INTRODUCTION: Table tennis player performance has already been defined in the literature by several aspects such as tactics, equipment, and technique. Ball quality of stroke could be one of them, especially ball speed, rotation, or even precision. Few studies have investigated the relationship between those indicators on different stroke conditions and under neuromuscular or mental fatigue which has been proven to be an influential factor in stroke performance. This study aims to observe the effect of fatigue on the relationship between these performance indicators and their evolution in fatigue. METHODS: Nine young table tennis players men (age :15 ±1.5y; French ranking points: 2103±344) from a French table tennis national centre were selected to perform three experimental trials in a randomized order: a control session, a neuromuscular fatigue session, and a mental fatigue session. Neuromuscular fatigue was induced in biceps brachii. Participants realized ten biceps eccentric contractions with a load of 90% of their 1RM until they reached a 15% loss of their reference MVC. Mental fatigue session consisted of a mentally fatiguing task (90 min AX-CPT test), while the control session required participants to watch a 90 min neutral movie. Each session, athletes had to realize a pre/post table tennis performance test. Players had to perform four exercises using backhand and forehand strokes with backspin and topspin balls. They had to hit thirty balls thrown by a ball launcher. Players must hit the ball cross-court aiming for targets on either side of the table. Ball speed, spin, impact position, and racket acceleration profile were measured during the tests. Subjective feeling of Fatigue and perceived exertion levels were assessed during the sessions. RESULTS: . Measured RPE and feeling of fatigue were significantly higher post Neuromuscular and Mental fatigue protocols. First results, shows that the ball spin appears to be highly correlated with ball speed (r=0.96, p
