Relationships between facial temperature changes, end-exercise affect and during-exercise changes in affect: A preliminary study

摘要

The present study was performed as an evaluation of the relationships between changes in facial temperature and self-reported pleasure-displeasure during an acute aerobic exercise bout. Ninety-two students performed a 10-minute long session of cycle ergometry at 80-85% of age-predicted maximal heart rate. Using infrared thermography and a single-item measure of pleasure-displeasure (the Feeling Scale, FS), facial temperature and the FS score were sampled at the beginning (Min1:00) and at the end of the exercise session (Min9:00). Statistical analyses revealed that cheek (but not forehead) temperature was higher at the end of the exercise bout compared to Min1:00 (it increased by about 5%). Change in cheek temperature was negatively related to end-exercise affect (beta = -0.28, P < 0.001) and to during-exercise affective changes (beta = -0.35, P < 0.001). No significant relationship with forehead temperature was found. Some of the possible reasons for this differential effect as well as theoretical and practical implications of our findings are discussed.
