During a push-up with a 4-3-2-1 repetition tempo, how long is the eccentric muscle action performed?

In the context of a push-up performed with a 4-3-2-1 repetition tempo, the eccentric muscle action refers to the phase where the muscles lengthen while controlling the descent of the body. The repetition tempo is typically structured in a way that the first number indicates the time spent on the eccentric phase.

Therefore, with a tempo of 4-3-2-1, the "4" represents the 4 seconds spent on the eccentric phase of the push-up. This phase occurs as you lower your body towards the ground. The controlled, slower pace during this section can enhance muscle tension and promote strength gains, which is why emphasizing a longer eccentric duration is often utilized in strength training protocols.

Understanding the tempo in this way is crucial for accurately applying training principles and maximizing the benefits of resistance exercises. The other numbers in the sequence correspond to the isometric hold, the concentric phase, and any pause before starting the next repetition, but they do not pertain to the eccentric action itself.
