Interactions of sports immunometabolism, training load, and nutrition can affect athletes' performance and psychological behaviors changes in the training, matches, and decisions. Changes that are associated with various physiological factors such as nutrition, heart rate, hormone secretion, immune system function, type of sport, psychological factors such as stress, sleep quality, anxiety, and coaches' behavior with athletes or training environment. Changes that are associated with various physiological factors such as nutrition, heart rate and the Borg rating of perceived exertion (RPE) scale as a training load, hormone secretion [e.g., GH, IGF1, testosterone (T), cortisol (C), and (T/C ratio)], immune system function [pro-inflammatory cytokines status (e.g., IL-1ß, IL-6, and TNF-a)], type of sport (individual or sports teams), psychological factors such as well-being or wellness (Hopper index Questionnaires and so on) stress, sleep quality, anxiety, and coaches' behavior with athletes or training environment. All these features can be used to monitor athletes and to prevent sports injuries, reduce psychological stress, change mood, and improve athletic performance in competitions. On the other hand, the role of dietary and ergogenic supplements in improving the recovery and manage fatigue of athletes between training sessions and fluid intake is very important to prevent the athlete from non-functional over-reaching state, overtraining syndrome, and psychological disorder condition.
Our goal in this Research Topic is to gather scientific evidence that can be translated into practical advice for coaches and athletes, so that it can help improving performance in training and during competitions.
Thus, we are particularly interested in studies that explore:
· Sport psychology, immunometabolism, nutritional supplements used by athletes to prevent non-functional over-reaching state and/or overtraining syndrome;
· Psychological behaviours and immune system acute or chronic adaptations that can help preventing non-functional over-reaching state and/or overtraining syndrome;
· Qualification the controlling training load and well-being status for prevention of non-functional over-reaching state and/or overtraining syndrome.
