Purpose: To evaluate the effects of muscle fatigue on badminton performance during a smash stroke. Methods: In total, 17 young, well-trained players completed 20 forehand smashes twice (prefatigue and postfatigue protocol), and both speed and precision of the strokes were measured. The fatigue protocol consisted of 10 series of 10 maximal countermovement jumps (3-s rest in between) followed by 8 lunges. Perception of effort and countermovement-jump performance during each series were also measured to assess fatigue. Results: Shuttlecock speed decreased moderately (−3.3%) but significantly after the fatigue protocol (P < .001,
