The effects of mental fatigue on sport-related performance It is known that psychic fatigue increases the subjective fatigue feeling and reduces cognitive performance, but its influence on physical performance is barely understood. The aim of this chapter was to review the results of 29 studies published between 2009 and April 2018 and deal with the effects of intellectual exhaustion on the sports performance.All studies taken together seems that mental fatigue affects endurance, motorized and decision ability.However, maximum force production is not reduced in mental fatigue. These observations suggest that spiritual fatigue affects the sports-related performance in stress with submaximal intensity and not for loads with maximum and supramaximal intensity.
The negative influence of mental fatigue on submaximal stress seems to be conveyed by an increased perception of effort. Future studies should now identify the physiological changes that are caused by mental fatigue and are responsible for the increased perceived effort.
