What does "tempo" refer to in resistance training?

• A. The number of sets performed
• B. The speed of exercise execution
• C. The duration of rest between sets
• D. The overall workout length

Answer: (B)

In resistance training, "tempo" specifically refers to the speed at which an exercise is performed during each repetition. Tempo is often expressed using a four-number system, where each number corresponds to a phase of the lift, such as the eccentric (lowering) phase, the isometric (pause), and the concentric (lifting) phase. For instance, a tempo of 2-1-1 means a two-second lowering phase, a one-second pause, and a one-second lifting phase.

Controlling tempo can have significant effects on muscle activation, training intensity, and overall outcomes in resistance training. By manipulating tempo, practitioners can emphasize different aspects of strength training, such as building endurance, increasing strength, or maximizing power. Therefore, understanding and applying the correct tempo is essential for optimizing performance and achieving specific training goals.

The other options refer to different aspects of resistance training, such as volume (sets performed), rest intervals between sets, and overall workout duration, but they do not capture the concept of tempo as it relates to exercise execution speed.
