ABSTRACT

This paper reports on the decay in shuttlecock velocity after smash and slice shots performed by elite and international players, based on the analysis of videos captured on a badminton court with high-speed cameras. The trajectories of feather shuttlecocks show an exponential decay in velocity and an exponential increase in time-of-flight with distance, in accordance with the equation of motion of a shuttlecock subjected to high drag. The initial speed, which can exceed 500 km/h, is reduced by half every 3.35 m, depending on the physical parameters of the shuttlecock characterized by a speed index. The videos show that plastic shuttlecocks, which are more resistant than feather shuttlecocks, deform at high speeds. The resulting decay of their drag coefficient with increasing speed makes them unsuitable for high-level play. The study also shows that the spin induced by the slice shots of left-handed players or the reverse slice shots of right-handed players slows the shuttlecock down.

研究问题

• RQ1 What is the form of shuttlecock velocity decay after smash and slice shots in high-level badminton?
• RQ2 How does shuttlecock type (feather vs plastic) affect drag coefficients and decay rate?
• RQ3 How does spin induced by slice shots influence shuttlecock deceleration?

主要发现

• Shuttlecock velocity decays exponentially with distance after smash and slice shots.
• Time-of-flight increases exponentially with distance.
• Initial speeds can exceed 500 km/h and halve roughly every 3.35 m.
• Plastic shuttlecocks deform at high speeds and show drag coefficient changes that reduce usefulness for high-level play.
• Slice-induced spin, especially from left-handed or reverse slice shots, slows the shuttlecock.
• Decay behavior aligns with a drag-dominated motion model for high-speed shuttlecocks.
