⬌ variability or production durations

⬌ errors made

Beaven et al. 2013 [72]

Recreationally active males (n = 12)

5 s- 25 mL rinse 1.2% caffeine

• 5 s- 25 mL rinse 6% CHO

Sinclair and Bottoms 2014 [74]

Healthy males (n = 12)

5 s- 25 mL rinse 0.032% caffeine

5 s- 25 mL rinse 6.4% CHO

*↑ distance cycled during the caffeine mouth rinse trial (16.2 ± 2.8 km) was significantly greater compared to placebo trial (14.9 ± 2.6 km).

There was no difference between CHO and caffeine trials
