Heart rate analysis for pre-performance routine in darts game

This paper presents the analysis of the heart rate data for the pre-performance routine (PPR) to improve throwing accuracy in a darts game. We conducted a detailed study to establish a relation between the heart rate change during PPR, timing of heartbeat, and throwing accuracy. It was confirmed that heart rate tends to increase by performing a set of actions just before the game, leading to higher scores. This set of actions is considered as PPR. It was also observed that PPR-led throwing at the timing of heartbeat resulted in improved scores. A system that provides a user with the sound of a heartbeat was developed using a smart watch. The effectiveness of the system was verified and compared in an experiment with a metronome that produces audible sounds at regular intervals and is not related to heartbeat.
