Badminton is an intermittent sport marked by rapid and explosive actions, demands specialized movement patterns involving quick accelerations, decelerations, and direction changes over short distances. The forehand overhead jump smash, a high-speed and powerful motion, plays a pivotal role in various racket sports. This study aimed to examine the influence of cardiovascular fatigue on kinematic variables during the execution of the overhead jump smash in badminton. In this study, we used a descriptive quantitative method. The study included 12 male badminton players, with an average age of 19.4 ± 1.6 years, height of 1.73 ± 0.12 m, and weight of 60.8 ± 3.7 kg. Three high-resolution handycams, the motion software Frame DIAZ IV, and 14 manual markers were utilized to analyze body segments movements during the jump smash. Fatigue levels were assessed using an ergo treadmill for running tests. The study revealed that shuttlecock velocity was higher in the prefatigue condition. A significant difference showed in compared to the under-fatigue condition compared to the under-fatigue condition. Significant differences were observed in the angle of shoulder internal rotation (p = 0.048) and wrist palmar flexion at the moment of maximal shoulder external rotation phase. Additionally, considerable variations were noted in shoulder internal angular velocity, elbow extension, forearm supination, and wrist dorsi flexion at the moment of maximal shoulder external rotation phase. This study showed that fatigue had a detrimental impact on player performance during the jump smash in badminton, manifesting as reduced shuttlecock speed and alterations in body segment movements. © 2023, Editura Universitatii din Pitesti.
