IntroductionThe goal of all sports training is to provide sufficient training loads that improve the athlete's performance (Meeusen, 2006, p.1). Due to training methods, athletes will experience minor fatigue and acute decline. performance (Halson, 2004, p.967). New, creative training methods, developed by coaches, athletes and sports scientists, aim to help improve the quality and quantity of sports training (Kellmann, 2010, p.1). However, these methods have encountered a constant set of obstacles, including overtraining (Kellmann, 2010, p.1). When training stress and adequate recovery time are disproportionate, overtraining will occur (Halson, 2004, p.967). Due to these obstacles, the need for physical and mental recovery in athletics has attracted increasing attention in practice and research (Kellmann, 2010, p.1). In order to fully understand the impact and effect of overtraining, define and establish the difference It is necessary to understand what overtraining is in other conditions, such as surpassing oneself. Overtraining is defined as the accumulation of both training and non-training stress, producing a long-term effect on the athlete's performance capacity, with or without physical and psychological signs and symptoms of overtraining, in which recovery of performance capacity will take weeks or even months (Halson, 2004 p.969). However, overachievement is defined by the accumulation of training and non-training stress having a short-term effect on the athlete's performance capacity, with or without signs and symptoms of physical and psychological overtraining in which the capacity to performance will take days or even weeks to recover. (Halson, 2004, p.969). The difference between overtraining and overreaching is implicitly middle of paper......very (Meeusen, 2006, p.1). Without sufficient recovery, the body will adapt abnormally to training, which will have negative impacts on various biological, hormonal, metabolic, physiological and lymphatic systems (Meeusen, 2006, p.1). Implementing sufficient and adequate recovery is the most important step in gaining positive adaptations to intense training. Recovery allows the athlete to remove the stress of training and allow the muscle to properly heal and recover from the previous training (Smith, 2004, p. 194). Recovery from overtraining syndrome usually lasts a few months, but there are cases in which an athlete never fully recovers from overtraining and the condition becomes chronic (Smith, 2004, p.190). An athlete with overtraining syndrome should only participate in training at a slow pace and only when function and desire to train are present (Smith, 2004, p.. 190).
