsavhandling, 2023-03-16)Current knowledge about the relationship between exercise and cardiac remodelling is mostly based on studies of athletes. Little is known about cardiac adaptations to moderate doses of exercise in the general adult and elderly population, and whether exercise-induced cardiac remodelling is a benign physiological adaption of exercise or part of a pathophysiological mechanism. The main objective of ... -
Physiological Comparisons of Elite Male Visma Ski Classics and National Level Cross-Country Skiers During Uphill Treadmill Roller Skiing
(Journal article; Tidsskriftartikkel; Peer reviewed, 2018-11-16)Longer distance cross-country ski (14–220 km) races such as the Visma Ski Classics (VSC) has recently gained attention in addition to the traditional Olympic distances (5–50 km) associated with cross-country (XC) skiing. These long-distance races are characterized by extensive use of the upper body while double poling (DP). While there is a substantial amount of research on Olympic distance XC skiing, ... -
Risk of atrial fibrillation and stroke among older men exposed to prolonged endurance sport practice: a 10-year follow-up. The Birkebeiner Ageing Study and the Tromsø Study
(Journal article; Tidsskriftartikkel; Peer reviewed, 2022-11-17)<p><b> Aims</b> Endurance sport practice is associated with a high prevalence of atrial fibrillation (AF), which increases the risk of stroke in the general population. However, stroke risk in endurance athletes with AF is sparsely investigated. Most studies have been limited by design and are largely restricted to younger and middle-aged populations. Thus, we aimed to investigate AF and stroke ... -
Seasonal variations in physical activity among Norwegian elementary school children in Arctic regions
(Journal article; Tidsskriftartikkel; Peer reviewed, 2021-11-21)The aim of this study was to measure seasonal variations in physical activity (PA) during Polar Nights (PN) and Polar Days (PD) among elementary school children in the Arctic regions of Norway. One hundred and seventy-eight schoolchildren from 1<sup>st</sup>, 3<sup>rd</sup>, 5<sup>th</sup> and 7<sup>th</sup> grade participated in the study. Physical activity was measured for seven consecutive days ... -
Ski Skating Race Technique—Effect of Long Distance Cross-Country Ski Racing on Choice of Skating Technique in Moderate Uphill Terrain
(Journal article; Tidsskriftartikkel; Peer reviewed, 2020-07-14)The aim of this study was to investigate the effect of prolonged ski racing using skating style on technique choice in a transition section among female and male high-level skiers. Fifty three national-to-elite level skiers (20 females: 26.7 ± 4.8 years, 167.0 ± 6.5 m, 61.0 ± 5.1 kg, and 75.5 ± 68.8 FIS points; 33 males: 25.2 ± 3.5 years, 179.0 ± 5.2 cm, 73.1 ± 5.7 kg, and 73.7 ± 63.2 FIS points) ...
