Qualitative Analysis of Concentration Level in Throwing Using Simple Brain-Wave Sensor

This paper describes a qualitative analysis of the concentration level required to throw an object at a specific target, such as the free throw in basketball or darts games, using a simple brain-wave sensor. The qualitative analysis does not focus on quantity, but on qualitative changes, such as increasing, decreasing, or stabilizing. The analysis allows us to clarify the essential features of subjects where standards are individually different, such as brain waves or concentration levels. Therefore, the author analyzes the differences between experts and novices while throwing. Furthermore, the author analyzes the influence of pre-performance routines (PPRs), which involve performing certain determined motions before throwing, and are often executed in sports for the purpose of removing stress or raising concentration. The analysis reveals a concentration-stabilizing phenomenon where the concentration level becomes stabilized prior to throwing. The author also finds that the phenomenon appears more conspicuously in the case of experts and PPRs.
