Final answer:
Competing in a swimming meet produces heat, more energy, and glucose.
Step-by-step explanation:
When competing in a swimming meet, participants release fuel energy from their muscles. This activity produces heat as muscles contract and work, causing an increase in body temperature. It also produces more energy as the stored energy in the muscles is converted into mechanical energy that propels the swimmer forward. Finally, the activity produces glucose as the muscles break down stored glycogen to provide the necessary fuel for the swimmer's movements.
