Question

The ergogenic effect of caffeine

a. does not vary between individuals.
b. is influenced by gender.
c. is due to a decrease in fat metabolism.
d. is dose dependent (i.e., depends upon on the amount of caffeine ingested).

Answer 1

The ergogenic effect of caffeine is dose dependent, meaning it depends on the amount of caffeine ingested. Moderate doses of caffeine can improve athletic performance and increase fat oxidation during aerobic exercise.

Step-by-step explanation:

The ergogenic effect of caffeine is dose dependent, meaning it depends on the amount of caffeine ingested. Moderate doses of caffeine, around 5 mg/kg, can improve sprint performance, cycling and running time trial performance, endurance, and cycling power output. Caffeine also increases fat oxidation during aerobic exercise, particularly in individuals with low physical fitness.
