The Female Handball Player
2018
Female hormones fluctuate in concentrations during the menstrual cycle. This has triggered speculations among athletes, coaches, as well as researchers about the hormonal changes that lead to variations in athletic performance and adaptation to training. Many athletes, as in the general population, use oral contraceptives. This has raised questions concerning the suppression of the endogenous circulating female hormones and if the administration of synthetic hormones may have negative impact on athletic performance and training adaptations – or the opposite.
Consumer wearable technologies to identify and monitor exercise-related arrhythmias in athletes
2020
PURPOSE OF REVIEW: The aim of this study was to synthesize the current evidence supporting and against the use of wearable devices to detect underlying heart conditions in athletes and the most significant limitations. RECENT FINDINGS: Although several large studies have been conducted to evaluate the ability of wearables devices to identify atrial fibrillation among the general population, no studies evaluating their ability to detect other exercise-related arrhythmias in athletes are very sparse. Most of the studies or case reports are focused on the wearables' reliability and accuracy compared with standard ECG. Only small studies evaluating the accuracy of one wearable device in athlete…
A taxonomy of dual career development environments in European countries
2020
Research question. The last decade has seen an increase in empirical research associated with dual careers in sport, with a particular focus on understanding and developing individual characteristics which are important to ensure success in sports and education or a vocation. More recent work has, however, also identified the importance of environmental factors in ensuring successful dual career outcomes. The aims of this study, therefore, are to: (a) identify and classify the different types of dual career development environments (DCDEs) and (b) provide outlines of the key features of the environments identified. Research methods. To achieve these aims, this study adopted the procedure of…
Age group athletes in inline skating: decrease in overall and increase in master athlete participation in the longest inline skating race in Europe -…

The aim of this study was to investigate trends in participation, age, and performance in the longest inline race in Europe, the Inline One-E…

Screening for Low Energy Availability in Male Athletes: Attempted Validation of LEAM-Q
2022
A questionnaire-based screening tool for male athletes at risk of low energy availability (LEA) could facilitate both research and clinical practice. The present options rely on proxies for LEA such screening tools for disordered eating, exercise dependence, or those validated in female athlete populations. in which the female-specific sections are excluded. To overcome these limitations and support progress in understanding LEA in males, centres in Australia, Norway, Denmark, and Sweden collaborated to develop a screening tool (LEAM-Q) based on clinical investigations of elite and sub-elite male athletes from multiple countries and ethnicities, and a variety of endurance and weight-sensiti…
Prevalence of relative energy deficiency in sport among well-trained male Norwegian cyclists and long-distance runners
2016
Masteroppgave i idrettsvitenskap - Universitetet i Agder 2016 Introduction Relative Energy Deficiency in Sport (RED-S) links low and reduced energy availability (EA) with negative health and performance consequences, though not well investigated in male endurance athletes. The aim of this study was to investigate the prevalence of RED-S and associated health consequences in well-trained male endurance athletes. Methods Forty-one subjects, cyclists (n=21) and runners (n=20) [age: 40 (31-45) years; BMI: 23.5 (21.4-24.0) kg/m2; body-fat: 14.0% (10.0-16.5%); training volume: 12 (9-16) h/week presented as median + interquartile range] were recruited. Protocol included assessment of bone health, …
Do E-Athletes Move?
2016
This article offers possibly the first peer-reviewed study on the training routines of elite e-athletes with special focus on the subjects' physical exercise routines. The study is based on a sample of 115 elite e-athletes. According to the responses, e-athletes train approximately 5.28 hours every day around the year on the elite level. Approximately 1.08 hours of that training is physical exercise. More than half (55.6%) of the elite e-athletes believe that integrating physical exercise in their training programs has a positive effect on esport performance; however, no less than 47.0% of the elite e-athletes do their physical exercise chiefly to maintain overall health. Accordingly, the s…
Gut Microbiota and Serum Metabolome in Elite Cross-Country Skiers : A Controlled Study
2022
Exercise has been shown to affect gut the microbiome and metabolic health, with athletes typically displaying a higher microbial diversity. However, research on the gut microbiota and systemic metabolism in elite athletes remains scarce. In this study, we compared the gut microbiota profiles and serum metabolome of national team cross-country skiers at the end of an exhausting training and competitive season to those of normally physically-active controls. The gut microbiota were analyzed using 16S rRNA amplicon sequencing. Serum metabolites were analyzed using nuclear magnetic resonance. Phylogenetic diversity and the abundance of several mucin-degrading gut microbial taxa, including Akker…
‘School, family and then hockey!’ Coaches’ views on dual career in ice hockey
2017
Despite the extensive research into coaches’ roles in supporting athletic development and motivation for sport, few studies have examined coaches’ attitudes and practices towards athletes’ dual careers. The present study extends European research into athletes’ dual careers by examining Finnish ice hockey coaches’ attitudes and practices surrounding players’ education. Ten male coaches aged 27–52 participated in semi-structured interviews. The data were analysed with an existential-narrative theoretical framework and with thematic and structural narrative analysis. Three composite vignettes were created entitled ‘supporting athletic development and players in reaching their own goals’, ‘enj…
