Consideration of the Relationship between Psychological State and Sleep Duration Collected by MENTORE Application in University Karate Team

Abstract

In order to achieve high performance in a game, it is important to adjust physical and psychological conditioning. In particular, psychological conditioning has been evaluated using questionnaires to date. However, the duration of conventional studies is short, and only a few studies have collected data on a daily basis. The purpose of this study was to collect a large amount of daily conditioning data of university karate team members using the MENTORE application, and to analyze and discuss the correlation between the psychological state and sleep duration of university karate team members. Pearson's product-rate correlation coefficients were calculated for six measures of sleep duration and morning POES (Profile of Emotion States) and two measures of psychological state for 17 university karate club members who were the subjects of the study. The results showed that the mean values of Pearson's product-rate correlation coefficients for each measure of sleep duration and POES were similar to an iceberg shape. This suggests that getting enough sleep stabilizes the psychological state and leads to better performance.
