•Lethargy in body language
•Walking slower than normal

Metabolic Fatigue(Energy Stores)
Tennis examplesExpression of this fatigue
Main causes for fatigue
Type of Fatigue
•Slow feet•Reduced acceleration
•Poor technique and co-ordination.
•Abnormal number of technical mistakes
•Reduced power in shots and strokes
•Reduced localized force production (e.g. slower responses, reduced power)
•After short high intensity sessions, (e.g. weights, plyometrics, complex skill execution, etc.)
•After long training sessions of one hour or more, or after matches greater than two hours.
•Several matches over consecutive days
Neurological FatiguePNS Fatigue(muscles)
Tennis examplesExpression of this fatigue
Main causes for fatigue
Type of Fatigue
•Looses concentration quickly
•Slower at decision making
•Slower anticipation timing (e.g. speed and placement of opponents serve or return)
•Lack of drive
•Slower at processing visual cues
•Low blood glucose levels
•High pressured training session –especially involving rapid decision making and reactions
•Poor motivation (e.g. monotony of training, emotional factors, injury etc.)
Neurological Fatigue
CNS Fatigue(brain)
Tennis examplesExpression of this fatigue
Main causes for fatigue
Type of Fatigue
•Player shows a definite lack in confidence during play and also off court
•Tends to be more negative than usual especially in self-talk, and with body language
•Players’communication seems different (e.g. pre occupied with matters away from tennis that affect focus and concentration.)
•Player loses self-confidence or self esteem
•Poor interaction and deteriorating communication with other players and coaches
•Increased signs of anxiety, negative attitudes, etc.
•Lack of squad cohesion, personality conflicts etc.
•Competition pressures, event venue, residential conditions, parents, coach, media, etc.
•Other lifestyle stresses – home, school exams, personal relationships
Psychological Fatigue(emotional, social, cultural)
Tennis examplesExpression of this fatigue
Main causes for fatigue
Type of Fatigue
•Player takes longer than usual to get rhythm on court.
•Unforced errors in the first 15 min are well above normal
•Tired eyes and eye strain
•Poor tracking of the ball
•Players are slower to start
•Fatigue sooner than normal especially in the heat
•Visual fatigue from bright or glaring sunlight
•Weather (e.g. wind, heat and sun) increase fatigue
•Disruption of normal routines (e.g. sleep, waking and meal times)
•Sedentary and restricted body movement on long journeys, i.e. 30 min or more
•Adapting to different climates and time zones
