In this randomized, prospective monocentric study, 40 subjects with coronary artery disease or hypertension (cardiovascular disease [CVD] group) were assigned to either surgical mask (SM) or class 2 filtering facepiece mask (FFP2). They performed cycle ergometry exercise tests with progressive intensity until exhaustion with the assigned mask and a...

Background During the COVID-19 pandemic, compulsory masks became an integral part of outdoor sports such as jogging in crowded areas (e.g. city parks) as well as indoor sports in gyms and sports centers. This study, therefore, aimed to investigate the effects of medical face masks on performance and cardiorespiratory parameters in athletes. Method...

While sample sizes in elite sports are necessarily small, so are the effects that may be relevant. This conundrum is complicated by an understandable reluctance of athletes to comply with extensive study requirements. In Bayesian analyses, pre-existing knowledge (e.g., from sub-elite trials) can be formally included to supplement scarce data. Moreo...

We aimed to analyze the number and type of contacts involving the risk of respiratory disease transmission during football match play. We analysed 50 matches from different playing levels. Two reviewers evaluated the contacts of all players in each match. We focused on between-player contacts, crowding, actions with potentially increased aerosol an...

Objective: It is unclear whether and to what extent COVID-19 infection poses health risks and a chronic impairment of performance in athletes. Identification of individual health risk is an important decision-making basis for managing the pandemic risk of infection with SARS-CoV-2 in sports and return to play (RTP). Methods: This study aims 1) to a...

Objective To investigate the risk of transmission among potentially infectious SARS-CoV-2-positive football players while participating in training or matches at amateur, youth and professional levels. Methods Between August 2020 and March 2021, football players who tested positive for SARS-CoV-2 and participated in matches or training during the...

We aimed to analyze the number and type of contacts involving the risk of respiratory disease transmission during football match play.We analysed videos of 50 matches from different levels of play (professional, amateur, youth). Two reviewers evaluated the contacts of all players in the field of view in each match. We focused on between-player cont...

The risk of viral transmission of SARS-CoV-2 associated with football (soccer) training and match play is unknown. When a player tested positive, health authorities use different policies for case management extending from continuation of football (“wait and watch” strategy) to a 2-week quarantine for all exposed players and staff. Therefore, studi...

Objective To investigate the underlying causes and regional patterns of sudden death in football (soccer) players worldwide to inform and improve existing screening and prevention measures. Methods From 2014 to 2018 cases of sudden cardiac death (SCD), survived sudden cardiac arrest (SCA) and traumatic sudden death were recorded by media monitorin...

Background Knowledge about causes of sports-related sudden cardiac arrest (SrSCA) may influence national strategies to prevent such events. Therefore, we established a prospective registry on SrSCA to estimate the incidence and in particular describe the etiologies of SrSCA in the general population in Germany. Methods The registration of SrSCA ba...

Purpose Training intensities are frequently prescribed as relative workloads based on a single reference value (e.g. maximum oxygen uptake). However, exercise-induced physical strain is multifaceted and large interindividual variability in intensity markers has been reported for constant load exercise with standardized relative intensity. This ques...

While the ergogenic effect of sodium bicarbonate (BICA) on short-term, sprint-type performance has been repeatedly demonstrated, little is known about its effectiveness during prolonged high-intensity exercise in well-trained athletes. Therefore, this study aims to examine the influence of BICA on performance during exhaustive, high-intensity endur...
