AB  - Ingesting quality carbohydrates has been shown to be essential for dancers. Given 
      that most dance classes take place in the morning, it has been recommended that 
      dancers eat a well-balanced breakfast containing carbohydrates, fats, and protein 
      as a means of fuelling this activity. The aim of this study was to determine the 
      effect of a moderate glycemic index energy (MGI) bar or a fasting condition on 
      dancers' blood glucose levels and perceived pleasure-displeasure response during 
      the first dance class of the day. In a randomized counterbalanced design, 10 
      female preprofessional dance students took their regular scheduled contemporary 
      dance class, on four separate occasions. On each occasion, they consumed either a 
      commercially prepared carbohydrate (CHO)-dense energy bar (47.3 g CHO) or water 
      (FAST). Plasma glucose responses and pleasure-displeasure affect were measured 
      before and at two time points during the class. Dancers who consumed the MGI bar 
      had significantly greater peak blood glucose levels at all time points than those 
      who fasted (p<0.05). Regarding affective state measures, participants who had 
      breakfast had significantly greater pleasure scores than those who only ingested 
      water(p<0.05). In conclusion, results suggest that CHO with an MGI value 
      positively impacts blood glucose concentrations during a dance class. Further, we 
      conclude that skipping breakfast can have an unfavorable effect on the 
      pleasure-displeasure state of dancers. These findings highlight the impact of 
      breakfast on how one feels, as well as the physiological and metabolic benefits 
      of CHO as an exogenous energy source in dancers.
