| Outline of Final Research Achievements |
Different physical and mental conditions cause the human heart rate to fluctuate. However, it is difficult to record physiological data in real sports situations without impeding an athlete’s movement, and no effective method has been established for quantifying changes in an athlete’s heart rate that are unrelated to exercise intensity. Using a recently developed wearable bioelectrode (“hitoe”), we performed electrocardiographic and bodily acceleration measurements on baseball and basketball players during actual practice and game situations. We constructed a linear regression model that accurately predicts each player’s current heart rate using acceleration data. By subtracting the estimated heart rates (“physical HR”) from actually measured HR, we estimated mentally affected heart rate of the players during a game. Our proposed method effectively detected increases in the players’ heart rates that were related to the game situations rather than to the exercise intensity.
