Editorial: Fatigue assessment in sport

To avoid excessive exercise-induced load and overtraining, or to facilitate a proper recovery after a sport-related injury, it is essential to adequately monitor exercise intensity and manage fatigue. In this perspective, sport science and technology continuously propose advanced techniques to tackle the challenges of coaches and athletes. It is crucial to rely on objective measurements of fatigue in order to tailor training sessions and recovery programs to the specific needs of each individual professional or amateur athlete. However, fatigue is a multi-faced phenomenon requiring innovative and integrated approaches, including the evaluation of the manifestations of muscle fatigue in surface electromyograms recorded during an exercise, and the study of central and peripheral components of fatigue. This Research Topic aims to provide solutions beyond the state of the art for accurately and effectively monitoring fatigue during sporting performance and exercise training. Indeed, properly managing fatigue and fatigue-related symptoms can be a key factor for limiting athletes' musculoskeletal problems or altered proprioception that can cause traumas. This Research Topic was not limited to contributions related to elite athletes and elite para-athletes but analyzed also studies related to amateur practitioners of physical activities for fitness and recreational purposes. The present research topic collected research articles covering different sports, themes and issues. Within these articles, we identified three areas of research with respect to the impact of fatigue assessment in sport: fatigue in running, fatigue in swimming, techniques to manage fatigue.
