Does chewing gum mentally help basketball players make foul shots?
Chewing gum increases heart rate and blood pressure through muscular exercise (Farella, Bakke, Michelotti, Marotta &amp; Martina, 1999) and enhances mental performance through improved delivery of glucose to the brain (Stephens &amp; Tunney, 2004).

I could not find any references to embodiment playing a role in the effects of chewing.
