Effect of mouth rinsing and ingestion of carbohydrate solutions on mood and perceptual responses during exercise

Figures & data

Fig. 1 Ratings of perceived exertion (RPE) measured at various intervals throughout the time trial. CHOI – carbohydrate ingestion trial; CHOR – carbohydrate mouth rinse trial; PLAI – placebo ingestion trial; PLAR – placebo mouth rinse trial

Fig. 2 a Feeling scale (FS; ‘pleasure-displeasure’) and b felt arousal scale (FAS; ‘activation’) ratings during the time trial. CHOI – carbohydrate ingestion trial; CHOR – carbohydrate mouth rinse trial; PLAI – placebo ingestion trial; PLAR – placebo mouth rinse trial

Fig. 3 Profile of mood states (POMS); a overall (composite) POMS score; b fatigue subset ratings only; c vigour subset ratings only. CHOI – carbohydrate ingestion trial; CHOR – carbohydrate mouth rinse trial; PLAI – placebo ingestion trial; PLAR – placebo mouth rinse trial

Fig. 4 Plasma glucose measured after each 25% of exercise completed. CHOI – carbohydrate ingestion trial; CHOR – carbohydrate mouth rinse trial; PLAI – placebo ingestion trial; PLAR – placebo mouth rinse trial. * indicates significantly higher ratings in CHOI relative to other trials (P < 0.05)
