This study aimed to establish the affordance and its role in Sepaktakraw serve for coaching implications. Five successful kuda and sila trials performed by two trained male players, captured using a high-speed optical camera system, were analyzed. Variations in kicking limb hip-knee joint coordination to impact suggest ball placements be an affordance in Sepaktakraw serve. This affords what the server must do to ensure optimal foot-to-ball impact velocities without compromising ball velocities. With differences in kicking limb length, this coordination becomes player specific, and the ability to adapt and adjust his coordination pattern depends on such affordance. Servers must vary their movement pattern when executing the kuda or sila serve kicking by manipulating the knee-hip joint coordination with what the affordance affords the servers to do as it swings to impact.
