In which phase of cardiorespiratory training is exercise performed at RPE of 3 to 4 and focuses on steady-state training in zone 1?

1. Aerobic-base training

2. Aerobic-efficiency training

3. Anaerobic-endurance training

4. Anaerobic-power training

The correct answer is: Aerobic-base training

The correct choice is based on the characteristics of the aerobic-base training phase, which emphasizes developing a strong foundation for cardiorespiratory fitness. In this phase, exercises are typically conducted at a rate of perceived exertion (RPE) of 3 to 4, which corresponds to a level of intensity where the individual can perform steady-state exercise without excessive fatigue. Focusing on zone 1 means that the heart rate remains within a range that is conducive to building endurance without entering higher intensity zones that would require more recovery or lead to higher levels of exertion. This type of training helps improve the body's ability to efficiently use oxygen, leading to enhancements in overall aerobic capacity and endurance. In contrast, the other training phases involve higher intensities or different focuses, such as improving efficiency (aerobic-efficiency training), developing anaerobic capacity (anaerobic-endurance training), or maximizing power for short bursts (anaerobic-power training). These do not align with the steady-state, lower-intensity training characteristic of aerobic-base training, which is why they are not the correct choices.
