Question

The majority of research shows that caffeine has _____________ on a 1RM bench press and leg press, and research is _____________ that caffeine improves the number of repetitions to failure in the bench press and leg press.

Answer 1

Research consistently suggests that caffeine has positive effects on muscular strength and endurance, benefiting exercises like the 1RM bench press and leg press. It acts as a central nervous system stimulant, reducing perceived exertion and potentially increasing repetition numbers to failure.

Step-by-step explanation:

The majority of research indicates that caffeine improves muscular strength and power, which can have positive effects on exercises like the 1RM (one-rep max) bench press and leg press. Specifically, caffeine has been shown to enhance performance on anaerobic tests, which can translate to improved power and strength during these exercises. Furthermore, research is consistent in suggesting that caffeine can improve the number of repetitions to failure for both the bench press and leg press, contributing to enhanced muscular endurance.

Caffeine acts as a central nervous system stimulant by blocking the action of adenosine, which in turn increases alertness and reduces perceived exertion. This reduction in perceived exertion may allow athletes to perform more repetitions before reaching failure. Additionally, caffeine increases basal metabolic rate and fat oxidation, providing further benefits in terms of energy availability during workouts.
