During which Phase of OPT should the exerciser be most concerned with increasing the speed (repetition tempo) of exercises?

The focus on increasing speed, or repetition tempo, is particularly important during the Power phase of the OPT model. In this phase, the primary goal is to enhance athletic performance by developing the ability to generate force quickly. This involves incorporating explosive movements and increasing the velocity of exercises, which helps in improving overall power and speed.

In addition to speed, exercises during this phase typically involve a combination of strength and coordination, where the emphasis is on performing movements that require rapid and explosive actions. This aligns with the goals of Power training, which seeks to improve the power output by challenging the muscles not just in terms of strength, but also in their ability to apply that strength rapidly.

Thus, during the Power phase, practitioners focus on mastering the timing and tempo of movements, which is essential for athletes and individuals aiming to improve their performance in high-intensity sports and activities.
