Background Backcourt forehand clear stroke is a fundamental technique in badminton, but the biomechanical differences between novice and experienced players are not fully understood. This study aimed to compare the kinematic characteristics of body segment acceleration during the backcourt forehand clear stroke between these two groups. Methods Forty-five participants (22 novice players with less than 2 years of experience and 23 experienced players with over 5 years of competitive experience) were placed with wireless accelerometers on key body segments (foot, calf, thigh, hip, shoulder, upper arm, forearm). Each participant performed 5 backcourt forehand clear strokes, and acceleration data were collected at 100 Hz. The mean values from the 5 repetitions were used for statistical analysis to ensure reliability and reduce variability. Results The results revealed significant differences in movement patterns between the groups. Novices exhibited greater ranges of motion (ROMs) in most body segments, particularly at the hip, thigh, calf, and shoulder, across the x, y, and z axes (p < 0.05). Additionally, novices showed higher maximum and minimum accelerations (p < 0.05). Conclusion These findings suggest that experienced players achieve more efficient movement patterns through refined motor control and reduced excessive motion. This research provides valuable insights for coaching interventions and technique refinement in badminton training programs, particularly for developing players.
