Muskelfunksjon blant unge toppidrettsutøvere i Sør-Norge : Finnes det en sammenheng mellom utvalgte fysiologiske faktorer og muskelstyrke, power og h…
2019
Masteroppgave idrettsvitenskap ME517 - Universitetet i Agder 2019 Background: Muscle strengthand poweris a determining feature of performance in many different sports and thephysiologicalfactors that affect muscle functionare many. Previous studies have mostly concernedadult athletes, while researchfeaturing young elite athletes or differences between sports have been scarce. Purpose: The study’s purposeis to investigate possibleconnectionsbetween physiological factors such as resting metabolic rate, protein intake, and fat-free mass and muscle functionamong young elite athletes in southern Norway.Differences between sport-groupswere alsoinvestigated. Method: A total of 36young elite athlet…
Mobility and muscle strength in male former elite endurance and power athletes aged 66−91 years
2017
The aim of this cross-sectional study was to compare mobility and muscle strength in male former elite endurance and power athletes aged 66-91 years (n = 150; 50 men in both former elite athlete groups and in their control group). Agility, dynamic balance, walking speed, chair stand, self-rated balance confidence (ABC-scale), jumping height, and handgrip strength were assessed. Former elite power athletes had better agility performance time than the controls (age- and body mass index, BMI-adjusted mean difference -3.6 s; 95% CI -6.3, -0.8). Adjustment for current leisure time physical activity (LTPA) and prevalence of diseases made this difference non-significant (P = 0.214). The subjects i…
Sprint mechanical variables in elite athletes: Are force-velocity profiles sport specific or individual?
2019
Purpose The main aim of this investigation was to quantify differences in sprint mechanical variables across sports and within each sport. Secondary aims were to quantify sex differences and relationships among the variables. Methods In this cross-sectional study of elite athletes, 235 women (23 ± 5 y and 65 ± 7 kg) and 431 men (23 ± 4 y and 80 ± 12 kg) from 23 different sports (including 128 medalists from World Championships and/or Olympic Games) were tested in a 40-m sprint at the Norwegian Olympic Training Center between 1995 and 2018. These were pre-existing data from quarterly or semi-annual testing that the athletes performed for training purposes. Anthropometric and speed-time sprin…
Mental health and well-being during COVID-19 lockdown: A survey case report of high-level male and female players of an Italian Serie A football club
2021
Objectives: To describe high-level footballers’ levels and changes in mental health and well-being throughout a 8-week period of lockdown and restricted training during the COVID-19 pandemic. Method: One-hundred and one players belonging to four teams (women's and men's, first and U19 teams) of the same Italian Serie A club participated in the study. Data were collected through an online questionnaire, and administered at 2, 3, 5, 7 and 9 weeks after the start of the lockdown. Well-being, positive and negative affects measurements were examined. Results: Across the five measures, 36% of players reported clinical levels in depressive symptoms (scores ≤50) on at least one occasion. Thirteen p…
The Mediating Role of Self-Efficacy in the Relationship between Approach Motivational System and Sports Success among Elite Speed Skating Athletes an…
2022
Background: While the association between self-efficacy and sports success has been well established in previous studies, little is known regarding whether the basic approach motivation system contributes to this relationship in athletes. The study examines associations between self-reported temperamental approach disposition, self-efficacy, and predispositions to sports success in athletes. Methods: A cross-sectional study was performed between August 3 and 30 November 2020. The participants were 156 athletes, aged 16–34 years (M = 21.57, SD = 3.58, 41.67% women), in two groups: 54 elite athletes in speed skating (EASS) and 102 physical education students (PES). The online survey consisted…
Randomized response estimates for doping and illicit drug use in elite athletes.
2008
Abstract Background To date, there are estimates for the percentage of unknown cases of doping and illicit drug use in fitness sports, but not for elite sports. This can be attributed to the problem of implementing questionnaires and surveys to get reliable epidemiological estimates of deviant or illicit behaviour. Methods All athletes questioned were subject to doping controls as members or junior members of the national teams. In order to estimate the prevalence of doping and illicit drug abuse, the athletes were either issued an anonymous standardized questionnaire (SQ; n = 1394) or were interviewed using randomized response technique (RRT; n = 480). We used a two-sided z -test to comp…
Use of Alcohol and Alcohol-related Morbidity in Finnish Former Elite Athletes
2017
Introduction: The effect of a history of competitive sports on later use of alcohol and occurrence of alcohol-related diseases is poorly known. We investigated how a history of elite level sports was associated with alcohol consumption in middle-age and with alcohol-related morbidity and mortality. Methods: The occurrence of alcohol-related diseases and deaths were followed using national registers from 1970 to 2008 among Finnish male former elite athletes (n = 2202) and matched controls (n = 1403) alive in 1970 (mean age = 45.1 yr). Hazard ratios were calculated by Cox proportional hazards model. In 1985, surviving participants questionnaire-reported their alcohol consumption and engagemen…
A feasibility study of application and potential effects of a single session transcranial Direct Current Stimulation (tDCS) on competitive anxiety, m…
2020
Objective : To examine feasibility and potential effects of a single session tDCS over the dorsolateral prefrontal cortex (DLPFC) on competitive anxiety, mood state, and autonomic and endocrine stress responses in elite archer athletes under a real world competition. Methods : Twelve male elite archers volunteered to participate in this pilot trial. Participants were randomized in order to take left anodal DLPFC, left cathodal DLPFC, or sham stimulation (the F3 or F4 areas according to the 10/20 EEG International System) in a within-subject study design. This study included three official competitions. About 45 min before the competition, the tDCS stimulation process was started and the par…
Evaluating the (Your Country Here) Olympic Medal Count
2013
An Olympic Games is a measurable test of a nation´s sporting power. Medal counts are the object of intense scrutiny after every Olympiad. Most countries celebrate any medal with national glee, since 60% of competing countries will win none. In 2012, 10% of the competing countries won 75% of all medals. Despite this concentration among a few countries, more countries are winning more medals now than 20 years ago, thanks in part to athlete-support and -development programs arising around the globe. Small strong sporting countries like Norway are typified by fairly large variation in medal results from Olympiad to Olympiad and a high concentration of results in a few sports. These are importan…
Prevalence of rapid weight loss in Olympic style wrestlers
2022
Background: The methodology applied for rapid weight loss (RWL) among elite wrestlers is quite unexplored. Therefore, the aim of this study was to analyze the prevalence of sources of influence and methods used for RWL and to determine the differences between wrestling styles. Methods: A total of 229 wrestlers who competed at the World Championship held in Belgrade, Serbia, participated in this research. All respondents completed a questionnaire designed to evaluate RWL patterns in combat athletes. Participants were classified according to wrestling style: Greco-Roman, freestyle, and women wrestling. Results: Sixty-nine percent of wrestlers had previously lost weight to compete. Most respon…
